High Pitched Noise when Backlight is on - MDA III, XDA III, PDA2k, 9090 General

Hello everyone
When I switch on my MDA III (backlight ON) it emits a high pitched noise which makes it uncomfortable to use - has anyone else experienced this? I have had it repaired 3 times with this same fault and it come back fine but after a few days use the sound reappears - Anyone else got this and is there a fix?
Cheers

Hi there,
Ive got this prob too.
So has virtually everyother Blue Angel owner I know
Its the backlight tube which causes the sounds, very annoying for the first few secs when on the phone!

It isn't a 'tube' creating the blueangel backlight, as it is in the earlier Wallaby and iPaq 3XXX series, it's low voltage LED's using a transmission layer of plastic. No inversion needed and not the cause of the buzzing sound :-(

Updated (09/05) POLLING - High Pitch Noise O2 Orbit

I have noticed that my orbit is giving off a very high pitched noise, which is almost undetectable, does everyones buzz, squeal, it is hard to explain but is an electrical noise of some sort which is only present when the screen is on?
Any suggestions, or is this a "feature"
Hi StewD,
I get a kind of ticking from my speaker and as you say maybe a 10khz sine from my screen.
I believe that this is simply an electrical effect common to all such lcds but I can only chop wood so maybe someone with a greater range of abilities can tell me I am right.
I know what you mean, I have an Archos and many other "toys" with screens, PSP, NDS, Car DVD player that have an LCD screens which are silent?
while my o2 xda is ok, a friend of mine had a similar problem (the sound would only appear when the screen is on), got it changed by o2, new one is dead silent.
Do you have any more details, that is sounding the same as mine!....Can you get him to contact me....please.
High piched noise on Orbit
If your describing a high piched sound worse when you hold the styus on nthe screen I have the same. Just got my old XDA IIi out of its dust sheet and it has the same but higher!!
That's it exactly
Is everyone affected by this "feature"
Please reply with yes or no below.
I have an Orbit, and don't have any high pitch sound.
Tried with and without stylus.....silent.
Thanks Patrick, that's great, I'm hoping your in the majority to be honest as the sound when I'm on a call is almost unbearable, what I'm hoping is that I will get a couple of dozen or so silent orbits, from other forum members which I can then go to O2 with and get it replaced....
I believe it is a characteristic of the screens. Is it possible that some peoples high frequency hearing is not quite as sensitive as that of others?

I know what you mean, but when I'm on a call it is intolerable, well almost. But like all these things unless you get 2 or 3 together at the same time and try them I'll never know?
Pity this forum doesn't require location when registering, not many people have updated their profile with where they are?.
Well that question received a lot of interest?! Is there anyone out there??
Hi StewD,
I am out here, off work while mrs. is in Austria.
Just a thought, but do you have very large pointy ears?
I usually just press the power button when I offer the phone to my ear, screen off.
LOL no standard human ears I'm afraid.
That is what I'm doing at the mo. but if there are silent orbits does that mean there is something wrong with mine??
I just thought there would have been a lot more in the way of replies to this thread...?
Thanks for your reply
I had the same "feature" in my Orbit. It was fixed by O2 Germany. So far (two days after coming back from service) my device is silent.
Cool, that's the sort of thing I wanted to hear, did they explain what was done, New screen, new firmware, or is it a new handset?
I can hear a high pitched whine from the LCD when I hold my phone to my ear, but it doesn't bother me too badly. I suspect it may be too high pitched for some people to hear (like the noise some TVs make or some dodgy fluorescent lights make).
However, thanks for the tip about hitting the 'off' button once the call is in progress!
[QUOTEHowever, thanks for the tip about hitting the 'off' button once the call is in progress!
[/QUOTE]
It took me about 18 months to figure that out!
Well...contacted O2 today, and after the usual 15 minute wait for an operator person, explained the problem and she agreed that the handset was faulty and I should send it back for replacement.
Now I'm going to be without "My Precious" for at least 3-5 working days........Arghh.. I was just getting so attached to it as well....?
I will post more news when my replacement arrives........thanks for your replies.......

Strange whistle all the time

Dear,
I have a problem, and I'm not sure if it's possible to fix. I have a X01HT that I flashed many times. From some days ago (I think), it produces a really annoying "whistle" (like a 'piiiiii') that destroyed my ears . I thought that it was a problem of any program, so I try to hard-reset, and also Flash another ROM (even another Radio), but nothing changes. Even after a Hard-reset, the sound never disappear (><) Any idea?
Thanks
César
Is the whistle on in bootloader? In standby?
Have you checked using loud speaker and same noise?
Have you tried muting the volume?what happens?

It is all the time the device is ON: since I press the button and it turns ON until It turns OFF, no matter what it's doing: (rebooting, in bootloader after hard reset, with IExplore, etc.).

Mute the volume is the same; the noise is there.
Also, I notice that I can hear the noise real more stronger when I have the screen in front of me (If I'm looking to the back of the device, I almost can't hear anything).

Then it's just the phone speaker, not the loudspeaker at the back.
I would ask what happens to the noise when you plug in the headphones, but it's a hardware problem anyway, so repair center it is.
We use some Symbol PPT8800 series PocketPC devices (runs PPC2003) and some of our units start making those noises, after heavy use. But generally its shortly before they go pop, I'm afraid to say.
Hope yours is something else.

I plug the headphones, and it's the same.
I also imagine that it's hardware problem (><)
I had the same problem (AT&T Branded 8525) started after I'd had it only 3-4 Months. I'd purchased two and flashed them with same ROM's however, I only had this problem out one. Spoke to AT&T's division of HTC warranty center. End result...it was hardwar problem. They shipped a replacement device @ not cost to me. Problem fixed.
so as far as i can see there is no home made solution for this?
try removing the battery and try and turn on the phone without the battery (it won't go on) for about 10sec this will drain any remaining power in the circuits. Then reinstall the battery and see if that fixes it.
Chris
It sounds like you are having the same problem I have with my 8525. It's probably not your speakers but more your LCD screen.
There have been a lot of complaints about this, with no easy fix other than to send it in and get it repaired/replaced and alot of the times the replacements have the same problem.
I've learned to live with it by turning off the screen when I am on the phone.
backlight inverter..

That sounds right...so is there anything that we can do about it without sending it in for "repair"?

High Pitched Sound coming from Screen?

Hi guys! any idea what this is?? this morning my faithful hermes started making a high pitched noise, loud enuff to hear only when i put it to my ear. if i turn sound down or off it still emits, yet if i turn screen off it stops? what is this?? Can it be fixed? is this the excuse ive been looking for to upgrade?
I would also like to know the answe rto this, Is it normal? The same thing happens to me, I bought my hermes used and thought it was normal because of the LCD screen but sounds like I may be wrong.
This is wierd....there is one more thread on this one...
http://forum.xda-developers.com/showthread.php?t=357107
I have had lots of similar electronics like palm pilots and such that have done it so I just thought it was normal. I just hope when I get my WM7 phone next year it has an OLED screen so I dont have to worry about it.
This is not normal. I went through 3 of the m3100 devices under warranty with Orange before getting one that did not do this. Phones would be fine for a few weeks and then would randomly start this. Just so annoying.

AudioPara

Hi there!
I have tried to replace audiopara3.csv file from twaeks on TP2 thread and it did not do any good on my T-Mobile Touch Pro 2. Any ideas, please? Pretty please?
Earpiece volume is terribly low when making calls.
i tried the same and nothing happened either. in fact, my keyboard backlight switches on and off whenever it wants to now. idk if that was from the AudioPara issue or something else, but it bothers me a little. :/. Can anyone clear the instructions up?
for me the ear piece spaeker was unbearably low, then i foudn out the plastic cover piece that came with the phone was covering it, but eventually even with it off,
i used that audio cab thingie, and amazingly it worked for me
the volumes at highest are acutally very high, i actually had to turn it down 1 notice on volume, which is pretty good at least i can toggle it when at a busy area
dont know what to say for you guys but it worked for my tmobile tp2

Weird NOISE/crackling during call - DESIRE HD - HELPPP

Hello , i recently bought the Desire HD, and havent been experiencing any problems with it except of one quite annoying.
When im in a call, either outgoing or incoming, the speaker makes a weird crackling noise.
This happens always, and happens on both the phones speaker, and loud speaker (depending on which is selected during call), and headphones(when connected). Ive searched the forum, and some people have been experiencing a sort of problem, but not on the same device.
any help is very much appreciated thank you
I can verify that I'm experiencing the same with my Desire HD.
We discussed this issue already in the german "Android-Hilfe"-Forum. This buzzing, crackling noise seems to affect a small number of desire HD's. Mine was affected too. All the devices have been changed on warranty with no costs for the customer in germany. No matter from which provider they were bought.
Edit: BTW: Wrong Forum, I think. Could an Admin move this thread please?
Thanks for the quick replies guys, appreciate it
Hi All,
My Desire HD has started doing this today too! Really gutted. What has HTC UK support been like this on it? Replacement or repair, and how quick? I dont want to be without a phone long! Is this a widely recognised problem, apart from this thread I dont see much on it. Im wondering if the buzz comes from a loose LED flash cover vibrating caused by the speaker?
Thanks very much
I have the same and I thought it is the proximity sensor opening and closing.
Are you guys sending it back for replacement or are you going to live with it?
i have the same problem it sounds like the earpice is short circuiting for 1/10 second
i dont know is it a general problem or only limitted to our handsets
and if we update the radio version is it going to disappear or not
any help is appreciated

I sent 2 support cases to HTC at the same time. The one was for tjis issue and the other for something else. The other one was answered next day but for that one, not a word. Does this tell you something?
didnt understand you sir.

I say that: I contacted HTC support in regards to this but haven't received a reply. But, I have received replys for other cases. And this doesn't sound good.
i have the same issue
Issue with noise
I recently replaced my DHD due to a similar issue. I found if my hand palm was making contact at all with the SIM.SD Card cover, ie the antenna I would get an extremely high pitch feedback sound. Also if phone was on charge the crackle sound was audible.
Orange were great and replaced the original handset straight away at no cost but the replacement also appears to have the same issue. For the moment I'm considering contacting HTC direct but i'm not sure as otherwise I love the phone, and truly believe it is the best on the market.
I think the issue might be resolved if i get a outer protective cover so I'm going to try that first, and not use the device while on charge.
Would be good to know if others have had these experiences.

Whatever you decide, contact HTC so that they know and work on the problem. As I said, I contacted them but never received a reply which means that they are aware and have no solution.

That must be a different issue. I hear that noise via BT headset when I don't even touch the phone. I believe it's due to the sound frequency change during a call and the low quality speaker cannot handle. It's like using a high wattage amplifier on a low quality speaker and expect to hear deep bass sound. I guess you all know the result of such sound.
I'm also experiencing this problem. Sent the phone in and got it back but the problem is still there. They changed the motherboard and the loudspeaker but that obviously didn't fix the problem. So now I probably have to send it back again.
i just hope this problem can be fixed with software..
hi all,
in my case occasionally during call's even whit sound volume low a ear the person talking with " extremely high pitch feedback sound".
It's a very good phone but that problem is starting to annoying me.
i allready send a email to htc portugal and their response was to send the equipment to the repair center
in you opion what should i do? send to repair?
Thanks
Have you tried enabling the SRS improvement? It can be done in the music player. It made the crackling sound during calls in my device disappear...

I will try this and post back...
What I'm experiencing, when I'm on hold with my service provider (Vodafone AU) I can hear the normal on hold music then at random intervals just for a half a second or so the music cuts and there's an annoying crackle noise. Sometimes there is no noise for a while then there can all of a sudden there can that crackle noise every few seconds. Like another person has said for me if I change to loudspeaker it still does the crackle noises and turning the volume down doesn't help. I've tried taking my hand off the phone but it still happens. I have noticed a few times the reception bars icon, drop a bar or gain a bar when this noise happens so maybe there's a link?!? By the way I'm running LeeDroid 1.4.1 (wich is based on HTC's 1.72.405.3 ROM). Also I'm running the Jan 17th Radio version: 12.39.60.19U_26.06.04.06_M.
Right. This could well sound daft but try it anyway! Someone on another forum said it worked for him (her?) and it worked for me with a Nokia E71. The speaker was 'crackling' so I did the usual googling. The answer was, for me, to suck really hard on the speaker a couple of times. Basically the diaphragm gets put out of place and the 'sucking' gets it back.
Try it and see! Though it won't fix the 'feedback-type' noises I'd guess but I find most of those are specific to a particular call. Either call back, or get them to call you back, and all is well.
HTH
