Hello,
I have an interesting screen problem. When i want to open the screen lock, i can't, i have to wait avarage 30 seconds.
After 30 seconds the phone work fine. I trought different roms, and kernels, I installed the original 2.3 but problem is same. I thought this is a screen problem, so i bought a new touch screen, and i hoped is gonna work, but
the problem is still same.
software or hardware ? any idea ?
should i buy a Touch Screen Digitizer ?
If it doesn't work, just flash stock and send it to LG for warranty repair or something. If this can happen with multiple ROMs, then the phone is probably defective.

Hi
Quick question. I don't know if anyone experienced that with Xperia T. I seem to have the same problem with it as with previous X8 and X10. Screen stays blank after switching on. Just backlight comes on but nothing else. Touch panel still responds as it should but no information visible phone is kinda useless. Just wondered if anyone knows how to fix this. Would it be hardware problem which seems to be going on for quite a while then in sonys mobiles or is it just software glitch? I would buy new screen but not sure if this will fix it.
Phone is updated to latest available firmaware. Done it yesterday with SUS.
Thanks

First I have heard of this probelm, so it sounds like just you.
Use PCCompanion to fix phone.
HAve you flashed anything to the phone, have you rooted it, have you unlocked bootloader.....

PC companion stops half way through the process. I've used the other standalone sonys update service to upgrade the phone which has done it no problem but still nothing visible on screen. Only brightens up slightly when switched on but nothing whatsoever visible.

Hi
Sorry, forgot to add earlier. No, nothing was done. No bootloader unlocking, no rooting, no other flashing. It just happened when I switched it on couple of days ago. I did have same/similar problem with X10 some time ago but along with just backlight on the screen (nothing else) but phone was in boot loop at the same time. This one just stays on for whatever time you want it and you can hear sounds and feel vibrating when using touch panel. Just trying to determine if it's something simple like faulty lcd (not cheap at all thoguh) or even if I splash out for a new lcd it will not help.
If you have not flashed anything, take it back to the shop for a new one

Hi
Yes I did. Fitted new screen! Only £160 pretty much the same as new phone now.
Was your phone damaged in any way (spilled water on it, dropped it)?

No man, she just was charging it up, then she plugged it out, and after that it was working but with the screen off , so is it a hardware problem and not software problem?

In my case was hardware. In yours might be not. I'm not that much of an expert so my only suggestion would be to do hard reset. Did you try that? Hold power button for about 15-20 sec.

I just have reinstalled JB Stock ROM and nothing, the Display is death, the weird thing is the Digitizer works, i can even hear when i touch the buttons, anyway thank you.
Would it be strange to suggest you should contact Sony for warranty?

Hello All,
My OB is bricked, i was flashing it with smartflash tool and installing official lg optimus gb image, but suddenly it was bricked. Now it is not starting, not even in download mode, no signal of power.
Any ideas?
It caused bcoz of loose cable connection.
While flashing any ROM, cable should have intact connectivity..

Probably a hard brick, bring it to a lg service center. Tell them you tried to update your phone and all of a sudden the update stopped and now it doesnt react anymore.

ok, but is there any other way?
In case of hard rest, as N00BY0815 said, only way is to take the phone to LG service center, but you have to take precaution regarding:
Take out the memory card and keep at ur home, in case you rooted the phone, otherwise they will know that U rooted the phone and reject the warranty.
i dont think rooting is against warranty everywhere does your pc recognises it when you plug it in while holding p
volume+ ?

He already said, it doesnt even turn on in download mode, so there is no chance to revive it. LG will not know, if it was rooted or not, since noone can turn it on and check it. So just do what i told you above and everything should be good again

This is software error not hardware error. They can't charge you buying new free software.
If its hardware error, in this case, then the problem is not caused by the root and they can't reject warrenty (at least in Europe, I'm pretty sure in most places they'll get away with it.)
EDIT
@Nooby
If they can't access it through new bootloader they have to use JTAG equipement and then you can read and write to flash memory.

I have not much knowledge like xonar and N00BY0815,
Maybe they used JTAG or something ..bcoz at first they try to know whether it is rooted and non-rooted to get reject the phone here.
At that time, I contacted the most senior developers here in XDA, they also suggested that there is nothing to do if the phone is not turning on, & take it to service center...(the case is of LG P500)
That's strange. When I hard bricked mine, they kept my phone 3 weeks to finally say that it was the motherboard which died (I flashed a P990 rom by mistakes, it was for a friend but I forgot it in my sdcard).

11 days ago i installed cm10 nightly 11-14-12 after using the rom about 4 days, suddenly while charging my phone turn off and didn't turn on again. It can't enter sw upgrade. When i send it to the lg service center they said that it was a motherboard problem and need to replace it. It cause P9,000 (about $214). What the F**K! The brand new Optimus black here cause around P13,000 ($309). My warranty is already expired so i decided not to replace the motherboard and wait for the release of nexus 4 here in my country.
That time i'm using blackberry charger 5v output. Do you guys think that the hardbricked has also something related to the charger?
As u can see in the picture..im facing touch screen problem.the bottom of screen is not responding..any help guys??

1-did you recently dropped your phone?
2-was it like this before an update or something that you have recently installed? back track
3-perform a repair through sony pc companion or sony update service

not a solution, as I did it already twice, after a week or two you need to do the same. Probably the only option is to change the motherboard.

Hello i had same problem with phone. Totally dead, then i read on forum that it is probably pmi8994 chip on motherboard that was defected. I order that chip from aliexpress( must know what version is chip on your phone). Mine was pmi8994 002. I paid 8$ on aliexpress for two of them(you need only one) and 35$ for replacement. After replacement it come alive and working fine more than half year. I hope this will help.

It was suddenly power off and didn't want to turn on. I put it on charger (before failure battery was around 70%), but it didn't power on and notification light for charging was very dim and blinking. Then i check my domestic forum and got solution from one user who had same problem.

How did you change the chip? I saw a video on Youtube that describes the procedure of changing a chip, and looks like it is definitely nothing for laymen.
