Question about Marantz SR-5000
Most likley, if I'm right, you have heard some staitcy, crackly noises, accompanied with this failure. If so, the problem is without a doubt on the D.S.P. board, witch is the one with the optical jacks on it, The culprits would then be I.C. 719 & I.C. 720. This is a common problem with this model, and the sr6200 & 5200 as well. A low tech method to confirm this is to touch IC 720 (the smaller one) while it's on. If you can keep your fingertip on it for at least ten seconds, it's ok, and the problem is elsewhere. If not, (IT WILL BE VERY HOT) the the board must be removed (27 screws from left to right) and replace BOTH IC719 & IC720.
