HD4850 Repair?

post #1 of 6
Thread Starter 
So I got a 4850 from a friend who said it died. When I looked at it I realized the heatsinks were all on wrong (Accelero S1). The VRM heatsinks werent mounted in the correct way, and the RAM heatsinks were mounted so poorly to the point where one wasnt covered at all.

Inspecting it I saw this, unsurprisingly. What I'm wondering if there's any way to replace a VRM? The rest of the board is spotless.

You might want to contact CL3P20 - He should be able to tell you if its fixable or garbage.

Ohhh... not pretty. Unfortunately I dont have the equipment required to replace such a component... although if you can remove it altogether.. there is a high chance the GPU will function without it just fine.

 

*even removing those is tough without an air-station.

Whats it really take to remove one? Because it's actually pretty isolated on the back, and I'm forced to assume that's where a lot of complication can arise

exactly.. what you would need is called a 'hot air station'.. basically a solder/desolder gun that uses air instead of metal/metal contact. Its really the only way to loosen the ground pad connection, which is anchoring it from the bottom.. to the PCB.

So if I were to find one off those somewhere, I'd just need to take off the bunk vrm and I'll probably be good?
I take it there aren't any alternatives to a hot air station?
