Hi everyone, I have just acquired this Panasonic TX-49DX600B 4K HDTV, which is to all intents and purposes totally dead. There is no power LED, no picture or screen brightness, no sound, nor any response to the remote control.
However, there is power on the TNPA6232 power board, mains in, high voltage on the main caps (450V, rising to 600 odd volts - and the caps are only rated at 450V!) and 80V rising to 100V and 18V rising to 24V on the top centre caps. Inititally, the voltages are at the lower figures, then after a minute or so, the higher voltages can be measured, but the TV still fails to show any signs, or respond to the remote control. I daren't leave it on very long, as the main caps will likely blow!
Does anyone have any experience of these, any known/common failures, known voltages to check, or a circuit diagram? Any help much appreciated, thanks.
