Well - if you replaced every replaceable part with a known good one. Then the fault has to be in the non replaceable parts - the main board.
My guess: the processor or cache is damaged.
AFAIK every system starts up with caches disabled and at some point in the boot process the operating system activates the caches. So if the system boots and crashes right after that, i guess it is the cpu/cache
If you are in luck it is a bad solder point and it could be repaired easily. Try to put some pressure at the cpu or other chips at the main board and try to boot. You can also try ice-spray (CO2 spray) on different points at the main board. Every test with one point at a time.
If possible put the TAM in the fridge and when it got cold take it out of the fridge and boot it ASAP. (Attention - air humidity can kill the TAM!) I got some hard drives up with this technic for the final backup
. If the TAM boots when it is cold this could be a sign a bad solder point.
Just my ideas, bye
