    thank you for answering yes i replaced all 4 and they are direct replacements all numbers match on the caps 1000uf 16v 105c only difference is different brand and taller i double checked the polarity while i was doing it and again now it's marked on the board pos and neg and the caps have the same neg stripe down the side as the old ones.i can't find any wires off anywhere and the first time i set the board it didn't power up and i had to reseat it by leaving the case loose and seating the board by itself then sliding the case the rest of the way down that made it power up but i get no picture just a fer color lines and none of the controls work accept on and off and it shuts down after a couple minutes on it's own. i am very new at this never worked on a tv before so any advice i get is very helpful i had a repair man out he said it had a bad digital board had to be replaced not available is it possible he moved wire plugs while working on it some of the plugs look the same in there but they are all plugged in as i found it thanks again for the help.

    don't know how to get a picture on this but i'll do my best to describe it the screen after it turned on had thin wavy lines going horizontaly acrss the screen all three colors like threads in a wave pattern hard to see not bright weaving into each other if i did take a picture you would never see them too dark a screen the bulbs inside the set were flickering when it was on i'm not sure what you want to see on the dm board i'll try to get a pic on here if you can tell me what you want to see thank you very much for the help.

    the repairman did open the front of the set i don't know what he did i know he never opend the dm board he just said it was bad there are plugs inside empty next to ones with plugs in them i didn't unplug anything but is it possible the repair guy tried different spots for the plugs? and i really really appreciate this tim i can't afford a new set or another hundred buck for some guy to tell me it's shot throw it out i never worked on a tv before in my life but when i read about all the people on here with the same problem it was worth a shot and i do have power now just no picture thanks so much.

Did you replace all 4 caps in the board? And did you put them in with the correct polarity? Also check to make sure that no wires came loose durring the repair and that you got the dm seated back in the tv right. Also what size caps did you put in?

    Can you post a picture of what you are seeing on the screen and a picture of the top and bottom of the board where you were soldering? If you cannot get pictures then please describe the lines you are seeing in as much detail as possible, are they vertical or horizontal? what color are they? where are they on the screen. Let me know so i can help you?

    Ok you have retrace in all three tubes, at this point we need to be carefull, we dont want to damage your set. Either there is a cable unpluged or someone turned up all the screen controls. Did either you or the repairman open the front of the set? If noone opend the front of the set then you must have the 200v line unpluged. Let me know about opening the front of the set, and in the meantime I will pull a manual and find the 200V line plug.

    Ok well hopefully he turned up the screen controls. Take off the front of the set and look at the black box with 6 control knobs on it. this is called the focus block, look closely at it with a flashlight to see what 3 are for focus and what 3 are for screen. (the top 3 should be screen and the bottom 3 should be focus if im not mistaken). turn all 3 screen controls counter-clockwise as far as they will go then turn the set on and let me know what happens

  • experttv
    experttv Sep 11, 2008

    ok, now we are getting somewhere...I want you to turn it on and slowly turn up each screen one at a time untill you get those lines, then back it off untill you dont see the lines again then go 1/4 turn furthur. Do this for all 3 screen controls and let me know if you have a picture or not (if you dont have a signal hooked up to the tv you can just press the menue button and let me know if that shows up.

    Ok looking from the back there are 3 big boards in the bottom of the tv. We want to look for the one on the right and look for a cabel labeled PM it should have 7 or 8 wires in it. and should run up to the little board hanging off of the red tube. That set should shut off with no signal after a few mins dont be to worried about that as long as it comes right back on. We need to make sure that PM is pluged in on both ends

  • experttv
    experttv Sep 12, 2008

    Sm and SP are pluged in as well? At this point do you know how to use a meter? Give me a call if you like 904-885-2203

    Try taking the dm out and putting it back in let make sure that its connecting on all pins. also if you can send me some picture of the work you did on the board that would be good.

Thats a very common problem caused by weak caps on the DM board when power is lost they drain and then cannot recharge when the power is restored the WS55511 DM repair kit from www.tvrepairworld.com will usually solve that issue. The kit contains the caps and the cd with instructions.

You have to replace the faulty capacitors on the DM Board.. Even if you have some experience in electronics a service manual should prove very handy.. Its got full schematics and how to guides so that if you just have minimum knowledge about using a multimeter you can fix it yourself..

The red standby/power light blinks and the tv screen is blank. Could this be the bulb?


I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)


2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

The 3 blinks on this model TV means you have a lamp cover error. When you install the cover look at the tab on the cover and make sure it is making contact with the micro switch inside the lamp housing.

1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). 5. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 6. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 7. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001
