In case of exchange:
The diodes are often labeled with Fro xyz.
I recommend to change them all to ST ultrafast STTH.

Have a look at this site.

Hello everybody,
I'm Peter from southern Germany and new to this forum. I've stumbled across this thread because I recently got a broken TransTig2000 and I'm having trouble finding the issue:
When plugged in, the machine produces loud coil whine coming from the power supply board, and the displays won't turn on. I played around with the power supply board, and sometimes, when it is disconnected and reconnected while powered on, the displays and the corresponding control board come to life. Has anybody encountered a similar problem in the past or have any idea how to fix this issue?
I look forward to hearing from you!

Best regards,
Peter

Never had some kind of problem before.
Can you share a video?

Apparently I can’t upload a video on here, but I also can’t reproduce the weird behaviour from this morning. I’ve attached some pictures of the machine. The picture where it‘s working was taken earlier today. It seemed to be working and no coil whistle was on.
