good afternoon, I have a problem where the game lights do not light and half of the board coil do not work.
the problem is in the CPU, I already tried the cpu board of the machine in which I did it for another that was working and does the same.
so the problem is on the cpu board
some way to test the signals coming out of the cpu board and going through the ribbon cable that connects the cpu board to the power drive board
pull out the square assic en set it back and press all the ic's in the sockets that can be somethimes the problem.
If it doesn't work you have one problem les.
thanks,
I already took it and went back for the microprocessor and the game ROM and it remained in the same.
It's talking about getting up and coming back for the asic chip certain ?
Is the game booting up? If yes, what does the test report say?
First place to start would be checking fuses, remove at least one end of each from the holder and check with a multimeter.
thanks, Yes, it's initializing the game.
the fuses are good, I checked this before taking the cpu board.
Quoted from pedroborges:I already took it and went back for the microprocessor and the game ROM and it remained in the same.

This has a high probability of correcting the issue, BUT you must pull the board from the machine and place it on a hard flat surface or you risk cracking these tiny runs on the board.
