55 inch 4k roku tv - picture blinking intermittently.

Bottom HDMI port just started making picture pause / blink to a black screen then everything is back normal. I switch to a side hdmi port and believe it is about 99% better. The t.v. is a little over a year old. is there anything I can check/reset to fix problem. Already have unplugged t.v. and reset. Tried different cable and same thing. Any help would be appreciated.

Hello sharkrc,

 

Welcome to Community@Insignia!

 

I'll be happy to look into this for you if you will please reply with your TV model number. Additionally, what device or devices are you connecting via HDMI?

Model # NS-55DR620NA18 Rev A . It was plugged into the bottom but thats bad. moved to side and the flicker and pops are knocked off by alot. tried my higher quality HDMI cable but does same thing. currently I have direct TV and a 8 camera system plugged into the 2 side ports. Doesn't seem to do it with camera system. Believe its the higher resolution messing with it. Had direct tv out and confirmed its the tv.

I did a system reset and re-installed everything but it still blinks and flashes. Seams ok if I am using video from like amazon. Just flickers thru the ports.
