Backlight not working - 8125, K-JAM, P4300, MDA Vario General

Yes, it's true. My Wizard revived, but with a small problem: the backlight doesn't turn on not even after some Hard Resets and even on bootloader mode, the screen is dim all the time.
I've also changed the settings on the slider with no success and searched the forum and found no answers.
What can cause this and what is the "cure"?
Thanks in advance.

Thanks for the tip. Is there any way we can fix the light?
The screen works, the touch works, but it's far too dim to use it.
Anyone else?

You say you have hard reset it, but have you tried flashing a different original rom to it to see if that fixes it? It might be a hardware problem with the lcd but i did have an issue once on my himalaya after flashing a new rom and i couldnt get the backlight to work, but after flashing an original rom it worked again and then i reflashed a cooked rom and it still worked

I'll try that!
I've already flashed the original one...maybe flashing it with something else could fix it...
Thanks again

OK, just reflashed with a WM6 ROM (TNT.1933_Professional___HTC_Home_Wizard.rar) but it's the same. I can barely see what's on the screen. The screen works, the touch works, but it's too dim to use it.
So maybe it's not the backlight, I think it's the front light...
I also have dismantled it and cleaned out the contacts, re-assembled and flashed it again with no luck...
Help?

WM6 ROM (TNT.1933_Professional___HTC_Home_Wizard.rar) <---- that isnt an original rom, i am on about a operator rom that was officially released for your device, i.e. mine is an xda mini-s so my original provider would be o2, so i would use an o2 rom update that was released by them.
What you have basically done is install a cooked rom from itsright. Whoever the phone was released by try flashing their original wm5 rom to your device to see if it fixes it. THEN try flashing the tnt rom

Ok, some new developments. The LCD is fine and working and there's no problem with the backlight. I've manage to find that the issue was the mainboard all along.
I've used another LCD (a good one) and the backlight was still on, so the problem might be the mainboard is fried.
So, anyone can help me out? I just need a new mainboard (can be with the USB Connector in bad conditions, cause I have some solder skills).
Please help me out.
Edit: The Thing now doesn't charge properly. After some time, I get a flashing orange led and my Wizard heats up like it's going to blow...

dead bottom buttons

hi all, i bought a tytn at ebay, but
the after a short time of using the bottom buttons, they stop working.
touch screen and buttons on the side are stíll working, but the bottom buttons are dead.
sometimes after turning off amd turning on they are working for a short time again. a restart also helps to make them work.
but its not funny to restart every 10 minutes.....
it is an e-plus tytn from germany with wm5.
do u guys think that it is a hardware or a software error?
I seem to have this problem on and off myself and think it's related to either the rom on the phone or the radio rom but am not sure which. It seems sometimes I have this problem and it seems to come and go depending on what combination of rom/radio rom I have installed. If I was smart I'd find a combination that works well for me and stick to it but I always like to play with things so typically every day or two I'm reseting
yeah, i have the same problem.... i hate to restart the phone every now and then, but I need to figure this out sometime soon, or I'm gonna upgrade to WM6 to see if that solves my problem. lol...
did anybody else have an idea to solve the problem?

http://cnn.cn/shop/8525tytn-flex-cable-p-1732.html
I opened up my tytn, to find out the problem, and I found a small crack in the flexcable mentioned above.
Before it was never opened nor did anything strange happen with it, so this seems to be yet an other production problem/fault..
More and more people seem to have the same problem, time to presure htc for a repair....
Ok for me this is too late, but all for the good cause.. will just order myself a new cable and try to swap it..
Any ideas where to get the flex cable these days? Not finding it at the link above and internet searches aren't panning out either.
FYI:
Just got back my HTC TyTN from service under warranty, sent for exactly the same problem.
The technician I spoke to directly said that maybe about 90% of the lower keys malfunctions are caused by the lower keyboard board behaving erratically and it is a well-known hardware problem.
A board replacement solved it, my TyTN is working perfectly again, they also replaced the stylus holding rubber (which was broken already from the early days) and, surprise, they upgraded my WM5 device (I had to revert everything to the initial versions before handing it to them) to the latest official HTC WM6 Rom. Even bigger surprise, although what I gave them was a WWE device, when I got it back they had upgraded it to the localized (official Greek) version. Life is good.
Anyways, seems the only real solution to this is a visit to the repair store, hopefully under warranty and reverted back to the original settings...

Elf won't start

hi all,
I've a problem with my htc touch, it doesn't won't to start !
everytime i turn it on it turns off right before the HTC welcome screen comes !
any idea what is that ? or how can i flash another rom ?
*it's fully charged
*my rom is Touch_of HD lite 3.0
Thanks
Hi,
Did you flash a new rom or something recently? How old is your battery? If possible....try changing the battery and giving it another shot.
it's a new battery about 2 months or something
yes this is a new rom i flashed it yesterday !
Thanks for your quick response

Hmmm...there you go. That seems to be the problem. Perhaps you'd want to go back to the thread from where you downloaded the rom and check to see if anyone else has had similar problems on their device. Or maybe try to get in touch with the person that cooked it. You can PM them or something. I'm sorry but beyond this....I cant tell you what to do....I've never flashed a rom on my device. Still learning Perhaps someone else on this forum can guide you.
Good Luck
Thank you but i don't think the rom is the problem,
I entered the boot loader and tried flashing 2 different roms and the same thing happens right before the HTC welcome screen "the animated picture where HTC logo appears" the device turns of !
so what is that !!!!
any help please
mine like the fridge!
For troubleshooting, try to cool it in the fridge for some minutes before you turn it on. If this helps, then I have no idea what causes the fault! But you are one step closer by knowing if its a hw or sw issue
If this helps, then I have no idea what causes the fault!

lool
I tried what you said but didn't work too !
I think it might be the RAM or something .. what do you think ?
could be
I've red somewhere that its a RISC controller in the Elf. If so; it contains a RAM itself. So even tough I'm not a specialist on this things I belive that it could be a internal fault in the RISC or the multiplexer to the external RAM or the RAM itself. These things are all a motherboard issue that needs a replacement - in other words a new phone!
If its a SW problem it should work fine with the orignial ROM. On this field I shall keep my mouth shutt 'cus I know nothing about phone/smartphones!! I do think you should make it to the bootleg whit any ROM.. I belive!
have you tried to hard reset
1) Simultaneous press and hold "Power" and "Camera" key.
2) Press "Reset" once with the stylus and then release all keys.
Yes I've tried hard reseting !

That's a relief
Have you tried flashing one of the original roms onto your device? If not....give that shot. You'll find a list of all original shipped roms on the wiki.
I'm not sure
If the mailfunction started after you ROM-flashing "upgrade", then its more likely that its the software. But I know nothing about software on this things or what the symptom may be if theres a missmatch on the phone configuration/model and ROM.
guys I've tried everything even original roms
I think i've to change the board !
Thank you all

Urgent help required (touch screen problem)

i have a mda vario 2 ( hermes) i've been installed a rom called hermes_wwe_3.62 Malina2d now phone boots up fine but the touch screen dose not work at all ! can anyone help ? .
To get pass the alignment screen i had to create a file on storage card " welcome.not" and that got me pass alignment screen.
now i am a newbie so please all the help would be appreciated i did have a look for file called touch.dll to replace it but could find one. ( as i read somewhere that might be the problem.
my ipl -1.04 & spl-2.10.01ipro
i really don't know what to do i have tried to re flash the rom no luck there.
all the hardware buttons work fine.
Not sure about that one. Why not post the question in the thread from where you got the rom? That name doesn't ring a bell.
If not try flashing the stock shipped rom, or the at&t stripped to see if the issue goes away. If it does go away, then don't use that rom.
cant really remember where i got the rom from as i the phone is my little sisters. do you have a link for the rom you suggested
My sig has the stripped rom, and the shipped at&t roms. You can also find some programs and my roms there too.
And to be safe make sure that hardspl is installed.
If that doesn't fix it, there might be a hardware issue.
cheers for your help. i am going to download one of your roms and pray that might resolve the issue . what the latest hardspl ? i thought 2.10 was the latest ? how do i tell what is the on i have installed on the phone ? Hardspl and spl are they the same thing ?
If you flash one of mine, flash the at&t rom first, that will straighten out any issues with the memory.
if you have 2.10olipro, your all set! spl (or hardspl) is the bootloader.
no luck still having issue with the touch screen wont wont work.
the touch screen used to work fine before. all this it just became very laggy so i decided to upgrade the rom , i went to thru a few roms.
any other idea ?
i must say i do love your rom everything is set out all nice and neatly shame the touch isn't working.
Thanks for the compliment on the rom!
Sounds like it has some kind of hardware issue. If your inclined to take it apart carefully (I haven't taken mine apart yet), you might be able to check all of the connections, and for dirt or anything that might be the issue.
I believe there are disassemble instructions on the wiki.
Maybe someone with more experience in taking the phone apart can chime in.
touchscreen issue
i m having the stupid touchscreen issue i have tried everything ( including disassembly and removing gasket but it still does not calibrate
starting to hate that phone
Sounds like Digitizer could be dead.... Need to replace the LCD and Digitizer if thats the case.
The trouble with this is there are a few different things that could be causing this and just replacing the LCD might not fix it.
Sounds like it could be though. If you are having trouble, DON'T do a hard reset until you have installed an app called "remote screen alignment", freeware off the net. It copies the alignment info to the PC so you can do a quick alignment using the PC instead of the buggered screen. Otherwise you'll be going in circles for ever without being able to get into the today screen.
Cheers...
actually i have hard reset the device
the trick is to put a file called welcome.not on memory card to skip first time alignment
i'll change screen and see if it fixes itself later
i ll use the phone as it is till then
new lcd
i changed the lcd it worked flawlessly for 3 weeks then bang! the bottom half of the lcd stop to work
i think that the ribbon on the lcd got damaged when i installed it on the hermes the fact that it needs to be turned 360 degrees during assembly cause the problem any thoughts from you guys????

Touchscreen does not react

Today I used my HD like always. When I picked it up and tried to unlock it, the screen did not react. It does not react to any kind of push on the touchscreen or on the 4 touch buttons. The device starts as it has always, but I can't do anything with it. In the last couple of days I have not installed any additional software, so that can't be it either.
Soft resetting does not work either.
The device is fully loaded, has updated original rom.
Can anyone help me
Try HardReset (VolUp+VolDown then 1click PowerOn, follow display): if this isn't usefull -> Customer Service
D'rath
PS: HR erases all
After the hard reset the screen goes to a message saying: tap screen to set up your device.
I still can't tap the screen so the hard reset ends there...
Is there someone who knows a solution, if not I will have to send it back to the factory or something.
i had that bother with mine, it turned out that it was the orange rom that was causing all the problems. I put in dutty's 3.4 and that solved it
My provider is T-mobile. This means no special rom is on my hd. Is it wise to put Dutty's rom on my hd, with the thought that i might want to sent it back to HTC? Can I after putting Dutty's rom on it and finding out it still does not work put another rom on there leaving no trace of dutty's rom?
If you still have the original rom on it, seems to me that the best option is to send it off under warranty.
+1 Anfloyd say true ^^
Better solution if under warranty
D'rath
Most likely a fault with the digitizer. Happened to mine and quite a number of others. I had mine fail and had to get it repaired.
Than that is what I will do.
Thanks for the advice all!

I have same problem with my HD!
So what was cousing problem - software(ROM) or hardware?
And did waranty cover it?
I have this with most of the newer ROMs and with all W6.5 roms.
Try to flash to a version from around april of this year.
I have this problem also - luckily for me I live in Milton Keynes and the HTC repair centre is just round the corner from me. I have taken it there for repair under warranty. Will let you know what they say when I get it back....which hopefully will be today.
Hi guys ,
i have the same problem .
Touchscreen stopped to work. It was up but not possible to tap anything.
I think to change digitizer and then all the lcdscreen.
Is possibile to change only the digitizer ?

yes it is possable to change the digitizer but it is easier to replace both digitizer+lcd

[Solved] [Q] Screen Alignment Not Working Properly

Hi all, I've been searching XDA-Dev for a while looking for someone with the same issue, and although I've found similar issues, nothing really helped much...
A few days back, my HTC Touch (ELF) started playing up a bit; the touch screen alignment was a fraction out, not too bad, just irritating. When I tried to re-align the screen (Start > Settings > Screen > Align), it showed the alignment screen with the + symbol. I went through the taps, and after the final tap it's supposed to go back to the 'Screen' settings window, but instead the re-alignment process starts all over again. It got stuck in an endless loop.
I thought a hard reset would fix it, so after backing up all my data I tried it. I still have the same issue, but now I can't get past the alignment screen during the initial device setup, so I can't use it at all..
Just to give a brief run-down, here is what I tried (in this order):
Re-align - No luck, got stuck in an endless loop.
Hard reset - still stuck at the alignment screen.
Re-flash Onyx 6 R10 ROM - same problem.
Try flash different ROM (Onyx 6 R11) - same problem.
Tried re-flashing HardSPL 2.28 - same problem.
Tried installing different version of HSPL (tried 2.26 and 3.10) - SPL doesn't change, problem persists.
I'm going mad trying to figure out what would cause this, I haven't dropped my phone or had it anywhere near liquid or large magnets, so I doubt it's a hardware problem. But at the same time; if it is a software issue, why doesn't re-flashing Onyx ROM fix the issue?
If somebody could help me with trying to get my HSPL replaced, that should either fix it or at least rule out one possible problem.
Anybody got some ideas...?

Its hardware - your digitiser needs replacing. You can run msp_remotealignment which may help push it through.
Better idea yet, use the search feature, there has been a few of these recently which have all teh information you would need.
For HSPL, look in the rom section and post in the right thread for help with that I guess.

And yeah, I'll try there (again). Only reason I asked here was in case the problems were software related, and if so that was one part of my device that I couldn't change for some reason.
Well, since I can't seem to find any more helpful information, in the mean time I've ordered a new digitizer... Once it arrives, I'll replace that and see if that was the actual cause of my problems.
if you get stuck dissambling, theres the guide in the rom section I think - its very detailed and should help.
Sorry i couldn't be much use, Its hard to be when at work.

Thanks, I do remember seeing that guide a while back and (ironically) thinking to myself "I hope I never have any need to do that"... And don't worry, I know what you mean; I'm at work as well. I don't have internet at home unfortunately, so at work is the only place I can really get online.
For the sake of anybody else that has the same problem as what I described here: replacing the digitizer worked perfectly for me, I got my phone up and running again last night. This would've all been done a lot sooner, but I was struggling to find the right screw driver to dismantle it (requires a Torx T5)...
awesome, glad you got it all fixed now
