SOURCE: Philips 42" Flat Screen Plasma - blinking red light 7 times - HELP please!

I had the same issue with 2 of these sets. It ended up being 2 capacitors were bad on the power supply. They are located towards the bottom of the board, you can visually see they were buldging and leaking slightly. I replaced them with 2 I salvaged out of an old computer (of same values) and the tv works as it did before.

SOURCE: Red LED blinking after turn on the TV (Philips Plasma 42PF9631D

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try
