Viera TC-P55ST30 flickering snowy picture

TV has always worked great (2011) but recently has a lot of snow usually while using as computer monitor & is worse on white page. A lot of flickering & snow. Also much worse when cold or at start up. It has most recent firmware update (2220-1000) & I've set it back to defaults which has made it a little better. It works not bad after it warms up but is getting worse at start up & I figure it will fail altogether one day. I've already replaced it with a 4K LCD but I'd still like to repair it if possible & didn't cost too much. I haven't taken it apart so I have no idea what's inside. We no longer have any TV repair shops around & it's too big & heavy to take too far & I'm pretty handy if I could get some advice what to try. Thanks. Eric

You haven't said what TV repair skills you have - poking around without the basic skills could prove dangerous or worse - lethal

Thanks for your concern for my safety larkone. Do you have any idea as to my technical problems with this TV?

Any blink codes? Power supply issues are quite common.

No blink codes. It starts fine. It works better as it warms up but when it starts I see ghosts of images under whatever is on the screen as the picture flickers. When I 1st noticed it, it seemed to be just the top 3rd or worse at the top 3rd. Now it is the entire screen, although still worse at the top & seems to get worse every time it starts. Dark images or scenes in a movie (when it warms up) look pretty good but during lighter scenes or images (like a web page when used as a PC monitor) there is snow but it appears to be black snow. Not multi coloured snow just black specks. I never liked the issue of ghost images & screen burn with this TV but now that I've replaced it with an LCD (RCA RTU5540) the plasma is/was a better picture. I don't expect anyone to diagnose (properly) this TV by text & I wish I had made a small video I could attach here but it is disconnected now (I could hook it up to something I suppose) but I think I'll give it to a friend who repairs TV's as a hobby if he wants to attempt to fix it he can have it. It is so big & heavy I'd just like to get rid of it. I was hoping I could fix it & sell it but I'd be happy now if someone would take it off my hands. Thanks for your help.
