My lg 60lb7100-ut tv...

My lg 60lb7100-ut tv is doing the following: when I turn the power on, the red power light comes on, the screen flashes on then off. After the screen goes off, the red power light flashes 3 times and goes out. can this be the power board failing and needing replaced?

Technician's Assistant: Are there any HDMI cables or A/V jacks (red, yellow, and white cables) plugged into your 60LB7100?

Nothing is plugged in. All cables disconnected

Technician's Assistant: Was there a power outage recently?

No power surge that I'm aware of

Thank you, ***** ***** a typical symptom for this unit when

1 or more back light strips fail within the back light system of the LCD panel, How can I help are you going to attempt to repair this yourself?

Customer reply replied 3 months ago
I might attempt the repair. I have located the power board and tv board, Not sure where the LCD panel is
TV Technician: Steven, Technician replied 3 months ago

Okay its not going to be a power board or main, if your not sure where the LCD panel is I"m thinking this might be a bit over your head but I can get you going in the right direction? you will first have to check voltages on the power supply to confirm back light voltage to backlights do you have a digital meter and are you capable of working with live voltage in excess of 200 volts?

Customer reply replied 3 months ago
Thank you for your time. I will research some more and learn more about the LCD panel
TV Technician: Steven, Technician replied 3 months ago

Okay you can always post back for more information if you wish? Their are several videos on you tube about replacing back lights.

Just so you know, it was the power supply board.
TV Technician: Steven, Technician replied 3 months ago

Thanks for the update, this is why I said above you would need to to test voltages to confirm the power supply or panel failure. You didn't answer if you were capable of doing that or not. but im glad it was simple enough for you to fix yourself.
