So while taking apart and cleaning my t1000s I heard something loose in the powersupply and something that looked like a little stone fell out
I took apart the supply and eventually found this mysterious part. It has clearly been very hot at some point and is all cracked to pieces. It has been very warm at some point in time Here is its cremated remains. Looks to have been about 8mm in diameter and about 7mm long with the connections at the round ends. And this is the board serial number I have no schematics for this supply so i can not look it up what i could be. I know where to find a couple other similar machines so one possibility is that i go and take apart another one and check what it is. Maybe i could even borrow a supply.

I am just suspicious of what caused that part to fail. And if it could have damaged anything else in the process. At a glance everything else looks fine at least, with no obvious signs of heat or burning

A little update:
Today I went and checked another, low serial number machine of the exact same spec/version as this one.
It had the same model power supply and it turned out to have the exact same issue! Same component was aslo burnt to a crisp and it already looked to have been opened up and fixed once at some point. The pcb even had a hole burned thought the board under the component. My board is luckily only a bit burnt. So still no luck in identifying what the toasty little component used to be

I find it curious the same component is burnt out in both machines. And in both everything else, at least visually, looks perfectly fine. So maybe a design fault of the supply itself? Or since both machines seem to come from the same place maybe something happened at that office to cause them both to go?

But for now, I now seem to be pretty much stuck in trying to repair this without any schematics
