Re: SONY KE-42TS2E-turn ON, then OFF immediately
Today I check Va and Vs voltages, and I found them with 2 Volts more then usually.
Va = 63,3 (noted on label panel) I found it 65,1V
Vs = 80.2 (on the label), I found it 82,5 V, measured with oscilloscope.
I putted them at correct voltage, from the label panel note and TV seems to run ok....
I don't know why, but I think that the problem may be some bad resistors .
When the TV was in run mode, I grow up Vs, at 82 V and TV stop immediately...that says that the protection are working at upervoltages ...And...Leave a comment:
