Here’s how I fixed a Compaq Presario V6000 laptop motherboard with “no video” issue.
Also, this fix might work for the following HP/Compaq motherboards: HP Pavilion dv2000/dv6000/dv9000, Compaq Presario V3000 and probably some other models.
This repair might be harmful for your health and baking motherboard in an oven probably is a bad idea. It could be toxic. I did this repair for myself, at my own risk. If you decide to use these instructions, please do it at your own risk.
FIXING “NO VIDEO” ISSUE BY BAKING THE MOTHERBOARD.
Problem description: I had an abandoned Compaq Presario V6000 computer. It was turning on when but after a few seconds turning off by itself. There was no video on internal screen or external monitor. I tried another AC adapter, new memory modules but it didn’t help. I was pretty sure the motherboard failed.
Research: After I did some research on the Internet, I found that this is a known problem with Pavilion dv2000/dv6000/dv9000 and Presario V3000/V6000 motherboards and most likely related to the graphics chip failure. The graphics chip is soldered to the motherboard. Apparently, there are bad solder joints between the chip and motherboard. Overtime the chip separates from the motherboard causing all kind of video problems.
Possible solution: One guy suggested baking the failed motherboard in a conventional oven preheated to 385 degrees Fahrenheit for exactly 8 minutes. This process should reflow the chip solder joints and give the motherboard a second life.
I had nothing to lose and decided to give it a try. Here’s how I did it step by step.
First of all, you’ll have to disassemble the laptop and remove the motherboard.
Remove all peripheral components installed on the motherboard (memory, cooling module, CPU, etc…). Remove all protective mylar tape. The motherboard will be baking at a very high temperature and all that can burn has to be removed.
Take pictures while stripping down the motherboard. They will help you to put all removed protective films back in proper locations.
This side of the board has been stripped down.
You can see the graphics chip on the right side from the CPU socket.
Remove all mylar from the other side of the motherboard. Disconnect the audio cable.
The motherboard will be seating in the oven on the baking pan. In order to elevate the motherboard above the baking pan I’ll use a few screws.
I installed screws in four corners of the motherboard. There are plenty holes for screws.
You can see there is a 3/4 inch gap between the board and desk surface. The graphics chip is facing up.
Place the motherboard on the baking pan. Make sure it’s not touching anything.
Preheat the conventional gas oven to 385 degrees Fahrenheit and place the board in the middle of the oven for 8 minutes. You’ll smell some burning plastic in about 6 minutes.
After that remove the baking pan with motherboard and let it cool down for about 30-40 minutes.
Assemble the laptop back together and see if it works.
This fix worked for me! After I assembled everything back together, it started properly right away. The video had no glitches.
The next time I explain how to repair the same issue using bubble wrap. This method requires no disassembly.
