W800 & K750 No backlight ? - GSM-Forum

Hotdog · 01-10-2006, 16:09

Recently had a few Sony Ericsson phones bought to me with the same problem. They all have no lights on the screen, you can see the screen and all works ok, bar the backlight. Now its always due to liquid damage. But just wondering if anyone has a fix for these problems, fitting new screens does not cure and neither does flashing, so looking at a hardware repair??

in regards to that - does that have to be replaced or will a reflow cure this?

well, a reflow didn't sort that out - so i'm assuming that it'll have to be replaced?

if you are technichcian ,first find display hight voltage pin (obout 6 to 12v) then use coin connect from this pin to LED'pin on display .If Display is very bright ,you can connect over Resistant.
