@HKOCH Good day! In your case, the most difficult thing is to find the correct firmware. Google can help you find her.

@Gnome So I kind of told you everything. Can concrete questions is?

On the contrary, thank you for the motivation, as well as for your posts on another forum, which helped me a lot in the study of the inverter.

So as and promised a small report. I managed to fix the inverter by replacing the controller and some parts. The most difficult thing was to solder the controller back. Very small distance between the legs and soldering they are constantly closed. It was also difficult to find the reason for the lack of power on it and other chips, but it's probably my fault. It turned out that the replaced power supply assembly was either defective or i overheated it during the replacement and therefore i began to check it again last. Loading the program into controller was easy enough. I took the firmware on one of the forums mentioned in this topic and using the USBDM freescale programmer. Loaded through the provided connector on the main Board. If anyone needs details ready to answer.

Thanks Weber for the answer. I read your posts on another forum and know that you are very well know and versed in the repair of inverters PIP 4-5K. I'm not saying replacing the chip will help, I want to try it. The symptoms are as follows. Resistance to supply +5V to about 4 Ohms. After unsoldering the legs of the chip power supply, the power resistance has become much greater. Filing on the soldered legs power chip + 5V saw a strong heating of the chip body. Your URL is correct.

Okay, I see a lot of skeptics here. But then what can you say about the firmware referenced in this topic? Found the link courtesy of Chris Hobson This firmware is encrypted or not ? Ver0242.s19

Thank you, Colombo, for your sincere desire to help. I will use your hint and try to program a new chip via JTAG ICE II or equivalent. Even found a forum on washing machines. My chip is also used there and people program it. I will study. In the meantime, ordered on Aliexpress chip and waiting for delivery (20-30 days). I will share the results here on the forum.

Thank you for the detailed answer. Let's think. For information I will add that this inverter has MC9S08AC60 chip installed on the main Board and does not have а Control Card.

Hi All. I have an Axpert KS 3K. His chip U1 burned. Can I replace it with a similar one and re-flash it?
