JES, problem identified! The culprit is the control board......but i think its easier to just get a replacement board?

That is good news, it's very unlikely for a control board to toast, which is also why it would make sense if you found some very cheap control board, bitmain store is out of stock, so you need to get it from elsewhere, are you located in the U.S?

I open up another one, a T17 it had actually a heatsink off! there is some videos in Russian language, about fixing this, but i semm not to understand if the chip is replaced or resolderd? i should be burnt shortly after heatsink falling off, while in mining mode?

If the chip is bad then it needs replacement, but most of the time if the chip is toasted the heatsink won't fall, if the heatsink is off that hashboard is likely going to stop mining before the chip is burned, so usually, a heatsink that is off just needs resoldering.

Isnt there a way to just "short" the bad chip out and thus restoring integrety of the chain?

None that I am aware off, but let's see what the other guys have to say although I doubt such a fix is possible.
