What are you guys using to bench test Sanyos?
I have been pulling out my DK Jr and using that but its a real pain in the butt. The power is no problem, run it through my bench iso and then through a variac to get it down to 100v.
My main question is how can I use a standard board to display on the EZ? I usually use a pacman board to test my monitors on the bench.
 
You can use an inverter. On some Sanyo monitors there is an inverter attached to the flyback cage.
You will need to make an adapter plug from the regular type vid plug (.156") to the Nintendo vid cable plug which is .100".
 
I tried using an inverter board but the problem I have is there is one red wire that plugs into it that not all 20ez chassis seem to have. Does anyone know what this wire does?
I already have a cable adapter I made up. I need to get the colors correct so I can get the monitors adjusted. Its impossible to adjust the colors with it inverted.

I believe that wire supplies +12V to the inverter pin 1. It will not invert without that wire connected.

Can anyone confirm that I can tap +12 to this pin to get this working. I know that alot of the ez chassis dont have that red wire but sure I can pull it from somewhere else.
Anyone have a 20ez pdf schematics that are actually readable?
 
The inverter can take +12V. I also uploaded Sanyo schematics for the 20ez and 20Z2aw to arcarc that are scanned quite clear.
 
You can tap into the chassis for the 12 V . Where R232 and R245 converge should be 12V.
Pin 1 on header AB on the inverter is where you need to connect it.
