Hello all, I'm having trouble with my DESW. It was working fine until Saturday. Trying to keep this brief, but want to be thorough.
Was working fine. Lifted the playfield to replace a bulb. Replaced bulb and lowered the playfield. No lighty-lighty when I turn on. Lifted the playfield (power still on), and the game went silent as I did so. Still had GI. Replaced bulb (bad LED) and the light powered on. Lowered the playfield and game fire back up. This was concerning to me as I assumed there was a short in the main harness running into backbox. It almost seem like the harness got squeezed between the playfield and cabinet when I raised the playfield, I had never noticed this before.
I started the game, shooter lane kicker not working (the coil which kicked the ball into the shooter lane, not the autolaunch itself). Game did a ball search and said 0 balls missing. Lifted playfield to see if I had somehow knocked the coil solders off or something. Game went silent again. Hasn't come back on since.
I've got all GI but no power to CPU or DMD. Speakers humming, so sound board getting some power. CPU test LEDs are blank. They flashed briefly yesterday on start up though, very quickly in succession, maybe half a second, and then off.
I checked all fuses and got continuity. I did find one bad fuse clip on the power supply board but it tested and seems like it's still got good contact. I'm getting +12 and -12 at the at the test points on the power supply board but only getting .7 on the 5v test point. Getting the same .7v at the 5v on the motherboard testpoint.
I'm not very good with this type of fix. Bad switch, bad coil, a quick solder here and there, I can do it. But this is above my pay grade.
At this point I am assuming bad power supply board. Perhaps I accidental shorted something with the playfield up and knocked it out, I don't know.
Thoughts, questions? I will try to be specific in any answers, but like I said, I'm not really very good with side of things.
