Question about Philips 42PF7220A 42 in. Plasma Television
My TV started to act funky when I turned it on a couple of months ago. It makes a cutting in & out squeaky noise with the sound and the picture cuts on & off until it seems like it catches itself and gets warmed up. The problem has gotten worse and now the tv will cut off and a blinkging red LED will come on the front of the tv. It blinks 6 slow blinks then 3 fast blinks. If I unplug the tv for a minute and plug it back in it seems to reset it and sometimes I get it to turn back on, but it does do the cutting in & out thing. What seems to be the problem, is there a code book for the way the LED is blinking to know what is wrong, is it something I can fix myself?
Unfortunately, the only way to Reset the TV is to keep it unplugged for Few Minutes.You actually did this many times, However, it would still never solved the Problem.This is an Internal Failure which needs you to Open the TV and check Components. If you have tools like Multimeter and experience, i would be glad to assist you .
You would need Schematics as well. So, we could also get that from a Service Manual. Make sure that you need to do the Repair perfectly as a small mistake could Damage the TV.
Let me know,if needed further assistance,
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

This particular blinking code usually signifies a pair of capacitors, 3300 uf 10 V, that are located on the power supply board. A visual inspection usually shows that the tops of the capacitors are bulging. If the caps are the problem I would strongly advise that they be replaced with a better grade of capacitors.Once this is done you will also want to ensure that you have the latest firmware upgrade from the Phillips website. If you have the experience and the tools to do the repair yourself you will want to set aside a bit of extra time as the power board is well buried inside. If you are going to have to pay a repair shop to resolve the issue you should have them give you an estimate first. Unfortunately this can be an expensive repair because of the difficulties in getting to the board. With the price of flat panels dropping over the last couple of years the cost of replacing the TV may almost equal the cost of the repair.
Good luck and thank you for allowing us to help identify your issue.

Thanks for using FixYa. It is due to the high voltage shutdown which might be exceeded 33k and the unit shuts it self down to protect other parts being damaged. Also please check power supply regulation and horizontal circuits. If these are fine then it means Small Signal Board has gone bad. You’ll need to replace Small Signal Board. It will cost around $300+. As this board requires special set up, you’ll need to contact a qualified TV repair tech. Please do accept the solution if the issue is resolved or post a comment for further assistance.
