I'm hoping someone can provide me some guidance...

Our WOZ standard edition was playing near perfect up until yesterday when I decided to see if I could tweak the Crystal Ball. The screen would occasionally scramble from clear images to fuzz. So I leaned in to unplug/replug as well as reseat the SD card. I also bought the Crystal Ball Mod so I removed it to see what might be involved in the install.

When I went to install reinstall the original Ball, the connector was very tight and I couldn't tell which way the connector went. While leaning in, I accidentally depressed the start button and started a game. I was able to connect the Crystal Ball correct and upside down. I did this while the game was on to see if I could get the screen working. During the confusion, I flipped the game on/off/on... several times to see if the screen would come on, not realizing this is very bad to do with this game. Crystal Ball screen came on, but was upside down RGB lettering. Not realizing this is correct start-up, that as when I got nervous, thinking the connector was upside down, so I reversed the connector.

Currently:

The game powers on, loads files, all RGB lights are flowing on playfield and the backbox display goes into attract mode,

BUT:

1) Crystal Ball and other features, Wizard Head, spots, etc have gone dark.
2) The Start Button no longer flashes, so I am unable to start a game.
3) All of the service buttons no longer work

I removed the service box cover. All of the fuses on the I/O board look fine and their red indicator LEDs are lit. The fan is running on the power board.

I called JJP service and was told that I may have done something to the I/O board. I told them that I would try to figure it out. They said if I can't figure it out, I can open a case and send the I/O board in for diagnosis and repair. I researched jump starting the game with the paper clip but Tech Support said that shouldn't be necessary because the fn is running and the part of the game is in attract mode.

Anyone have a similar experience or a possible solution? Thanks.

Thank you hippy ! Brilliant. I ordered those 1 amp mini-fuses because I didn't have any lying around. Came in yesterday. I replaced both on the far lower right corner near where the crystal ball plugs in and reinstalled the I/O board. Everything works... coin door buttons, start button, playfield features. All good. Would never had thought to look at those as they are well hidden and not near any of the main fuses that have LED indicators.
