Technician's Assistant: What's the make and model of your tv, and has turning it on been a problem in the past?

The make is LG and the model number is ***** yes, we bought it used and turning it on has always been a problem

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

Yes once, I have the input in correctly, the menu works...I have only tried HDMI1

Technician's Assistant: How long has this been an issue? What happened right before this popped up?

Nothing...we just bought it used, and this has been an issue from the beginning
