Re: LG 42PJ350-UB Sound, No Pic
Vs = 204.6V
Va = 60.6V
Vsc = 23.5V
Vy = 22.9V
im guessing its Y sus board since VSC and Vy voltages are too lowLeave a comment:

Re: Samsung PS42A410 has sound but no picture
Thanks so much guys
Ok I checked the buffer And there doesn't seem to be any shorts
I did find something strange the VSCAN solder tab where I tried to measure the voltage from that was showing 0 volts goes to ground
Here's a picture from the solder tab labeled VSCAN on the Y board...Leave a comment:
