I'm thinking its a chip , not sure which one , display is weak , with slight "ghoasting" ... Gal chip..?

Seems like the little Dallas chip under the battery is ok...

5 volt seems great everywhere on the boards..

U-11?

It's always a slightly educated guess for me , problem with this game is , no one around here will work on it ..

Thanks for any CBW input

Well, I'm glad to hear that it's not the gal chip..

I wil try your steps mid day here . Thank! The Dmd might be burnt , it has a lot of dark spots where the Display dots are .. Can I use a williams display in the game for testimg ..,

Here is a pic of the "burnt looking" display

Thanks viper ...

I tried a working DMD out of a judge dreed and it never worked . I have a data east DMD , looks like it would plug in , I just don't want to blow another board ..

Reset didn't work ,

when turning on and off you have to do it fast. A quick on and off or it won't boot ,

Everything works great other than that ..

Thanks everyone

Thanks neo, that's one thing I'm well aware of.. I've gotten so I never unplug, work, change bulbs , adjust switches or anything like that with the power on ...

Ha , yeah , I see exactly where this is going.... Might just have to send the board in... I've fixed a few things by changing chips and what not , shit the Dmd driver I fixed actually worked , I was just too scared to plug it in, without getting proper voltages.

Thanks for your advice viperrwk, you have been quite helpful ....

Interesting that it's very specific the way you can get his game to boot.
You almost have to wait for a split second as the caps are powering down , to turn back on

A 1/2 second later it won't boot

Good guys that work on gottlieb? Maybe k's arcade?

I've been playing Cur ball wizard quite a bit , and I must say , I really like the game , shit , I'm been humming the theme song for 2 days at work..

You guys are wildly smart , and I appreciate that.. Thanks !!

Will will try the "shotgun approach ". I should buy a manual to get the values for these parts ...

Watchdog circut? Sounds pretty fricken cool .. What the hell does it do ?

Thanks tj
