Hello I own two of these 321 models but on one of them, the sound is too low. On level 15 you almost hear nothing. Does anyone have an idea?

Maybe the mute transistors or a missing voltage at the pre amp

Hi bro, I have a device like yours, out of nowhere it started making interference noise when it is set to Dolby 5.1. But when it is in 2.0 it doesn't. Do you know what it could be?

Try to move the wire connected to the bass speaker sir, maybe there is a broken wire or cut off

hello, good afternoon. my bose321 does not hear the sound at all. I replaced the IRFZ44N but it still doesn't sound. Could it be a problem with the TDA7396?

How much voltage did you measure on the big capacitor? if its high it won't really work, it shouldn't exeed 18 or 20 volts

@@glenntips Thank you very much for answering! I made the measurement on the capacitor and I have 23vcc with everything connected. AC voltage is 120v. What else could be happening?

@@glenntips The problem with the R10 was mine, that I made the wrong banding and it was 1 k. The one I was putting on it was 0.1 k. I did the measurement that you recommended in the IRFZ44N mosfet and detected that it had continuity in the 3 pins. I took it out and measured it outside and it also gives me continuity. I put a new one, I check it before connecting it but after connecting it to the source it burns again.
