refresh rate issues and blank screen

Hi all
Is there a known issue with refresh rates ? I have a Intel dn2820 and also a chromebox both having same issue where if you play a file the screen is blank.

I then need to select another source on the tv or receiver and then return for it to work.im running version 7.0.2. Never had this issue before upgrading from openelec.

Not sure if this is known issue or not . Will try and get my head around this file logging if anyone thinks it's required.
Thanks for any help

Yes, logfile is needed

Hi there

Log file if I've done it right is

aRZP

I had to try different sources as I stupidly did a wipe of my hard drive by mistake , I meant to do the other option which keeps the storage. Doghhhh

Appreciate any help

Thanks

I'd say remove those piracy repos first: Official:Forum rules/Banned add-ons - Official Kodi Wiki

They have already been removed cheers.
Any ideas what's causing the issue? I've done another resetting to default with no luck.
Cheers

Update to v7.90.004 when it's released (soon ish) and retest. If there are still issues submit a fresh debug log that clearly shows a system with no pirate crapware installed.

Will do, thanks

i have the same issue, its easy to reproduce, just change the framerate from 50 to 60 and back a few times you get a black screen, I have discuss this with fritsch a few month ago, i looks like a kernel bug. I hope v7.90.004 fix it :>

Yeah fingers crossed they can get the bug sorted . It's not a big issue just annoying really .
Apart from that everything now runs smoothly after switchover from openelec.
