Facing TV Problems? Ask a TV Technician.
Hello friend, Thank you for posting your question on Just Answer! I will be happy to help you with this problem, And possibly help you save on these Labor charges today, So please don't Accept my answer unless you are satisfied,
VS VA VSCAN ALL THESE VOLTAGES ARE GOOD?? CORRECT
If so then the issue is the Main,, or logic board (SCALER BOARD)
Tried replacing the scaler board. Same problem, no difference. VA, VS, VSCAN Voltages are all good.
Sound is good, no picture at all, screen does not even light up for startup or volume, menu, etc.
Any other ideas?
what about VE voltages please tell me all the voltages you read,, the label from the Panel should guide you,, because you never mentioned the VE voltage or any voltages for that matter,, so start now take measurements and tell me what they are,,
read everything on the X- board please
Voltages constant from PSB to Y-main to Z to X
VA = 58.1V
VS = 196.2V
VScan = 7.19
5V = 6.44
Vscan is low - should be 12V?
5V is high - should be 5V?
You're going to tell me that the Power Supply is bad right?
If you remove the back you will fine a couple of caps that are bulged and they need to be replace, or you can buy a new power supply at www.partstore.com. If you want to just purchase the caps, you can get them at www.mcmelectronics.com.
