Post-cap kit problem
« on: May 05, 2009, 11:46:54 pm »
I tested my sanyo 20EZ monitor that I installed a bob roberts delux cap kit on today and ran into a slight problem.

I have been working on the cabinet and the board and power supply and wiring is not inside the cabinet anymore so I hooked it up for a quick test on my bedroom floor. When I turned it on the monitor crackled with life as it should and I can see the neck glow, but there is no picture of the game, just a bright white screen. I had the speaker on the floor the first time I tried it and it did not have any of the game sounds like it should once I tried to play it blind.

Does a bright white screen set off any alarms to you vets of this hobby?

Because the game didnt play blind, I'm hoping it is just a grounding issue, but I dont think I can get this lucky.

I will post a picture of the screen tommorow once I get it off my camera if that helps, but I just wanted to see if this sounds like a problem anyone else had with out needing a picture, and always thanks for all of your help.

Sounds like you screwed something up - but not catastrophically.  An EZ will come up with a white screen if it's operating correctly because it's set up for inverted video.  Sounds like something on the board side.  Did you hook the power supply up the right way?  What game is this?

I agree with Peale...... since it's not playing blind or otherwise, double check everything on the game board side of things before being too concerned with the monitor image.

Sounds like your monitor is ON, but not receiving anything.

Yeah it was a stupid rookie mistake, in the rush to see if my monitor was working I plugged something in the wrong port, which was a power cable so Im glad I didnt fry the board once I set it up correctly the game fired right up and looks great!

Thanks for all the help guys!

Was it the one that goes to the video board?  If so, don't feel bad; I did the same thing.

Yup, thats the one. I had the board leaning up against my bed and didnt remember there was a plug on the back of the board.

I guess that is how you learn though, just glad it didnt cost me anything like most of my mistakes do.
