TV wont turn on and sometimes I can get it to work for a few hours, but it shuts itself off and red light starts blinking. Maybe power supply is what I was told. The one year warranty was a week overdue when this happened. When it turns on the picture looks like brand new. What do I need to replace?
No one can tell you what will fix the set---I would suspect the power board but it can and could be another board--some tests are needed and if you are not able to do them you either have to start guessing or have a expert examine the set---in the end they will have to guess also but it will be an educated guess.

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.

Whe you press the power button the TV led have to blink several times and the it have to change to blue, meaning Tv is on.
If you press the power button and the led start blinking and goes off, then you need to replace the mainboard because it is damaged.
Bye
