Question about Philips Televison & Video
Just a fraction of a second of red light, turns to blue but never comes on. instead it cycles off and on repeatedly
Power supply, check for back caps, remove backing and check for bad bugling caps, if you know how to solder then its might be a fun project to do, if not time for a repairman call or take it to a shop!

These Polaroid LCD sets all fail like this. Bad power supplies. Call the warranty number and demand to have the main module replaced even if it is out of warranty.

I would love to have that service manual. My Philips 37PF7320A died 4 days ago with the typical 1-4 blinking lights. The fuses are fine but I found a 100 ohm 1/4 w resistor that was dead and replaced it, but no change. Now I have looked closer at the "dead" resistor and after the brown-black-brown and there is a poorly applied green band before the gold one, so I'm not sure what I have. I guess I need to get a high resistance tester off eBay.

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

Here is a photo of the board where I have removed the two from my TV. You can see the two open holes.
