Was fine but now I'm seeing double

[Doc Hollywood]

 I hope everyone had a good weekend. I did for the most part. Other than getting a revolution x up and running fine then cleaned the boards off and changed a few improper sized fuses and now I have a double screen going. The boards I connectors I cleaned were the sound board and gun coil board so I'm not sure what happened so I have a bit of multimeter work to do when I get home. Also the switching power supply that seems factory is loud as shit and I'm getting 5.5 out of the 5v leads and 14 out of the 12v lead. Is the couple of extra volts a problem? I turned it all the way down and I won't go any further. Plus it seems like a bit of the static noise from the power supply seems to be leaking into the speakers when the game isn't playing any audio and the static is a lot louder than I would like and it doesn't seem right. Any suggestions? Thanks guys. Doc

I know for sure that an extra couple volts can make games run poorly ,  I don't know about the double vision though.

I just brought home a big buck hunter that kept rebooting. Just as the lady explained that sold it to me

On start up self check I could see quickly in red text "VOLTAGE TOO HIGH"

The game would run for a minute and then reboot. 


Checked the PS and was getting 14v from the 12v

I turned it down to the proper 12v.   

Turned the machine on,  now in yellow text "voltage good" and no longer reboots and plays great


I would change the PS first if you can't turn it down to the proper 12v and go from there


Hope you get it goin !

Just thought of something else


I bet your monitor chassis is able to be used with standard Rez and medium res and you put it on the wrong spot of the board
Be sure the connector is on the correct spot on the board. 


My cruisn usa Frankenstein cab had a bad monitor when I got it. 


Tried a standard res chassis in it and it would work but had double vision.   It needed a med res chassis

Thanks for all of the help I appreciate . Ill give that and a few other things a try too. Any suggestions for a nice quiet power supply?

image doubling can be caused by incorrect resolution matching.

Got ya. It was weird though because it was working just fine then i cleaned a few connectors and replaces some incorrect fuses not its shit. I havnt had the time to get around to it yet but ill definatly give that a quick check first. Do you think it could be a Janna edge connector problem too? Ill take a few pics of the screen ASAP to give a better idea of what's going on. Thanks a million for all the help guys, I really appreciate it

Its possible the sync isn't getting to the monitor correctly or the monitor has for whatever reason decided to use a different frequency.

[Doc Hollywood]

Any idea on how I should approach it to check?
