Yamaha RX-V3800 - Intermittent Picture Problem


I got hold of a Yamaha RX-V3800 a few days ago for £100 (quite cheap, it seems). Lovely bit of kit but an occasional slight problem with the video.

I've got:
1. Sky HD Box -> HDMI -> Yamaha
2. Apple TV 4th Gen -> HDMI -> Yamaha
3. Yamaha -> HDMI -> Telly

The sound quality is great. Picture is perfect from Sky HD but from my Apple TV I sometimes see green speckly/pixellated splodges on my screen. I've swapped my HDMI leads for hopefully better quality ones (HDMI 2.0 high speed 4K blah blah), but the problem remains. If I turn the amp off and back on again, the problem seems to disappear (so far).

Plugging the HDMI from my Apple TV into a different HDMI port on the amp doesn't fix the problem - I wondered if it was one bad HDMI port but perhaps not.

Does anyone know what might be going on & if there's a fix for it?

Would a firmware update help here (I'm not sure which version of the firmware is currently installed - but I've downloaded the latest firmware files & installation guide from Yamaha's website)?

Thank you.
