HP Pavillion dv9657em - not quite two and half years since purchase.
I have had an issue with no image on the screen of my notebook, I can't even see the BIOS screen at start-up and all I get is a series of small white, fuzzy lines that gradually merge to black.
This appears to a common problem in the US and seems to be due to a failed VPU (Video Processing Unit), caused by overheating. Some notebooks have been identified as having a faulty chip by NVIDIA. Having spoken to HP, I have been told that my notebook is not one that has a faulty chip, but one where the chip has failed anyway.
In the US there has been a Class Action Lawsuit filed against HP for this but there is nothing of the sort in the UK.
Granted, if my VPU has failed after two years because its one of the odd ones that does, then so be it, but surely HP should do something about it because its down to bad design of the laptop that it overheated and then failed.
Has anyone in the UK had this problem and found a solution or had any success talking to HP? ...because I haven't.

My DV9000 is now not showing any video on startup and only after it gets a bit warmer does it begin to show some output. Mine is an AMD model. My son had the Intel version and the same happened to his jsut a month ago.

Just to let you know what I ended up doing - because it did get a result.
I found out that my particular problem was probably associated with something called the nvidia defect and theres a forum I found (www.thenvidiadefect.com). Following what it suggested I got a local guy (who was a qualified HP/Compaq person) to diagnose the problem, he came out to see me and wrote my out a letter explaining what he thought the problem was having done a series of tests for£30. His opinion was that it was 'beyond economical repair' - with that in mind I sent a copy of the letter he had written to PC World where I bought the laptop and was allowed to gain compensation from them which equated to half the cost of the laptop as I had used it for half of its expected lifespan (2 and a half years). They also let me keep the laptop which I then sold for a little extra on top.
The bottom of this matter is - if this is the problem your laptop has, then it can't be fixed in a way to make the problem go away is what I have gathered from hours of online research.
So there you go - hope it can point you in the right direction!

Hi, My 3 year old DV9657em has the same problem, hence the reason I've come on here looking for a solution. When I turn on the laptop the screen stays black for up to 45mins, then it beeps & the wireless led turns from orange to blue. If I then re-boot I can start it in safe mode (if I let it start normally I get the black & white or coloured vertical lines). I have tried loading updated graphics drivers, rolling back to original drivers, full system recovery to factory condition, but all to no avail. HP want £15 before I can talk to a technician, I am reluctant to do this if he is then going to tell me that the motherboard is kaput, which seems to be the theme from this thread & the US version. Did you make any progress in fixing your laptop?
