Having some odd issues with a rottendog driver board in my Lord of the Rings. During the game (about two thirds of the way through), flippers die, the ball will drain and the game continues. It will show the next ball and the display and sounds keep going, but no ball gets kicked out, flippers remain dead, and lights stay on. I just shut it down and restarted it. No issues, game starts having no issues. I went into the test menu, and checked tech alerts, it showed all ok.

Seen this exact same problem on a couple of other threads but no real solution other than getting another stern driver rather than a Rottendog.

I attached a picture of the led that goes out on the board.

Is there a fix? I don't simply want to toss out a rottendog board that I spent good money on. Are there components that can be upgraded or changed to fix this board?

Attached is a pic of the led that goes out when coils die.

Any help is much appreciated.

Thank you!

Have you contacted rottendog ? One of my rottendogs was burned up by my voltage regulator and I sent it in and they repaired it no charge. I don't know how their customer service is now but I was impressed when they did that for me because it wasn't the fault of the rottendog board. They also helped me troubleshoot a couple over the phone before too.

Try jumpering pin 3 to pin 4 on U210.

That will be the top two pins on the left side of U210 as it sits in the game...

I feel like I read this exact same issue in another thread a week or so ago. Definitely check with the manufacturer was a heavy suggestion there.

Rob,
I am not seeing u218. Just u18. The only 8 leg chip I see is U210, shown in my pic

Can't THANK you enough Rob!
Thanks to everyone that respoded

Check my link. U210 is the correct ic to put the jumper on.

Sorry. Updated my post to reflect correct IC designation.

I am having this same issue on my Apollo 13. Is the fix the same?
Rottendog board. Exact same scenario as my first post 8 months ago.

Thank you

I'm glad there is a jumper solution but for the uneducated what exactly is going on that a jumper is needed?

Pin 3 is the tolerance selection for the CPU monitor (U210).
It must be tied to either +5V (reset's CPU if voltage drops below 4.5V) or ground (reset's CPU if voltage drops below 4.75V). It should never be left floating... which is what this board does.
The Sega PDF linked to by stangbat covers this pin 3 a bit. They had the tolerance set too high (grounded) which caused too many resets. So they instruct the user to clip that ground which forces the pin to float (neither grounded nor pulled to +5V). An IC signal *usually* floats high when unconnected but this cannot be guaranteed. What the Sega PDF should have then done to make the fix proper is add a jumper wire from pin 8 to pin 3.

Note that the jumper shown in photo above ties pin 3 to ground. This forces the CPU to reset if the voltage drops below 4.75V. If the CPU continues to reset occasionally with this fix then the jumper wire should be removed and tied between pin 3 and 8 instead (pin 8 is the signal with the thicker trace on bottom of board). This would force the CPU to reset if the voltage drops below 4.5V.
