[Q] My BA makes strange HF noise - MDA III, XDA III, PDA2k, 9090 General

I have a small problem with my BA. Somehow it started making some strange high frequency (buzzing) noise. Before last few days it was working very good with each ROM I installed. First I thouhgt that the source of mentioned noise is the speaker, but I was wrong. Source is in the bottom of device, somewhere beneath the screen, just above the mail button. Now, even when it just lies down on the table, screen flashes, and noise starts and some how turns off after 30, 40 seconds all by itself. Also, my battery life is reduced from two days to less than 1 day as a result of this issue. I dont know what shuld I do? Can anyone help me?

Specs please
How old is the device ?
Are there dark (or darker) spots at the edge(s) of the screen ?
Have you run the device at maximum lighting level ? - How long until the Backlight goes to powersave ? ... etc.
I assume - lacking further information - that the lighting is failing.
To my knowledge, there's a CCFL in the LCD I... that'll age over time and then show spots and flickering.
If you _can_ swap the CCFL you'll probable save your inverter ... CCFLs are relatively cheap elements (around USD 20 for 40cm which fits a 18.4" HD TFT Screen), though I have no idea how much a CCFL for the 9090 will amount to.
cf. to e.g. alibaba.com search for qtek 9090 lcd
eBay might help, too.
Good luck...

.:: HELP Appreciated ::. Universal - WHITE SCREEN Problem...

.:: HELP Appreciated ::.
Hello Tech GURUS,
I returned from a long tour (I kept my XDA EXEC at home) & found that my XDA EXEC has got a problem of WHITE SCREEN!! Nothing is Displayed!!
May be brother's childrens or anyone of my friend accidentally did it in my absence(Sorry I'm NOT Sure). May be they pivoted (Turned) the screen in a WRONG DIRECTION!
That doesn't matter WHO DID IT, But the problem screwed my head & I started to trace the problem.
Symptoms:
1) Only WHITE SCREEN(with LCD Backlight), Nothing Else.
2) Charges perfectly through USB & also from Charger.
3) When I connects it to ACTIVE SYNC, it Syncs fine & I can able to explore the files/folders. Copy from & to the handset memory is also works fine.
4) Tried to enter into BOOTLOADER Mode(by pressing Light+Power+Reset), there also got a BLANK SCREEN (NO LCD Backlight).
5) TOUCH SCREEN detects TAPs & make sounds (Tick Tick), That indicates Touch Screen Working fine.
6) Qwerty KeyBoard Works fine. I don't know at what extent, since I can't see nothing on screen. But when I press a key on QWERTY Kbrd, it sounds Tick.
7) Transfered(Beamed) a CONTACT from my another XDA IIi & found Its accepted the beamed data.
8) Volume Up/Down make sounds (Tick, Tick...).
What I Did:
1) Removed the Battery & re-inserted & tried to BOOT it. NO result, just a WHITE SCREEN.
2) Purposely Tried to Rotate the Screen in Wrong Direction to test the loose contacts of co-axial cable.
3) Lastly Dis-Assembled the whole handset (Removed all parts 100%) & Re-Assembled it. But the Problem remains SAME.
4) Dis-Assembled again & this time I tested the LCD Co-Axial Cable's connectivity from MainBoard side connector to LCD Side Connector. There are 2 Cables which connects to LCD. One is 30 Cores Cable & Second one is 40 Cores Cable.
I Successfully tested 30 Cores Cable(Actually it used only 28cores cable, remaining 2 points at connector are DUMMY) & Second 40 Cores Cable I'm UNABLE to Test Since I lost my patience while connecting my Testing Meter to Hair Line sized cores & in just an 10mm connector got 40 cores!!!
5) Observed all cores which passes through SCREEN ROTATOR BASE Hinges & found there is NO physical Damage or CORE CUT.
CAN ANYONE HELP ME TO SOLVE THIS WHITE SCREEN PROBLEM?
IS IT A HARDWARE BASED PROBLEM? OR SOFTWARE BASED?
IS IT A PROBLEM WITH DISPLAY CHIP(IC) ON MAINBOARD?
JUST CONFUSED & SEEKING HELP FROM TECH GURUS.
THANKS IN ADVANCE.

This seems to be a hardware problem. Check connectors in the display housing first. This unit is quite easy to disassemble.
Before you start, you should have a look in the universal SERVICE MANUAL to check out how it gets torn apart .
If all connectors to the display are right in place, but your display still shows nothing ...open the universal body too.
Folow the steps in the manual

White Screen
Hello, this is my first post. May I first just say how great I think this site is, the guides on here really are useful to beginners.
With regard to the white screen, not sure if this helps, but during dismantling of my various PDAs, I managed to connect an LCD ribbon incorrectly, I kind of forced it in & folded one contact over, resulting in white screen. Disconnected, straightened & refit. Hey presto, works like a charm. Hope this helps.
I had the issue, had to buy a new flat cable
It is rare to actually see the damage to the cable, because the damage is inside the insulation....
Best regards!
On the topic...
Hello!
I have a similar issue with my Orange SPVm5000, except that mine will work for up to a minute after a hard reset before going to a white screen.
If I hard reset pressing the left+right+reset keys, the device shows the boot screen and sometimes ever goies into the initial setup but then all of a sudden it goes white. I've opened up the screen and verified and reconected all connections but still the problem persists. Also I've noticed that its not any action I make that causes it; more like a heat/timing issue. Per advice above, I will check the connections in the body but does anyone have any other ideas?!?
Thanks!
Greg.
I have a similar problem. The story;
I purchased an orange branded M5000 on flebay described as second hand in fantastic condition blaa blaa.
When the phone eventualy turned up it had no manual, the outer sleeve of the box was missing and the wrong usb cable was supplyed (one of those larger usb plugs you usualy get for printers.
I have shedlooads of cables and rely wasn't bothered about any of these problems at the time and went about charging the phone (it was totaly flat)
When fully charged I stuck my sim in and poweded her up the phone works fine in portrate and landscape view but as you rotate the screen so it is inline with the keyboard the screen fades to white about half way.
I contacted the seller who basicly told me the phone is second hand so sold as seen!?!?!?
I have flashed various roms on it to see if it was a software fault but nothing.
I think this phone had been in storage as its battery was totaly flat and incorrect accessories suggest the seller didn't check it before shipping. So I believe there is a problem with this phone that occurs when stored.
Sorry for the long post
Have you flashed any rom or just had this problem ...
my conclusions:
1. If you have flashed a new rom to your universal, try to reflash the original rom, it works for many users.
2. If you havent flashed any rom, maybe its a hardware problem.
2.1 If you just used it in a bad way, (ie: rotate screen in wrong way), dissamble it..
2.2 If you have let it on a heat, weat, etc.. place.. maybe the mainboard got a cut-circuit.
Saludos
I tryed a couple of popular WM6 roms (I forget whitch ones) and returned to the genuine Orange WM5 rom. So I doubt its a software fault.
As far was extreme conditions go the phone was well packaged when posted I will gove that to the seller SO unless the eposure happened before shipping I don't think thats to blame ether.
I think the wire in the swivle joint is failing and will continue to get worse as the joint is exercised.
Try to clear it up..

Sounds like the image could not be loaded completely.
The framebuffer is initialized correctly after cold boot, but afterwords booting into wince fails.
So maybe it's pure software issue (flash content is corupt -> image is broken).
Other possibility: Some region of your flash is damaged (more hardware related).

Looks to me like a typical cable issue. Maybe someone twisted the screen the wrong way!
So this is what i guess at least.

White screen
99 % of these white screen faults is a typical cable issue. And you don't have to twist your screen wrong way to have this problem, also.... just twist it too often First you have to see if the device is working, apart the screen.... call the number of your phone see if it is just screen related problem. Broken display cable will leave your device oprational, you just don't see the image.
I know it is "less painfull" for people to think it is a software problem.... (The "it would not happen to me" syndrome ) but sometimes things just brake, and moving parts are most risky...
The fact you don't see the damage is of no importance due to the size and nature of the damage. Don't expect to see broken wires in the cable. And even if you check the cable by you instrument, somethimes it will show you it's ok, but in some positions it will loose contact.
Try a different cable... that way you'll be sure.
Best regards, and all the luck!
"Looks to me like a typical cable issue. Maybe someone twisted the screen the wrong way!"
I agree and luckily, finally paypal do as well.
It is being boxed up to a red faced seller as we speak.
A happy ending for me (speaking to soon?)
i hav the same problem as u "HELLCRUSHER" and i flashed also but was not able to cure
still hav this white screen ..
Found this link for some where selling the screen cable assmebly.

Display problem - who can help

Hello everybody,
-3 weeks ago a had the first problem with my display: it was gone and when i tried to reset the screen was almost un-alignable. only after a lot of resets it worked again!
-now since yesterday my screen stopped working. All the other functions work like phone etc., but I only see the backlight of the screen and nothing else. I tried to reset, hard-reset and took the whole artemis apart. Only saw a little black spot on the displayconnector (can it overheat?!)
When trying to reset for a hundred times it worked three times! I was able to do a hard-reset with screen, but that's it.
-Another thing I notice is that when I try to charge my artemis it takes longer then normal for the orange charging-light to light-up. Also after 10-15 seconds it starts to blink in stead of constant-lighting-up.
I'm running Artemis touch 4.02 with battery status on 201 mhz (was running 247 mhz until hard reset yesterday). Radiorom: 3.21.90. Accesoires: sandisk 8gb sdhc.
Who can help??? Will fitting a new display do the job?
What a coincidence, my screen also stopped functioning yesterday for several hours and I was forced to use mouse mode, until it just started working again but needed to be aligned several times over 20mins of use.
Today, same problem. It comes and goes, needs constant realigning...
I'll be doing some surgery again when I get home tomorrow, dunno about black spots yet.
I've just replaced the digitizer on it and I suspect a contact has come loose on the back of the LCD (I hope!).
Anybody else have any ideas?
so you think it's a problem of the display, rather then the main board or something like that? because I don't get a view on the display at all, only backlight.
I'm doubting on buying a new screen for about 40 US dollar. Would be sore if that didn't solve the problem.
p.s. took the artemis apart again yesterday: saw a minor damage on the display's connector. If that can cause all this, then a new screen would be the solution I think. But how does the connector get damaged???
FIXED
bought new screen. problem fixed.
Did you buy just the digitizer or the whole screen?
I think by buying the cheapest digitizer I could find is where I went wrong, looks like I'm shopping for another one...

Humming sound from display - normal?

@all,
been using p3300 for ages now and never noticed it before - there is a humming sound coming from the lcd, increases slightly when touched. (admittedly, your ear has to be straight in front of the lcd )
now, is that normal?
is that due to the rom used, or
is that due due to a defect resulting from ...?
or am i just getting oversensitive in my old days?
greetz
mines been doing that for ages now, and until you mentioned it again id grown completely used to it, now its all i hear.....cheers!
just joking mate, mine increases when i underclock it so perhaps is something to do with that as well, or some power regulation
Do you have your PDA overclocked?
That can be a "secondary" efect of it...
Cheers

Do I consign my XDA IIs to the bin or persevere?

I am aware that the problem with my XDA IIs is similar to other malfunctions described within this forum, however often those posts appear to be left unanswered. In order not to incur the wrath of the administrator therefore, I seek clarification and therefore I consider that I'm not duplicating any prior posts.
I acquired an XDA IIs from my son last year - the screen was cracked, the device wouldn't turn on and there was no charging cradle or lead. About six months ago I bought a usb sync/charging cable and a screen from mobilefun (described as "new" but wasn't - I complained but couldn't be ar**d to return the thing) and this week purchased a replacement battery from ebay. Now before you all shout 'caveat emptor' I wanted to do this as cheaply as possible.
I duly plugged the thing into my laptop anticipating joy and smug satisfaction; unfortunately I have only encountered misery.
The device pings, the amber led and the backlight for the screen come on (although there is nothing evident on the screen - did I pay 30 quid for a cumbersome torch) and everything looks rosy for approximately 10 minutes. Then the led turns red, the backlight switches off and it remains dormant for about 10 minutes. This cycle continues ad nauseum.
I have active sync and when the xda is in amber mode I can "see" the device on my laptop and I can communicate (synchronise) with it. So what is the problem(s)? Is the new battery a dud and a salutary lesson in why we get what we pay for? Should I be concerned that the screen lights up but displays nothing and therefore regret not returning the screen to mobile fun? Is the internal battery OK - if I change it will it have an impact upon my charging tribulations?
I hope that you can appreciate that I am loathe to spend any more money on this thing but having made an investment I'm also reluctant to bin it. Help the noob oh great ones.
first of all, welcome to the forum
interesting things happening there.
from the distance my first spontaneous reaction was "the battery and the display must be broken", which, after 3 times reading your post didn't really change despite the gigantic coincidence.
what you can try first of all is: install MyMobiler to your pc, which uses the activesync connection to connect remotely to the device and gives out the screen on the pc screen, where you can control your device with keyboard and mouse. that is always a good start, in case the display does not work or has no touch function any more...
http://mymobiler.com/
if that works out for you and you can see the screen, you can say for certain, that the device's screen is not really ok. the next thing to test would be the digitizer then.
you didn't write, whether you bought a complete display bundle or just the real screen, so let's test the touch function. i case you had seen a proper screen with mymobiler, try tapping and tapping and holding with the actual stylus on the actual screen while cradled and look at the screen's reaction in mymobiler, if the touch function works, you should be able to control the device, which would probably mean "get a new screen, digitizer is fine".
about the battery: since you don't really know what state the phone is in and how good the battery actually is, you should try and take out the battery connect the external power source to the cradle and load the battery in the back of the cradle. you know my device with wi-fi on for instance consumes more power, than can be loaded via usb, so after a little while, though connected to power with the amber led lighting up, the device will turn off. not with a red flash like described by you, but still...
if you load the battery to the max in the back of the cradle, take it out for say, half an hour and jam it back in, the orange led should turn green again in less than a minute, since no power was consumed, if that works out, you can then put the battery back in the device and then cradle it normally and see, whether it turns off again after 10 minutes.
the point is, all this does not really help you, i know that, but it can give you ideas on how to test the flaws and determine what really is wrong with the device. maybe you did not buy a broken screen and broken battery, maybe the device is so screwed, it destroys them itself. or maybe these testing methods give you a greater insight on what to test and maybe then you can confront the retailers responsible for that and prove it is their fault. i am sorry to hear about your device, without it working you are missing out on a great mobile experience.

Chef_Tony
Deep joy coupled with intense fury
Chef Tony - you are indeed a genius and I humbly bask in your glory. I've downloaded mymobiler and it displayed my screen which naturally needed to be aligned as I have put in a new screen and digitizer. It would appear that the digitizer is fine but the screen must be kaput.
I repeat that salutary lesson kids - if you purchase something described as new from a retailer and subsequently discover that it isn't, don't complain about it and then expect the Returns Elf to despatch the suspicious item back to the offending company. Do it yourself or bemoan the day that you couldn't be bothered to send it back to the company.
As for the battery I'm awaiting a different charger (I don't have a cradle only USB sync cable) but as I've mentioned previously I'm loathe to spend any more money so this might all be academic.
Thanks again
Buying from eBay is what 90% of ppl do here, it is not only a cheap way out, but the ONLY source for many replacement parts. Nothing wrong with that mate. eBay is actually also more expensive than numerous online wholesale sites for certain phone areas too.

Galaxy tab s 8.4 t-700 lcd screen issues

Hi, maybe someone have encouter similar issue and have and could comfirm if there could be anything else i could do except replacing whole lcd+touch, which cost pretty much same as new unit
My my screen is showing some weird artefacts on screen, at first there is not much but its getting worse after few muniutes of use. If i lock and unlock the device i show white light bleed on left side of the screen (first picture) then if i lock again, wait for a while it disappears, but some artefacts and color pixel start to show on left side (second pic). After a while some strong white lines apear, always in the some spot, but if i put down the device for few minutes it desappers. Reattaching battery didn't help, i guess thats not the case. Could this be a faulty LCD connector? Or the screen is dying.. ? Definitly not a software bug, i just upgraded to 6.0 and even in bootloader mode while upgrading there were those two lines (last pic)
What screen brightNess do you use. It's recommended to use 20% to avoid screen burn in

Hmm.. since i usually use the tablet in bright locations its probably set to higher then 50%, at least..
There is one more thing, after like 10 minutes of use, almost all the above issues stops, only thing that stays is the "burned like" vertical stripes, barely visible, on about 2/3 of the screen.
I does not make the table unusable but its quite annoying...
could this be affect of screen burn in ?
i think its just a bad screen from a begining cuz i have tab s 8.4 for almost 2 years now and i gave it to my brother for a year and he was in Tenerife...temperatures there are high so i doubt its a screen burn since my tablet is still ok even after one year at Tenerife with probably brightnes always on 100%...just sharing my xperiance cheers guys
