My set will be two years old in May, so it is out of the one year warranty. I have no extended warranty. You can see my posts above.
I began having pixel flare (red static like pixels that flare up in mass and randomly all about the screen, more on the left side than the right.) I alerted HP to this problem right before my warranty ran out, and again via email about two months ago. On the email I attached many of the posts here, saying this must be a defect in the product.
Last Sunday night I spent about 45 minutes on the 800 number with Chuck. We went thru the usual steps of resetting TV via the wizzard, the cold shut down, etc, but the pixel problem of course persisted. I informed him many others have had the same problem as posted on the AVS Forum.
He took lots of notes and knew I was past warranty. He was a very nice guy, polite, very knowledgable, and very professional. After going thru the exercises he indicated to me this issue was a problem in a number of sets and that he was authorizing a repair at HP's cost, as if still under warranty, essentially due to a production problem. Two days later via FedX parts arrived at my house and today, Greg, a local HP contracter, came to my house.
We pulled the TV down from the wall mount, laid it face down on blankets on a table, and he pulled off the back housing. He put in a new controller board, which is located under some other boards mounted above it on another frame. I was glad I watched 1st hand and close up as I also noticed that a multi-wire (8 or more wires) plastic connector on one of the other circuit boards was unevenly in place -- essentially not locked down. he said "good catch" and properly reset the connector.
He put the back housing back on the TV and we hung it back on the wall and hooked her up. Immediately upon firing up with the "HP Intializing" screen coming up I could see that the nasty red (and sometimes green and blueish) flares were 100% gone. I have been running the set for about 6 hours straight today and it is still pixel flare/static-like burst, what ever you want to call them, free. Those nasty little bas*rds are gone.
The tech took the old control panel with him and sends that back to HP.
I am a very happy camper and the TV is performing flawlessly, with a picture that is better than ever. Cost to me was zero.
So, I have gone from a person who would have never purchased another HP product if they had not fixed this TV, to one who was rather impressed with my dealing with HP this week.
The control panel is not very large -- maybe 5 inches by 7 inches -- and has an LG micro-chip of some sort in the middle.
I am sure that the control panel must have been defective, but I also wonder if the loose/improperly seated connector may have also been causing me problems. At any rate, my TV is again cranking out at fine HD picture.
I will update this message if I experience any problems.
Good luck to others.
