Thanks for looking in. So today my WOZ would start to boot, computer on, fans on, but never get anywhere. It would just flash a little box center screen and black out, then repeat over and over. The screen never comes up. Started looking around and found if I shut the monitor off the game boots up fine, everything working but the monitor. Turn monitor on, the LED turns green on the little monitor board then turns red and down goes the game and the monitor. Monitor won't stay on now either. It was in a state of always on of course before I shut it off and let the game boot. Any ideas what I could look for? Check all the connecting behind the monitor and they all seem fine. Appreciate any help and thank you in advance.

Do you have another computer monitor that you can swap it with (just the connection not to put it in the back box. That way you can see if the monitor is the issue.

#3 5 years ago

I do. I'll try that right now.

I would hook up a different monitor and video cable and see if things work. Assuming they work that way, then I'd try swapping the video cable to the existing monitor next.

Okay. Seems video output is fine. It's almost like the power supply for the monitor is the issue. Game boots up perfectly, switch the monitor on and I can see a flash of the OZ display and its okay. Then in a second it pulses, I can hear the computer fan rpm go down for a second and then the monitor and game crash.

Please go to Jerseyjackpinball.com and under support go to support portal and open a ticket and explain the issue so JJP can get you what you need.

LTG : )

I'll do just that Loyd. Everything works fine right up till you turn the monitor on. Then I see a quick game display on the monitor and down they go. Appreciate all your input everyone. Thanks again.

Put in a ticket with JJP , hopefully resolve this issue soon. It's either power supply for monitor, or the monitor itself. Seems the monitor gets power from plug marked coin door on the power supply board. Coin door power is working fine so maybe monitor ??? Damn, first real issue with it in almost two years. And I just got done saying my WOZ has never had issues. Serves me right to jinx myself like that. Anyone else ever have this issue?

This is what mine did when my monitor driver board went out.

Exactly what happened to me a month ago too. Quick response from JJP support to get me back up and running.

#11 5 years ago

Monitor driver board? Is that the board that supply's power to opto's and coin door down in the computer case?

#12 5 years ago

It's a rather small board located in the backbox. You have to remove the 4 or so screws that hold the monitor in place. JJP offered a quick replacement

#13 5 years ago

Thanks. Now no power at coin door and no boot. Think I might need two boards. Damn, this sucks!

Monitor power board, located in backbox. Mine did the exact same thing. You don't need 2 boards.

#15 5 years ago

Thanks for all your replys, much appreciated. Just got off the phone with Frank down at JJP. Sending me out a couple of new boards for replacement. He was extremely kind and took his time going over the issue Im experiencing. Could not have been easier getting support. Very impressed with JJP support and Frank, who was still awesome even though I interrupted his first cup of coffee this morning. Kudos JJP and thank you.

Hearing about support like this helps me feel better buying WOZ.

#17 5 years ago

Yeah I had an issue and called JJP and they have great tech support

I've had my WOZ almost two years now, they didn't hesitate to want to get my pin back up again. In sixty years I can't recall any company supporting a product as well as JJP has in my humble opinion. Fear not on your purchase, JJP crew will be standing behind you.

Ding dong. Present from JJP ! That was fast, thank you JJP crew. And I thought I was going to be bored today. No, just board install ! image.jpeg

#20 5 years ago

Good as new. Replaced monitor driver board, power supply board and new motherboard. Didn't think I needed a motherboard but JJP wanted me to change it out just in case.

Thanks Loyd and JJP support. Happy, happy, happy.

I had issues just like this after updating to the last code release and swapped out th power supply down by coinbox (mine was
one the afflicted one's for the swapout).
Now takes about 30 seconds to fully boot game with new code.
Then my son the other day turned it on and had a blank screen and asked what's up?
Turned off/back on and then all is well...
Is this that same monitor driver board? Or possibly something else.
Also a friend powered it on the other day and all the GI lights were out on the playfield.
He was able to start a game, then I came into the room and saw all the GI out as he was playing.
I had him turn off/turn back on and then it was fine...seemed to have started after the power supply swap and code
update which I did the same week.

Well I can tell you what I've learned, doubt your having a monitor driver board issue. If you did have the same issue as I did it wouldn't even let you boot the game unless you powered down the monitor first. That board is located behind your monitor in the back box. In two years I never had the lights go off on the playfield until I changed all the boards this week. I experienced it one time the day I changed the power supply and motherboard but it hasn't done it again, and it got played a ton yesterday. I don't think it software related as I had been running the 5.05 before the board swaps without issue. I'm not worrying about it since it only happened the one time. Boot times are much longer then they were so be patient when booting. I believe it's some sort of security routine on the software. Sometimes takes longer than 30 seconds so don't be to quick on shutting it off and rebooting. Hope that helps ya even a little bit.

If the playfield light issue is software related I'm sure Keith will fix that soon.

Yes, it has only happened the one time to me too (all the lights are off when starting a game).

Once in a while, I'll still get an upside down ERROR MSG in the Crystal Ball at power on and the only way to clear that message is to turn the game off and back on.

I got the same lights out once after the last update so I think it's in the software. Goes away with a reboot. If your monitor driver goes out the game won't boot up at all unless you cut the monitor off - you can still play the game but you'll have to keep score in your head.

5.05 brought additional boot time due to encryption requirements. Can't be brought down any further unfortunately. I've tuned it down as much as possible and it's hovers between 27-32 seconds.
