Hello everyone, I'm working on a repair for a Detech SSP-3100G FD. The microcontroller (PIC16F876A) shows a leakage (220 Ohm between VDD and VSS) and is overheating. I have already replaced the CMOS multiplexer (CD4051) and some other analog components, but I need the original firmware (.HEX) to program a new PIC.
Board Details: Marked as SP2-B2.
Serial Number: 040705.
I’ve attached photos of the PCB and the unit's front panel. Does anyone have a working dump for this specific model? Any help from senior members l would be greatly appreciated. Thanks in advance!
