Any TV repair boffins about

[mark st1]

My tv has developed a fault which I hope isn't terminal. It turns on fine after 2-3 minutes you get the occasional screen flicker after 5 minutes the picture just disappears. Complete black screen but full sound. Un plug it and goes through the same sequence ? Have tried Google to no avail. It's a
Plasma
Model no PS43D490
Approx 4 years old now will be gutted if it's died

is it a Samsung Tv by any chance, https://www.cnet.com/forums/discussions/samsung-50-plasma-blank-screen-problem-398573/

With TVs nowadays I am a firm believer in hitting them, if that does not work, hit them harder then buy a new one. I had a quote for a TV repair for a blank screen - over £300. The TV only cost £250 3 years previously.

Check if the tip recycles TVs, because it would be a shame to just throw it at the nearest convenient scrapheap:

They reckon it's repairable, so long as there's no smoke. Worth reading before the trip to the tip.

Does the blank screen just happen when watching TV programmes? Does it also happen if watching e.g. a DVD?

Tried it with sky box wii and DVD player same outcome. It's strange as the set is on perfect sound but nothing on the screen works no menu or logo or anything. Turn it off on same cycle happens

Old televisions had valves inside them like these pictured below, some of us are old enough to remember them

Have you tried hitting it hard on the top in the middle as per milk floats advice. That used to sort most problems out on the telly we had when I was growing up. It was a new fanged thing though as it didn't have any valves.

New telly time

Or no telly time, more cycle time.
