dead front panel buttons + half working camera - 8525, TyTN, MDA Vario II, JasJam General

ok im on a dopod 838 pro with no warranty left
all the buttons on the front panel are dead but everything else works
i can still do a hard reset by holding left and right soft key and reset
i took the phone apart...cleaned it reassembled but still no go
is this fixable by ordering parts online or smashing/smacking some part of the phone? if so then please leave a link as to where i can get the part or where i should smack it
also...the camera only works sometimes...other times i would just see a few vertical red lines on the screen when i try to start the camera app then the app would show up black...this usually happens when i keep my phone in my pocket for a period of time...any easy fix for this?
thx

I have exactly the same problem with my HTC TyTn.

Its Fixable
i had the same problem as u do now but i had some time left in the warranty so i send it back to be checked ..they fixed it saying that there were a short circuit in the keyboard ..i'm not sure if they are right about the shortage thing but i'm sure that its fixable
good luck

white screen of death?

aright previously my LCD screen was cracked well i got the replacement LCD screen and it works fine. BUT my problem now is that its just displaying a white screen. Nothing else. I take off the battery put it back on turn the phone on and i get a white screen no letters no nothing.
Does this mean my phone is a brick?
i still get response when i hold down the comm button it vibrates. The volume slider responds with the volume going up and down. and when i try to hard reset via holding the comm button,voicebutton,camera button and hitting the soft reset button it responds to it and resets the phone apparantly.
So i know for a fact the actual phone works..but its not displaying anything but a white screen...is there anything else i can do ?
If you have replaced the screen yourself, it may be worth trying to re-fit it again. Make sure the connectors are in pefectly, and make sure there is no dirt on them. If the pda still responds to button presses, it's fine, it's only the srcreen that's damaged/non-functional...
To see if this is the case, try tapping on the very to left of the screen, and see if you get the start menu pop. If you don't it's prolly the connector not plugged in properly, if you do, then the connector may be damaged...
ok im trying now..but how could it be the screen if the screen is giving me a perfectly white screen and its been tested to be working correctly?
sweeet i reconnected everything and it worked thanks for the recommendation dood much appreciated

Nice to see that my reccomendation worked for you. I've never replaced a colour LCD screen before, but some of the B&W ones i've replaced have had similar faults. It's the same with old cartridge games if you think about it, you used to have to blow on them ocasionally...
Modern technology may be perfect in every respect, but the manufacturing methods arn't.

Wizard-Diffent colour vertical lines HELP!!

I got the mda vario from tmobile uk. I dont know what happen. Different colour blue, red, white vertical lines that start from up to down. If I connect the device to the computer or to the charger the orange light is on. PLease HELP ME!!!
Sounds like a graphics hardware problem to me - but worth trying a hard reset first - turn device off, hold comm and record buttons at the same time, turn device on still holding buttons - text should appear on screen, press green (call) button and hard reset should begin. Make sure you have backed up any important data before you do this.
im having this problem too, but my lines turn black and only effect half the screen. It starts with the screen going fuzzy.
I've had this happen when the phone was charging and it caused temporary screen burn because i recieved a text.
I try hard reset but nothing. It changes a lot of colours...
Sounds like a graphics hardware problem means that there is no hope?
Thanks anyway!!!

Isnt it under warranty? If it is get it repaired - if not maybe a loose connector inside, could be worth a dis-assemble and push all the connectors tight. Or if your not up to that take it to someone that is.
Unfortunately I dont have any warranty!!!
I find the disassembling manual but do you know where can I find the screws and other staff in the uk? Do you have any idea?
Otherwise I live in York Uk, do you know any place near here?

Hardware buttons doesn't work anymore on my Trinity.

Hi all, my Trinity's hardware buttons doesn't work.
The 2 softkey hardware buttons, the red and the green button, the ok button and the Start button seems to be broken also if they have backlight. All the others buttons are ok.
I've tried to softreset, hardreset and flash the ROM (I'm using last Ervius ROM). After flashing for the first time the buttons were ok for a littewhile but now they seems to be broken again even after several flash. I've also tried to downgrade to wm5 but nothing change. I think that is an hardware issue and I'm going to try to fix it by opening my Trinity hoping that is just a flat connector pluged out but if someone else has experienced the same problem and has to suggest me something is really welcome.

I experienced this myself, and replaced this item:
http://cnn.cn/shop/p3600dopod-d810-keypad-p-1825.html
HPN
keys are stuck
Mine also, but solved it after a couple of days (temporarily). The hardware buttons problem seems to be related with one of the keys stuck. If one of those keys is stuck none of the others work. I tried "fast" double clicking on one key at a time to unstuck and it worked for me. Mine has been working for two weeks with no problem. Anyway I ordered that part "just in case".
So before opening your trinity try to unstuck the keys. It seems to be related with humidity conditions and carrying the phone in the pocket (just a guess).

I'm going to try this becouse during the last 4 days sometimes the buttons work so.... thanks!
Ok, nothing work.
I've also tried to open the device but looking behind the buttons pad fortunally/unfortunally there isn't an evident hardware problem.
The only solution is to replace the pad.
Hi to all.
I have had buttons not working on my trinity for some time. was tempted to send it back for repair but i did not want to be without my phone and did not want to have to stick the old wm5 rom back on!!
I took my trinity apart too see if i could see anything wrong. and got it down to the keypad. one thing i did notice is that there was a lot of dust. also around the small disks that provide the buttons, there are 3 small holes in the sealing sheet. seems that the construction of the switch array is circuit board at the bottom, with small tin disks on top, all held in place with a thin plastic sheet.
The tin disks 'pop' inside out when you press the buttons, making the contact for the switch. On the old nokia phones, these disks got deformed and this would make the button work but with no click. I had a click but no button operation, and with the holes, and all the dust i found, i figured that it must be dusty contacts.
so here is how i managed to fix my buttons for free:
1, strip the phone to get to the keyboard circuit (i used this link clicky)
2, clean all the dust from the buttons
3, start to tease the plastic film from the front of the board (i used a sharp knife but mind your fingers and take care not to damage the board)
4, once one corner is up you should be able to slowly pull the film up (take care not to damage the disks as the plastic comes up but make sure the disks stay on the plastic sheet)
5, dont pull the sheet totally off otherwise you will have a job getting it all to line up after.
6, get some alcohol or head cleaning fluid on a cotton bud and clean all the gold contacts, as well as the insides of the discs.
7, slowly rub the plastic film to put it back where it came from, taking care to get the disks in the center of the gold contacts.
8, rebuild and test
All being well you should have working buttons again!!! It seems the design of the buttons lets dust inside the workings.
Hope this helps someone with clicking buttons but no action!!!

Touch Screen Not working.. plz help.

Hi mates yesterday i bought a used herm...with excellent condition. but when i opened any dialog. the window closed automatically. and the screen light remains always on. and touch is creating problems.
and after some time the touch screen totally stop working. i dont know what happened. al the buttons are working fine. i upgraded my t-mobile herm to its original t-mobile wm6 rom. and again the touch screen is not working. and the screen light always stay on..
so is this hardware or software problem.?
guide me if you have any clue about this..
according to my thinking.. i think some button is pressed continuesly.. but everything is working fine.. only the touch is not working.
broken digitizer for the touch screen, buy a replacement lcd/digitizer together and replace yourself, about $100Aud. Use Mike Channons site to download the service manual. Use the search function and type in "htc service manual hermes".
As for the light, you will have to use your buttons to navigate to settings>system>backlight>battery power and external power. you can select how long the backlight remains on for.
Cheers...
Hi mate thanks for your reply.. Actually the situation is that. the screen is working perfectly. all buttons are also working perfectly. but suddenly the touch feature stopped working.
that time i was just opening some menus and they closed automatically. it looks like that there is some button pressed. and the screen light never stops. it continuously remains on. all buttons are working perfectly and everything. on the touch feature is not working.
i upgraded my device with genuine shipped t-mobile wm6 rom and again it stopped at the starting screen where i have to click the screen and the device brings the window for stylus adjustment.
so i wanna ask that is this also possible that some touch drivers are corrupted or something like this.? or is this a hardware failure.?
Kind Regards
I had same problem, it was hardware. Thats why I said to change the lcd. It is theoretically possible to replace JUST the digitizer, BUT, it is a MAJOR hassle.
As for getting past the alignment stage, look up Remote Screen Alignment. Its a cab file that stores the alignment settings on your pc. You WILL have to have a friend that has the same phone so you can get their settings as you need to copy them to your pc first. You can then copy the settings to your phone so you can use it until you replace that pesky lcd...
Cheers.....
I had a similar problem with my hermes. After a lot of investigating, I found out that this is a heat related issue with the hermes. The unit will heat up an some connection somwhere gets messed up and continually registers ghost taps on the upper right corner of the screen, which causes the continual opening and closing of programs/task manager. This overloads the phone which then causes the screen to eventually become unresponsive due to excessive computing.
With my phone, it must be heat related because it will only occur during or after heavy use or overcharging. Other people have had this exact problem with the conclusion being overheating. The worse part is, there is apparently no way to fix this, replacing the screen doesn't change anything. setting your screen alignment very far left will fix the problem but then everything you tap needs to be compensated for.
Good luck, hate to be the harbinger of bad news, but it's better to know whats wrong and that you can't fix it then not know whats wrong and keep trying to fix it.
same problem here... only my hermes is overheating already after 5 minutes use...
in the morning it works and when i put it in front of the airconditioning the touchscreen also works...
somebody who has an idea where to look for a solution??

Some of the suggestions in the white screen thread/s might help. The problem is that those who have the heat related problem will find it very difficult to trace the actual fault. The heat may be causing miniscule expansions on the boards / components and connectors. The tiniest of cracks or poor connections can therefore break with the expansion.
Another theory is that rather than heat it might be a capacitor that is breaking down either over time or again through heating. Unless you are a skilled electronic engineer that is virtually impossible to check, particularly since schematics are not available.
You might just be lucky if you dismantled and re-assembled - it might just re-set a connector or adjust a board so it does not get affected in future. That would be very much a matter of luck and of course potentially the situation might be made worse!

Hi mates. I am back with some issue.. i moved my device to a repair center and he said that its a software issue. and he fixed my device without changing any rom.. i dont know how..
but again when i open some window like programs. the right scrollbar make a problem... when i move scrollbar it automatically press the top close button..i aligned my screen 3 times but same problem with right side scroll bar.
and after playing with it. the touch totally stopped.
now the thing is.all the buttons are working fine and everything is working fine. even sms and calls. but when i check sms and press my scroller button. it displays the right click menu instead of opening the sms. and the screen light is continuesly on. as something is pressed. so. i think this thing wil help. i am now trying this method to check my pc.
http://inuchanbt.blog54.fc2.com/blog-entry-99.html
check this out as well.
i will send you details soon.
might just have something lodged between the case and screen.. also to get rid of the screen alignment, cable it up and delete welcome from the startup programs and then reset it.. should get you past it so at least you can use it until you repair your screen

[Q] Incorrect Error Diagnosis at HTC Repair Centre

Hi,
I had the following problem with my HTC Diamond 2 (it might have got wet & it might possibly have had too much pressure on the screen)
Problem:
The mobile boots ok and the normal buttons at the bottom work fine, as do the volume up/down buttons. The display, however, has what looks like the newton rings and when I press the display it detects a 'press' about 1cm to the left of where i pressed. This means I can't use the right hand side of the display and also can't enter my pin.
Error Diagnosis: (from Arvato Services in Germany)
Mainboard is defect. Cost to repair = € 303.17
Is this possible ? If there was a problem with the mainboard then I would expect to see other problems - and at present, I can only see that the touchscreen has a problem.
Please let me know what you think, thanks in advance !
(ps there should be a question mark at the end of the 'title', don't seem to be able to edit though)
Based on your description and from what I've read, it's definitely the digitizer.
It is possible that you have a damaged board, but regardless, your digitizer is bad.
I would attempt to replace this yourrself then see if everything is fine before sending it to repair.
I had the same problem!
The screen was getting worse in alignment over a time frame of a couple of days. If replaced the digitizer and screen and all is back to normal ..... however it seems to work better then ever before.
The only problem left is dust between the digitizer and my screen, but this is my own fault since I didn't glued the screens. I'll re-open in the next few days and use some silicone to close the gaps. Mainly the volume key has an opening to the outside.
Good luck with the replacement!
