Unusual black screen on wake-up...?

I'm getting a black screen when I turn my tv on after the tv has been off
for a while, no frontend.

mythbackend is still running as well as mythfrontend, the screen is just
black. In order to get the frontend again I have to exit the frontend and
restart it before I can see the main menu again.

Anyone else having similar problems or have some suggestions for finding out
what might be going on?

Thanks.

A dumb question, but have you tried hitting keys/buttons on your remote?

Yes, it's like its screen saver mode or something here is some info from the
backend and frontend for today when I tried to login and I see black, maybe
it would help?

Re: Unusual black screen on wake-up...? [In reply to]

I had the same problem and it took me awhile to find a solution. It
was like a screensaver but I couldn't find anywhere to turn it off.
The issue really hurt the WAF. Anyhow, I have a script to turn on my
TV and these lines fixed my problem.

xset -dpms
xset s reset
