We bought this HP PL4260N TV on September, 2006 at a Best Buy in Eugene, Or. Feb, 2009 the screen went black and I could still hear the audio. I immediately searched the internet for any solutions. After doing that for a couple of hours, I called HP Case mgmt from a number I found on a forum, 877-917-4380 Ext 79 and talked to and said that this was the last step, there was nothing he could do and when I asked to talk to his supervisor, he said that his supervisor doesn't take any calls from the public. He then told me to call the HP Tech Support, since I should have done that first to get a ticket number. During the course of the conversation, this HP tech support person told me that "It sounds like the "Y sustained board has gone out." I said I understand that this is a known problem and he said, "Every 50 or so TV's manufactured missed a solder." He asked me if my model's product number was EK430AA and I told him no it was EK429AA. He said that number wasn't in the known range. He told me that up until Jan 2009, HP was extending the warranty, but not longer. He told me that sometimes TV's just get overused or overheated and that can cause the Y Sustained Board to go out. I asked him that HP extended the initial warranty because of this problem, so why wasn't I contacted because my son and I filled out the warranty card? He didn't know. He told me that I could buy the $629 extended warranty and then a HP service person would have 3 tries to get it working, but this was not a guarantee that he could get it working. If the TV couldn't be repaired after three visits, then I would only owe $369.00 and I guess I would have to wait for a refund of my $260, plus I would have a HP TV that didn't work! I repeated this procedure three times back to him to make sure I understood that my $629 wouldn't guarantee a working television. He assigned a ticket number. I thanked him and hung up. I then sent a E-Mail to the HP CEO, Mr. Hurd and was told another case maneger would contact me.When I was contacted itwas same song and dance that was told to me previously> Hewlett Packard should be ashamed! If you know of anyone else with this HP tv problem, please direct them to this web site. http://www.HPplasmaLAWSUIT.info Hopefully, we can have some recourse for this defective product.
