Does anyone know or recommend a trustworthy source for board repair these days? I have a Carnival I cannot get going, and would like it looked at. Just gives a red screen. I have it powered by a switcher, and have good, solid voltages at all the test points, RAM/ROM, and traces. I know this will run with the +12v running to the 3VAC pin, and I have the -5v going to the -12v pins as we do with the Williams boards. If it is a good board it should be doing something I would think. Any suggestions would be helpful. Thanks.
