50" LG Plasma TV issues

[vortalexfan]

Hello Everyone a friend of mine gave me their old (from 2012) 50" LG Plasma Smart TV model 50PM6700 that when you go to turn it on it clicks on like its going to power on and you get a grey colored screen for about two seconds with a flashing red light and then the TV just clicks back off with a steady burning red light again.

I had looked up the symptoms online and one forum said that the power supply board had an issue with C802 on the board and that replacing that capacitor fixed the problem for most people and some people it didn't.

I was wondering if anyone else on here had a similar experience with a similar TV and had any ideas as to what would cause these aforementioned symptoms.

Thanks.
