Question about Philips 42PF7220A 42 in. Plasma Television

Philips 42PF7220A 42 in. Plasma

TV will work for about 4 minutes, then it will turn off. The green light (power on light) goes off. Then a red light flashes on 5 times in a row, then pauses and repeats. While this is going on, I hear clicking sounds inside the TV like its turning itself on and off.

Philips tech support said it had to do with a power source problem but to be sure, take it to a Philips authorized dealer. I called 2 and they said I was looking at $950 to fix it.

I took out the fuses and tested them, they were all good. Is there a part I can replace?

I had a Similar problem where I would turn the tv on and the green light would come on and then the red would follow and blink 7 times. I tried unplugging it and then then replugging it back and it would still do the same. What I did last night was that I unplugged it and then replugged it back, when I saw the green light, I would unplug it again, till the light went out and replugged it, I did that 3 times in a row, and waiting and it came back on. Hope that works. I still don't know what caused the problem to begin with..

If you know how to circuit test or at least check components for tolerances then check your power supply board starting with all the diodes and capacitors you can find. I think that noise you can hear is a faulty capacitor. Please remeber to discharge all capacitors before you work on anything because at worse it could end up seriously injuring you at best it WILL fry other parts of your tv. Good luck.

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.

Philips 42PF7220A/37 Chassis Number BP2.3U


I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.

Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.

After you remove the back cover inspect the power supply board for swollen or bulging capacitors. Pull and check any capacitors that you suspect to be swollen. Next, look for a sticker in the upper right hand side of the TV set. Use the values you find on the sticker to calibrate the voltages on the power supply board.
