HP DV1000 - Dim LCD

Error in image Pin Number





This was a challenging dog of a repair, but after too many hours I had to give it up. Items checked, replaced or repaired. LCD cable - replaced LCD connector - replace and repaired Invertor - checked backlight - checked LCD - checked Lid Switch - checked The LCD was first checked with a known complete lid from another DV1000, the unit still showed same result. So backing up
  • checked the LCD connector first.
  • noticed connector had internal damage -replaced (same problem)
  • noticed motherboard pin 29 was also blown off motherboard - repaired (same problem)
  • lid switch check for open/close continuity - passed
  • backlight - passed
The conclusion is that that motherboard damage was greater than initially reported or known. Previous tech had made some minor mistakes, but nothing serious.

    Remove the battery and try to power the laptop on with adapter only and see what the result is.

    SAM: This was not a basic clear CMOS or BIOS issue. It was a MAJOR electrical defect -see pictures. Contact pads were shorted and blown away, most likely by a spill. I try not to post the basic stuff that 11hundred other sites list. But more of, How I fixed this problem or that problem.

    Also: Correction in image of LCD connector. It should read Pins 39-40 not 1 and 2.

I cannot repair laptops for you via the internet, I can only answer questions related to posts. This is because I have not had experience on every motherboard that is out there. Bear with me.

If you do need it repaired. Contact me for quote (US/CDN Only)

Important parts on DV6000 and DV9000 series

Image
These are important parts if you are looking for shorts or opens on the DV series. This image shows the location of the FDS6679. A common cause of shorts in the DV series. When the power supply is plugged into the laptop and it shorts out/turns off it's usually caused by this MOSFET being shorted.  Plainly stated. You plug the adapter into the DC Jack and the Blue Ring fails to light up, and the Power Supply shuts off. Giving no power to the tip. To reset adapter, unplug from AC (mains) and wait 15-30 sec. Then plug in again. The adapter is not damaged, since this is how it is protected. These parts do not determine charge time or per centage. The FDS6679 only closes to complete Positive circuit.  The AO4407 only closes when the battery is plugged in. As a test- Check the voltage of the Drain side (pins 5-8) with AC adapter and no battery - you should see 0 volts.  When you contect the battery you should have 10-14v depending on DV6000 or DV9000 series. IF the AO44...

What Kills HP DV series laptops?

Image
The number one issue with DV Series is: Blank or No Video displayed. The number two issue is : (tied) No Wi-fi or Continuous rebooting After repairing a number of HP DV Series laptops. I wanted to isolate the problem and make it easier for me to fix, and have them stay fixed! So digging deep into them I can only come to a couple of conclusions of why they fail. 1: Manufacturing - Hann-Starr Either the oxidation on motherboard or the Graphics Chips. Since the failure comes in both versions AMD and Intel lines. And in Intel and nVidia GPU's it seems it could be at the factory. 2: Distribution - nVidia Could the transit time and shipping packaging be contributing to the oxidation on the GPU? On one unit after a number of reflow failures, I decided to remove the GPU and prepare to 'reball' the chip. Then and only then did I notice there was no solder on some pads. So that points the finger to nVidia. Oxidation is the culprit since the solder balls are put on a ...

DV9000 Power Issue

Image
This HP DV9000 arrived with power problems. Difficult to diagnose simply by looking at the bottom side of the board (which faces tech when opened). When the power cable was disconnected from the board an obvious scorched connector was noticed. This 4 pin plug supplies power to 2 sections. Not wanting to be too verbose, I will simply say that all 4 connections to the motherboard are needed and when one pin is scorched and oxidized, it cannot provide adequate current or voltage. So the plug end was replaced, and the interior of the jack was cleaned of carbon residue from the scorching. The number of issues with this unit, makes for a days work. Power issues, broken LCD issues, SATA connector, USB port all on one machine. Everytime I fix one issue another pops up. And the customer wants it fast, but at a cheap price. When does it end?
