SOURCE: TV must be turned off and on 20 times before picture will stay on

you need to replace the audio/video apparatus. on the back of the tv you open the right side panel below and disconnect the thing looks like a transformer can't miss it plug it in and if the green light don't come on than it is burnt out, I took it to best buy and they checked it out and confirmed that it is burnt out. it is part that connects to the outlet. I am trying to find out how much it costs i did some months back just don't remember the price. So I am investigating on this where i can buy it cheap.

Runco TV turned on made a loud pop and now will not stay turned on


Capacitors blew most likely. Take it to a repair shop or learn to open and replace the caps yourself. Could be a fun project.
