I just got a TZ via NAVL and when I plug it in and turn the machine on I just get random pixels on the DMD and the game doesn't do anything. When I press the flipper buttons I see the little lights flicker so I presume "some" boards have good power, but I'm not sure what the specific course of action is here. I took the DMD out and tried to make sure it was attached firmly, and also flipped up the playfield and tried to make sure everything looked cool and no connections had been jostled. Anyone know what's the problem with my machine? Like 20 random pixels in different locations when I turn the machine on.

no boot chime, I tried looking for missing ones but is there some list I should be walking down of connections? The only wire that's weird is some green one right at the bottom of the backbox but I think it's an extra ground?

The power driver board has 4 red lights. I don't have a meter. No other boards have lights on in the backbox except for the top right board has one light on.

Thanks everyone for all the help, I got big70 from oldies but goodies over to my place and he fixed my issues right up. One fuse, one bridge rectifier and one cap were out, and he took off a board and replaced the connectors for me. Freaking amazing guy, since I have no experience he looked like a miracle worker. Learned a ton, I recommend him for anyone who needs any help in the austin area. I still have one tiny connection to sodder and a coil to replace but the game plays and I am soooo happy. Thank you oldies but goodies!
