Hey Nerds!
New Member to the Forum! So I will give a brief introduction. If you prefer to skip to the question then just read the next paragraph.
I have been fascinated with electricity since I first stuck one of the old man's screwdrivers in the little crevice between the right side of the receptacle and the box and of course hot and ground have been sworn enemies since day one. That bright flash followed by the instant darkness sparked an interest. I didn't even flinch...I just smiled. Since that day I was always taking something apart. At age 12 I first laid my hands on a crummy 30w soldering iron and since that day I have always been tinkering with something.
Now I need some assisting advice from the more "advanced" nerds in this community. My dad got himself a nice new 4K Smart TV and my dad handed his reasonably new Panasonic Viera from 2013 paid a pretty decent amount for it at the time. However, it was a demo unit at the local Wal-Mart and most likely already had many hours on it from the start.
Then my Paternal Grandmother had developed agoraphobia and ended up running a couple hundred hours into it while she was taken care of. It worked perfectly up until about two years ago it started to hint it's troubling issue. Once in a while, It would display wacky colours before dying and then powering itself back on and returning to normal operation. Not a big deal.
Anyways skip ahead to around February I had been using the TV with increased trouble but it was usable. (Starting to wonder if my dad got a new TV for THIS reason.) Then the issue became unavoidable. This was it's routine. Power on, crazy colours with a fuzzy picture, power off, power back on, work fine for about 10 seconds, then power off again. Rinse and repeat... I unplugged it took the back off inspected every board on it to find no obvious issues. And thats where it sits. My first thought was power supply, but with more advanced circuitry such as a TV, I can only assume.
Hoping to breed more life into this TV provided it's not cost prohibitive. Any ideas?
