Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.
I'm missing +3VLCD.
This is the circuit
With laptop OFF:
Values in LCD motherboard connector:
+VIN_BLIGHT: 19.55V
+BLONCON: 0V
+VADJ1: 0V
+3V: 0V
+3VLCD_CON: 0V
Also some voltages I assume are important... -
