Question about Audio Players & Recorders
I have a solution. I wrote to Panasonic requesting a Service Bulletin for this problem. They just directed me to were I could rent a manual. I did this. The voltages around Q5005 all looked OK. I believe this small transistor was just running to close to it maximum capabilities. I replaced it with a TIP31C and everything works fine. The transistor does not get hot and there are no more popping sounds. You will need a good technisian to perform this modification

Landon53, you are the BEST!
Had the exact same problem. I replaced the defect transistor with a TIP31C following your instructions: PROBLEM SOLVED!
Thanks again for the tip!

BTW... this all seems to be heat related, as the system sounds great otherwise, and since I took the cover off and left it open (to let air circulate) it has not popped once.... yet!

I replaced the transistor in my SA-HT40 like you said and so far so good. Just make sure you put it in the right way. I soldered it in backwards and got no sound so I had to take it apart again and flip it around.

you should check the outline ctrl..for a mic...it could produce a noise...if you have your speakers connected to pc...check the position of the plugs and the volumen of mic put in down...
