    HP dv2000 posts, but nothing afterwards

    Hi Guys,

    Wow, been a long time since I've been on here. Hope all are well.

    I have a friend's HP dv2000 notebook, which will turn on and post with the HP logo screen, but after that the screen goes black and that's all I get.

    I noticed the hard drive is reading after the screen has gone black, as if it is actually loading windows, but I don't hear any login sounds. If I try pressing any keys on the keyboard, it will eventually just start beeping every time I press a key.

    Motherboard? Video? What do you guys think?

    Thanks,

    Jay

    Did you try booting from a CD? I always start with a hard drive diag and memory test.

    What happens if you try to boot into Safe Mode? Same thing?

    Hi Guys,

    Thank you very much for the feedback. UPDATE: It turns out the screen isn't actually going completely blank....when I was at my other shop, the lighting is different there and it actually does boot to the Vista login screen, but the display is extremely faint.

    So, to recap - When you turn it on, it posts with the HP logo, then the screen actually drops down in brightness, so that you can just barely see what is loading. I've tried the function key + brightness levels, but it doesn't make a difference. Upon further inspection of the screen, the one hinge is loose...it looks as though it was dropped on the hinge of the screen.

    Do you guys think it's a bad LCD?

    Thanks for the help, much appreciated.

    Jay

    Could be a bad FL inverter. I don't know whether that laptop has it built into the display or not.

    The hinge problem is a known issue. You might get more help at this site:

    Thanks for the reply.

    What is an FL inverter? How is it installed in the notebook, something soldered or is it fairly easy (and economic?) to replace?

    Thanks again!

    For many HP models, the LCD assembly part number is for the entire top half. That includes the LCD and Inverter board. The Inverter is usually a 2-3" circuit board with a couple of plugs.

    At least check out the link I posted. You may be able to get it repaired by HP.

    Just thought you should know about the problem with the Nvidia GPU on these laptops (I've got one in my cupboard working as an expensive door stop!).
    Google for the problem. They break all the time these laptops and should have been recalled long ago!
    Sometimes the POST just beeps three times, sometimes you get distorted stuff on the screen.
    If the above posts dont help you, try turning the laptop on, close the screen, wrap it in a towel then leave it to overheat for 20 minutes. Power off then power on the laptop and it should work OK for about an hour ;^)
    crazy i know!

    Okay guys,

    I tried going through the HP Limited Enhanced Warranty program, and even though the dv2000 series is recognized by HP as having this type of issue, this particular dv2000 model is not covered. Other models though, are being repaired by HP for free, even out of warranty period. I tried sending in proof of purchase, but no luck.

    So, back to this FL inverter stuff. What is the best approach to get a P/N for this, and to get a price?

    Upon further inspection of this notebook, I'm noticing that the display is actually there, it's just very dim. You can barley see it, but if you look closely enough, it's actually booting to the Vista login screen. It reminds me of being outside on a sunny day and trying to use your laptop...it's almost impossible to see anything on the screen, but it's there.

    Any ideas? Thanks for all the help to date. Not to sure about that towel thing....why would overheating it help?

    Jay

    When I google FL inverter HP dv2000, I get a number of hits-but it looks like the part number varies according to specific model number. But there are pictures of what it looks like, etc. What you are describing would seem to fit. The part is not outrageously expensive.

    DV2000 is not the actual model number. You need to get that first.

    Majority of the time, the backlight on the LCD goes bad, not the inverter. LCD panels are expensive. Once you get the part numbers off of part surfer

    I've never heard of the overheating trick, but I don't see how it would help.

    Thanks for the great replies.

    I see the FL inverter is fairly cheap on eBay. I've also come across a website that describes how to test the existing one, although this may be a little above my skill level.

    What you say "backlight" do you mean the actual LCD panel? Or is the backlight a seperate part?

    Again, Thanks!

    The backlight lamp is part of the LCD. You would need to replace the entire LCD.
