I have done the repairs to the acid damage area, the board seems to boot every time now, the LED comes on and stays on.
All the playfield lights flash normal in attract mode.
But no buttons do anything, so i guess the machine needs re programing.
So i switch the #4 switch over on the MPU board and turn the game on, it starts to make a continuous sound, i thought i read somewhere that it is supposed to make 4 or 5 bing bing noises.
so then i press the advance test switch and nothing happens, i think there is a switch matrix problem as the tilt is in the same row and tilting the machine started my problems.
All the coin door wiring has been hacked but the advance test switch worked before these problems happened.
I have replaced ic38 a 3081 and ic41 a 4028 but this has not helped there is a 4042 chip i could replace next.
