It will be best to replace the power supply regulator board as card basis.

Look in the manual. (Page 4)

Turn the TV on From main supply: Ensure that the main supply is turned on. A blue indicator light on the front of the TV lights up. When the TV is turned on by the main supply, the blue indicator light will blink for 45 seconds. This is the lamp's start-up period. When the light goes off, press the POWER button on the remote control or power switch. Press POWER to turn on the TV.

hi,
You have to check the power supply of you tv for any voltage missing. also check the back light inverter board for any short circuit in it. Inverter transformers in the back light controlling board can become faulty.Three blink indicate the power supply have some problem. First of all replace all the electrolytic capacitors in the power supply board. If filter capacitors in the power supply is bad then this problem can occur.
ok

The TV needs to be connected to its tuner box in order for it to fire up properly. In fact, with the TV in standby (red light), by switching on the tuner box a control signal is sent up the cable and the TV switches on fully.

that means that the phone needs to be unlock by the network provider

yes it is due to dry solder in vedeo driver section(a board fixed to the pict-tube.).

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.

this tv is exchange model through philips. no parts available. contact philips at 1-888-philips for in warranty or out of warranty information

Hey habo,

The red light you are referring to most likely is the power indicator light. On many newer TV's this light will appear red when the TV is off or in "standby" mode, and green when the TV is in operation.

Please keep in mind that some TV models may use the power indicator light to notify owners of ay potential hardware problems as well, so you may wish to refer to your owner's manual documentation if you have been encountering any problems during TV operation.

Hope this helps you out.

Sincerely,
Aaron
