Philips Plasma 42PF7220A/37 won't come on, the red light blinks 4 times over and over again. i have replaced 2 capacitors that seem to help solve this problem for some people, but I just saw on a post from Fixya User DANIEL719, where he told someone else that........ if it is a 5 blink code replace Crystal 1h00 On Ssb new part number is 24225430 1397...... i have 4 blinks.... where is the SSB? what is a crystal? Daniel seemed pretty confident, this would be great if it worked. If i could somehow email DANIEL719 that would be great. thanks, stephen

    I can not believe what i just read.  You simply copied a previous thread's text and tried to pawn it off as actual experiential knowledge of your own just to hopefully cash in on a quick dollar.  I will be sending an email off to whomever to complain about this.  this is disgraceful.  hopefully another of your peers with actual knowledge, who doesn't want to rip me off might help me. 


    I already had read that information on here, heating and cooling have done nothing for me.  I am attaching the other thread's text so that you know i am serious ans know what i am talking about.

    After a lot of research, I have been able to locate the part which in my Philips 42PF7220A/37 Plasma TV appears to be the problem. I found out that heating and cooling certain parts of the board(s) allowed me to get beyond the 5 flashes error message and power up the TV. Through a process of elimination, I narrowed it down to the SSB Tuner board 3104-313-60376, This board is located behind the board covered with the shield. The specific component in question is the one I have circled in red on the attached photo. It is a crystal Xtal 27 mHZ 18Pf PART# 2422-543-01397. When I spray this component with cold air (freeeze) for a couple of seconds and then plug the power back in the TV will go through it's initialization cycle and turn on. It may turn off automatically, in which case, you just power it back on either manually or with the remote. It has now been 7 days, and it hasn't failed since. I have NOT replaced the part, if it fails again, that will be my next step. The part is about $ 10.00. The entire card can be purchased for about $ 100.-
    I am reluctant to do anything further, because I'm not positive that the component is the problem or possibly the input to it. What I do understand is that a crystal can be excited (turned on) by either heat or cold. Perhaps it was stuck and spraying it with cold and heat released it...."
    unbelievable!

    Now you are 0 for 2!  I don't even have those capacitors on my board.  Why don't you actually do some research before you just find something floating around on the internet and repost it.  Those capacitors are on a different Philips board.

    any other experts want to help.......

    i have been to the AVS Forum and already read the thread you copied from.  The guy that listed capacitors 8020 & 8084 simply said that they kind of looked different, but that "maybe i'm just an amateur."  He never even tried those or posted results.


    I would rather not get any advice at all rather than people just grabbing **** off the internet and saying stuff like ... " it has been noted that...".  I already replaced capacitors 8059 & 8060 a week ago.


    Also, I like how you used a pic from AVFORUMS.com, but copied your info from AVSFORUMS.com.  


    anyone? no more BS please.  Actual knowledge would be preferred!

Can you possibly measure the voltages on the tuner?, it should have +12v, a voltage from 1 to 33v, a voltage of 5v, try to write it down cause it maybe a minimum of six terminals

    i would also suggest start measuring the 12v source of the tuner as i have mention on my first post, have a multimeter pinned on that supply line, hope this help

Your TV has a problem in the power supply section. Capacitors (particularly C8059 and C8060) need to be checked and also multiple bad connections in the power supply board need to be resoldered.but in many cases it has been noticed that this capacitors looks finwe but the power supply board goes faulty due to short tracking in the circuit.so whole power supply board has to be replaced.a couple of the four larger caps running from top to bottom on the left side -- specifically the two at the bottom -- look a tiny bit different from the others. They say 47uf 350v, and appear to be 8020 and 8084.can also be faulty.Also make sure you install the negative side of the capacitor to the negative side of the board and positive to positive.
as what you are saying 4 blinks.this power supply board fault is the reason for 4 blinks.
to see how the board looks click the link

to remove the board and replace with new board -----The board has like 8 screws and I think it was 7 connectors plugged into it, just remember to mark the cables before unplugging.

thanks.keep updated.

    Hi,



    I appologise for this coincident of duplicate solution. This was pulled out from the same database and resulted in duplicacy. Since you have already done the steps with no resolution I would suggest Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixi...
    for more detail.


    Thanks and it would be my pleasure to resolve the issue which brings more statisfaction then monetary benifits.



    Thanks once again to bring this to our notice.

Tv will not come on. Red light blinking on bottom left front. Red light blinks 7 times


I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.comj

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.

I own a Philips 42PF7220A/37 42'' TV (LED flashes red, some people on the net say its the capacitor c2074 to be replaced with a 2200uf 35v. for some reason i cant seem to find that capacitor number. can...


Most likely the problem is your Philips 42PF7220A/37, may not have the same power supply board as other people are talking about on the net. So, the C2074 capacitor maybe under a different number.
The best thing I would do if I had the same problem is to get a Service Manual on the internet. It cost about less than $20. Right now your TV is in " Protection Mode" and blinking a trouble code with the red light. The Service Manual will tell you what the red light blinking code means. Plus, it will give you schematics, part numbers list, and test point for diagnosing. It's better to have a manual for fixing than going by guesses over the internet.

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.

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.
