Many thanks for your comments. You can get in touch with Mr.Jestine Yong, who would provide your my contact details. As we stay in the same state, this would make intercommunication better.

You are truly a genius in all aspects, your patience is remarkable, I learned a lot from our articles, not too many such geniuses are keen to share their knowledge, its these kind of out of the box thoughts saves us.

Thank you and keep us this great work.

May I contact you for any questions when end up in such dead ends?

Many thanks for the tips and comments! Inserting another unit and interfacing with the other two ICs cannot be done without getting the original codes. Anyhow, I am not familiar with such programming either! Shall see the link and try to learn!

In reply to Albert van Bemmelen.

The first symptom was that none of the controls were working. The IC was getting hotter than the other similar one. He never had a circuit diagram nor did he have an oscilloscope. (Poor guy died later on due to cancer!) He too did the basic things required to confirm more or less that this slave IC was defective. The unfortunate thing was neither of these parts were available, nor was there a similar IC used equipment in stock. Many thanks for the time you are spending to ponder over various aspects of this case. Shows how involved you are and make people like us to be more alert in many angles!

I think you could of gotten all the functions going if you had used a picaxe controller and wrote the program to do all the functions. https://picaxe.com/
As usual you go above the call of duty with this repair.
