hooi76 · 11-08-2002, 13:42

I have a 3310 which have this problem, everything is ok, i try to reheat CCONT, COBBA and CPU, but still the same.
What is the problem.

At first, the prob is the PA of the phone is burnt due to charging but already replaced and evrything works fine except this LCD blur and now no display at all.

Those who know the answer please reply here. Thank you very much.

Most this problem is LCD connector to PCB!
try to replace that connector and clean PCB as well !

also check at VBB on C413 , 2.8V ! and check Vout at C410 , C412

it's not the LCD, i tried with a good lcd from my working phone, and it's still de same.
Does the CPU affected? I tried to reheat that twice, but still de same.

Thanks for your kind attention.

if you do not have test jig, then you have to make wire out to measure it !
