Hi, I've just got my fm working on my 4230 by replacing the MPX ic, now I'm on to the next issue. The right rear channel is full of static. Sound and signal comes through, bit it's full of static. Interesting thing is the static continues through the headphones even after the unit is powered off. At the speaker out, when powered off the signal and stack disappears and it looks just like the left side on the scope. The static is present on the p700 amp board at pin j726 and j724, made me think it's the amplifier board, but the fact that it continues at the headphones after power is turned off makes me wonder if it's somewhere else. Any ideas? Thanks!
