Customer Question
The screen flashes, 1/2...

The screen flashes, 1/2 second on 2 seconds off

Technician's Assistant: What's the brand and model number of your TV? How old is it?

LG, not sure of model, 55 inch, approximately 3 years old

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

I didn't think to try a different source, the screen doesn't stay on long enough to read any type of menu

Technician's Assistant: How long has this been an issue with your LG? What happened right before this?

Sunday night, it just started flashing

Technician's Assistant: Anything else you want the TV Expert to know before I connect you?

I have a LG TV 55LB5900, that screen flashes constantly, is this a common problem? Is there any way to fix it?
