SOURCE: won't power, light goes green 5-10 seconds later red flashing light

Solution Found.

I had the same problem with my 42FD5994. It was working fine, then one day I turned the TV on and the front light turned green for about 5 - 10 seconds and then the TV switched to protection mode (front green light is now red and flashing constantly). I did some research and found out the the power board is faulty. I ordered a DIY fix it kit on Ebay for around $55 (includes shipping). The kit contains 5 high temp capacitors and a new IC chip. It also comes with a good detailed photo of the circuit board the components that needed replacing.

I also spent $70 at Radio Shack for some soldering gear and went to work. It took me 3 hours to replace the 6 components. The IC chip was a pain to remove, but one that was out the rest went pretty smooth. I had to remove two extra blue capacitors in front of the IC chip to desolder some of the leads.

After I cleaned the board with Isopropal alcohol (99% pure) to remove the excess flux, I inspected the solder joints to make sure I didn't solder some runs together. All looked good.

Next I put the TV back together and hooked everything back up. I powered on the TV and the same problem as before. The TV went into protection mode. But this time I heard the speakers pop and the screen buzzed. So I pushed in the power button to reset the TV. Next, I turned the TV back on, but this time when the light was green, I quickly pushed the power button again to power off the TV. I tried the TV one last time. I powered the TV back on, and with the remote I turned the TV on. Viola! It worked. The TV powers on great, and works like a champ. I am guessing that the first time I tried to turn the TV on, the new components needed a minute to energize. I also started the TV cold, I should have plugged it in for a few minutes before I tried turning it on.

So, I was successful fixing my 42FD5594 with the DIY kit on Ebay. I ordered it from California. The company was great, and Everything arrived well protected. I figured if this didn't work, it was time to get a new TV anyway. I can save the $2000 for another day.

SOURCE: RED LIGHT BLINKS SEVEN TIMES

The most likely problem are two failed capacitors on the main board in the center of the TV The failed parts are easy to identify as the top of the cap will no longer be flat but will have bulged up. DO NOT attempt to remove the back of the TV unless you know what you are doing.
soldering on a circuit board will be required to fix this problem.

Replace the Main Power Supply inside the TV.

SOURCE: red light blinking, tv doesn't start

Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.

Switch the TV on: Press the power switch A on the front of the TV. A green indicator on the front of the TV lights up when the screen is on. If the indicator is red, press the

The green light blinks every time you press a key n the remote control.

Philips 42pf7621d/10 dead


One of the circuit boards should be replaced inside, probably the power supply, the good thing is that screen is ok and it's a most expansive part, you can take it to the local repair shop for diagnostic and repair.

I can't get my tv to turn on... nothing but blinking red light


Dont know if this will work for you or not, but my brother gave me his because of the same problem. It would power up and a green light would come on, then after 10 -15 seconds it would change to a red blinking light. I plugged a usb cable into the service port on the side and left the other end unplugged. Then plugged the tv back into the power. i took a small screwdriver and ran across the contacts in the end of the usb cable until both the red light and the green lights came on. I did this several times listening fot the clicking noises in the TV. after doing this for approx 20 seconds, i pressed the power button and the TV worked fine. 5 days now and no problems. Only thing I can think is I somehow reset the software and now it is working fine. Hope some of you can figure this out and give it a try. if the TV is just sitting, you have nothing to lose
