My Robotron (that I got for $30!) had been working just fine until recently. It stays on for about 10 minutes or so then the game goes out. If I let it sit for a few hours it starts and eventually fails again. One other detail is that the game wont work at all if the coin door power is connected.
Monitor and marquee lamp still have power. The +5vdc LED (LED 1) on the power supply board goes out. I need to re-check the voltage coming out to the board but it looked like the -5 and +5's were all fine. The +12 seemed to be really low, closer to 5. I checked the fuses and they seemed to be fine. Im going to check the power again after a couple hours to see what it looks like before it starts failing.
Any suggestions? What are some good ways to test the power supply out? Would this be a candidate for Bob Roberts repair kit?
Thanks for any help.
