TCL Google TV shows logo and then goes to black screen
TCL 55C805 just over 2 years old (no more warranty) turns on, shows TCL logo or main screen for a second and then TV goes black. Sometimes not in full brightness.
I've tried disconnecting everything except the power cord. Tried power cycling, leaving it disconnected for a few hours.
Can I try something else to make sure it's the screen failing and not something I could fix like the mainboard or power supply?
Thank you for any suggestions
