Sa-ht730 service manual - Panasonic SC-HT730 System

That's because it is not a stand alone system. In fact the power goes into the subwoofer box and then a cable feeds from that to the unit into the smaller of the sockets on the lower left of the picture.

PCB under DVD deck mulfunction, need replace working boards

Are you trying to reset the password for Ratings or re-initialize the unit to all factory defaults?

Page 27 shows one instance of INIT.

Re-initialize Setting

This returns all values in the Setup menus to the default settings.

≥Yes: The password screen is shown if "Ratings" (??? page 26) is set. Please enter the same password. After "INIT" on the display disappears, turn the unit off and on again.
≥No


Page 36 shows how to reset everything.

You have forgotten your ratings password. Reset all the settings to Factory Preset.

While stopped and "DVD/CD" is the source, press and hold ['Square Icon' button for STOP] on the main unit and [S10] on the remote control until "Initialized" disappears from the television. Turn the unit off and on again. All settings will return to the default values.

I have a SA-HT 690 system with a bad SB-WA342 sub. I can sell you my player or buy your sub.

Fixed Mine!!!!

My Home theatre started to do the same thing today and I manged to get it going again by reseting the ratings password and changing the batteries in my remote. Oddly enough, I have never set a ratings password so I suspect the batteries caused the issue. Seems to be back to normal. Instructions for the reset are in the manual. Here's a link to the online one at Panasonics website http://service.us.panasonic.com/OPERMANPDF/SAHT730.PDF
