Default Problem with HCA-2200II

Hello! I have a problem with my 2200II. The left channel started to 'spark' like it lost the audio feed, when I were playing music. I opened the amp, and I found that the Diodes Z602 to Z606 was a bit burned. I replaced these, but the problem is still there. I don't know the reason why they were burned.

And I'm looking for a component list, or the schematics for HCA-2200II??

Any thoughts anyone?

And there is a couple of blue resistors that says -047K 250 Full Med. They look a bit damaged. But I don't know what kind they are....
