    Yup I have the same issue... isn't funny how HP admits to having used some SUB STANDARD parts in this model but refuses to fix the issue if your set doesn't fall with in their "free fix" serial range?

  • pwvogel2 Dec 12, 2008

    I had the "Mal Discharge" problem with my with my HP PL4260N for about 1 year when I found out HP had extended to warranty on the Digital Controller board so I had it replaced. 6 Weeks ago. It cured the "Mal Discharge" and the pictured looked great. About 5 weeks after the new board was installed there was a snap and now there is sound by no picture. HP shipped a new Digital Controller board and the repairmen put it in today. It did not fix the problem he said it is probably the Y board. First, could these have been related? Second, I saw how her replaced the boards and see not reason I can't replace the Y boards. I have built several home computers. Anybody know why I shouldn't try?

    my 42 in hp plasma has sound but no pic ...ive called and called but they refuse to fix it .....any 1 have an email addy to some1 that could possibly care about the problem i am having

  • Anonymous Mar 20, 2009

    I called the number above today and after talking with the case manager HP said that there was nothing they could do. It's not right that they put a defective part in their product and won't stand by it after it fails. Is there a class action lawsuit regarding this matter???

  • StanHatfield Mar 22, 2009

    Same issue "mal discharge" HP tech told me that since I did not accept HP's other promotions I was not notified of the extended warranty. Class action lawsuit is the only way I am gonna get this TV fixed! HP is out of the TV business and could care less about this issue. I could pay a 1 time service contract for $700.00 and "maybe they could fix it" I can buy a new set for $700.00. Watch for me dragging this set down the street on the back of my truck on You Tube. Oh and HP, never again!

  • eaune Mar 23, 2009

    I have the same freakin' problem as the rest us that have this **** TV. I'm livid right now and damn pissed I bought this POS.

    If there is actually a class action suit I'd like to join it. This is a sd case of customer support and at this point they lost any interest that I may have had in buying ANY product that they offer.


  • dobles5 Mar 25, 2009

    I'm just joining this thread--my HP PL4260N was working fine (it's about 2.5 years old) until this evening. We were watching TV when suddenly the screen went blank, although sound was fine. The TV powers on and off without a problem (the on/off button clicks and changes color) but the screen is entirely blank. Even the HP logo that normally comes up on the screen is absent...it's just dead. Is this what you've all experienced?

    It sounds like we're out of luck, because our warranty is no longer in effect, but I thought I'd check to see if this really is a common problem.

  • mslawson_20 Apr 08, 2009

    My TV just went out the other day as well. I called the number you guys said to call and she won't help at all. Says I have to pay the $695 dollars or call technical service. I will never buy another HP product of any kind again.

  • kkdtpsully Apr 09, 2009

    REPLACED THE Y SUS AND THE Z SUS AND THE SCREEN LIT UP BUT NO TV OR MENU? ANY CLUE WHAT ELSE COULD BE WRONG?



    THANKS

  • phimoore Apr 13, 2009

    I am having the same issue with my pl4260n that many other people are having. I get sound through the speakers but no picture. Not even the OSD. Right now it's a $1300 paperweight.

    Also, I tried calling the HP Case Managers Line 877-917-4380 ext. 79 but it didn't help. Both times I called that number they said my TV was out of warranty and it would cost $629 for a technician to come out and fix it.

    Any ideas on how I can get this fixed/replaced?

    -Phil

    I have the opposite problem and need new speakers for this tv. Mine are acting up. Does anyone with a defunct tv have a set of speakers that they would like to donate?

    I have exactly the same problem which is being described by many who have posted here......my set powers up but no picture, a totally black screen. I get a click sound immediately after the on/off button shows a red color, then it becomes rather purple or a portion of it is blue. Then I hear another click sound and the button glows red again. I assumed it was something minor and that warranty may have expired so I put the set in the shop back in December. After keeping it for three months, the tech there identified the problem as a bad Y-main. He said he was going to give up on it as he was unable to find parts affordable enough to make it practical for me to have it repaired. I have been perplexed as to what to do about it. Now I have had it in the back of my SUV for about a month while I have spent hours on the phone with HP trying to get some sort of resolve. I am getting the same run around as others. Out of warranty, so sad, too bad, pay $629 and HP will try to get it fixed for me. That amounts to the as my technicians assessment.....not very practical and may be throwing good money after bad, especially when the price of similar units has come down to that or less, to replace it for new. I hate to just toss it but then I hate to fill the cargo space in my vehicle with it too. Any suggestion will be appreciated.

  • phimoore Apr 21, 2009

    Guest, if you are in the SoCal area you can have the speakers for my broken pl4260n

  • levive Apr 25, 2009

    There is the sound but no picture. When I called HP customer service, I was told that I have to pay $640 for the service and the parts that has to be replaced which is the ys. which is about $300.00 in addition. It's like I'm buying a new television. As a read over, I think this is a common problem from this TV from all the customers who bought this product three years ago. The same spare part is defective and will not survive more than 3 years. I am very disappointed with HP's customer service. I waited 30 minutes before I got a real person on the line and will not listen to my complain. I will never buy any HP product ever. Worst products and customer service I'd ever experienced.

    Just to update this issue, HP has now agreed to replace my plasma free of charge, they dont know how to fix it and after a couple of tries they gave up and I'll get my new one next Friday. For all of those trying , keep trying and don't give up, don't take no for an answer.

    Just an Update here, My new plasma arrived on Monday free of charge, no shipping, no money at all, works like it did when new. Call HP with the number listed and let them have a piece of your mind, you will get results.

Yes you have to replace the Y scan board... the bad part is that this is a common problem with the HPL4260 model TVs and HP knows it. However they will refuse to fix this issue if your TV does not fall with in their serial range of those they claim have faulty parts. I called HP, and the hardware Tech admitted that HP used some cheap sub standard parts in ALL of the models shipped HPL4260... not just the ones in the serial range they (HP) claim... this was yesterday (03 December 2008). However since HP no longer even carries the parts you have to buy them yourself... you can find the parts here: http://www.ued.net/website/index.html

you will need to buy: TNPA3243AB-PA and TNPA3242-PA the Upper and Lower data output scan boards.... aka Y scan... that is according the the HP Tech I spoke to...

    jscruggs420 is right!! After a 7 month long battle with HP arguing back and forth about their product... I found a website that suggested writing their CEO. I wrote a constructive letter in reference to my issue, and how it appears to have been a big scam... WHALA! HP sends me an email 3 days later with a Senior case rep number: 877-917-4380 ext. 79 I explained the issue, and they took care of it promptly!! HP mailed out my YSUS, and scheduled the repair person...however, HP did swear to it that my problem was not the same as the "Free Fix" offer and I was on my own if the YSUS didn't fix it.... The random repair guy showed up some 4 days later.... took 10 minutes to put the new board in and the issue was fixed!!!.

    Call the number, sate your case, be firm that its their issue and not your responsibility to fix... hell even throw in the fact there are countless numbers of people with the same issue that have been getting theirs fixed for free..... YOU WIN!!!

I got mine for free from my neighbor and he was so disgusted with HP that he gave it to me. Since I'm an EE in my day job this was wasn't that hard to repair. The most difficult part is removing the YPPD-J018C Hybrid Module that is under the heat-sink on the YSUS Board. If you are good with a soldering iron, then you might give it a try?

1 or 2 fuses (4A) will be blown so you will need to replace those along with the YPPD-J018C Hybrid IC Module that is under the large heat-sink. Removing the IC can be intimidating unless you have very good soldering skills and a good solder station such as a MetCal. You will need a lot of heat to free the pins before prying this IC up. Failure to do it correctly may lift some of the delicate traces and the new part will not work! When removing the IC I always add leaded solder on these lead-free boards because it flows better. Also adding extra flux and using a Soldapullit Solder Tool works well. You keep adding the solder and sucking it back up...until the pins are relatively clean.

Removing the IC still took me about 1/2 hr. to get enough solder sucked up until I finally was able to stick a screwdriver under it and pry it up. Do this gently, on several places on the IC to break it loose. On my YPPD-J018C IC Module Q1 was blown but since there 4 of these same little semi-conductors, your problem might be Q2, Q3, or Q4? They are easy to spot because they blow apart catastrophically, there was black soot around mine. Anyway, you have to repalce the whole IC anyway but you could actually replace these little transistors if you could find out what value they were. The main reason this part failed is because the white heat sink grease was dry. This means that the heat-sink was not able to adsorb the heat from the board as well anymore and then it just got too hot and failed. So use a good high end thermal grease when you put the new YPPD-J018C part back on the heat-sink. Arctic Silver costs about $10.00 a tube from Radio Shack. This will make the TV last much longer. The YPPD-J018C part should run you anywhere from $39.95-$49.95 plus shipping. Both Suburban Electronics in MD. and Rich-Tech have the part. The whole fix should be under $70.00 when your done and your Plasma TV will be revived!

Good luck!

Hi there, i have the same tv, same problem. I noticed the Y sus board is on the left and has 2 extra, or one long extr aboard. are these to which your are referring to? i took some photosi can post em...

Possible problem: Those large, orange caps (the 5 group and 2 group) are probably bad and buldgeing.. I might pull off some of the orange to verify, if so replkacing these are a good first styart, after fuses....

i see fuse 2 and 3 on the right side, but where is fuse 1? is there another fuse location?

any schematics or help, would be appreciated.

(using a voltmeter, one can see if current is running though since they have that cloth on the outside..)

but that's the extent of using it.

im workign my way though the issue today.

The problem here is you cannot even find that---I suggest you either buy the y sustain board as only circuit boards are sold and NO parts themselves or take it to a shop for an estimate.

I replaced the module on YSUS board and replaced the FS2 fuse on hp cptoh-0602 plazma tv. TV worked great for about 2 hrs of usage time. however, while i was changing the channal few days later since...


Usually, when you replace Y-sustain board, for older plasma, they suggest to replace both Ydrive board (up and low). And sometimes, Z-sustaint.

Im not sure your are an expertise in this matter so be very careful when you open a TV because hasardous voltages can kill you in the worst escenario.

If you are not, don't work on your TV. It will be your sole responsibility.

Check ships on Y drive board (both board are installed on the right side of Y-sustain. They have square black ships that used to get bad. If they don't have aluminum cooler on them, you can see if they are burned or have holes on them. Old plasmas use to have issues with those boards. Before you installed the Y Sustain you should check Ydrive boards. Maybe you damage the Y Sustain because the Y drives weren't good.

Try to replace the fuse, disconnect the Ydrive from Y Sustain, turn on TV and check for voltages on Y sustain (panel has a sticker with each voltage). Hope you didn't damage Y sustain and can find Ydrive board to fix your TV.

And REMEMBER, you can kill yourself when you work on TVs.

Picture went black but you could still hear the movie


Hi- My PL4260N stopped working after about three years, the audio worked but no video at all. The TV worked fine until one day...no more picture.
I found out that the YSUS and ZSUS boards in the TC fail alot...BUT you can get new or repaired ones off of EBAY...
First check for failed components (burned, loose, bulging, etc.) if nothing obvious is failed then check the fuses on the YSUS, ZSUS, and power supply boards...usually if a board has a blown fuse the board needs to be replaced...get the part number and search it in Google and eBay and you will find options for replace/repair.
Mine had a blown fuse on the YSUS board...I got it fixed for $75 through coppell TV (they are on Ebay)....
Now my TV works fine again!
Good luck.

HP 42" Plasma


I do not have a manual, but HP just replaced my Y Sustain board on my PL4260N (Model (ED429AA).
HP replaced it free because of a known problem with something they call "Plasma Mal-Discharge'.
The part number on the work order is 1032298-HS.

This did not fix my pixilation lines across the top.
I have been told that my Y-DRV is probably bad, but I need to pay for that replacement.
But, they did not verify that it is bad and did not guarantee this is what is wrong.
