Picked up a Sega/Gremlin Astro Blaster yesterday, was hoping it would be an easy fix, No back door, interlock switch wired up but obviously not letting it power up, the seller said it used to work, yadda yadda yadda.
Got it cheap, so... Get it home, pull the interlock out, nothing. No marquee lights, no monitor hum, zilch.
Started checking from the plug backwards, took the interlock switch box cover off, and lo and behold, no 2A fuse in the Buss fuse holder. (Sorry, pic is sideways)
Woohoo! So I get a 2A fuse and wire it in, and now she boots! (Thanks Brien, for the link to a similar replacement Buss fuse holder!)
...to a monitor filled with this:
(Sorry, pic is sideways)
(Are these officially called "Jail Bars" or "Test Pattern," or what...?)
So... Not sure what to check next. It has 5 PCB boards in 6 slots, I am wondering if there are supposed to be 6, or if any of them are in the wrong location... Need to find the manual, I guess.
Any suggestions appreciated like crazy. Thanks in advance.
