Yes, You are right.
But I don't know how to check Voltage during programming, because when I push "program" button it shows Vcc overloaded and no Voltage on selected pins.

No! The correct value of the Zener diodes is 5.1 V.
meteor80 - the correct voltage should appear for a short time. Connect the multimeter, and then press the "program"
If Xprog-m still follows its predecessor, Xprog, design concept, all those zener diodes are 5.6v
Hi i have same problem with original xprogm trying to read 9s12 in cas3 and ews4 at the moment, so i ordered tantalum capacitors, but did you guys who had the problem fixed it by changing them capacitors or not ?
Also what cause the capacitors to get damaged ?
Regards

first check these components
connection pin 9 (PE7) of ATMEGA64, ddtc143EVA, IRF7316 and LM317L

Hi, when you say check them what do i need to do exactly ?
I am just a locksmith using xprog-m you see .
Thanks in advance

You must do the test during reading or writing(with or without MCU,EEP)
5V - pin2,3,6,7 LM317l
0V - collector of DDTC143EVA
12V - pin5,6 IRF7316
Thanks

pins in lm317 maximum voltage 2.9
pins in IRF7316 MAXIMUM 10 V

I replaced LM317 and IRF7316 BUT STILL THE SAME PROBLEM
Any more ideas ?

CHECK AND REPORT
the yellow capacitors has shortcircuit. remove them and check them with a multimeter . in ohms you will see shortcircuit.
be carefully they have + and - . take a picture how you have remove them .
i have fix mine xprogm a lot of times and i am sure that know is better than original .
some times if i use chinese usb cable by xprogm not works . so i have found the appropiate to do my job.try different cable.

Check to see if it works on another usb computer.
had the exact same problem with reading hc912, recently moved my gear into a different room. so i used a different usb lead (not the original i was using), binned the used and got the original one back. All working well now!
