Hello, thank you for help.
I check all parts around that burnt regulator, its all good now.
There are few more regulators on PCB actually two of them labeled 9B59 and i cant find datasthet for them.
Around one of them which is on bottom of the PCB is a bit of heating, its slightly heating but i cant tell exactly what it is as its on bottom of the board which is not accessible.
Those two regulators gives output of 3.6V which is a problem i think as i expected like 3V out from them to supply main processor, as i mention it require max 3.2V.
One of the regulator is for positive voltage and one of the regulator is for negative voltage as its converted over 7660 to -V
If anyone can tell what this regulator labeled 9B59 is, or if anyone can confirm voltage levels it would be awesome!
Thermal camera will help a lot for sure.!
I didnt notice heating on processor but for sure 180mA is a lot of current, fully working one should consume like 30mA, we have 6X more current here!
Any suggestions are welcome!
Regards
Milan
