Hi, I’m new to this forum, so I hope I posted in the right spot. I was a Tales From the Crypt Pinball machine. When you turn it on, it lights up but no display and nothing happens. I had a repairman come in. He replaced the motherboard and a rectifier in the power supply. It started working. But, now stopped agai doing exactly the same thing $700 later. This time, if I leave it on for a few minutes, it may start working. Sometimes it works and sometimes not. Can anyone help? It seems like it was neither the motherboard nor the rectifier.
