I have received many RAM type errors on this board set. All rams on mpu replaced with 4116n ram. I still get the errant U48 or U17 error and Video Board Color RAM led configuration but the most consistent lights popping up is Communication RAM Addressing. On the sound board U2 microprocessor is blazing hot. The manual refers to the data processor being on the sound board. Any thoughts on what to check out or try? The screen just shows a wavy purple with lines through it. I can not get any signs of life out of it.
I don't have any extra parts for test purposes so I was hoping someone may have run into this and can help get me further along.
Thanks
