dv2000 Display Problem

Last week out of nowhere i noticed some banding on my display. It would be really bad all of a sudden for a few seconds and then disappear for a few mins. It had not been dropped or mishandled at all. 2 days later the display completely went black (but the backlight was still on). I have been doing research about what the problem is and have read alot about how HP had a bunch of notebooks with bad motherboards and GPU's that had to be replaced. My computer still works fine - just with no display. When hooked up to an external display it work no problem. And the original display will flash on occasionally as well.

My question is: Do I have the same problem as mentioned above with the bad motherboard?
Or is it just a display problem (that can hopefully be fixed with a quick display replacement?

 

It could still be the infamous defective NVIDIA chipset problem, but it's more likely to be either a bad internal LCD cable or bad LCD panel. Regardless, since it sounds like a defective NVIDIA chip if you ignore that external monitors work, see if HP will fix it under their enhanced warranty program:

I vote bad LCD cable. In fact, the cable wasn't bad to begin with, rather the way it was handled at the factory wasn't too forgiving.

I had to take apart my DV5 after just a few days of owning it because the touchpad ribbon cable broke. Reason: They bent the hell out of it. It was long so i cut a bit of it then plugged it back in and it worked. 2 weeks later it broke again. At that point i took the whole thing apart to gain access to both ends of the cable, removed it altogether and replaced it with one rescued from my stack of broken DVD drives. Guess what, 2 months and no problem.

I'd trust a 12-year old kid more than HP's service people, but being a LCD cable, which they like to make different on every model, i don't think that DIY replacement is an option... So you'll have to send it in.

HP = Good designs, poor builds.

 

im out of warranty, so im definitly going to take it apart and check to make sure the cables are plugged in. is there anyway to tell specifically that its a bad cable or panel? considering the [horror] stories ive heard about sending into hp service center, im definitly keeping that as a last resort.

 

Since you'll only have to remove the top panel (the one with the touch buttons) to gain access to the LCD cable, you will still be able to turn the laptop on and have it fully functional. So you can try turning on the laptop then wiggling the cable and see if the picture comes back.

 

mm, thought id have to remove the whole screen panel..but this makes sense. good call, ill have to give it a try, thanks!

 

Nah you won't have to remove the screen panel, the signal cable is going to be to the left of the power button.

Also, to remove the LCD screen itself you will only need to remove the bezel around the screen and the screws hidden underneath. You won't need to remove the screen casing from the main body.

 

Ok, how do i remove the top panel?

I have info on how to remove the screen (if necessary) and i see how to disassemble the entire notebook in the faq sticky in the forums. Is that what i have to do just to remove the top panel?

Scroll down and you will see "dv2000: Maintenance and service manual". Download that and see for yourself. If it's anything like my two notebooks (and i think it is), you will have to remove five screws on the back. Two on the corners, three under the battery. Then just lift the quicklaunch button board from one of the corners.

Sorry for the way i said it in my earlier post, the top panel is something else.
