The more modern version of this can be found in the local PC shop.rubber_jonnie wrote: ↑Sun Mar 01, 2020 9:00 am Manhandling the board is enough to shift the MMU/GLUE/BLITTER in their respective sockets, as there is enough flex in the board and sockets for contacts to shift and either fail or work again. We often think of electronic faults immediately, but also need to consider the mechanical properties that can cause faults too. Assembly/dissassembly can be enough to break a machine.
There they pull out the PCI cards and put them back when the machine doesn't boot, put them back and call it done.
In most cases the BGA chipset has some loose contacts and you can wait for it to have the same problem again…
Good call on the PLCC extractor, trying to pull a PLCC ic from an old socket without the correct tools will end in a lot of de and resoldering
