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.

SOURCE: Red light flashing

ctf1800,

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.

SOURCE: Philips 50 Inch Plasma Model 50PF7320A/37 will not turn on

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.

Power cycles, wont turn on.


Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Power Cycles


Most likely A power supply problem, you can try unplugging the cord waiting 3 minutes and retrying, to see, if not the open the back and see if the caps are in good condition, even though it did this last year, could be more a problem now since last 1.5 years ago its was something else. If you don't know how to solder then time to call a repairman.

Hdmi ports are not working


Have you gone to the philip's website. There is a firmware upgrade available. Simple to install if your tv turns on. You just need a USB drive to load the software on.

Sounds like you either have a defective LCD panel, LCD panel tab connection, or a LCD to T-con faulty connection. Does tapping or squeezing the left side of the TV change anything?
