Hello Friends i have this problem with my Esi-32, when i power on the sampler is giving me an error, where the sampler says: "An error occurred in this ESI-32. Please power off and restart..." what can 'be happened? not really used it for a month, but before this problem gave no error

Thanks in advance for help if possible

This error message is improper.

Check the power supply with a multimeter if the supplied voltage is correct.
Although I don't have any technical documents about the ESi-32 there have to be voltages that are close to -5V, +5V, -12V, +12V or even maybe -15V and +15V.
Check the power supply if you see a electrolytic capacitor that has a bulge on top of it or even a liquid coming out of it. If so, this capacitor has to be replaced.

Other possible source or errors might be RAM expansions.

If you have a second ESi-32 available nearby you can check components of your ESi-32 by replacing them with the same components from a second ESi-32.

Good luck.

This is a fatal error, I also think could be related to the PSU, the ESI has 5 and 12V + and- not the 15v.
good luck
