Question about HP PL4260N 42 in. Plasma HDTV

9 Answers

I have sound, but No picture (HP PL4260N) plasma 42 inch

My said the TV didn't have a picture...I came home and verified...it didn't have a picture dispite working fine the night before. The TV has very few "run" hours on it, but its about 2 years old. HP wants $629 to repair...I won't pay that for a TV that isn't going to be supported in the near future and they would only give me a 90 warranty on the parts.

    Well, I read this as well. I borrowed my neighbor's OHM meter to verify which fuse was bad (you can't tell because they are white cerramic and can't tell if they are bad visually). I went and bought new fuses after determining that only 1 of the 2 fuses was bad. In any event, I'm unhappy to report that the new fuse(s) didn't fix the problem. In fact, when I plug the oower cord of the TV into a wall socket, the TV powers on by itself and then shuts off by itself within about 5 seconds. No joy. I guess I will have to buy a new LCD or plasma TV and it won't be an HP!!

  • carrod56 Jan 17, 2009

    I was told this my the HP rep who never saw the TV. I now have it at a repair shop and the guy"s telling me that I should replace all 3 boards at the same time (YSUS, Controller/logic and XY board). He can"t seem to find the controller/logic board. My HP is really an LG electronics. Do you have any ideas where to get the controller board or should I jsut taek a chance and only replace the YSUS board??

  • Anonymous Jan 20, 2009

    I have the same problem...it was working great and suddenly lost the picture...

    Called HP case management 877-917-4380 ext.79 they cannot do a thing.

  • bowhnter65 Mar 09, 2009

    I have the exact same TV. Picture worked fine for just over 2 years and then without warning... GONE. I have sound but no picture. Sounds like 2 years is about the life of these. Looks like we won't be buying HP in the future.

  • E_G_L Mar 11, 2009

    I have the same issue, i was watching tv, the screen went off and the sound is still on. HP case management says tough luck, they only cover 12 months, which seems to me would be ok if there was a problem for one person, but if dozens of people are having this issue, they should accept they have manufactatured this wrong and accept responsibility.

  • Anonymous Mar 12, 2009

    No picture, cane hear the sound. Case manager said I have to pay over $600 to get iot fixed. HP made junk TV, spent ~$1500 which is now down the drain.

  • sshillingsbu Mar 15, 2009

    Joy. I have just hit the same problem as the aforementioned users. No pop but sudden loss of picture (black with little white images (about 1 inch) on the outsides. Problem is on all input devices. Absolutely no OSD. Does have sound. Going to attempt the listed number. Will keep everyone updated.

  • kkdtpsully Mar 23, 2009

    Problem : Very DULL pic , but we still have sound. TV bought in Oct. 2006.



    i called the #, they offered me a $629 warranty. If they couldn't fix it we would be refunded $300 of that. I said it was unacceptable and they told me I would have to email the CEO. I am doing this now.

    same problem. have elevated with HP because this was a known default that they were fixing thru the end of the year but now nothing. They are telling me that it was posted on their website but who regularly checks the websites of all their electronics. I registered when I bought the tv and think they should fix it. If anyone is interested in joining me while I fight with HP, I can be reached at kmc2212@yahoo.com

    I was watcing my television and hear a pop and the screen went black. Phone HP and they wanted 659.00 to repair the problem. They referred me to Best Buy who wanted $150.00 to come and look at the problem and if parts are needed, the cost of the parts, plus $35.00 for every 15 minutes that it takes to install the parts, plus $35.00 installation. How much will this cost me? About $600 depending upon the cost of the parts.

First things first:this is a common and actually guaranteed problem in all 42'' TVs that use the same LG display technology.
I'd take it a step further and say it is a common problem of pretty much all plasma TVs made in 2004-2005.
And there's A LOT of them.

So while you can blame HP for failing to support a product released under their brand you also have to understand that the problem is deeper than that.

We have serviced easily hundreds of those boards and we have sold hundreds of DIY repair kits so I know what I am talking about.

Both the Y and the Z sustain boards (6871QYH053B and 6871QZH056B respectively, or some of their equivalents) use the same intelligent power module (IPM) IC and it is unfortunately designed to work on a very high temperature.

It works all right, but it also wears out.

If you have ever wondered how does a semi-conductor wear out just think of it this way: you know how steel is hardened, right? Hot - cool - hot - cool...the process changes its structure.
The very same things happens with semiconductors, except unlike steel rods you have a zone think in nanometers range that expands and shrinks thanks to temperature differences.

It can only take so much and it eventually changes properties enought so that one day there is no semiconductor anymore. It's a conductor.

It busts and you get the problem you describe.

One very simple and essential conclusion is that ALL plasma TVs that operate at high temperatures, in fact ALL appliances that operate at high temperatures, face this problem. Of course it depends on how thick the semiconductor junction is, how was it created, etc. etc. factors that determine how many times it can withstand expanding and shrinking before it loses its qualities.

A second and more practical conclusion is that since the same component is used on both sustain boards you are going to have the same problem on both!
And this is exactly the case!

Don't have enough space here, so if interested, read the rest at our site.

Hope this helps.

    if you have sound but no picture, its the ysus board. I have the same tv and my solution was to email the CEO of HP, I then got back an email that had a phone number, called that number and spoke to a case manager , I told her that I was angry to have spent almost $2000 on this tv to have it last for about 2 1/2 yrs and that was unacceptable. I was offered an out of service repair. On Friday tech came to my house and replaced main board, no help, he said I need a new Ysus board, I called HP back and Ysus board is on its way for repair on this Friday, Hp said they will keep sending parts until it works, free of charge, you might try this.

    Just an update here, HP is now sending a new Plasma out, will have it on Monday. They sent out 2 different parts and techs, still not fixed, then they agreed to sent a replacement plasma free of charge.
    Your best solution is to call them with the number I listed and let them know how you feel, they will help you and in the end if they can't fix it they will send you a new one, good luck.

The problem comes from excessive heat in the plasma. _Most of the TV makers avoid assembly Fans inside the tv to reduce price and noise. I repaired a PL4260N model by changing a IC which was short-circuited, located in the Y-Sus PWB. Its located below a Heat Sink. In the solder side of Y-Sus PWB, it have labels with Vs, Gnd, 15V, etc. If you have a Multimeter, make sure if there is a short-circuit between Vs-gnd. If its so, then you have to replace it (50 dlls). And the fuse also. Good luck!

The problem is with the YSUS board. Only 1 fuse (4A) was blown so you will need to replace that one along with the YPPD-J018C Hybrid IC module that is under the large heat-sink.. I'm an EE in my day job so I have done this sort of repair from time to time but it 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 ****** 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 board 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. Also, one of 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 heatsink. Something with silver in it cost about $6.95 a tube. 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. Good luck!

    Also, please note that one or both of the fuses will be blown on the YSUS Board. You will need to replace those fuses too. I'm not sure if I was being clear enough above in my description of how to replace the YPPD-J018C Hybrid IC Module that is under the heat-sink on the YSUS board. This is what blows 95% of the time. I should have also noted that just replacing the YPPD-J018C and the fuses does repair the Plasma TV for Cheap! Cost me only about $60 bucks total including a tube of Arctic Silver heat-sink grease! HP wants $629.00 for repairing this board, that's robbery! I don't buy anything from HP anymore, not because they make some bad Plasma TV's, all companies make mistakes from time to time. But HP doesn't care, their Customer Service is extremely poor and they are the #1 company that sources jobs to China and in the US! They use a lot of temp and foreign workers (non-citizen) here in the US. That's enough for me to not buy their products! If we all no longer buy their products, maybe then they will notice their sales are dropping and get their act together?

    You can pick up a tube of Arctic Silver at Radio Shack for $9.95 and it has far better heat absorbing abilities that the inferior thermal grease that they used originally.

    You don't need the Wigapry tool, you can wiggle the pins and break them loose using a small needle nose pliers. Just make absolutely sure that you have almost all the solder
    removed around each pin before you start with the pliers.

I tried switching the fuses and that didn't work. I don't think I'm going to mess witht YSUS board, this has taken too much time as it is. Finally, its too bad that there are so many posts with the same problem for the same TV model, and that each post has potentially different solutions. When I came to the site two weeks ago, I only found the solution of switching the fuses. If I had known about the YSUS board, I would have tried to replace that as well.

    Switching fuses is as good of idea and as much as a solutuon as it would be to rotate your tires when one of them is burst and hoping the car would drive well.

I like solution 3 listed above, but if you're not that technical, here's something else to try.

As described above, this problem is caused by something called a YSUS board going out. You can buy the replacement parts for about $300 dollars or there is a company that will fix the YSUS board. I don't have instructions yet for removing the YSUS board, but if you've got the skills or know someone who's good with electronics, you can fix the board for about $120. I've got the same problem with my 42 inch plasma TV. I called PTS Electronics today at 812-824-9331 (their website suggests you call 800-844-7871). I spoke to Kelly. She was very helpful, but said anybody at their number can help.
Kelly said that you do not need to call first to get a return authorization. To get the YSUS Board fixed, you need to remove yours and send it to the following address:
PTS Electronics
2000 S. Liberty Dr
Bloomington, IN 47403

When you ship in, you should include a letter with the following information:
Your Name
Your Mailing Address
Your Phone Number
Payment info for the $122.60 to repair the board. If you want to pay with a credit card, note that in your letter and that you want them to call you. They'll call you to get your credit card info when they receive your board.

She suggested shipping via UPS and insuring the part when you ship it.

I learned some new things when I spoke to her. If you'd prefer to replace the board in your printer, you can use one of the following alternate parts to replace the YSUS board:
Part made by LG - part #6871QYH053A
Part made by LG - part #6871QYH053B
Part made by Toshiba - part #75003031 http://www.moduslinkptstvboards.com/75003031-P6096.aspx

Out of the three alternate replacement parts, the only one they currently have available is the Toshiba part. They have it listed at $254 (I thought Kelly said $268 - maybe with shipping?) with a core value of $65 that you'll get back if you ship them your broken part. That leaves you paying roughly $200. Having them fix my part seems like a better option to me. Kelly also said that all these parts for the HP TV are refurbished parts - none of them are new - that's why they want you to send them your broken part.

Link to PTS website with information about ordering 1032298-HS (http://www.moduslinkptstvboards.com/1032298-HS-P1628C13.aspx). They currently have 0 available for sale. The message on this page tells you to contact them to arrange repair using the information provided above.

Toshiba Plasma TV HP 42 Inch pop no picture


Most common issue is power supply board fails--Plasma sets do not sell single parts--only a complete board---may need a tech or shop to look and determine what is wrong.

I can suggest things but need to know your skill levels--this is not for everyone....

We have lost the picture on our 42 inch hp plasma tv model pl4260n, we get sound but no picture?? is this a known issue? probably 3 to 5 years old , just happened in the middle of destination truth. nobody...


If it is not a loose connection (internally), it may be most probably related to your picture tube. Check it out and if found faulty get it replaced. If your are in any warranty period (I don't think so since it is 3-5 years old), don't do anything and just inform them, or else you will loose your warranty security.
