Question about LG DU-37LZ30 37 in. LCD HDTV

1 Answer

My 2 month old 37" LG HDTV won't turn on...

Alright guys first off I'm not stupid. The TV is plugged in. When I plug in the power cord into the tv the red lights (Bottom right of the TV) blinks for about a second and the green light then blinks for about half a second. Most of the time however the lights don't even blink. They only blink when its been unplugged for about 20 seconds. Even then sometimes it doesn't blink. However after that the still doesn't work and I can't do anything. This happened once before however the TV actually stayed powered after a few minutes. I've now been trying for hours and this stupid EXPENSIVE TWO MONTH old computer won't work. I don't know what to do. I bought it from Best Buy, but it's passed the 30 days and I don't have a warranty. Any help would be greatly appreciated.

    I finally got it to turn on however I did nothing. I left it off and it
    finally clicked on 5 minutes later. What do you think might be the
    problem? Could it be some weird overheating or something?...

    ours has been doing the same thing! at first we thought it was a problem with the remote, but when the tv wouldn't respond to the manual buttons on the unit we knew we had a problem. any solutions other than returning it?

    I just bought my lg plasma yesterday and today while watching it, it turned off by itself. Now it won't turn back on... Is this a defect in the tv. Should I take it back while I can and get a different brand? Or keep it and hope the manufacturer fixes it correctly?

    I had the same problem, after a week of owning the tv it just turned itself off, when you switched it back on it stayed on for about 10 seconds the switched itself off again. Solved the problem by sending it back, got a replacement which has been fine.

SOURCE: My 2 month old 37" LG HDTV won't turn on...

I called my local Best Buy for our LG 37" and let me just put it nicely that I am no longer a customer of Best Buy after 8 years of patroning... Ours is 5 months old and still under the manufacturers 1 year warranty. After 2 hours of talk time to those "people" at Best Buy, I called LG USA directly (1-800-243-0000) and they are sending out a tech to repair whatever is causing ours to turn off by itself and not power up. This will be covered under the 1 year warranty and all I have to supply is the receipt to the repair tech. Hopefully, things will go well since I have now move on from the inept abilities of Best Buy. LG warranty is a nice alternative to paying The Geek Squad for sure.
