LG 37" LCD HDTV.. 2 Months old. Red light blinks and thats it...

Well here's my problem. There was one time when my TV wasn't working. It wouldn't turn on. At that time the red light blinked for a second, then the green light for a second and that was it. If I unplugged it and plugged it back in right away the lights stayed off. If I unplugged it for 5 minutes and plugged it in the lights would blink again. I got it to work after 15 minutes or so. Not a clue how, but it worked. Well last week it did it again and it took me 2 hours to get it to work. I walked away to get a soda while it was plugged in and it turned on itself. Now I'm back to the problem again and instead of both lights blinking it only blinks red. And I can't get it on... Any ideas what the heck is going on?

It's 2 months old and I don't have a warranty. If worst comes to worst can I find a store with my TV and say it's only a week old and try to exchange it? I got it from Best Buy, but can I try to exchange it multiple places? They get there money back anyways when it's sent in. Let me know guys I'd be extremely greatful!

This is likely the power board. I have the same TV and I found that replacing the secondary caps on the board solved the problem. The caps that are blown are indicated by an expansion of the cross on their tops. Replace them with the same part or higher voltage rating can fix this problem for a time until they blow again. The power board is likely under engineered for the TV's power requirements. Note that if the TV turns off completely then likely caps are blown in the primary section or even the regulators.

As long as you have the bill of sale, then you have coverage for the first year from the manufacturer. That's normal coverage with BestBuy.

My LG 37LG50 TV wont turn on ?

Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.

Red/green light keeps blinking.

This issue is related to a bad/failed power supply inside your TV.

Call LG to see if your TV is still in warranty. 800-243-0000

If not in warranty, the power supply is about $225.

Good luck. I do hope that I have helped you.

Red blinking light when tv is turned off

You can't fix it. There is a bad board in this set; either the main board or the power supply board. You'll have to call a professional.

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

LG 42 LCD no sound or picture

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

Blinking power and OPC lights

If you have tried to reset the TV by unplugging it for 2 minutes and still have the same issue then it is time to bring the set to a repair shop.

Polaroid has a 1 year manufacturers in-home warranty on 32+ inch TV's. Contact them and they should send someone to fix the TV for you.

Since it is still under warranty make it Polaroids "problem"

hope that helps!

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

You might consider using Best Buy's "Geek Squad" just to make sure the set is not a dud.   I'm sure if it's near to the 30 days, they would be real schmucks not to replace it.   But, maybe it's just a setting somewhere in a menu.  Have a good look at the manual with a beer, and I'm sure you will find something useful.
Good luck.
