Trying to restore a Zaccaria Crazy Kong Cabinet

[level42]

Well, I think you put it in an area where it won't be touched much so not too bad there.

My experience is that it's extremely weak. Slightest contact and it will go off...

[Etienne MacGyver]

right so best is to go for a flat mounting plate then,i thought al joysticks had the same mounting plate
so i need to be careful then wat i wil order.
cos i dont wana make bigger holes and stuff in me control panel if it possible.

i think im going for a joystick with a ball on top.

As long as you can take the stick out, or screw the ball off youre fine, remember that the ball will not go through the plexi

right i didnt know that,i only did the coindoor bezel and the marque and bezel plate.
oke so next time i wil not use any gamma paint ,normaly i always use motip,but they didnt got motip black at gamma.

As long as you can take the stick out, or screw the ball off youre fine, remember that the ball will not go through the plexi 

good to point that out,so i need to watch that too

You were right level42 even after a long dry,things come loose verry quick
Thats some real mess they sell there and it was the same price as motip black

Lol,no i like the shiny stuf 

reminds me of polishing and polishing, and after that ... polishing 

ay it isnt i nice job,but if your done and see the diffrence ,your glad you did it

Finaly i got the new pcb



Right lets see if evrything is oke
After starting it up for the first time,picture didnt look good
So time to adjust the monitor,after 10 min i stil got a strange white line at the top of me screen,and
the bottom of the screen was dark.
It didnt get away by adjusting the monitor.
So i just get some movement on the conector thats on the pcb,and whala

 









mario got the right colors again monkey looks good

so far evrythings seems to look oke.
Now its time to play it for a few hours to test it good 
After that i stil need to fine tune the monitor a bit,i saw that there were 2 brightnes  Buttons.
so need to get a closer look at the hantarex manual
But for now its testing time

after 4 hours testing the  board has a problem again
i was playing and the screen jumpt to this




 
frustrating

[Etienne MacGyver]

I am not an expert, but it looks like a ram error

Do you have it running on the original powersupply ?
If yes, check the 5 Volt line, and is the fan working ?
Those original powersupply's tend to get hot of the fan is not working, so firts let it cool down and check again

[solidsnake]

Do you have it running on the original powersupply ?

nop that wil be the last thing i gona restore,it is runing on a modern power suply for now
i have 5v al around the board.
i already put the machine out for 2 hours start it up again and it stays the same

is there a way to test ram or do you need special equipment for that

[Etienne MacGyver]

Thats as far as my knowlegde goes 

I have 2 boards with issues at RobinHolland for repair

Looks splendid. What did you use do clean the metal and oxidation?

[solidsnake]

What did you use do clean the metal and oxidation?

First i took sandpaper 180  on a sanding machine just as long that the spots-rust or oxidation is gone.
Then i sanded the parts with sandpaper 400,so the deep scratches go away.
After that i used a chrome & laque polish
and then its shinning like new again 

[level42]

Great work on the metal !

About the board: Carefully remove all socketed chips (one at a time), and firmly re-insert them. Then see what happens.

[Etienne MacGyver]

Yeah, looks like i need to revisit the inside of my door again with sandpaper...
