I think rubbers under the board hold the board(these rubbers prevent the board touch the panel). I had the same problem. After make sure you remove all screws, pull the board harder from one edge.

Philips TV, Model Number 50PFP5332D/37, the screen starts out all black, but then slowly the black starts to dissipate and the picture starts to come through. However, the picture is all gray & fu


You more than likely heard a pop noise when this failed, the infamous pop of death when the Y sustain module fails. First check the various fuses located on the Y and X sustain modules. If a fuse is open you have lost the large IC on either PC board. These boards are located left side 3 module and far right side module with ribbon cables attaching to display panel. This can be a complicated repair due to one of the buffer modules failing, The Y sustain will be identifies by Samsung drawing number LJ92-01200A, The Buffers are LJ-92-01202A, LJ92-01203A. This is most likely a job for a pro because 1 of or all 3 modules can be at fault. Some services on e-bay for these modules offer rebuilding the Y-main module and also testing the Y-buffers. If you want to DIY this TV this would be the best Idea, send three boards to a rebuilder on E-bay.

42 inch philips plasma tv model # 42PF7321D im pretty sure that one of my speakers are blown on the right bottom side it sounds really annoying i just want to know how i can fix it myself or how much it...


Here's the main support page for your unit in case you need the User manual or other documentation:

http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?slg=en&scy=us&ctn=42PF7321D/37

You may need ADOBE READER installed on your computer to read the USER MANUAL - PDF documents.
You can download this free at WWW.ADOBE.COM if necessary.
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there.

Assuming the warranty is expired, you should have no problem disassembling the unit enough to access the speakers with just a phillips screwdriver.

Normally you just lay the unit screen side down on a soft flat surface like a bed. Just make sure nothing will gouge or scratch the screen.

Then just remove screws for the stand and pull it off (see page 2 of the Online Owners Manual).

After that you can remove all the screws from the back panel and remove the plastic enclosure.

You should be able to access the speakers from there.
Here is a link to some spares from EBay:

http://shop.ebay.com/i.html?_nkw=Philips+plasma+speakers&_sacat=0&_odkw=42PF7321D%2F37&_osacat=0&_trksid=p3286.c0.m270.l1313



http://shop.ebay.com/i.html?_nkw=Phillips+tv+speakers&_sacat=0&_odkw=Phillips+speakers&_osacat=0&_trksid=p3286.c0.m270.l1313

I didn't actually see any speakers for your exact model, but the online selection changes constantly so you may just have to get lucky and spot one that will fit.

The other option is to just go into your MENU and turn the speakers off. Then just use the rear outputs to feed into a home stereo / home theatre system for your audio.

Please comment back here to this page if you have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.

If this was at all helpful please click on the 4 Thumbs Up helpfulness rating icon you see on this page.

Thank you very much and good luck.

Joe.

I have a Phillips 42in plasma 42PF7321D/37 when you turn tv on green light lights up you have sound and picture flickers a few times and then picture is fine and looks great. Noticed menus are hard to see...


I would certainly say the problem is in your power supply. Chances are real good that two capacitors are bad! You will have to remove the back cover...this is tedious and requires patience. You will be concerned with the board on the left side. You will have to remove the screws on the power board to lift it and see the top of this board. You should see at least one bulged capacitor. Replace, and you can bet the other next to it is bad. And another note..there may be a small cap at about 16volts at 10Mf that needs attention. These are clues and should help with repairs! Thanks for asking.

No power to my Phillips 42 inch Plasma 42pf7321d/37, just a red blinking light


Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.
Replacement boards can be found at a good price at Shopjimmy.com

It is pretty much a plug and play. It is more time consuming than any degree of difficulty.
You must make a strong mental note of where each screw goes.
Simply disconnect the Molex connectors and the screws on the Signal Board; you're pretty much reverse the process. No cutting or soldering is required!

Checking voltage on 42 in philips plasma


You're right. The YSUS board is gone. And most likely the Y SCAN UPPER & Y SCAN LOWER boards also gone. You need to replace these 3 boards. The original boards are from Samsung and you can get them from Samsung. The three boards may cost you US$400 more.

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.

Philips 42PF7220A/37 April 2006. Chassis Number BP2.3U


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.
