Hi, all.

Got an A800 samsung, with no light on main lcd.
Small lcd lights up so magnet is ok.

Phone had some waterdamage arround connector part.

Anyone knows which pin off connector supplies power to main LCD backlight ?

Thanks

You need to change flat cable.

you need wire from ic near lcd to connector to pcb.
Scheme can be downloaded from thienlong.com ( or something ... i forgot the site name ...)

Usually is the EL (the back light) damaged or the coil beside the EL burned it's easy to trace it, just pay more attention

good luck!
