Customer Question

I have no picture or sound. We just got back in town and I understand there was a lot of lightning while we were gone. The power strip it was plugged into was shut off, so I'm not sure if it was lightning or not.
JA: What's the model number of your TV? How old is it?
Customer: 42LN5700-UH. I think we purchased it in 2014
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?
Customer: the only thing that comes on is the red light in the front
JA: How long has this been an issue? What happened right before this popped up?
Customer: the tv has not been used since May. It is in a seasonal use condominium
JA: Anything else you want the TV expert to know before I connect you?
Customer: not that I can think of

Sorry you are having trouble here, you have by-passed the power-strip and gone directly to the wall with TV plug just to eliminate the strip?


Customer: replied 1 year ago.
no difference. the red light still goes on and off, but no message or other info on the screen, and no sound.
Expert:  Anthony_Infotech replied 1 year ago.

So the power-light is blinking red, that would mean likely the power or more likely the mainboard has took a hit maybe you did have a lightening strike?either way if you have rebooted the set and its still the same it is a hardware issue likely to be the main-board do you think you can replace this board yourself?

I will provide all the info to do that let me know.

If you are not comfortable doing that you will need a tech will locate a tech in your area

Let meknow if you can do this or need more info.
