Thanks John. I had been messing with the H Hold pot in the past but never tweaked it as far as I needed to go. All is good now, just need to do the standard color adjustments.

Check this out:

I've never been able to get good video from this monitor in the cabinet. So far on the 20EZ I've tested TR401, TR402, TR403- no issues. Did a cap kit and replaced IC401, HOT, D401, D403, D211, D212, TR204, and D161. Both vertical and horizontal sync pots adjust and affect the image- I just managed to get it stabilized in this video. The vertical sync pot and vertical size pots both had lifted pads on the remote board but I fixed those. Also, the vertical size pot was cracked but I think I managed to fix it since the size now adjusts. I should also mention that I feel confident in checking for broken traces throughout the board and all seems to be good.

I swapped out the game board with a DK board I purchased which was advertised as tested ok but I'm getting some weird sounds coming from it and it doesn't seem like it's booting correctly. Also, this was a Vs. cab which I pulled the harness and created a new one with the edge connector.

I'm now thinking that I need to rule out the monitor or the PCB as the issue by checking the board with a known working non-sanyo monitor, but I've never done this before. Anything I need to be aware of before going that route or should I check something else first?

Thanks!

I should also note that I'm a huge beer nerd, so let's trade beers if you're into that thing.

Hello there!

I've been collecting since January and watching the show really since then. I have to say that watching John's episodes have given me the confidence to go deep into the hobby.

So far, I've collected a few games.

Basement games:
Mortal Kombat II (first dedicated game)
Mortal Kombat IV
Street Fighter II CE Hyper
Galaga
Ms. Pac Man
Killer Instinct
Tempest
Konami 4-player MAME (X-Men cab)

Projects:
Pac-Man upright (full resto w/stencil paint job)
Pac-Man cabaret
Pac-Man cocktail
Jr.
Galaga (another one- rough cab but works)
Street Fighter II Champion Edition (z-back)
Super Street Fighter (Dynamo HS-5)
Mortal Kombat (waiting on side art)

I look forward to leaning on you guys for help with all this crap.

Holler.
Jim
