  1. I have a Sony receiver that was in 'Protect' mode until I replaced a blown
    MP1620 & MN2488 that I believe were for the right front speaker. the
    reciever now works, however the right front speaker does not produce sound.
    Anyone know what else in this circut I should be looking for / replace? No
    visible damage can be seen on the board.

    If the 2 Trs you replaced were outputs then you've just got to test the
    junctions of all other ~Trs in that channel and look for OC resistors also-
    sometimes you can't see damage on them, they/re designed not to burn up now.
