I have a 3 year old "LG" 37LG50 flat screen TV which I bought for the great 1080P picture quality, the styling and price. A few months ago it started flashing the channel menu on the top of the screen and the tuner became unresponsive. I called customer service and they gave me some instructions. I changed the remote control batteries and unplugged the set in an attempt to reboot it. The problem persists.

I've noticed in my Google searches that this model has had problems with the power supply and tuner. Paying a lot of money for a service call and a new tuner board doesn't sound like a great idea. Any suggestions?

You might want to remove your e-mail address. Spam bots will comb the Internet and grab e-mail addresses to add to spam lists.

That being said, you could use an external tuner box (like a cable box) in order to bypass the TV's internal tuner.

The problems with the power supply on that unit is the common capacitor problem. It should be a fairly inexpensive fix and if you have electronics knowledge/experience is something you could do yourself.

I find the Capacitors in the Power Supplies a problem as well.

OP: I cannot stress enough that you need to be careful if you decide to attempt any repairs on your own. Damage to your TV is not the worst thing you have to be concerned with should you be unsuccessful in any repair attempts--worst case scenario is harm to yourself.
