picked up a tv and when the power is plugged, the standby light flashes real quick then goes off. of 3.3, 12, 24v is all there but i couldnt find any 5v on the back-end board. ON/OFF is low, which it seems is what turns on the backlight so i removed the wire at the back-end board and put a 10k resistor to the 3.3v, which when plugged in brings on the backlight for a split second and also a blue light "LED1" on the inverter board, which goes off after a short time.
am i missing something to bring on the backlight or is the inverter/ccfl gone bad? would that cause the inverter board to signal the back-end board that it failed and to not show a standby light?
thanks, hope someone can provide a quick answer (quick as in low-effort)
service manual is too large to upload as an attachment so here is a link:
