Is the processor is desoldered? XPROG-m Output-VCC supplies only the CPU? and aslo other components? What happens when the programmable processor is powered from external power supply?

hello

thanks for your reply but

is the same problem conections external power or usb
the same error

no desolder nothing

Lift the pins that connect to the programmer. Connect the external power supply (13-15VDC) to XPROG-m.

1:check other eeprom if working
2 if yes you have a damage eeprom and not xprog
if no
3 open the unit and check by your hand which component get hot.
4 you will find a yellow capacitor and desolder it
5 check knoe if xprog read the memory
6 replace the capacitor .
7 NEVER CONNECT THE CLONE XPROG WITH POWER SUPPLY .

NEVER CONNECT THE CLONE XPROG WITH POWER SUPPLY .

Why not? Explain! When the USB output current is too small, it is necessary to connect an external power supply.

thanks

but the eeprom is good, the same problem is whit mcus

what capacitor?

please paint in the photo

many thanks in the advance

Check the eight diodes Zener. Do not have short circuit?
Check the voltage marked on the picture.

hi

Holtek many thanks for your big big big help

thanks

the problem is a condenser , see photo is bad direccion solder.

but the programmer works well 1 year whit condenser solder in this direccion. electronics mysterius


NOw my programmer not read good in hc05 and 9s12 , and not read tms botloader error

read good but sometimes verify error.

what is the new problem?


many thaks in the advance

Wrongly soldered capacitor hehe Replace it with a new one. The best solution to replace all tantalum capacitors for electrolytic capacitors.

Have you tried several times to read the TMS? You tried to read several TMS?

[morito]

hi

what ref is capacitors electrolitic?

change all capacitors?

I read tms immo opel and vag and read good whit usb and power suply 12v in 2 programmers

many thanks in the advance

Do not have to replace all. Replace the most important, marked in the picture.

Hello.
I have also Vcc pin overloaded.
What is the label (voltage) of Zener diodes?
