Yes. The issue was that my brightness was too low. I looked at all the color drives but didn't think it was the brightness. When I adjusted the brightness, everything worked fine. The HSS kit is great.

Hey People, Ok. So. New sockets on Sound ROMs, Checksums good - no change New socket on RIOT, no change Replaced the opamps @3c & 4c - Bingo. Thanks for everyone's help! @blown23t @andrewb @tstone @lilypad19

Ok. well. It is what it is. I will start on this and report back in a few. Thanks

Jaydon, Ok, finally got a minute to work on this. on pin 30, on the tones test, the signal goes from solid high, to the fast oscillating - It does this on 5d,4d,3d,2d, On pin 37 of 2D, for the quad tone test, it goes from nothing (not high, not low, just dead) to low during the tone generation...

Hey thanks. Ok, I re-read my explanation and it is not very clear. Initial state: Performed sound test and 2D isn't working - single ping - no 4 quad tone I Swapped 2D pokey to slot 4D. Now, the 2D pokey works in slot 4D but slot 2D still doesn't work even with known good pokey installed...

Ok, Sorry about the delay. I followed your advice and found that the the pokey in slot 2d works in 4d. Also swapped a known good pokey from another game into 2d. So it looks like the pokey is good, but maybe something to do with slot 2D? When I re-ran the sound test I only get the very first...

Thanks. I followed your advice (page 3 of troubleshooting guide (sp225)) and here are the results: Sounds played on 5D, 4D, 3D. But on the 2D test I got no sound After this, I continued grounding, and got all the sound bytes to work-- Including the Darth Vader and other sounds missing in...

When I run the test I don't get the sound for rom errors if that is what you mean. All the beeps are high. thanks

On my Star Wars, I'm missing certain sound bytes. Noticeable on first wave of tie fighters. Darth Vader bytes are missing. On trench, Han Solo missing. And some of what Luke says. Thanks for the help!

Thanks, I messaged highscoresaves. I updated the description with my latest tests. check it out. Thanks!

*** UPDATED BELOW*** DK board works great, (first photos) then I added the Highscoresaves 3DK Multigame with remix and my green bias goes away (Second photos). When I turn the green all the way up, I still can't get enough green. I checked the green bias pot on the neck and it reads at 2.2k...

@andrewb , This is wonderful. Thanks so much for the detailed explanation! I have just a couple clarifying questions: So the +5, What is the min/max voltage you should see on this when it's not hooked up to the gameboard (to know if its a problem)? Could you please explain why we don't test...

Thanks, I re-attached the photo.

I'm going to be bringing up monitors on a couple different games: Star Wars, Tempest, Black Widow. I'm following @andrewb 's guide. So, I'm starting with the power supply: 034482-02D Since I'm not a EE, schematic isn't my first language, and I like using checklists, I'm making a cheat sheet...

Thanks so much for the reply. Do all my other voltages look ok, or where do you think the issue is?

@cdjump Thanks for this tutorial. I have a solar fox cocktail where the screen is just blank - not blue, but kind of static. Blank Screen Video I followed your instructions and these are my results: MCR II Sound IO 5v @ capacitors : I get 4.7v 12v @ tantalum caps: I get 12.3 Vbatt I get...

Thanks, Yes it was a sync issue. I needed to move the jumper up one and it solved it!!

Ok. Verified I'm on CGA on the Arcade SD board I adjusted Horizontal position and vertical position to try and get it to work, I could slow the scrolling a little, but no real change. Just to clarify. My video was looking great on the original pcb just prior to me hooking this up. Thanks!

Ok thanks, I will try that. Do you think there is a difference in output? My ms pac board I took out just prior worked fine with the monitor.
