LG RU-52SZ51D 52" Rear Projection HDTV-Ready Television Questions & Answers
Tv shuts itself off
The power supply may be going on to protection mode. This is usualy because one of the scan amplifiers may have failed, or something is taking too much current and forcing the power supply to shut down.

Keeps turning off onto standby after 15seconds
The power supply protection is sensing a fault. Can be a problem on one of the boards or the power supply itself. The service rep will test by trying the boards with new ones; one at a time until the faulty one is located. He may start with the power supply board first. Once found he will leave the new board installed. Most of the time these boards are not serviceable at the component level. They use SMD high density design with multi layer boards.
Take care servicing these sets is fairly expensive. If the set is out of warranty it's a gamble if something else will fail shortly after.
