Title: NXT 550, Code 1 Post by: Apache on November 16, 2012, 12:17:08 AM Hi Slot Techs,
I'm working with a I/O A-18886-01 which give me CODE #1. The CPU is good and cleared correctly :3-, all XU's IC's in the I/O are "know good ones" :3-. CPU clears in XU3 O.K :3-., then when the machine is restarted with the game... NO VIDEO, only "one boom, and then CODE 1" in the DS1 (sevent segment LED ). The problem is definitely in the I/O board, any ideas: burnt ic, resistor....? I'm thinking about Opto-isolator Thank you... |
