How do u reset unit to factory settingssc-ht730

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.

First thing is to check the wiring. a simple flipping of the positive and negative at the back of the theater box can fix this. I know they have the color coded wires and suppose to be plug and play but I see these reversed all the time right from the factory. If that does not work repost and I will follow up.

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.

replace fuse

If the sound is distorted and is effected by the volume control, the problem is in the "front end". This is not a common problem, but is significantly less expensive to fix than the output section. Try turning off any surround mode and run the unit in plain stereo. Does the distortion still occur? I suspect that it will not. Update this with that info and I should be able to list the probable parts that need to be replaced.

try turning the dvd off if this dosn't work than try rotating the tray , there maybe a cd jammed in the unit . If this is the case you will have to remove the cover and manually remove the cd.

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

this is easy       either bad cord or bad internal power supply.

For some reason this Panasonic unit does not offer surround sound in TV or VCR mode.  I guess their engineers decided it wasnt an important feature!!
