Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Initially, have you tried unplugging the TV for an extended period of time?
The idea is to simulate a soft RESET and dissipate residual power.
Then it would be an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter (and even perhaps a soldering iron)?
