Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, which diode was replaced please? ...and which is the "...fusible link..."?
Appreciate the additional information.
Please post back with clear picture(s) of the circuit board with the part label readable. Click HERE.
And yes, it would appear that instead of a fuse, a jumper wire is in place.
The thermistor TH1 is usually located almost between the 2 large capacitors C2 & C6 and the bridge diode BR1.
From the schematics/Service Manual, the zener diode ZD3 should be 18V / 0.5W.
Next test would be for carefully testing for the presence/consistency of voltage between the 2 outermost pins of the bridge diode BR1.
Carefully follow/trace/re-measure this voltage at:
Similarly, carefully measure the voltages at:
Incidentally, were you able to confirm/determine the absence/resistance of TH1?
Any update on the Boston MCS 95 subwoofer?
I understand and appreciate the post back; no prob when able.
