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

[morito]

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

regards

[Holtek]

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?

[morito]

hello

thanks for your reply but

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

no desolder nothing

regards

[Holtek]

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

[gadroulll]

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 .

[Holtek]

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.

[morito]

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

hi

which pins are need lifts to prove?

I don?t undersstand

thanks

thanks

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

what capacitor?

please paint in the photo

many thanks in the advance

[Holtek]

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

[morito]

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

regards

[Holtek]

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

regards

[Holtek]

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

[meteor80]

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

[unu]

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

i suppose it must be 5V6 zener diodes

[meteor80]

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.

[Holtek]

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"

[Zmann]

If Xprog-m still follows its predecessor, Xprog, design concept, all those zener diodes are 5.6v

[locks85]

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

[andrym3]

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

[andrym3]

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

[locks85]

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 .

[locks85]

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

[gadroulll]

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.

[amaflo]

Check to see if it works on another usb computer.

[maaxxyy]

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!

[cdex]

solved problem with vcc overload

[autocargo]

solved problem with vcc overload

Can you tell us more? Thanks.

[cdex]

i had same problem and solve it with capacitor change

[autocargo]

i had same problem and solve it with capacitor change

Have you changed them all? Same value? Electrolytic or tantalum ones? Could you post a picture?

[Holtek]

Replace six capacitors. Show in the picture.

[marcinnicram]

I have similary problem but I also change the MCU yesterday

[PierreTheron]

Capacitor change should do it if i read correctly

[abdelamjid]

hello to all
thank you for sharing

i have two xprog i need to programme Motorola MCU MC68HC11E9 4E28B

i see this vcc pin overloaded

xprog-m and xprogbox same probleme

any idea

best regards

CHECK AND REPORT

Why was the diode removed and where other soldered? Can someone tell me.

[karalaitizzz]

Hi to all friends. I have xprog m 5.5.1 . Always was good. But now when i try read tms i got low voltage error. With serial eeprom everythin good. Any solution?

[janusz21]

External pover 15v ?

[karalaitizzz]

Always was good with 12 v power. Now i just buy 15v power and now reads egain. Thanks

[Kalectro]

I had the same problem while reading an hc11c1 in-circuit. It was a bad selected pindata connection.

[mamanacusa]

i had same problem and solve it with capacitor change

you had them on opposite direction, or you had them in short circuit state?

[hassan197766]

The problem I had too was the reason it was a power multiplier
