Phoenix
Williams, 1978I noticed the game has done this since the day I got it. Recently a whole bunch of switches went dead so I replaced both 7406 chips and that fixed my switch issue. However the game will still crash to game over mode for no reason in the middle of a game. It does jot always do it, but it does it enough that it is becoming annoying.
On a side note, I did the chip twist test and cannot replicate the issue.
measure the 5v right at the power board. Then go to the 100uF capacitor on the MPU board and measure voltage there. Then go to the 100uF capacitor on the driver board and measure voltage there. All should be within a tenth of a volt or so. If you see much voltage drop from the power board to MPU/driver there is a good chance hitting both flippers at once will make the CPU go into reset which drops you back into game over/attract mode.
The game is almost unplayable now it either picks game over mode or pics tilt mode. No consistency and no real specific switch causes it other than the fact that the flippers will never cause it. Since installing two tested and working 7406 chips it seems to be much worse now

Slam tilting? In attract mode a slam my laser ball makes no noise but it still resets the CPU. If you close slam during game play you get the tilt noise then back to attract mode. Check the slam switch out.
Can also unplug the two switch connectors on the driver board and see if it stops slam tilting. Then see pinwiki about closing switches at the driver board connectors. If you have problems doing switches at the driver board connector then the issue is on the board.
If you find a s switch leaning on a GI bulb or solenoid lug it will probably damage the 7406/4049 chips up near the switch connectors.
So I installed the driver board in my flash to see if it was a game or board problem. It is a driver board problem. How can I test the capacitors on the driber board? I shot gunned in two new 7406 chips with sips and that fixed the dead switches but now it goes crazy. All kinds of phantom detections. I'm going to shot gun in two new 4049s next but what else should I be looking at.
Guys does anyone know anything further on this really need to get this machine wrapped up. I replace the 7406 and the 4049 S I used sips so I could make sure that both sides got soldered perfectly no change the switch Matrix is still wacky and has all kinds of phantom switch detections in both of my Flash and Phoenix machines
Have to tried replacing the switch PIA (PIA2, IC11)?
You can also try these test ROMs: http://pincoder.reversion.ca
They will help you debug your entire machine. The switch test will help you.
UPDATE:
It was an issue with my flash pinball machine I was using for testing. It decided to blow a solenoid fuse and when that happens the switch matrix goes wacky.
Anyways I got the original phoenix driver board back in its game, with new 4049 and 7406 chips and SIPP sockets that I verified are perfectly soldered. I buzzed tested them all. It is still slam tilting and going to game over for no reason. A visual check of the switches show nothing.
Really need help. My yearly tournament is APRIL 6th. Same day as ohio show.
