I HAVE A HP DV2000 LAPTOP WITH VIDEO ISSUES , I REPLACED THE MOTHERBOARD BUT STILL NO PICTURE ALL LIGHTS ARE ON AND THE FAN IS WORKING BUT NO VIDEO..


Hook a spare monitor to the video output, usually on the back. If you get a picture it means the inverter board is bad, or the backlight behind the LCD display, check to make sure the round video cable is plugged into the motherboard. But, if the symptom is the same for both screens, the problem is the Video Graphics Card normally built into the motherboard. If the connector to the LCD is damaged that would explain the issue of no video.

I have a hp compaq laoptop with C Series motherboard. It was not booting up few days back. And i took it to a service center where they told that the motherboard is gone and the motherboard is not...


You cannot replace the motherboard with a different one because laptop motherboards are not inter-changeable between models.
You need to purchase a new laptop, but you can remove the hard drive from the laptop and insert it into an USB hard drive case then use it as an external USB hard drive for backups and file transfers.

The tv has sound but no picture when turned on, but after a couple of hours, the picture shows, and everything is fine. We were told it was the motherboard and it would cost 400$ to fix it. What is wrong?


It is either the motherboard or DM/convergance board that has bad capacitors. It is very common for the motherboard's capacitors to burn out in the newer televisions

HP DV9000 Pavilion Motherboard died again


  1. boss every electronic product comes with warrenty and customers buy them after agrement with the conditions. so lawsuit is available in case the company doesnt solve your problem even if your product is in warrenty period. so surely you can approach consumers court thats available in every nation.
  2. secondly why dont you go for extension of the warrenty period. eg in case of HP its hardly $120 for another 2 years in India for details check out for details in the near by outlets in your area of location. cheers!!

My screen went black


If your Notebook's screen went blank you can do the following:--

1) Try booting with an external monitor. Connect the external monitor to the VGA port given to the Notebook.
Result:1 --- If the external monitor is working fine, then the problem is with LCD. If your Notebook is under warranty you can get it repaired free of cost.
If your Notebook is out of warranty you can go to HP.com and purchase the LCD screen (If you are in USA please go to this link :--- http://h20141.www2.hp.com/hpparts/)

Result 2:--- After connecting the external monitor even the display is not there, then it is the problem with the motherboard. If your Notebook is under warranty then you can avail free repair.
If your Notebook is out of warranty you can go to HP.com and purchase the Motherboard (If you are in USA please go to this link :--- http://h20141.www2.hp.com/hpparts/)

Upgrade graphics processor hp pavilion zv5034us


Honestly speaking, I recommend you to go for a New Notebook rather than changing the Motherboard since it is not possible to purchase another Motherboard for this Notebook with a better graphic card.

The actul Motherboard of your Notebook will cost you pretty more and I personally recommend you to go for a New Notebook with which you can get latest Graphic Card and hardware components.

You can find the list of parts available for this Notebook from HP Part Store from the link below :

http://h20141.www2.hp.com/hpparts/Search_Results.asp?mscssid=EJVUXR20AGCT8PMRJKPJXR6FSGX6C2W2

However, if you donot have any issues with the Notebook currently, go ahead working with it.

Hope this helps...

Notebook is not powering up


You have a fairly common failure of teh power plug on the motherboard. You can get a replacement for less than $100and have it installed locally for about the same price if you are not comfortable doing it yourself.

Motherboards are available here:
