So i have this TV where it turns on by itself (green light immediately on start up) backlight turns on , but nothing on screen. Power supply seems to be working fine. I have checked the voltages , it has them written on the connector, they seem to be fine here they are:
2x 12v- Present
24v sound- present
24v LMB present
5v - Present
AC detect - 3.3 V
Power TV- 3.3V
Power Sig - 3.3
BL/On off - 3.3V
Option- 500mV
PWM - 200mv
This is the connector to the logic board , On the Backlight board i found all voltages present and on the PWM pin it also has 200mV
I think i have established that its the Logic board error , i have found one short on the board , And sure enough it gets extremely hot , cant even touch it
... here is the picture: The chip in question is g33 BPL , seems like some type of mosfet
I will try desoldering those few things around that mosfet , hopefully without damaging the nearby memory. Any thoughts on this?
