Hello. These vertical lines appear sometimes especially on PS4 when HDR is enabled in certain games (also occurred once without Hdr enabled but higher frequency of occurrence with hdr enabled). Sometimes there's just one and it moves as can be seen in the video attached. Sometimes there's two of them, one is static in one place and it flickers, the other one moves vertically.

It has only occurred once on other hdmi device which is a digital receiver.

It has never occurred on non-hdmi content e.g when playing YouTube or Netflix on the TV itself or any media played via USB Drive.

This has happened roughly like ten times in last 8 months since I first bought it.

It gets fixed if I change source back and forth.


What could be the possible reason behind this?

TV Model: TCL C716 - 50 QLED
 
hi, this is interference in electric signal, which means your hdmi cable is picking up some electric noise, u can get better shielded cable or try ferrite beads (filters)

another possibility would be noise comming from wall outlet... any electrician should be able to help with that
