I'm in the same boat. I picked up a Mac TV that's dead as a doornail. I was told in another post here that the power LED should at least illuminate when the logicboard is not inserted, if it doesn't then the analog board is dead. With that advice, I picked up another analog board on eBay. I popped it in and still, nothing.
I then recently picked up an LC 575 of unkown condition for $5. For so cheap, I figured I'd drive the 30 minutes and pick it up. I was hoping that at minimum, I'd be able to pull the analog board out of that and try it. But that machine doesn't power on either. It's driving me nuts. 3 dead analog boards?
I've tried multiple power cords and keyboards to rule those out as culprits. When I plug the power cord in and turn on the mains from the back, I can hear a slight chirp come from the tube. So something is getting power. It just doesn't turn on. The logic board does look like the caps are all leaky, becasue there's white streaks all over the board. But again, the LED on the front should still illuminate when plugged in without the logicboard attatched, but it doesn't. I may have 3 dead analog boards and 2 dead logicboards. But it seems unlikly. I guess I'm just missing something.
