Why is my screen intermittently flickering with horizontal lines?
TV screen has apparently normal display, interrupted every few seconds by horizontal lines https://youtu.be/CFx9Tk5bINY
Possible contributing factor is 2 year rampaging around house during lockdown, but didn’t see her do anything to the TV immediately before this started earlier today.
Have tried unplugging everything, reset to factory settings etc. Still happening so seems to be a hardware problem. No obvious damaged/loose connections inside. Any ideas on likely cause and how to proceed?
Is this a good question?
