Hi. Board has an Image but no Backlight. This board started as an lcd connector replacement to regain backlight because when old connector was tapped the backlight would go in and out. Tried known good working LCD. So I changed the connector and it seemed to work fine for a bit. Then backlight started going in and out. Now there is none at all.
F9800 is 12 V
PWM is 2.8 V
BKLT EN is .002 V (missing)
PPVIN is 4.93 V
R9731 .002 on pin 1
When I take measurements on pins 4 and 6 on Q9807, backlight starts to come through dim. Is this a grounding issue on Q9807? I have already replaced it.
Thanks in advance. Have a good one.
