Customer Question
I have an LG55LS5700...

I have an LG55LS5700, circa 2012. The screen adn sound have died, the power light blins 3 times, stutters and resatrts the blinkinng sequence. I have replaced the power board byt that did not resolve the issue.

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

See above

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

There is no picture and no sound, nothing appears on the screen.

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

Nothing of consequence occurred before he proble emerged.

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

I changed the power control board.
