crazy trackball - G1 General

Hi
I am sorry for my english but i will do my best to write well.
I have some problems with my G1 Trackball, i hope to find a solution, even if i am obligated to déactivate it, when i touch the trackball, the phone become crazy and starts a search with repeated letters and numbers like "2u542i33333333333" and continue to repeat the number 3, when it happens, i can't stop it or cancel, even all buttons become useless because the phone i think!, becomes busy. plz help me i love my G1 but cant use it well with this problem, somtimes i can't respond to a call because of this.
Thank you

Seeing as you just registered: are you even rooted? If you're not rooted just take it back and get a replacement.

Hi g13013!
I had the same issue on my device and was able to fix it.
It was caused by some damaged component on the mainboard.
Please follow this thread for details:

I read that, good job. However, if he's not going to root ever, he should try to replace it first. No need in messing up a warranty unless you're going to root. And taking it apart REALLY voids your warranty.

Sure, i totally agree...
In fact, swapping some components on Dream's mainboard is for geeks only
If you got no clue about all that stuff, you may also brick the board forever.
Better claim warranty if there's one.

thank you all,
First of all i confirm that a bought it by internet and there is no waranty, so i will try the solution you gave me.

HI scholbert
(plz dont tell me that is a hardware related, or a least tell me that is easy to fix)
I saw your solution and , doesn't understand all things because a have no experience in electronics, because I leave in Algeria, we dont have an HTC after sales service, so i will ask you if the spare parts are difficult to find, is the solution difficult to do, and it will be great if you can send me the steps by image.
thank you, even if you can't help me

Bad news...

O.K. let me point it out like this...
1. I only can tell you what i examined on my device, but your device exactely got the same symptomes... in other words it's the same bad behaviour. Also the sequence of "bad" strings are the same.
It's about 99% that's this is hardware related.
2. If you're in luck there could be a short circuit at the component itself. This would mean you'll have to find the shorted pin.
There's some hope that the component itself is not damaged.
3. If it's necessary to swap the component, i must admit this is no easy task. To make it successful you'll definitely need some special equipment (e.g. hot air gun).
4. The component itself is not easy to find/buy at the market. I took another damaged mainboard and unsoldered the part.
So to sum up, without any knowledge about all that stuff and without good equipment, forget about it.
There's only one thing you could do (no soldering but technical skill is required though):
Follow the service manual (link is in the wiki), disassemble your phone with care and remove the trackball mechanic itself.
This will prevent the magnetic sensor of the trackball getting into activ state (which at least is the cause for the malfunction).
This won't fix the short circuit between the signals and of course you loose trackball function, but this makes your phone partly usable again.
Cheers,
scholbert

thank you a lot Mr, it was so clear, will informe you for the progress

how to disassemble o2 atom xda

I somehow managed to get water in my screen so now the tapping function doesnt work. I dont know what else to do. I am currently in Beijing and bought it second hand so I'm not sure if the warranty is still in place and if so how abouts to get it to a retailer. The only thing I want to do now is try to open it up and see if I can try to clean up the moisture and water since its still there. I tried opening it but there are only two screws at the bottom back side of the unit that are available to me to get to. I'm not sure how to go about and disassembling the whole thing. The pda is really important to me since I use it as a chinese dictionary. I dont know what else to do. Any help would be appreciated. Bye

Firstly, you can check if it is still under warranty by registering it on O2 website, you will need the original receipt to claim warranty (and moisture damage is not covered by warranty). Secondly, if you want to fix it yourself and I dare say its too late as the battery would need to be removed immediately as moisture enters the device, even if you manage to get an LCD (roughly US$250)and you're able to fit it there's a posibility the main board and components are damaged too. However, I have repaired to some degree with many tedious hours of careful cleaning with pure Ethanol. My advice to you is send it to O2 for repair and do not put the battery into device!
can you tell me how to take it apart? everything seems to be working fine, just that certain areas on the screen i can't tap. I know there are two screws at the bottom back side of the unit where it says void. But other than that I dont know what else to do to get the unit open.

the housing for the camera must be removed, very carefully, under that cover are two more screws.

Killed my MDA II Compact?

Dear Forum Users,
fist of all sorry for the fact that my first post is a request, a question and not a contribution - but im really dependent on your knowledge.
Despite the fact that in general it is not recommended to change the cover of your mda (or xda etc) I did it, and seem to have f***** up my display. The device itself is working just fine, i can do active sync, the taping also works (when i switch it off and guess where the yes button from "do you really want to turn off your device" is it actually shuts down properly). the thing is that i dont see anything, its just plain white.
Image:
http://content.imagesocket.com/images/CIMG4803_Small_805.JPG
when dissecting the unit i disconnected the connector from the display to mainboard in order to unmount everything (unfortunately i discovered afterwards that i could also have done it without connecting - dumb philipp :/ , but right now that doesnt change anything for me)
has someone dealt with a problem like mine before? i would be really thankful for any hints or advices to get my baby back to life, otherwise my old vk2000 will be my companion for the next 6 months (i shiver when i just think of it).
thank you in advance,
Philipp
Have you tried to disassembled, and than reassembled it again?
some times the display flat cable, isnt fuly inside the connector...
there is a possibility that you f*** up the connector, but for determine that we need a macro picture of it.
yes i messed with the connector indeed, but as the pins of the strip were down i thought the black piece wont be of that much importance (i can remember i ****ed one up at a regular mobile yrs ago and it was still working)
can i get that thing back to life if i try to squeeze the 2 black parts (formerly one piece) back in or do you say its over?
thank you for your quick reply btw, i appreciate!
http://content.imagesocket.com/images/conn2d8.png
That is not good. i dont think you can do anything but send it to repair. maybe they can replace the connector.
ok, i will call them and check how much it is and if it is even worth having it repaired... if not, then i have a defective compact for sale :/

Does anyone know a way in which i could fix this?
Cheers.

Mmmm. Tricky perhaps. A hard reset will either cure or leave you stuck. If you hard reset and the screen is indeed dead (touch wise) then you'll never get past the alignment stage. If the touch issue is software related then you would be sorted with the hard reset.
A gamble I think!!
However you are stuck at the moment so in a sense you have nothing to lose. If it ends up being useless then you are faced with a warranty (hopefully) repair otherwise some DIY though it's not entirely obvious what has broken/come loose - possibly just a ribbon connector.
Mike
Maybe the ribbon cable came loose on the LCD side?

Yeah i think its that as well, i hard reseted it a few times with no effect, in the begining of the day, it could still reconise the screen taps around 2/3 times before it totally went dead.
Are there any tutorials on how to open it up to check the ribbon?
Thanks.
This maybe the hardware problem with the mainboard itself. I read about this on here a few times, most people had the get their phones exchange....

Yes, I am equally unsure that this is just a simple loose connector. It may be, but it appears to be fine for a short while and only then goes off.
Like you myztikal47, I suggest going for warranty replacement if at all possible. Only if you have no warranty shuld you attempt a repair yourself - this is a notoriously ellusive fix and indeed I would say there is no 100% works for all answer. Certainly do not assume it's the screen - most probably it isn't and you'll waste your money.
There are dismantling links in this forum - but you'll find them on my small Hermes site http://michael-channon.spaces.live.com- go to the loose keyboard section and you'll see the links.

my 8525 had the same exact problem, and i swapped the LCD and still doess the same thing...
I dont know what the problem could be, and i dont have a warranty.

Touchscreen related problems

http://www.youtube.com/watch?v=uQ7csMbeQDA
The device screen doesn't react on pressings after running for some time, mostly running some more demanding application, in my case as seen in the video clip, a 3d game. The center-left part of the screen just won't answer to my touches, to get it more clear I've made a clip.
P.S.
The phone was bought in Romania (Eastern Europe), had been in service one time, seems all they've done is to resoft the phone.
Are you having a leather case or something that wraps over the side and front of the Leo? I can't see clearly but it seems so.

Have you tried hard resetting the phone? backup all your data and hard reset.

I did that (even in my video if you watch it); Updated to the latest firmware available on htc, same stuff.
P.S.
this issue appears mostly when I press the reject (power) button, so it's smth. with lower right corner...
I don't see why there's a discussion or even a post about this. The phone is obviously faulty. You say yourself that it's not a software issue so you need to take it up with your supplier. If they've already had it once and sent it back in the same state then you need to tell them that, not us!
They got to replace it. It's unusable in that state and no amount of software or tweaking will make the screen suddenly work for you.
i think the easies way is to send it for repair,
if i were you, i would do my best to identify the problem cause and be able to reproduce it whenever i want so i can go there to HTC and prove it.

Thank you for your reply, too bad the servicemen don't share this opinion, and the thing is more complicated due to the fact that I live in other country and have to ask some ppl to get the device delivered, and due to the random nature of the problem, it is really complicated;
the meaning of this thread was to identify, maybe someone has met such things, and knows what exactly causes the fault, so I don't receive the device the second time with "resoft" written on the service ticket...

that's exactly what I'm trying here - to identify the problem and get some proof, I can't go there by myself, we don't have an official HTC service - the nearest one is in Romania

[Q] Juice on Legend -> no more vibrate

Hello folks,
I spilled some juice over my legend and now it does not vibrate any more. Also the keys are stuck a little now - but i think that is the smaller problem.
Do you now what moduls i need to replace and where I can order them? I am planning on desembling the legend to clean the keys and other parts.
Many thanks.
Man, I'd say if you have to ask, then don't disassemble your Legend...
As the vibrator (a small DC motor with excentric weight on the axis) is the only movable part inside your phone, I'd say it's either stuck (glued by the juice residue) or the driver is fried.
In case the driver is fried, you'd actually have to measure what's wrong and where and replace the parts that are fried...
In case it is just glued, you'd have to unsoldier it and clean it...
Either way, it's pretty damn uncertain what will become of your phone when you disassemble it not knowing what to expect...
Thanks for your reply.
But I guess that disassembling the phone is a risk i have to take. What use is a phone today without the vibrator?
I never use it...
