TV, AVR or possibly DVR?

Occasionally the right 1/3 of the TV picture goes completely black!
Turning off the entire system (Harmony Remote) & back on always fixes the problem.

I has assumed it was my Cox DVR since it typically happened when using the info button & scrolling through channels. This places the actual picture in the upper right portion of the screen with the majority of the screen used to display program information. I’d see the right 1/3 go black & use the exit button to leave the info mode & return to the normal picture mode yet, the 1/3 black screen persisted unless I powered off & then on again.

I decided to “prove” this by waiting till it happened again & instead of using the harmony remote to power off everything to walk over & manually power off & then on just the COx DVR. To my surprise doing this several times did NOT fix the problem! I tried powering off just the TV & when turned back on problem fixed. I next tried powering off just the AVR & although that took away the signal from the TV the TV power remained on. THis also fixed the problem.

So I think it is either my TV or my AVR. I never had this happen while watching a BD or DVD or even while watching TV program just when I go into that info mode & even then it only happens occasionally.

So, I don’t know which component needs service! I doubt it is a cable as I have heard that HDMI cables are either 100% working or not.

BD player & DVR each have HDMI cable connected to AVR & AVR has 3rd HDMI cable to TV. Standard HDMI setup. Has worked for over 1.5 years.

I hope it is not my 65” Panasonic Plasma TV which is out of warranty. I wonder if there is some fuse or relay that lights up the right 1/3 of the screen & that is beginning to go bad? I cannot create the issue on demand so not sure how a service tech would even begin to troubleshoot unless it is a known issue. I’m hoping someone else has had this issue & solved it & can shed some light.
