Here’s how I fixed a Compaq Presario V6000 motherboard with “no video” issue. Not sure if this fix will last forever but it works and the laptop is back to life.
Also, this fix might work for the following HP/Compaq laptop 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 could be a bad idea. It could be toxic. I don’t know if it is or not. I did this repair for myself, at my own risk. I’m just sharing my experience. If you decide to fix your motherboard the same way, please do it at your own risk.
Again, proceed at your own risk. Otherwise, close this page and take your laptop to the professional repair shop.
FIXING “NO VIDEO” ISSUE BY BAKING THE MOTHERBOARD.
Problem description: I had an abandoned Compaq Presario V6000 laptop. The laptop was turning on when I press on the power button but after a few seconds turning off by itself. There was no video on the laptop screen or external monitor. I tried another AC adapter, new memory modules but it didn’t help. I was pretty sure this is motherboard related failure.
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 (aka GPU or video chip) is soldered to the motherboard. Apparently, there are bad solder joints between the graphics chip and motherboard. Overtime the graphics chip separates from the motherboard causing all kind of different 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 graphics 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 films from the motherboard. The motherboard will be baking at a very high temperature and all that can burn has to be removed.
Tip: Make lots of pictures while stripping down the motherboard. They will help you to put all removed protective films back in proper locations.
STEP 2.
Here’s how the same side of the motherboard looks without protective plastic films.
You can see the problematic graphics chip, it’s on the right side from the CPU socket.
STEP 3.
Remove all protective plastic films 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 motherboard and desk surface. By the way, I positioned the motherboard so the graphics chip seats on the top.
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 motherboard 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.
Install the motherboard back into the laptop, assemble the laptop back together and see if it works.
This fix worked for me! After I assembled the laptop, it started properly right away taking me to the BIOS setup menu. I didn’t have the hard drive, so I tested my laptop with a Knoppix live Linux CD. The laptop video works great!

Holy cow! I just did this in the oven, and it worked. It really worked! Thanks a bunch.

PK,
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

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

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

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

BTW: On the video driver chip, I found a nice packing of dust/lint against the side facing the fan when I removed the fan/heat-sink assembly. The packing was 3/16 thick on the fan side and wrapped around the lower side. It was quite dense.
The fan shroud on my V6305 has a slot in it that faces towards the chip/heat-sink. Dust had been blowing through this slot and collecting on the chip. I sure this contributed to the overheating.
The video chip is between the processor and the fan along the brass heat-sink strap. I’m sure the heat from the uP is affecting the video chip too. (Poor HP design? Not sure how I would cool it though.
)
