xprog m vcc pin overloaded ?

[el_futte]

hello there i try to read out a motorola hc912d60 but i get this erroer every time.

vcc pin overloaded tjek vcc pin connection.

any idea ??

xprog-m v 5.0

hi

I have the same problem

there are any solution for this

vcc pin overloader

any idea is very apreciate

many thanks for all in te advance

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?

5V - pin2,3,6,7 LM317l
0V - collector of DDTC143EVA
12V - pin5,6 IRF7316
Can you please mark the points on the picture ? i cannot find out what do you mean, and forgive me for that .

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

i suppose it must be 5V6 zener diodes
