Just installed my new JROK board for my Defender cab, all went well, loving the JROK and playing Defender and Stargate 
But then I thought before retiring the original boards which had been working perfectly, I would recheck the scores and settings.
Replugged the leads, and found no video output, monitor came on but nothing displaying.
Still had sound for power up, and four leds on rom board lit once at power on.
Then I checked around and found the sound stopped working all of a sudden.
Bugger...................yeah the jrok is better than ever, but I want to know that the original boards work
I noticed I left the 3 pin power plug connected to the original ROM while playing jrok, could that have caused a problem????
