Title: killed my Klax
Post by: Solvalou on August 21, 2007, 03:22:09 pm

Hello,

I  killed my Klax PCB  :angry:
I made a mistake so I swap +5V and 12V, when i turn on the board now only a black screen appears, the same in self test mode. Can I do anything, or what component might be damaged? :(

Thanks for your help

I have nothing to offer other than condolences... I am addicted to KLAX.  What's your high score?

Thanks  :'(
I love Klax too, I think my high was about 137.000 with one coin.
When I cant repair it (i believe in), i try to get a new one

12 volts down the 5 volt line has the potential to damage lots of chips!  Any manner of logic, cpu, ram, eprom could all be damaged.   Or perhaps only one or two things could be damaged. 

Really there is no way to make any suggestions in a case like this.  Somebody knowledgeable in board repair would have to bench the board up and evaluate it.


Sorry mate....
