You are not the only one I can tell you that. 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

Philips TV won't come on or goes on and off. FIX IT HERE....Lay Philips 42" Model 42pfl7403d/27 TV down on a blanket or carpet so not to scratch the front. Use T-10 torx driver to remove all screws from the back. Look at power board on left center of chassis, and you will see swollen capacitors. I found three such capacitors on the power board, but I also made a list of all the values of the other capacitors just for future reference sake. There were about 21 capacitors and if you had to replace them all you are talking about $2.50 apiece which is reasonable. Use a 20 to 40 watt soldering iron from Radio Shack , not a soldering GUN which has too much heat. I wrote down voltage and micro-farad (uf) values and purchased three new capacitors. Remove screws and few plug-on connectors from power board, then lift off the board from the chassis. Unsolder old capacitors keeping track of what hole negative capacitor lead goes to. Solder-in new capacitors making sure polarity is correct. Put TV back together and turn it on! This was a $7.29 cent fix I just completed on my mothers Philips HDTV. Time about two hours.

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself


Mine was doing the same thing. Update the firmware and it fixes the problem. Updating the firmware is done by downloading the file to a thumb-drive from the phillips product support page then plugging in the drive into the side of your television and turning it on. See your manual for slightly better instructions.

Westinghouse 1080P 42" LCD TV - HDMI stopped working


I know this is late, but this happens frequently. If anyone else has the same problem try unplugging the TV for 60 seconds. Plug it back in and then hold the power button down for 30 seconds. That will reset the TV.
You should see the Westinghouse logo come up and the HDMI should work. This has happened twice with my TV in 1 year.

No picture or sound just six red blinking lights


Use your warranty in a hurry before it expires. Your TV when into protection mode to prevent further damage. Most TVs have a 1 year warranty. Good Luck.
