water damage, no backlight..where is backlight control?
fixing this for a friend but I can't find any information on what's on the motherboard and whether the LCD has the backlight control. There doesn't seem to be any signs of corrosion or liquid debris apart from between the digitiser and the LCD (all cleaned up now )..powers up and charges but the backlight is kaput. I'm not at all familiar with this phone so I'm wondering whether replacing the LCD will solve the problem or whether there is another ic that controls it. Thanks for your time..Jen
Это хороший вопрос?

I can't find anything on the board that looks like it is a coil for backlight so have bitten the bullet and bought a new LCD. Also discovered that the phone here is called a Samsung "champ" but this isn't written anywhere on the phone.

I did find some service manual for the Champ. The flowchart is in Chines, but the rest might actually help out a bit. Just download it here Good Luck....:-)

thanks oldturkey, I'll see how it goes later on, but that should be pretty helpful. I've told her that a new phone is cheaper than the LCD but she loves her phone!
