Hikaru issue

Yeah I've been in touch with him, what a load of crap this board is. I have it working for now, I jammed a piece of plastic exactly 2.5 inches between the gpu sink and the lid, but that is a literally band aid on the situation it seems
 
That's what I've read you have to do but either nobody has the experience or equipment to do it anymore.

I reball and replace these types of packages at work but there is no way I am spending $3000 on the low end for a piece of equipment I would not have enough demand for to pay for itself

Yes this is all correct. Problem is loose BGAs due to a manufacturing issue. Once these come loose, you most likely will not get them to reseat due to oxidation of pads on IC since they were never tinned. Don't try to remove heatsinks or you will probably tear IC in half of cause severe trace damage to pcb. Not like it matters at this point I guess. Its not a thermal problem. You need to start thinking about either replacing the CPU bd from a local sale / vendor or just collect ROM bds to swap onto you PH unit. I say local because you most likely will not be able to purchase one and have it shipped without breaking. I was the last one taking these sets in for repair. I recently stopped because every one one for one was breaking in transit.

That's most likely why it's rather hard to. I actually watched Ken try to tin a chip from a Hikaru and it would not hold solder at all...

I used to just pull another IC and reball it if customers was damaged. But its super time and patience consuming to do this. A lot of times when you clean the pads on IC, the pads come off. Happens on pcb too but that I was able to repair. Problem now isn't replacing IC. Problem is the other BGAs will also come loose in shipping. I stopped doing these about 1.5 years ago when I could not get them to ship in or ship back with out further damage. I have a friend that has some POD Racer sets he can sell. Fingers crossed on shipping though.

I just don't understand. Are you using lead free solder or something.
