looks like failure in data-known ICs TDA7372 or M51132, not CT1975 For 2 known good CT1975 , DC V, no load pins 1 to 11
0.8(ch2 in), *, 0,8,0.8(ch1 in),0(gnd),8,8(op1),16 (sup), 8(op2),12.3
- is 2 V on one used as 2 separate channels and varies (no pcb connection to that pin) 0 to 0.6V floating presumably, on one probably set in bridge configuration driving the sub-woofer.
Anyone have a more complete pinout/full data, JIC ?
