Sony comes clean on faulty 8XXX series Nvidia Chips!

[ScuderiaConchiglia]

There are people on Ebay who will repair the 8400, and make it better even.
Just be sure they are replacing it and not just doing a re-heat or melt.

Expect $150-200 for this service.

"make it even better"... How so?

They replace it with one without the solder flaws, but at least one claims they do something to make it run cooler. It's been a while since I dealt with it and I don't have any details other than it was a company in Europe doing it.

-turned on my oven (gas one) and set it to 385 F ~@200 C degree and i let it like that 5 min to get to the right temperature.
- after that i put the motherboard in the OVEN for exactly 10 MINUTES, NOT LESS NOT LONGER. (check next photos)
BTW, I PUT IT ON 4 PIRAMIDS MADE BY ALUMINIUM FOIL!

That technique, and a similar heat gun technique are know to work. But the problem is going to come back at some point. The issue still exists that the substrate and bonding material expand and contract at different rates and will again create cracks in the solder connections again later.

Also, once you have done this, professionals will not touch the board.

It's hard on all components.

Hi Guys,
I have a second hand FZ21s that was working fine..ish til yesterday. After some extensive reading, I can pretty much guarantee that I have a defective gpu. Why, cos the screen is blank and went wiggly green lines just before it died. Now I understand that Sony will fix this issue, but as i didn't buy this brand new(still cost £400), I don't have a receipt or anything bar the laptop.

So what i'm really asking is apart from sticking the mboard into my oven do i have a leg to stand on with Sony?

Any help/advice is greatly appreciated!!!!
thanks in advance.

It all depends on the build date of the machine. The warranty was extended from the original warranty date, which without the ORIGINAL purchase receipt would resort yo date of registration (if it was registered) or the build date.

OK, my VGN-AR590E shouted 1 long, 2 short beeps and the screen refused to light up. This laptop was seldom used but still died after three years.

Reminds me of the xbox red ring of death scenario..

There is no need to bake whole motherboard since problem lies just in underfill epoxy, so I suggest firstly just to heat up G84 chip up to 100 Celcius degrees. Result will be the same and you avoid to overheat other components on PCB.
