    Hi, can anyone help?
    I had a problem with my DV1000 laptop. The screen disply went black but if i shone a light on it i could see it was still working ok.
    After reading through the forum i decided to replace the screen inverter as this seems to be the usual cause of this kind of problem.

    Unfortunatly this didnt fix the problem. I noticed that when i connected the new inverter the screen would light up for about 2-3 seconds then go dark again.

    Someone suggested a hard reset which involved removing battery and power lead, then hold down power on button for about 15 seconds.
    I did this and now laptop is completly dead, no signs of life anywhere.

    I have checked the usual, battery and power lead, both are fine. Luckily a freind has the same model so it was possible for me to test those.

    Has anyone got any ideas what the problem could be. :confused:

    Did you try removing the RAM? Try that, pull the Dimms or Dimm of yor Memory Ram. Before doing so remember to make sure that the battery and AC is not connected. And repeat the hard reset after removing the RAM, it woth trying as it once worked for a friend of mine.

    I've just tried that. Still won't work. I dont understand what the reset could have done. Apart from the screen problem it was running ok before.

    Taking out the Real Time Clock battery cuts off all the electricity from the motherboard thus causing it to reset the bios to default settings. Give that a try and let us know.

    I dont believe it!, I stripped it down again for one last time just to check for any loose connections. Put it all back together and then i picked up the remote and it turned it on, everything seems to be working as before, apart from the power switch which does nothing. There is still the problem of the dark screen, i know its not the inverter because i tried a good working one from my friends laptop (same model). Do you think it could be the backlight?

    Well to be honest it's really amazing you got it back. You definitely must have some problem with the display, so if it would be possible somehow to try changing it and see how it behaves, I guess that's the only way you could discard any other hardware related issue. Something I don't undestand is if the screen is all black (nothing is display) or it comes up and then it gets black? Another thing is When did the power button stopped working?

    The problem with laptop's hardware is that every part is tightly unified and any failure in one place could affect others hardware that may not be directly related to the original failing hardware. So if it's the backlight the only solution you may have is changing your display, but Why you're having problems with the power button?

    When i say the screen is black, i mean it is dark. If i shine a light on to it i can see the image on screen. The power button stopped working after i did the hard reset. i could swap the monitors over with my friends model but i really dont think that is an option. I don't want to mess his up as well.

    Hi. I'm having almost exactly the same problem here with my DV1000. After replacing the inverter because there was no backlight in the screen, the screen briefly flashed, went off, and from then on, I've been unable to power the computer on using the power button or the remote.

    I'm clueless about what went wrong with my laptop.

    I seem to have a similar problem. Yesterday afternoon it worked great and now today Its not working. The buttons directly under screen are lit up however the display is blank (no color, black) and it seems as if the mobo fan turns on and than off pretty quickly. The laptop is about 3 years old, and from what Ive read online, the mobo is a fairly common problem with this model. Any suggestions?

    Yes, the motherboard is a common problem for the dv1000. Luckily I had an extended warranty that paid the cost of 700 dollars to replace it. Try grasping the laptop with your hands from the front....raising it off the table and try booting. Mine would boot after stressing the motherboard like that. Once it booted you could lower the laptop. I would look closely for a crack in the mb or cold solder joint.

    I'm having the same problem, the screen is dark and I can turn on the backlight by pressing the display switch (the little button near F1 that gets pressed when you close the display), but the light turns off inmediatly. I have replaced the inverter, but I still have the same problem, I'm thinking about replacing the backlight, but I think its a very risky operation. I did this on a useless IBM and I broke the lamp without any effort, it is a very thin lamp!!! Does anyone have tried replacing this backlight tube?. I think this is the only option left, otherwise I would have to replace the full display.

    ok for the record this is because the actual backlight is bad i had a toshiba laptop a p15 uses the same screen as a dv5000 the light would come on all redish for a couple seconds then turn off i asumed inverter replaced it worked for 2 hours then burned replacement inverter out at that time i was pissed and continued to look into other things that could be the problem i found a guy on ebay who sold backlights completly accidental. so i gave it a shot the backlight was $25 i took the screen apart and resolderd in a new backlight put it back together and it worked great still does its been working for at least a month or 2 only thing is when you dimm the light it makes a buzzing noise but that might be because i removed the little rubber grips on the end of the backlight its definetly a replaceable item but kind of hard at the same time
