Just picked up an LC 575 to use for my Mystic Color Classic upgrade. I was told it would power on but no image, so I thought maybe the analog board may be bad, which didn't concern me too much since I just want the logic board from it. However, when I got it home, I was pleasantly surprised to find that it booted just fine, including the original hard drive functioning (there were some great classic games on there). My guess is the seller didn't realize you needed hit the power button on a keyboard and was just hearing the CRT powering up when plugged in and the physical switch turned on.
There is one issue with it, and Im hoping it's not a logic board issue, but wanted to get an opinion from the group. So, the problem the computer has is that it appears as if the video signal is missing it's red component. I can see blues and greens, but no reds. It doesn't appear to be something with the RGB adjustments on the CRT, as I adjusted the levels on the back and I can make everything have a red tint.
I will probably follow @JDW 's example and try throwing it in the Color Classic to see if the problem exists there as well. If so, clearly it's an issue with the logic board. I still need to recap as well, but waiting for the caps to come in. I'll update this when I try it in the CC.
