Do u think using heatgun will b better?? As I know, The problem is not just the contacts between the GPU and the motherboard, the problem is even the contacts between the real chip and the pcb of the GPU.. Thanks for sharing this tip! In our computer repair shop Brooklyn NYC, we have a lot of clients, bringing on for repair laptops with Nvidia chipset failure. All I need is the place where its a bad wire connection or chip nvida that needs help. I left it like 1:

To make sure there is no cool air coming into the case through the bubble wrap, I closed all air vents with sticky tape. When solder becomes molten the chip as it cools sucks in dirt and contaminants from 61137 board.

Guess what, it worked but the graphics is still blurred. Plugged AC power, turned it on and let it overheat itself.
Now I install new windows 7 and it works fine. The proper thing to do as someone stated above is to pull the chip, clean the pads and the board, re-ball the chip and re-apply directly to the board.
Thanks for this tip. The white screen could indicate 637 connection between the video cable and LCD screen. This is much beter than the oven trick!!
I have no extra parts to test anything with, and i have no way to test an external monitor with the lack of the ports needed to do so.
Unplug the AC adapter from the wall the let it cool down do not move it for a while.

What do you think the problem is? I am far from videl computer genius and found this all very easy. If you have a question, please create a new topic by clicking here.

I wrapped the laptop excluding the monitor side after turning it on of course without HDD and battery.
How to fix HP video problem
In the morning I put the hard drive and battery back in, turned it on and voila! Any way to re-solder it permanantly?
Adrian October 28, Add me too the list of people for whom this solution worked!!! Since repair, it runs perfect.
This procedure is called re-flowing of BGA soldering. I guess that this method will fail one day, then I will have to chuck the thing in the bin.
Thanks for this jewel! Message 1 of 2. The reasoning behind the procedure is sound, and I figured that I had nothing to lose by trying this, as I had no display anyway! Please remember the is a law suit against HP regarding this issue. You can better investt 3 — 4 hours in videeo apart the laptop, and do a oven or heatgun reflow heatgun beaing the bestit will satisfy you way more with a good working laptop.
Hope it lasts or at least will work again in the future! Will Jackson November 7, One hour later after towel wrapping and cooling off and viola!! Maybe can squeeze another year cv of the laptop. Its motherboard power regulating IC Out put giving only vdeo.
