A friend of mine ask for a favor to take a look at his HP TX1000 Entertainment Tablet PC blackout LCD problem. I have no idea on how to fix this until I found below video.
Instead of using bulb, I used a heat blower to re-flow the chip.
From my observation, there is a the gap between the GPU and the heat sink was join by a burned thermal conductive silicone sponge.
I replace this with an aluminum foil folded a couple of times to get just the right thickness.
After reassemble it back together and now, the moment of truth, Hey! it works! :-)
Thanks a lot jasonshay2. You really save my day.

Really nice and informative blog, keep it up buddy…Thanks for sharing.
What if I don't have a heat-blower, what are the other option that I could use to optimally fix my blacked-out LCD?. This article shows me that most repair shops charging so much for just a piece of work that I can do myself.
You can try to use 100 Watt flood light bulb just like in the video above. I believe it is sufficient enough to melt the solder ball under the GPU IC.
Glad to read this post of yours. I was trying to find solution for my problem. I had the same as yours. I did follow the steps and seen the video you put on your blog. It works man. Thanks a lot man. Hope you can have much more like this. I would visit your site from time to time.
Do you know if this technique would work on a Video Card? I have an ATI 4850 that I guess overheated and the memory now has problems so I get artifacts.
From an article that I've gone through, the main reason of dry/cold/cracked solder balls underneath a BGA chip is overheating. Of course the correct way of repairing it is by reballing. But it might helps with this technique but with no guarantee. In my case, the notebook is totally down. It makes no different if it failed to fix the problem, but in your case, it is still working. It might end up with 3 scenarios; fixed, still the same or not working at all. BTW, thanks for the "artifacts" term. I never come across to it until I've received your comment. Thanks to you and Google :-)
Nice posting, really good. I also have a blog but your blog is very much attractive from me.
Thanks for it....
