Hello,
I removed all the capacitors in the power supply (34 pieces ), they looks all normal: Capacity and ESR !!!
I will order new to replace them, I still have a second supply from the other.
@ Harry_22:
All the components are original !!!
If I start the CMU without the CMU-B68 the startup is normal, and afterwards I have the normal screen on the SMU200.
I do see during startup there is no CMU-B68 module installed.
I don't think it is a power supply problem, all the voltages or good, I started to test the power supply out of the CMU200 at first with a 820 Ohm resistor from b1
to ground to be shure it start normal and it did.
It would be nice to have the schematic from the CMU-B68.
I did remove the bad capacitor on the CMU-B68 to see what happens and to measure the voltage on it, but the capacitor next to it immediately starts to smoke
