Problem with trackball!

Hi guys,
The trackball on my Orbit has stopped recognising being rolled up, left or right, and the silver clickwheel is stiff. Is this repairable myself, or should I be looking at a new motherboard?
Cheers,
Nick

hey dontpannic, don't panic
at least not too hard.
It is possible to exchange the trackball unit. You can sell a new one on the internet (I bought one via eBay, it was in your country and very cheap) Allthough, it is kind of hard to get the old unit out of your phone. You will have to totally apart your phone, because the trackball unit is stick to the daughterboard which is behind the LCD
There are a number of guides to help you apart your phone, you can find it somewhere on this forum. Once apart, you can blow the dust out and uncover your current trackball (mine was kind of hidden ) Or you can get the whole trackball off the board and replace it.
(I should note I got my phone apart couple of times, so have some experience. It can be tricky)
ciao!

I agree with amfasis, it can be tricky but gets very easy once you've done it a couple of times and know what to expect (how much force to apply separating parts...)
Everything on the daughterboard is pretty open under the cover so I suspect something sticky got dripped in there (cola?) from the symptoms you mention.
I thought I had a problem with my daughterboard as well since I was getting random scrolling action in all applications, but it turned out I had some dirt stuck on the side of the screen giving a bad signal on the touchscreen.
I took apart my whole trackball and even took the silver cover off the silver scroll wheel toggle and took out the tiny spring... that was an adventure getting it all back together correctly after cleaning!
I chalk all of it up to an excellent learning experience and now have no fear of taking it all apart just to look at it again. You will too.
Good luck!

Thanks guys! Will give this a try and see what happens

wobbly screen?

Ok, now when I tilt the screen of my touch pro2 up, it has a slight wobble (in the direction the screen tilts, not sideways). Is it normal for a tilt screen device to have this "freeplay" from new?

Hi All
I have the same problem. My screen wobbles too. min 5-7mm "freeplay".

See my post yesterday
http://forum.xda-developers.com/showthread.php?t=524432
Just had blokey on from the company saying it was normal for the TP2. I must have had a good 4-5mm of play when it was tilted which seemed odd as my Kaiser was (and still is) totally solid with no play at tilt.
It would be really useful if people could post to say whether they have any 'freeplay' or not when tilted.
Thanks
John

yes freeplay here about 10m i would say its very loose

even 10mm is super loose
i think becoz it use different mechanism.

Have logged a call with HTC supprt to get the definitive answer, to wobble or not to wobble. Will update this post when I get a reply

Sent my unit back today and hope to get a replacement soon.
There was something seriously wrong with my unit.

tiinking of sending mine back to be replaced not only does it wobble in tilt but with the keyboard closed if i holed the phone flat of my hand and put slight pressure on the top left corner the screen slide about up just on one side is this normel so the screen can look off set

mine is loose but that is normal as you can't have the screen too rigid in tilt position. also its on hinges and that will have a part to play with the wobble. remember the screen is attached to the body by a ribbon which needs the screen to have that bit of play to take tension off the ribbon. when in tilt position look at the back of screen you will see the black ribbon. wobble the screen and you will see the kink in the ribbon when wobbling. now imagine having a really taut screen and the pressure that would be exerted on that ribbon. wobble is acceptable as it plays an important role! thats my opinion. i have a kaiser/tytn 2 and the screen is very wobbly and loose.

I second that Shingers,
My Kaiser became very loose after about one year.
The Rhodium looks to have a much more robust design though and yes there should be some amount of free play.
Time will tell how good the redisgn of the tilt mechanism is though.

Beasty

My Hermes has the same wobble since the first time I got it. 2,5 years later, it's still working great. Don't think it's a lot to worry about. or the people who don't have the wobble, it probably will be there in time.

yeah yours defo looks like one of the hinges are loose. that needs to go back defo. might just need tightening but i'd request a replacement if i were you! good luck with that

thanks for the input guys,
John, let us know what's the official position on this. Apart from the wobble device is working fine so I decided to keep it, it's not a deal breaker for me - i operate it while flat anyway and it stays tilted when put on the desk.
The looseness is like, when you tilt it and shake back and forward slowly, it eventually goes down in 3 shakes. Using the touchscreen when tilted is impossible unless you have a finger behind it.
I don't know, all the reviews are praising the stiff tilting mechanism of TP2 and online videos show people applying a bit of pressure on the device to tilt the screen, mine is not like that, that's why I started the thread.
It did say it's the first batch here in UK on the MFDirect website, so could be an early flawed version.

Will do, still waiting to hear. Just think its a bit disapointing if this is a part of the design as (and I really don't want to take anything away from the brilliance of everything else about the phone & how much people, including me seem to love it) it makes it feel, well cheap.....which as you say was the opposite of the reviews the phone has got from everywhere else.
Maybe mine was a lot looser than others have experienced? maybe I'm just a fussy ba***rd, don't know?
MPD won't replace it as they say it is normal, I'm waiting for it to come back then I'll send another email with a couple of snaps/video to HTC to get the definitive view. Will keep you up to date.

And waht about this,it was a little hard for me to explain it corrctly,so i'v take a picture
is it normale ?
http://img38.imageshack.us/img38/4057/tp2a.jpg

yes i think it is. Its the part that slide's out and also can be tilted. That means that it isn't attached to the bottom of the device and i guess that is wat causes the problem. I also have that problem a bit.
When i slide the device out and NOT tilt it it looks perfectly straight, but when i tilt the screen it wobble's a bit but i guess thats normal to..

same problem ..... same wobble .... still i love it

Thanks guys so i will love more my tp2

The definitive view part 1
Hi all
HTC have replied to my first query. Posted below. Basically there should be no looseness/wobble. I'll speak to them and MPDirect and see what happens next.
'Thank you so much for contacting HTC Technical Support Team.
Regarding your request, kindly note that the symptom you stated (the screen when tilted was loose on its hinges and wobbled back and forth by a few milimetres ) is not a normal symptom. the Screen should be firmly in place.
For further assistance please don't hesitate to contact us on our hotline < 0845 890 0079 > or visit our website at www.htc.com .
Respects & Regards,
HTC Technical Support Team.

Tilt 2 owners, do you guys get this?

ok soo i dropped my Tilt 2 from a standing point (which is about 5 and a half feet since im 5'9) with the phones keyboard open and screens tilted, whats funny is that no battery fell out or anything, it just shuts off, i had to turn it back on.
when i shaked the phone i heard a slight rattle and i reckon its from the Flex Cable from the LCD screen, the rattle stops when i have my Tilt 2s keyboard open, but when i tilt the screen i can hear it slightly...is that normal?
also what is going to aggravate me for the rest of the time im going to own this phone is that when im using the phone's software keyboard on portrait at say like a 15 degree angle i can hear taps which is quite annoying but if i hold it at a 45 degree angle it stops, i turned the phone to the side i notice a gap, not a big one and not really noticeable but id say its roughly .5mm thick, i push the screen down and the gap gets smaller, is normal as well?
plz let me know thnx a lot

short answer.... no.... not normal. You knocked something loose inside hence the rattle, WHICH you probably already knew The gap, also not normal. Well wait.. I should correct myself. This is all probably totally normal for people who have dropped their phone. You're lucky you didn't crack your screen or do more damage and the phone's still usable!

hmm, well i talked to one Tilt 2 owner and he said he has that rattle and he hasnt dropped it? but like i mentioned, the rattle must be coming from that Flex cable that goes between the motherboard and the LCD screen....

No rattle and no gap on mine, but I've only had it 5 days. Give me time.

I have rattle too, but i think its the G-Sensor !

i did a couple of searches on PPC and some say its a normal thing especially in the tilted position? http://forum.ppcgeeks.com/showthread.php?t=87452 at least im not the only one! i just have OCD xD
heres a video of the screen problem im having
but its not as worse as his but you guys get the point

I just dropped my phone yesterday with keyboard out and tilted and I got a similar problem to this. My screen only has a gap when I pull it up, which I wasn't able to do before, but the screen slide is now about 1 or 2 cm's to the left causing it not to line up with the keyboard slide. Somewhat aggravating, but totally unnoticable unless your holding the phone. I don't get any rattle though...

well if i were to dismantle the phone and repair the little bridge that goes across the back of the LCD screen would that solve the issue? because it seems when i push on it it seems to fill a gap but idk if thats what causing the whole screen and kb issue but im going to do it when i have the chance

I have a tilt and mines exacly like the one in the video with the vary small gap and the screen wobble, I always assumed it was normal, mine dosent rattle though

that little gap and the screen wobble.
it just because is got movable parts, look at the screen hinges if i can call them that.
its the reason i didnt want to get mine, ive always chose candy bar phones so i dont worry about that.
but i did get me a tilt 2 and have dropped it too, i also think my wobbly screen started after i dropped it, but ive had it a year, since it first came out. the only thing i hate reall bad about this phone it the lack of a headphone jack I HATE THAT WITH A PASSION.

[Q] Touch Pro 2 stuck in Landscape

Hello,
I dropped my Touch Pro 2 in fresh water. No insurance of course and no more discount from T-mobile to buy a new phone.
Following video instructions on youtube I disassembled it, I believe without breaking anything.
The LCD screen was gone (water inside), and I bought a new one in eBay.
Once I received it I reassambled the phone. Evertyhting seems to work fine but... the screen is stuck in landscape!
Of course I did soft and hard reset, tried to play / disable the G-sensor and orientation sensor, nothing: I believe it has to do with some switch that recognize when the keyboard is slide open, but I have no idea what sensor is it, I can't find any mechanism that resemble a micro switch or a mini magnet related to the opening / closing of the keyboard. Instead I find a microswitch that senses when the pen is inside, but nothing about the screen.
Any suggestion, does anybody here have any hardware knowledge on this topic? I tried to use software like Gyrator 2 which put a patch on the problem, but I would rather fix the hardware first: perhaps I did not mount something correctly, where is this sensor, is it magnetic or microswitch, I can't see anything even with lenses on.
thank you all in advance
....

I have exactly same problem, my TP2 is stuck in landscape mode. I bought TP2 in the US. My housing was broken so I bought a new one in europe the oem one with lcd screen and digitizer... Could this make the problem?
I am pretty sad, I dont want to buy a new phone :S

The sensor must be in the screen-half of the phone underneath where the red "end call" button is. This is demonstrated if a healthy phone is slid open, and then you pass a small magnet underneath the screen in that area, screen will flip between portrait and landscape.

Which yes I did the same thing today and it was your post randell that helped me. All you need to do is go to walmart purchase the smallest but most powerful smallest magnet you can find. cut you a piece of it, superglue it to the bottom right corner. worked like a charm.
or if you wanted to open your case back up like i did you can superglue it on the inside lol. If you look at your old case you will find your old magnet you can use. simple easy just thought id let you know k bye ta ta.

I was on here by chance and I had the same issue when I replaced my digitizer on my TP2 a year ago. I could never figure it out so I bit bullet and brought a new phone. I will try this when I get home and if it works be great because i loved that phone soo much when I had it thanks guys!!

[Q] Strange phone unlocking

Hi,
Please forgive my language mistakes.
I've got a strange issue. When I push my cell with my thumb in the 'red' area while holding blue one in place phone is unlocking automatically.
I've dissassembled and assembled my phone twice without any problems but it might be a consequence of that.
How can I disable:
1) automatically unlocking by removing stylus (maybe I'm pushing some sensor?)
2) automatically unlocking by sliding keyboard (maybe telephone thinks that keyboard is opening? - despite that that keyboard opens in opposite way....)
Thanks in advance

1&2 are effects of software. I think they can both be disabled, probably deep in WinMo's registry... I'm sorry, I don't know how to disable either of these off-hand - but I'm sure there's a way in WinMo.
As for your first description and picture, I have no clue what to make of it, sorry. It appears your phone is badly cracked, and the phone is thinking the keyboard is opening as a result of pressure on that cracked section.

Well I also believie that these options can be disabled by WinMo registry editting. The problem is I don't know where to modify.
Does someone else knows?
Well my phone is quite old but it costed me a lot of money so despite it's quite cracked I want to use it!

Maybe try using TouchLockPro to control these sensors:

Thanks. It only helped that right now i know that this is caused by keyboard sensor. In some strange way the phone (when i push as shown on picture) thinks that I'm opening the keyboard (must be really 'cracked' becuse the keyboards opens in opposite direction).
What's sad - the TouchLockPro is unable to control this behaviour. I don't know why - maybe because of Energy ROM which has CHT inside and this is overwritten.
Any ideas?

In the back of the Midframe (the metal back of the top half of the phone where the screen is at) there are two small metal sensors or whatever you want to call them. They are inside the track of the slider, try adjusting those a little and see if that makes any difference. I think that those could be the sensors that are messing up the keybaord detection on your phone. Maybe when you apply a little pressure on the phone the sliders inside the track are moving a little causing the phone to think that you have slid the keybaord open.

Thanks for your reply. Are you talking about these on below photos?
And if you're talking about these ... How do they work? Because if I will slide out the keyboard a liitle (the metal sensors are already untouched) the keyboard is still not lighted and a screen is in portrait mode....

I'm sorry, I missspoke. After further investigation it looks like the sensor is magnetic. While your keyboard is open try to place a magnet under the screen part of the phone and see if that would flip the phone back to portrait mode. Try to move it around a little to find teh most effective place for it. If it does we might be able to solve your problem with a little improvisation.

Thanks for your reply. This is magnetic indeed. When I will place a magnet under screen part (1/4 of screen part area under the buttons) it switches to portrait. But I can't a "pattern". I.e. if i will place it under right bottom (if you're looking at LCD) corner it switches to portrait but if I will put for a while magnet onto middle of 'screen-part' (ofcourse nothing happens) and then back again to 'right bottom corrner' also nothing happens. Unable to find some pattern/rule for that.

Good. So here is what I think is happening with your phone. When you press the part you were talking about in your first post, the magnetic field from the bottom of the phone is getting distorted for some reason making the upper part of your phone think that you have slid the phone open thus unlocking it and switching it to landscape mode. We do not want to buy anything costly to fix your problem, so here is what we can do. We can strengthen the magnetic field by placing a small 2mm magnet somewhre on the lower part of the phone preferably insulated and glued inside in an empty space. What will happen is when your keboard is not slid open the magnet will give teh signal to the upper part and it will be strong enough that even if you push it like you were doing it will not unlock. But when you slide the keyboard out the magnet will not be under the upper part anymore so the uper part of the phone will not be affected by it. Since you already opened your phone twice I don't think that it should be a problem for you. Just be carefull because we don't want the magnet to become loose and move around and short anything.

Thank you for your reply and appreciate your help! I've quoted the most interesting part. I had a scientific lessons on school and was moving my magnet around this 'magic corner'. I want to confirm that somehow i might have strenghed the magnet inside the device? Because right now it's a little bit better (at least better that I don't want to push with more power in case of destroying it).
Another question is about 2mm. You mean a cube 2x2x2mm or 2mmxYxZ (2mm thickness required.

That's interesting, maybe you realligned the magnetic field, that is not entirely impossible. I was talking about diameter, we want a very small magnet. It looks like the 2mm is more expensive than 3mm so maybe you can use a 3mm like this: http://www.ebay.com/itm/50-Disc-Rar...598?pt=LH_DefaultDomain_0&hash=item3f0a038d56
But since it is better now, you might not need it.
