Reverse Engineering help for Advantage 900 Remote Operator


Recommended Posts

I'm looking to repair a few burnt-out IC chips on the main PCB of a Advantage 900 Remote Operator, but due to them being burnt out, I can't figure out what chips they are. Everyone I've tried to contact either doesn't have one I can reference, or its in storage and they're unwilling to take it apart. To make things worse, the only schematic I have been able to find of it is too low quality to read any of the text. 

I've attached an image of the PCB, and an up-close shot of the burnt chips. If anyone could help me figure out what these are, I would greatly appreciate it.

My educated guess would be that there may be “unrepairable” PCB damage, but I can provide schematic and PCB layout “fragments” for the burnt section and periphery. If you need further detailed documentation, factory authorization will be required. In that case contact ODT-Support@Omron.com with your request.
