42" philips plasma, black screen and flashing red light

This fix was posted on similar problem, worthy of repeating: Replaced 3300mf 10V capacitors at PS. Both had bulged slightly. Upsized to 25V as the previous solution poster had suggested 16V but I could not locate 16V so used 25V and TV is back to normal!

The TV normally has a green light illuminated in the lower left. Now there is a red blinking light (7 times) and the TV is not responding to any TV buttons or remote commands. If I unplug and plug back in,...

Philips Televisions are legendary for having faulty power supply capacitors.

In order to prevent really bad things from happening, the TV does a two-stage power-on. It first does a basic diagnostic test, and if that fails, it stops it from going any further.

Philips tends to use cheap capacitors, use capacitors that are somewhat under-sized for the job, and also seems to be pretty bad at soldering.

Personally I've got my Philips LCD TV opened up on my workbench for that exact problem.

Most repair shops would replace the whole power supply board ($150-200 part plus labor), while most DIY fixers take a stab at replacing the obviously bulging and failed caps for less than $10.

I have a Philips 50" Flat HDTV model 50PF9431D/37. Problem with screen turning on. I get sound. I get 9 quick flashes in red. Then after unplugging and plugging back in several times. It then blinks...

I have the exact same problem! I have it hooked up to a power strip now to unplug it by flicking of the power strip and waiting for the red light to go out then I turn it back on while Channeling up 10 X's and then down and up until it comes on. I listen to the sound of the switch which it comes on. I turn it off if it is faint and then back on and channel up. Crazy process but it's been working. It takes about 10 minutes everytime to get the TV on until I get a tech to come out and look at it. The capacitor keeps a charge which is why the light is flashing with a code for 60 seconds./JJ

Red light on my Philips tv goes 7 times

It's basically a common problem with all brands of flat panel TVs. Heat is the biggest enemy for circuit boards. And the flat panel TV generates a lot of heat.
The most common part to fail is the power supply board (Backlight Inverter Board) for the screen or the Main Power Supply Board for the TV itself. The flashing 7 times is a code for a technician look at a certain circuit path for the malfunction.
If you have some electronic experience and you want to repair it yourself, you can sometimes find a Service Manual over the internet for less than $20. It will have red light flashing codes, diagrams, schematics, and part number list. Cheaper than buying a new TV. :)

Tv won't come one and blinks red 7 times then stops.

When the bottom half of the picture goes out this usually indicates a failure of the lower Y driver module. When this module fails it will often take out the Y sustain module and when that happens the set goes into over current shut down. Both boards will have to be replaced. All of this is assuming you have a Plasma set and not a LCD flat panel.

7 red flashing lights, won't power up..

Check the power board for capacitors with the tops bulged up. They are 3300uf 10v. There are either 2 or 4 of them depending on your set.
