Hello everyone,
I own an original Time Crisis 1 cab.
I fully restored the cab, but got a serious problem. The gun won't register and/or get the calibration target.
First I measured the voltage on the legs of the gun sensor. Initially I got 4.80V and shots weren't landing. I increased the power supply voltage to 5.2V and got 5.00V on the sensor legs. Still no dice.
I have replaced 3 gun sensors. Nothing new. I checked all cables from the gun sensor to the joint board, voltages in the external gun controller board, connections, etc. Nothing. I changed 3 tubes and chassis, and with a brand new 29" CRT I managed to land some targets on the screen. Unfortunately, the targets only hit the right side of the screen. I turned up EAT, brightness and contrast to extreme levels, cleaned the cabinet mirror. Nothing. Cleaned the gun lens. Still nothing. I was about to replace the original board set with a PC and a Sinden or Aimtrak gun when I tried to open the PCB cage and found a lot of dust and sand in the cage, coming from the fan. I cleaned all the backplane, 4 boards and the 2 daughterboards with compressed air, reseated all the socketed chips and reassembled the PCB. Once tested, after a week of failures, the shots landed on the entire surface of the screen! The game was fixed. I turned off the TEST button and had a bad surprise: the game was stuck in a boot loop! After a quick PCB check, I found out that the DSP board was defective. I opened the PCB cage again, cleaned it with compressed air and replaced all 4 boards. The result: the game worked like a charm and the shot registered all over the screen. The game is fixed. I hope my repair experience will be useful to someone.
