I have a Multia (VX40) that developed intermittent failure to POST, and had a very hot 3.3V rail. It seems this is because a capacitor on the system gets sheared off the board by a metal locating peg when the board is slid out of the chassis. (This doesn’t seem to be related to the common failure of the 74F623 bus transceiver on Multia systems.) Said capacitor is at the front of the system, by the screw near the audio ports. When it gets sheared off, it seems to also possibly damage the traces.

It seems this is a tantalum poly electrolytic, 106 at 35V for 10µf. I have not yet ordered a specific replacement; when I get around to replacing it, I’ll update this post. Per someone I know who replaced the part on theirs, they recommend holding down the component in place with glue and opening the top case when sliding the board out to avoid future damage.
