No picture, audio OK, HP PL4260N, outside HP's repair for common Problem. According to HP and your site the Y sustain board needs replacing, problem supposedly is plasma mal discharge. My two-year-old HP PL4260N went blank, too. I called and e-mailed and pestered and HP offered no help. The best they will do is offer to TRY to fix it for $630. Even if they can't fix it, they keep $300! What a way to run a company, huh?

As its necessary to replace the y board if its faulty. try  www.partstore.com for cheaper price boards.

Just constantly call and email HP everyday until you get a deal where you can send it in and only get charged if it gets fixed, otherwise go to a local repair service. Big companies like that are hard to persuade. Talk to managers, ask to be directed to whoever is up there in the company. Write reviews about HP, write to the BBB about them. Something may eventually work, but if it is outside of warranty, they don't need to do anything for free.

There is no way to persuade HP to fix anything I use to work for them. They run a tight ship if you know what I mean. You should ALWAYS buy extended warranty's on expensive electronics they are worth it spite what some people say.
Second, all you need is an anti static wristband you can buy one for a few dollars from any computer repair place that sells products as well, or online. Wear it and you can work on anything without being worried about frying delicate components.
The Y board is what, more than likely needs replacing. So you have two choices buy a new board replace it yourself and hope for the best.. The board when you find one will still be 100-300 dollars.
Or you can just **** it up and buy a new TV WITH extended warranty.

All the best, hope it works out.

I had the same problem and HP has been very helpful, try calling this number 877-917-4380 ext. 79 and be firm tell them this needs to be fixed. They are sending my second replacement part and said they will keep sending parts till it works, this tv is almost 3 years old.

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...

U can buy a new name brand 42" LCD HDTV with all the bells and whistles for about $800 at Costco or Walmart, why not just get a new set, if u fix the old one then what fails next?

If you can do the repair or no someone who can, you can get the part on ebay for around 150. That is far from thr $630 they want. Just do a search PL4260N and you will find your part. Good luck

If you are capable of doing it disassemble it and check the capacitors on the board... especially near the power supply... not just visually but by feel... any that are rounded on the top need to be replaced...

Better check the connections, try to use another cable connecter.

Hi there!

I know how disappointed you are, but that's how business is going, business is going around circles. The HP is offering their best service, because they know how to do it right, its generic if we can say.
Anyhow, I suggest, if you want to try to get it fixed, you need to invest $630, right? and you are not sure if they can fixed it for $300, right? well, if its going to worth saving with your plasma, it is worth trying, but if you can afford to buy a new one. It would better for you, a brand new plasma tv! looks good, sounds good.

good luck man! cheers!
