anyone have a clue as to whats up with my vision wild star red white blue bonus spin, change the battery in upper lcd , have good working mpu board in the machine
everything plugged in , machine does it test and that hangs on the upper screen initializing please wait ,i checked the chips on the main cpu the check sums are correct this is the 1st vision i have ever worked on so not sure what direction to go with , large card is plugged in the top as it was there when i got it door opitics are by passed
im at a loss on this machine i hate to tear it apart and make a run of the mill s-2000 out of it

Have you tried a full clear?

You could also turn on the machine without the main mpu installed to see what the top box does. I seem to remember that it will load independently.

Perhaps even try a different mpu board just to double check. A bad board will definitely display that same error. Double check All the eprom legs are seated and facing the correct direction- silly, but Iâ€™ve done it.

Good luck. Would be a shame to lose the vision part

Can you can me what chips you have installed exactly?

Also, does your LCD boot up like this or no?

I need to see what is happening with yours...make a short video please?

You may need to install a jumper behind the RAM memory sticks next to the LCD invertor board on the LCD to see wthe boot up sequence.

Here's a boot up sequence with a NJ Version chip....they're slow...you get all the dots instead after "Please Wait...Initializing" message....>>>

I had a similar situation recently. Machine ran fine when I switched it out to a regular S2000 game but was stuck on the initializing screen on the top monitor when changed to a vision. Ended up being a bad power distribution box for meâ€¦

Yes...that can happen too....loses communication between the topbox lcd computer and the machine's MPU comm is on the three gray wire harness coming off of the power distribution panel box to upstairs.

The other important harness, of course, would be the ribbon cable from the power distribution panel box to the MPU.

If there's anything wrong with those (Loose, bad pin connection, oxidization, broken internal wire, etc.etc.) then the MPU never really "sees" the card up in the topbox lcd unit.

It won't finish the "Initailizing" part of the boot-up sequence.

The power distribution panel box is the one that has the ribbon cable - this box distributes COM signals as well as various power.

The power supply is the box behind the reels...that one is probably okay since everything is powering up and only deals with power.

You may have a COMM problem (which could be chip related), rather than a power problem...

yes that is the box i was going change i know my power supply behind the reels is good tested that on another machine , thanks for clearing that up
