I want to thank everyone in advance for any help! I also want to recognize that there are several very good posts pertaining to this issue and that I have read the pinwiki here:
Picked up this machine about a month ago and when I got it home it had switch matrix short message. The machine has a Rottendog Power Driver board in it when I picked it up. I tracked the issue down to the MPU/CPU board and ended up replacing that with a Rottendog as well. Plan is to send original board for repair out but the seller gave me some extra $$$ because of the issue so it paid for most of the rottendog board (cpu).
Everything was playing great until last night when in the middle of a game all flippers activated then kind of shut off and the game went in to a weird state. I promptly shut it off... and in turning back on was greeted with the Check Fuse f115 f114 message.
A lot of the posts point directly to issues either on the Driver Board or the CPU - both which have been replaced with Rottendog board in my machines and is why I am posting this. Any insight of issues with these boards? Both of them are new within the past couple months - the cpu is less than 3 weeks old.
What I know:
1. New Rottendog CPU and Driver Board Installed
2. Fuses 114 and 115 are not blown and test fine
3. LED6 is lit tests fine
4. LED1 is NOT lit - voltage shows 0 vdc instead of 12v
5. LED 8 tests fine
Seems the start of my research points to checking the diodes as well as C2 and 7812.
My hesitation/question is - where do I go since both of the boards are new? Continue down the same testing path as documented? Are there common failure components for rottendog boards? I read there were some bad ones out there but couldn't find details? Thanks
