The R7G looks like a winner. Checked out the first part of SWJSC-5xRAW, unfortunately it seem to me it's captured with the white level set a little high, haven't studied it too well yet but in certain parts the whites looked clipped to me?
Sad to hear the player is malfunctioning. I think you're doing the right choice of trying to fix it yourself. There used to be a few good service places in Stockholm and Göteborg I think but I'm not sure they exists any longer.
