Recently my media PC has been acting up. After a period of idle use the display (Panasonic TV) goes blank. So far the only way to fix it is to reset or reboot the PC, which always works. The PC is connected to the TV via HDMI out from the motherboard and into an HDMI port on the TV. I've tried swapping out the cable but same result. Perhaps the motherboard HDMI out port is dying? Seems weird that a reboot always fixes it though.

Next thing I'm going to try is going from display port out to the TV to see if that works. Note that the TV works fine with other HDMI inputs, including using the same port that the PC is normally connects to.

Any ideas?

Next time this happens, try Win+Ctrl+Shift+B which restarts the graphics driver. We've seen a number of graphics oddities in the last year, and this has been helpful in allowing clients to 'fix it' while we were investigating.

If that 'fixes it', I'm thinking its software rather than hardware and a graphics driver upgrade or downgrade may help.

We knew the HDMI port on our TV was dying when it started turning yellow. When it kept vomiting up electrons uncontrollably, we knew it was time, so we gathered the other electrical devices around its outlet to be with it when it passed.

The end was quite peaceful, a gentle "click click Bzzzzzzt" and a puff of smoke... and he was gone.

Brilliant! The first time it happened after reading this I used the key sequence and haven't had a problem since. If it happens again I will investigate the graphics driver change.

Thank you very much!
