I know this is an older thread, but I have to report that I also have issues with a FLP023 Rottendog DE flipper board. It is burning through fuses for the right flipper, and in fact seems to get "stuck" sending a continuous 50v to the coil, causing it to heat up like crazy and burn up the paper sleeve. I replaced it with an original DE board, checked all voltages with a DMM, and all is good. Will try to get a refund for the RD...

Hi! I most certainly did adjust the dip switches for TFTC, and checked it twice. For some reason, the board must have sent a continuous 50 volts to the coil, effectively frying it. The 50v cycle is handled by a timer on the board, so it seems that this timer did not "work." I reverted to an original board, and all is good. I am trying to return the RD board. As a backup, I just ordered an aftermarket board from a German company PinLED, and I will try it out. I love DE games, and I worry that parts will get too scarce, so I always want a backup...

The seller agreed to take a return on the Rottendog board, so all good there. I am receiving the PinLED board in a couple of days, so I will give it a try. I agree that I probably don't need a backup, but couldn't hurt... Might be able to help somebody else out in the future.
