P-6831FX Nvidia chip failure REPAIRED!

Hi guys,

Just thought I would drop a note about my success this weekend in my attempt to repair my P-6831FX. The video went out last week, and after reading numerous successes with baking boards in the oven to repair the Nvidia 8800 chip (or using a heat gun, not smart, doesn't evenly heat the whole board!) so I gave it a shot.

I'm back up and running thanks to a great teardown writeup on here. Hopefully I'm set for another 2.5 years, but I know I'll be opening it up to clean out dust a lot more often now.

I have heard that baking is only a tempory fix, i.e. usually a week or 2 at best.

 

I read an article where it worked for a guy for 3 months and then he baked it again and it continued to work. Any way it doesn't sound permanent which is a shame.

 

Interesting, Aaron. I'll be sure to leave another comment if it fails again. If it does I may just bring it to work and remove/reball/reattach it (it's nice working in PCB design/assembly!)

 

Congrats on the fix!!!

It won't last forever but there is nothing wrong with re-baking ;D . I baked my p-6860 in the beginning of January this year, since then I have re-baked twice.

The first one lasted 2 months, the second lasted a month and the third lasted 5 months and is still going strong though I have had waves (about 1-2 days, then everything goes back to normal) of random shut downs.

Differences in the baking were temperature and time in the oven, on the last bake I turned the oven up to 280 C (don't quote me on that) which is the highest I had ever gone and left it in there for 10 minutes. This last bake was also the most successful.

Oh and I game hard, sometimes the laptop will be running WoW 6+ hours at a time.

 

I wish I knew about baking when I had my HP DV9000, it could have lasted me a couple more months. I just tried my dead P7808u and was not successful. Oh well I guess.
