Panasonic TH-50PZ80U Plasma No picture no sound no blinking error

[smoa]

Hello. I have a Panasonic TH-50PZ80U Plasma TV. 4 weeks ago I had no video for about 30 minutes, but then, everything started to work fine again, but not because of anything I did.

Today I am watching a show on the unit and I loose the image. The unit was still powered on and primed. Remote control access all works including power, vol, menus, etc... Red Power LED steady on and no blinking. unit DOES NOT power off by itself after 15 minutes.

I was using HDMI input but tried component and composite, with same result, no picture.

Any ideas for next steps of diagnostics please?

Thanks.

Pull the back cover off and look for any bulging or leaking capacitors, or any other obvious problems. Be sure to leave the tv unplugged for several hours before working on it.

Most likely an A board fault. Try disconnecting P5,P6,P7 on power board and LVDS on main board, when TV is powered on so you get a full white screen?
