Hi
We have a 2 yo Panasonic 55in 4K UHD TV. When I switch it on from the side panel it comes on for 5 seconds , shows what the mode is and just switches off straight away. No picture visible, the remote doesn’t turn it on or off and then seems to go straight into stand by mode, I presume this as only there is a blinking light on the front panel but no picture or sound.
Anyone have an idea as to what it could be, it’s out of warranty and I got it from Noel Leeming..
Cheers
Iain
