I have a 17" HP laptop that my wife dropped and broke the screen; we took it to a local computer repair place here and they said $170 for the screen and it would be a couple days. That was two weeks ago. They called me a couple days after the screen came in saying the screen works now but its now out of focus and that it *could* be the ribbon cable that was damaged and they had to order it to see if it resolved the issue. I told them I'm not paying for parts that *could* fix the issue, turns out it didn't fix the out of focus screen. The tech called me yesterday saying he researched it on the manufacturers website and many others with my same model that had been dropped were found to have a blown fuse on the motherboard. Looked, it was blown, replaced but it still hasn't corrected the problem. He just called me again saying now he *thinks* I need a new motherboard and this *should* resolve the issue.

My question is, does anybody have this laptop, HP Pavilion DV7, and have experienced this problem, know how to fix it, or how I should proceed?

Thanks

Jason

Out of focus LCD? Why is the tech assuming the LCD is good? I would question the LCD.. I do repairs on smartphones and you do run across bad replacement parts. This tech needs to verify that the LCD is indeed good instead of replacing the computer piece by piece. Sounds like he's assuming because it's new its good. I've been burned like that before.

Those were my questions exactly. I asked him to be 150% certain that the LCD was good, to which he told me, they tried the same screen on other models and it worked perfectly and tried 3 other screens in my computer and all of them were fuzzy or out of focus.

So he just called me and informed me that a motherboard is $180. I think these guys are taking me to the cleaner. I'm pissed, but I can't yell at my wife because she's just about ready to go into labor with our first child..

Ugh!

I don't know the specs, but sounds like for just a few bucks more you can have a new laptop.
I replaced the ribbon on my daughters hp, fixed the scrolling lines but the lcd was always in focus.

I have the same laptop. My video went out also. My solution was I bought another laptop.

I've repaired more of these than I care to remember.
An LCD which looks "out of focus" usually means they ordered the incorrect panel, the DV7 uses 2 different LCD panels and it sounds like they don't have the correct screen. FYI the DV6 and several Compaq V series use the same motherboard with a different battery connector.
The DV7 also had a known fault where the nVidia chipset substrate would warp through heating and cooling cycles causing the BGA solder to fracture, there is a fix for it but it's not permanent.

The symptoms of the failure are; no power, distorted pixels on the screen, random locking up/BSOD, no WiFi.
Any idea if the southbridge (controller) chipset is Intel or nVidia?
These DV7s were also released with different CPUs from both AMD and Intel.

Can you take a photo of the panel while it's powered on?
Feel free to shoot me a PM if you need help with this, I may even have some spares for it if you need them.

Don't take their BS, if you were given a set price to repair the HP that's all you should pay, it sounds like this shop doesn't carry out a full diagnostic on their machines.

It was exactly what you said, the board had "hot spots" in it from heating/cooling cycles. It was replaced and it's working perfectly now, as it always did.

$400 later..

I don't think I'll use this shop again.
