Righto, so super strange one.


PS4 Slim with a Sony TV (5-6 years old, 55" model.... can't see specific model number as it's on the wall, but will find out shortly). Then there is a Yamaha HT amp.


The set up has been working fine for the past few months, but now (not played it for a week or so) we have no picture. And the TV just acts like someone is unplugging/plugging an HDMI in and out constantly.


Settings on PS4 I mucked around with:
- Fixing resolution to 1080p
- Turning off HDCP


Physical troubleshooting:


Removed the HT amp from the equation. So PS4 plugged directly in to TV - no video or sound
     - At this point tried another input 
     - also tried another HDMI cable (several actually)


Connected PS4 to PC monitor. Works perfectly, picture and sound automatically as expected.


So then connected PS4 back to HT amp, connected PC monitor to output of HT amp. Works perfectly. Sound through HT speakers and video on PC monitor.




Now the other weird thing is that other devices are working fine on the TV... Raspberry Pi, Chromecast, laptops etc. All work fine connected directly to TV and via HT amp.




So before I go out and buy a new TV, what am I missing?




But the biggest issue of all is I suck because the partner can't play Spyro.

I recently had a similar problem with my PS4 and I’m not sure what I did to fix it but I suspect it was something to do with the HDMI-CEC setting on the TV which I fiddled around with. The setting was either on and should have been off - or vice versa.

Sorry this is a bit of a crap answer but may be useful. You may like to have a look at that.

 Fixing resolution to 1080p


The TV might only be 720P ( it is from 2013-ish) !


Set this back to auto negotiate and see what happens

Sounds like an incompatible resolution.
I’d try what was mentioned, set the resolution to the lowest possible on the PC monitor & swap it over to the Tv.
If it works keep upping the resolution until it fails.
