Hi all! I am super new to pinball machines and how to work on them. My DE Star Wars machine was recently purchased and in pretty great shape. We have been playing on it for a few days just fine. Tonight I factory reset the machine and changed it to free to play for home use. We played a few games and then turned off the machine. When turning it back on a few minutes ago it lights up solid (does not blink or flash like usual), the speakers have a slight hum, but no sound coming out, and the DMD shows a row of lines/dashes/dots (see pictures). I have checked the fuses and all look good. Has anyone else experienced something like this with their Data East games? I honestly have no clue where to start with diagnosing what it could be. I check all the connectors in the backbox, everything inside the backbox and cabinet looked and smelled the same. I knew that pinball machines break, but definitely was not expecting to have problems with it within the first few days, welcome to pinball life.

Any advice would be appreciated, I am not really sure where to go from here and feel like a complete noob.

Update: Now the machine powers on and still hassolid lights and no sound, but the DMD is dead. It doesn't light up at all and is completely black.

After turning it off and on again the DMD stopped working completely. The sound is still gone and the lights are lit solid on the playfield. I am suspecting that it may be the power supply after rabbit trailing through posts on the forum. There is a little discoloration and possible leakage of the C2 electrolytic capacitor, but not 100%. Also, the blank, +5V, and PIA lights are not lit up on the CPU board.

That is what I was assuming, thank you for confirming. I'm now debating replacing the whole power supply board or trying repairing the current one. This game has quickly become the house favorite and I see it getting much more use that the other one we have.

That is a bummer about Rottendog. I've noticed that a lot of places are on back order for a replacement board on other sites also. I'm always a little leery of random Ebay purchases, but that may be the route I have to take. The search continues!

I purchased a DMM and it will be here soon so I can diagnose further. I will definitely take a look at the the fuse clips and fuses with it. I looked up repair people for Pinballs on Google and it was not much help. Is there a way to look up people/companies on Pinside that are local and do repairs?

Thanks!

Oh wow! Thank you for all this info, this is super helpful!
