so i've been testing and buying new parts and nothing.
the MPU has been tested in a working cabinet....good
all new ribbon cables.
new fliptronics
new display driver
new driver board
new burned rom
still no sound and display.
playfield lights up and looks like its playing
led on MPU are correct.

where to go from here?
whats the least i can connect to the boards to test the sound or display?

i'll pay anyone who can help me with this...
i have no idea what could be causing this.

Obviously somethings not right, Please post a picture of the inside of the backbox with the machine turned on.

Middle LED on MPU constantly blinking and bottom staying on consistently? Has the game ever booted right with sound and display since you've had, or been this way since you've owned? What Rev is the newly burned game ROM and what Rev are the sound ROMS.

The one thing I see is that your connection on J118 looks really odd, I do realize its been hacked but with a 3 pin connector hanging off the side, I don't believe the connector is mated with the two center pins on the header. If this is true, the +12V on the pin to the right of the key is connected to a ground wire, this should have blown your 12V fuse on your power board. I don't see a connection anywhere for a color DMD, but if you have one, you will have no display and be unable to see the message saying to check your 12V fuse.

yes, the middle led is blinking.
this worked with the display and sound until i a loose wire under the playfield touched a live lug on a solenoid, then no sound and display. this was before all the new parts.

You have incredible attention to detail! Well done!

The red line on ribboncable from CPU J204 to 8-DRV J1 are both on pin26 ,that should work ok but I would swap them both to pin 1.
Can you check the ribbon-cable on the display, is red line on pin 1 ?

ribbon on display are both on red on #1 and i switched the other one so they are both on red...no go.

what is the bare minimum i need plugged in to test the display?

#17 7 months ago
Quoted from DTAC:

Everything, but disconnect fliptronic-board, sound-board (at least the ribbon cables from both boards)
J102 unplugged from PowerDriver to work safer.

Then check voltages on DMD-controller:

You wouldn't happen to know which wire this was, would you? Could be good information to have.

Is the fuse you replaced still good?

it was one of the optical sensors for the trough and yes the fuse is still good.

dmd is rottendog and all the test points are good.

Ribbon cable from CPU to Aux board is twisted.

Red tracer should be up on J204 CPU board side (this is correct in the pictures) and to the left on the Aux board (in the pictures it is to the right).

Good catch, but since its twisted on both sides it will work fine like that

Thats not what I see, I see the cable twisted only on one end.

Pin 1 is at the top of the CPU board connector which is where the red tracer is on the ribbon cable (correct).

Pin 1 is on the left of the aux board connector and the red tracer is on the right (backwards). OP - try swapping the orientation of the ribbon cable connector on the aux board end of the ribbon cable.

Ah, I see where the confusion is; pin one is actually on the bottom side of the CPU connector, not the top.

Thanks for the picture.... yet another error in the manual. The manual shows pin 1 at the top.
