Hi everyone, first time posting in here.
Recently I played my game for a few hours and the dmd start to get glitchy until it just wouldn’t come on, and then the game wouldn’t power on.
I reseated the ribbon cable and this let the game boot and the dmd right back up so I ordered new ribbon cables from Marcos.
Put the new ribbon cables in and the game now boots but the dmd is really displaying different random sections on/off very time I turn it on.
I tried to mix and match old ribbon cables with new ribbon cables until I settled in the new set. This time I went to power the game on and nothing.
I unplugged all the ribbon cables except from power to cpu. Fired right up, added the fliptronics board and sound board and everything works fine up until I plug the ribbon cable from the fliptronic board to the dmd board. When I do that, the game won’t power up.
The ribbon from the power board to the dmd board connected still allows it to turn on.
Regardless of the combination, the dmd still shows intermittent. I left it on for a while and played some games, looks like some of the dmd woke up a bit and displayed most of the dots but still not clearly.
I’m about to see if pushing on the U9 chip affects it tomorrow. Also if there are cold solder joints under the connector for the ribbon cable on the dmd board.
Any other thoughts??
