Ariston Hotpoint KIB633CE Induction Hob repair assistance needed

[janos6662000]

Hi
I bought a faulty Ariston Hotpoint KIB633CE Induction Hob
It has 3 induction zones, 1 is working and 2 not.
I was expecting a faulty IGBT. Indeed, that was faulty, but unfortunately it also has some damage on the driver part. The second IGBT on the same microcontoller does not appear faulty, but that zone was nto working neither.
I attach some pictures.
Right now my biggest problem is, that 2 of the IGBT drivers are not looking good and i cannot find what type is it.
They are SOT23-5 package, pin 2 on GND and pin 5 on output, connected through a 27Ohm resistor to the IGBT gate.
They are marked 100TP as on the attached picture.
Also, i cannot find anything on the microcontroller, marked SH16MVTJ
This board also comes in a 4 zone variant, on my board the fourth zone is simply not populated.
Any schematic, tip, or repair advice is welcome.

you need to give it a good clean and then a close look

OK
I made some progress, but there is still lot to da
I attach a photo of the board after cleaning and another one after removing some parts.
What i know for sure: resistors R108, R109, R40, R41, R64 are faulty and i will change them.
Capacitors C2 C25 C31 are damaged and C1 is short, so i will replace. These all seem t be 100nF
Problem is with the semiconductors.
Diode D12 had some damage around it, but i unsoldered it and looks OK when tested.
Diode D24 is even stranger, because is already discolored, but even so looks OK tested.
If i know what type is it, i could replace it, but no idea how to find out.
It looks like the Q20 is a voltage regulator. Unsoldered measures like the good one on the working zone, so i may keep this. Again, not sure about the part number.
Problem is with the U2 and U4 chips. These are IGBT drivers but i cannot identify them without a schematic.
Pins are like this:
1 = IN
2 = GND
3 = EN/NC
4 = OUT
5 = VDD
Marking is 100TP, like in the attached picture and are SOT23-5 case

Please help if you can.

Best regards,
Janos

Thank you very much, this is a great find!
I will order some and test, i will get back with news.
