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.

WARNING!
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.

STEP 1.

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.

STEP 2.

This side of the board has been stripped down.

You can see the graphics chip on the right side from the CPU socket.

STEP 3.

Remove all mylar from the other side of the motherboard. Disconnect the audio cable.

STEP 4.

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.

STEP 5.

I installed screws in four corners of the motherboard. There are plenty holes for screws.

STEP 6.

You can see there is a 3/4 inch gap between the board and desk surface. The graphics chip is facing up.

STEP 7.

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.

    I’ve heard you can use a blow dryer. Would that work without having to disassemble the laptop?

    I bought a persario v6000 off Craigslist about a month ago. After two weeks the wifi stopped working, then about a week later I went to turn on my laptop and it would just keep trying to reboot every 20sec or so and nothing would come on the screen. I read this posting and thought, what do I have to loose? I’m not a computer guy by any means, never taken one apart. Last night I was up until 3am taking the thing apart and puting it back together. I put the mobo in the oven for 8mins at 385 degrees. I’m now posting this comment with my Persario. I can’t believe this worked. Hopefully it will last, don’t want to go through that process again LOL!! Thanks so much for the info.

    PK,

    would you recomed this way or with a blow touch/heat gun that other people seen to be doing

    I didn’t try fixing motherboard with a heat gun.

    is it ok to use a fan oven, do you still use it a 196 celsius, or do you turn it down to 180 ish celsius

    Hello Thank you very much for your advice did this today to a laptop i aquired from a friend and works great now no problems at all thank you for your advice A++

    HA. Why not just use a heat gun. It would be faster and more efficient while not burning up all of the other components.
    Also you can purchase a rework gun for not that much.

    sorry for my english, but im italian, but im here up to all because I’ve got to death with HP!
    please first to starting the mod, read all here, because after there is 3 problem by that mod
    1-by noise from cpu fan, and if for you is frustrating…
    2-the life of cpu fan heatsink can is short, depending if go faulty by poor building materials
    3-when is not connected with ac power, the battery half hour and is out

    some considerations…
    their is not one good house for build the pcs, i know something on it, i have a lot of skill for repair, and in the major, the brands who go broken, is hp, hewlett packard, acer, for dont talk of minor brands…all shit…

    DELL? PERHAPS is a little more good, but how all pcs, have 2 problems: the hot and the dust.

    i all the days dismantle, test, reassemble pc and so on (when you think to buy one laptop on ebay, half dismounted, considering the expensive exit of money from your tasks for take the spares which them dont have; monitor? 70\100$ hd caddy? 40\50$ who exit from your task, but how much during? yes ok, there is a lot of affairs on ebay, but if you are in USA dont buy in China or Europe\overseas, find to buy near you, ok?

    for a lots of reasons (if the spares\object is broken, wrong etc)for send back the spares, the cost is lower than overseas, undstnd?
    but dont buy that brands and, up to all, buy like new if its possible for you.

    NOW, for all peeps who dont know, when open you laptop for do that reflowing (i talk of dvxxxx series), cut the white wire of the cpu fan.
    This causes the CPU fan does not stop, NEVER.
    YES I KNOW WHO THIS IS FRUSTRATING BECAUSE OF NOISE, BUT YOU WANT SEE YOUR LAPPY MITIGATING IN THE CENTURYS? THEN DO THAT.
    but dont leave the cutting wire as is, put insulating tape on the cutin wire (if the wire go to touching the internal circuit, your laptop can go burnin, then attention on it or..puff!
    on the cutting wire, im not sure however, its is at your own risk if u want do a try for put on circuit…mah…are you stupid?)
    this can help your motherboard to live but much more long as you can imagine.
    in that manner, the cpu fan never stop, only when reboot your pc\laptop stop for 3\4 sec; follow my advice, then after 2\3 hrs, put your hand on the left of the keyboard, where is cpu (at the left of keyboard) , how is now? is cooold.
    ok thats all, i have do already 2 times, the reflowing at my dv6000 amd and, chit&chat that fat bstard who now soldering without the lead and, whit that issues have stolen a lot of money around all the world…the HP…yes yes, this make sense, hp pay tax by this stolen money and, a lot of pcs is stopped, the governor is satisfyed and…the earth can breathe, everything fits, this have one sense?
    i called that also markets strategy, them are in their luxurious palace and you cry…buhu…im without pc now…damn hp…buhuhuuu…
    or in that manner or…in what other i can make me satisfied?
    now your beard is long till at your knee, and you all are still thinking that, and after there is also the hp assistance…now comings the very cocks amigo…

    Slaveto,

    This is the funniest way to repair a mainboard :) the plastic conectors for memory, keyboard an other will melt in oven …..:)

    They didn’t melt in my case. The laptop still works after this repair. :)
