Unit blew the internal fuse. SONY SA-WMS367 SUB-WOOFER

Based on you information, if you disconnected magnatron and unit ran with no fuse problem, I would suspect magnatron. You should consider the age of unit it, may be be a better alternative to replace it.

The SA-HT700 is the main unit for the SC-HT700 DVD Home Theater system. For this system, the sub-woofer (SA-WA340) has the AC power connection. The sub-woofer is connected to the main unit by a "System cable". The power cord and system cable are shown in the manual. You'll need the sub-woofer if you don't have one. Amazon has a used sub-woofer listed here: https://www.amazon.com/Panasonic-SB-WA340-Powered-Subwoofer-SA-HT700/dp/B076HB8HQP . However, I don't know the third-party vendor.

A replacement power cable for some regions is available at Amazon here: https://www.amazon.com/Polarized-Panasonic-SA-HT700-SA-HT80-SCHT1500/dp/B00VFHP9US . I found the system cable here: https://www.amazon.com/Matsushita-Panasonic-K1HA25HA0001-CABLE-65/dp/B001DPHPCC . See the manual for the correct part numbers: ftp://ftp.panasonic.com/hometheater/om/sc-ht900_en_om.pdf . The accessories that come in the box are shown on page 3.

I hope this helps.

Link for the service manual: http://elektrotanya.com/pioneer_vsx-305_405.pdf/download.html On page 50 of the manual (36 of the pdf) it says for the "Sub woofer pre-out jack (Not available on the VSX-305 model) If you want to boost the low frequencies, connect to a subwoofer power amplifier" Your model will not drive a sub-woofer with out another amp. His sub may be a powered sub?

your speakers were sitting to close to sub woofer and what happen was when puttind to batteries together what happens they move away from each other you blew your sub woofer the only thing to do now is replace subwoofer.

It is based on your sub-woofer type..whether powered or passive sub woofer..
Assume that you have powered one..RCA sub woofer jack is the best to feed it ..you should use RCA sub woofer output on your receiver as well..good luck

The switching power supply transistors have shorted out. Other parts may be gone also. A difficult fix. Too bad, it's a great sub.

Make sure subwoofer button is pressed and registers that sub is set on, the check dB level adustment for sub channel with remote.

first you have to check any short circut , that may be inside of sub woofer unit .
find and sove any short circutry and then only replace the fuse with same rating.
and before you switch on it once again recheck any meterial shored with electronics pcb.

THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.

Hello Levelle,

Fuses are designed to be protection devices, that is, to destroy themselves in order to protect an electronic circuit. Now, when brand new replacement fuses blow, it could mean two things: 1.- The replacement fuses are below the specified rating (you can find the rating by reading around the end metal caps of the original fuse), or
2.- The internal circuitry of the unit is damaged and is causing the fuses to blow immediately.

There is not much you can do yourself, unless you are technically inclined and know how to test the unit for internal damage. If you are not technically inclined, your best bet is to have the unit inspected to asses the damages and the cost of repair if you elect to do so.
Hope this helps. Let me know if we can be of further assistance.
