Blank screen on hp pavilion dv 2000 laptop

Espoo · 07-02-2013 10:56PM #1

Hi All
The missus bought this laptop in 2007. €800. After 13 months the screen started going off. She would turn it off and on again and screen would sometimes come on again too. But finally it packed in. I tried plugging it in to another monitor without success. We left it on the shelves since.
For some reason I took it down today to get another look. I came across a fella on youtube that fixed a similar problem by continuously tapping control alt delete on start up. I tried this and to my amazement the laptop screen worked. However when it came to the screen where you need to enter password, She forgot it! So I tried starting it up again. Screen worked again after a few attempts. I tried getting it in to safe mode but failed. Kept tapping f8 but it went back to the windows xp screen to enter password. So I turned it off and tried it again only this time I cant get the screen to work. I must have turned it off/on more than 10 times tapping ctrl alt delete. no success.
So where do We go from here? Seen a lad on youtube and He had a hairdryer at it? before trying to start it up? Would heating it up improve the chances of some connections reconnecting? Should I go get someone that knows something about taking laptops apart? How much do ya reckon it'd cost to fix?

Any help appreciated

The Graphics chip needs to be reflowed or reballed...these laptops are plagued with graphics problems...reason been they used lead free solder in the assembly process and over time and with heat the solder lifts and cracks from the motherboard and causes the problem you described...In America they issued a recall of the laptops with Nvidia chips but no such luck in Europe!!
Towel, oven tricks only short term solutions and only last a little while )-:

Oh yeah I see where you are coming from. The solder joint needs fixing. This shouldn't be too big a job??

Quite a big job and requires specialist equipment to do a reball. If you want the machine to last do not get a reflow or take a heatgun to the GPU, this will only screw it up even more. With regards to cost for a proper reballing, no idea, but I would say 100+€ easily, someone else may be able to better advise though

It's not just one solder joint.Check youtube for reflow videos. There are DIY solutions involving an oven, at your own risk .....

Cheers, This might be an option if the proper way is so expensive that its not worth fixing.

Reflow is a temporary solution, you'll be back where you are now eventually.

A reballing will be expensive and can be a big job but will offer the best chance for the machine to last.

IF you have windows xp,
Method 3: Bypass Windows xp password on safe mode.

Tip: We cannot bypass windows 7 and vista password on safe mode, because the administrator account of windows 7 and Vista is inactive by default.
When Windows xp was installed, a built-in account named administrator was created at the same time. The Administrator account has a blank password until you create a new password for it. So we can easily bypass the windows password by this leak. Now we try to login Windows with administrator account.
When power on computer, press F8 repeatedly until the Windows Advanced Options Menu screen appears.
Select Safe Mode to boot windows to safe mode.
Click Administrator account to login. OK! You have bypassed Windows xp password.
Tip: We can also use this method to bypass the login password in normal mode – Boot Windows to welcome screen, double press CTRL+ALT+DEL to bring out the classic login screen, and then input: administrator and blank password.
If the administrator account has been set a password, we cannot use the method to bypass the windows xp

Riclad,

You won't get a reball for €50 or even double that I wouldn't think, it's stupid imo to pay for a reflow anyways, as it will only last a few weeks/months if lucky. I don't do reballs and wouldn't reflow machines for people as not only do you cause further damage to the motherboard reflowing it, the problem will happen again-that's a guarantee. A reball with proper lead solder (and all the lead free solder cleaned off) is what is needed, or it's probably cheaper and more economical to buy a new laptop
