ATI HD4870 dead?

post #1 of 14
Thread Starter 
Hello,

I have owned an ATI HD4870 for quite a while now, but after installing a new cooler, it decided to go rogue and die on me.
Here's the deal
When i start up:
* no POST
* black screen
* seems to be deader then dead.

But when i install a temporary card i can see the card using ATIFlash,
it shows all the information of the 4870 without problems, which indicates its not entirely dead yet.
Is there any way to bring it back to life? or should i give up and throw it in the trash.


Thanks,
AeroXbird.

Try with the original stock cooler. You might have missed something when replacing the cooler.

If it's dead is dead you won't be able to see anything with "atiflash -i".

I actually tried putting the original cooler back in, but that didnt work either.
Weirdly enough it does simply show up with atiflash -i

Well if its dead....

You can try to reflow the board with a heat gun. It actually works alot of the time. Just take the cooler off, cover the caps with tin foil and heat it up. Let it cool, put the cooler on, and pray.

Would it suffice to try it with an oven?
I did this with my old 4890, and it seemed to have worked at the time, altough i believe i did it wrong.

The oven will work, the heat gun method is less harsh though.

I see, do i have to cover anything on the PCB with aluminium foil after i strip the card?
or can i simply put it in with balls 4m high of aluminium foil underneath?
