Donkey Kong Issue

[gyruss]

So my donkey kong stopped working after Eurocade...

It won't boot up right and shows the screen below, any idea what could be the problem?

[DarthNuno]

Well, the first symptom of a game who doesn't boot anymore is mostly a power supply issue. Did you already checked the voltage coming for your power supply?

[Etienne MacGyver]

since it was after moving the cabinet, perhaps it was a bumpy ride, so i would check all connectors and see what happens

if nothing changes, you know where to send your boardset i guess 

[gyruss]

no need for that because it was indeed a connector....

Glad it was just that

[gyruss]

Guess it wasn't a connectors because the problem is now back!  

So i i'll need to check the voltages, any idea where to start?

Edit: i have a spare working Nintendo power supply, i plugged that in but the problem is still there.....

Yeah, the problem is that you have numbers instead of that huge monkey.

Measure the +5V at the boardset.

Thanks, i believed Etienne showed me a while ago that there are also testpoints on the pcb itself (besides the connectors)?

How do i identify those? It's the 4 board version, so multiple small connectors.

Have you tried re-seating the eproms on the board itself?

Thanks guys, i'll try that this evening..

[ckong]

And when that doesn't work, then clean the edge connector(s), with a 'potloodgum'. Or do that first, because it probably is a good thing to do anyway. And is the edge connector making good contact?

By the way, I first thought it was a killscreen!    Or your High Score!

[gyruss]

Thanks for the advice, but there's no edge connector on this pcb, it's the 4 board version, so various small connectors.

The guys on klov also advised me to re-seat the roms and z80 chip on the cpu board, let's hope that will fix the problem..

[Robinholland]

this pcb set (4 pcb) don't have a edge connector
