Iprog+ clone Repair

**PSAcars** · 3rd January, 2021, 08:52 AM

Hello to all. Here I have made power board to work on 100%, read my post on this thread. You will have to remove one diode ( on original iprog there is no such diode bypass the inverter circuit, and change 4-5 resistors in inverter circuit ) look here:

Definitely great work. I'm wondering if an external power supply can be added to the iprog to achieve same effect. The power supply with the hard epoxy can't be reworked.

Thanks for sharing your work

Hello, can you share what you change and with wath components please, tks

My Iprog Power Module, (Tested)

It can fit on China Clone and Ukraine clone

There's a third of pin connecting the main board to the power board. Can't see that on board from hcip. I guess she simplified it.

The 3rd Pin on Chinese clone is only a guide not reverse the connection to the main board when you plug this power board, so I marked it which side is correct when plug it on the Chinese Clone main board..

Thank you hcip. Nice to see you back. Do you need an oscilloscope to read the different voltages from the power board? Or are the voltages constant on those pins?

An oscilloscope is not the best tool to test DC voltage. A multimeter on Voltage position is the only tool you need, as well as a continuity tester and the schematics in order to locate the components.

Thank you for your help.

With a scope it would just be easier to measure instantaneous voltages. I have tried to use the schematics that came with the iprog but the parts do not correspond on the board. Kind of weird why would a cloner change something that works to something that doesn't. Makes no sense just to save a few cents.

Baffles me really.

Schematic from Iprog doesnt help mate.
as you can see on my Board, I make some modification, Some part are replaced, and value of resistor also changed
Following what inside the original schematic cannot deliver the stable voltage because of the parts manufacturer difference

you need to Get a reference from the datasheet of Part to get exact and Stable Voltage...

Would you be so kind to share the parts that you used?

And me who thought using ohm's law to get the required voltages by adjusting resistor values.

Hello c

an anyone tell me the value of the small missing capacitor in the circle? Thanks

Very Bad Regulator Board. too many missing part.
Do it with your own risk.
if you are not familiar in electronics then Think before you proceed, The output of inverter IC may raise up to 50Volts and may damaged your Atmel Proccesor

Thank you my friend for your time and patience. I replaced the parts apart from the coil.

I will look for one. It's a non working iprog so just playing around with it. It's like a piece of puzzle for me. With all the time i spent buying a new one would have been much cheaper. But can't help it the satisfaction of fixing something takes over.IMG_20210718_161953.jpg
