Hello everyone. I'm wondering if anyone knows what the part number of a replacement photo transistor would be on the guns of Lethal Enforcers II? I do have some of the replacement Happ guns that I know I can get to work. But I'd MUCH rather fix the original guns as there is nothing physically wrong with them. I'm fairly certain it's just a problem with the photo transistor. But if anyone has any experience fixing these guns instead of just replacing them the info would be much appreciated. I tried doing a few searches online and didn't come up with much. I did find a video on youtube but it doesn't have the same boards that mine has (I think it's the replacement gun boards). I will use the replacements if I have to, but I'm REALLY hoping to fix these.
