Anyone ever seen this?
I had color in the boot up garbage previously, now just a lot of blue (replaced 1C today, possible I knocked something loose getting it back into the cabinet).

I'd swap the blue and red signal wires going from the game board to the monitor. If red shows up after than then fix the board. If it stays blue then check the monitor.
 
Monitor seems ok, looks like an issue with the board. All of the sprites seem to be appearing as an outline (you can faintly see the correct colors outlining the character, but you can see through the characters and anything else in the maze.
 
I just got mine working today and i think it would of been impossible to repair if the 2 boards were'nt split up on a bench. I had a similar screen like that today. I was only missing red vs your missing both red and yellow. Mine ended up being the plug running from the video board to the monitor. Was it working before you pulled your board out?
 
This game was completely trashed when I got it. All wiring disconnected or shredded. Leaves, nails, spiders, cigarette butts and a tennis ball inside. When I got it to boot it gave me a rom error, replaced the rom and this is where it currently stands. I may rebuild the cable and see what happens. The monitor itself seemed ok.
 
no i could not but i had yellow on my screen i dont see any on yours. Have you rulled out the monitor by hooking another one on or hooking this one up in another machine?
 
I hooked my Burgertime up to the monitor, monitor was ok. Tried eliminating roms and custom chips in Mame to see if I could match what it was doing, but no luck.
 
well i guess the next step would be to check the monitor cable for continuity on each pin .If it checks out ok then its definately the boards.
 
i'm thinking it's something on the board, just no idea where to check.
I was thinking maybe 4C (looks like R,G,B may come back to it at some point), swapped a spare and no change. Anything on here a prom with color data? Sprites are there but just the outlines.
 
gotta find it. I packed this hobby away 8 years ago. finally getting everything sorted out again. Luckily I am still on Bob Roberts' cross shipping list though.
