I read what one blog posted by Doug Mohr and started out by examining the power cord and UPS. The set had been plugged into a power supply that either provides surge protection or surge protection plus battery back up.

I changed the power cord connection from surge protection and battery back up to surge protection only. It has been two days since making this change and the problem has evaporated. I intend to change the power cord as well.

If the problem comes back I will go deeper down the path others have taken before me and change out the two capacitors with 3300 uF at 25 volts,105C.Capicitors only display a problem that is up stream. However, if the board was under designed this change from 10 volt to 25 volt and high temperature capacitors will solve the problem, or fry a down stream component.

With FPL I have no options

Philips 37PF7320A/37 won't turn on


That blinking led is an error code for the audio standby board in the set. It should not go out this soon and yes it should last longer.

Blinking red lights


If your TV is less then a year old, i would suggest to call the vendor or manufacturer to have the LCD repair under warranty. Most electronics devices carry one year warranty.
The failure of your LCD is not related to any fuse since you're still getting some lights from it.
Good Luck.

I have a problem with my WD 52525


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
