Sounds like the same problem I had when I picked up my LG 52SZ8R. After replacing the lamp the TV ran fine.

Easiest way to see if the lamp is the problem is to take it out, and look at the peice of wire in the globe as you would an old light globe.

If you need help, download the following manual, and look at page 9.

If it does come down to you needing to replace the ballast contact:
They should be able to give you a quote and part number, if you don't like their quote you can always use the part number to search for one thats cheaper.

Tv Turns on then stops after a few minutes

This set uses a lamp and a bad lamp will cause this symptom. You should be able to get the lamp out yourself and get a part # off it.

Call tech support! That's why these people get paid. Sites like this wouldn't need to exist if they did their jobs correctly!

WARNING...The ballast can output 3000volts when it initially fires the lamp. Without the proper test equipment you could injure or even kill yourself. You've verified that the lamp is good and now suspect the ballast?

The lamp is fine but....

The Lamp Ballast p/n 6316000009B could be bad if you already swapped out the lamp with a known good one as you can't tell by looking at them if they're bad. It may be worthwhile to have a technican look at this set as it would be an expensive mistake if the ballast is not bad.
