Why does my TV keep going blank but the sound still plays?
Every time I turn my TV on it plays like normal for a couple of minutes and then it goes completely blank (black screen as if it’s turned off) but the sound keep playing like normal. I switch it off and back on and it’s back to normal for a couple of minutes then goes blank again.
I have tried to switch it off at the mains but nothing changes. How do I fix it?
