Unit turns itself off and back on again after several seconds. happens repeatedly. sometimes will return on, sometimes I must use the remote to power back up.
Sounds like a loose contact at its main power regulator board. Contact any service technician. Gopakumar Gopalan Google

Take the Inverter Board out and check for Open windings on the 6 Transformers along the edge of the board. When you find one open, get the number off of the Transformer, Google it, buy one and replace the bad transformer. I was given one of these TV's and fixed it for $11. It's not rocket science, if you can use a DMM and a soldering Iron, you can fix this.

Hmmmmm.......My ratings are slipping so this will require a serious answer! The solution I will give you will be of most accuracy. Your power supply startup resistors are are bad. These are located on the inverter board. Replace the inverter board or if you are up to it replace R603,604, and 605 with 390K quarter watt resistors. If the values are different or the same as mentioned, use the values I just told you! If they look fine or test fine...replace them with the value just mentioned!!!!!! Anyway!!!!!! Take this info to a TV tech and show him your answer. Thanks for asking me!

I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
Hope this helps
