So i purchase a 75200 mkesc to replace a 75100 and i just had the time to do 2 acceleration before it stops, the blue led wouldn't go on and i could not connect it by usb.
I opened it and powered it with a stabilized power supply only to find out that the part of the control card that give 3.3v and 5v heats a lot, after searching i found the fe Zener diode in short circuit so i replaced it and now i have the led who light blue but the powered voltage drops from 25 to 7volts and the 3.3 and 5v regulation still heat a lot.
Can somebody help me or give me a schema of the regulation please ?
