Amiga 1200 floppy disk drive weird issue

Friendly people I have the following problem .. I do not know if I raised it before here ... It turns out that the drive of the amiga 1200 stopped me walking, but it is not the floppy disk but something on the board that manages the floppy disk drive .. when the I click the floppy disk works fine .. but then a few seconds pass and it stops walking (it's as if it will heat something) and after that the time that the 1200 is on. It stops me walking .. it flashes the floppy LED of the reader 3 times and return to the violet screen of insert a disc .. my board is rev 2b, any idea ??? I tried cables change of floppy disk to measure voltages resolving pins that are related to the floppy drive and nothing ... It achieved the same result I made change of capacitors bought exclusively for it with exact values of voltage and amperage. I was walking with the floppy barbarian .. it was one day to stop working properly, any suggestions? thank you !!

Do you have a gotek nearby so that you can try to get that working?
Just to narrow it down..
