Question about Philips 40pfl7705dv/f7 40 Hz 120 Led Tv - Philips
The tv only stays on for a few minutes then it just shut down by itself. Whenever that happens it loses all the settings. What is causing that to happen? Its a new tv.
If it is a new TV and under warranty, return it. There is an internal fault and it needs to be serviced.

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.
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
