I have 820-3330 water damage in lcd connector area. Connector replaced and jumper for backlight was put in place. Board turns on, chime and everything but no image or backlight. I replaced connector second time to make sure that I got it right.
Gpu has power,
=PP3V3_S5_LCD - present
LVDS_DDC_CLK - present
LVDS_DDC_DATA - present
PP3V3_SW_LCD - 0 but it should be 3.
It looks like board doesnt detect LCD, so I ordered new lcd and flex. Tested and get the same result, no image or backlight.
Is there way to check if lcd being recognized? perhaps I got defective screen/flex?
Or what other signals do I need to check for image? all lines on the connector are present, no short
