Panasonic TV TX-32LMD71F black screen green LED flashing

Hello,

My old Panasonic Viera TX-32LMD71F TV suddenly turns off (black screen, no sound). After a few hours or days, we can turn it back on, but the problem returns in 5 minutes.

I changed the power supply board. And there you go, everything was working well.

Same problem and same symptoms after 2 hours with the new power supply board.

Any idea what could be happening?

Thanks

    Can there be a return through the HDMI that would send a surge or something that could fry something?

    The problem occurred when I switched to HDMI2 with a Chromecast (an HDMI hub).
