everything seems ok but i have a problem with lcd backlight. it seems to have waves/black spots. it only come half way on the lower left. Is it possible to fix?
No need to check the resistors, just diode mode all the LED return pins on the LCD connector. They should all read the same. Could be corroded connector/resistor/trace or LP8550.
