RCA Home Theater Receiver won't work

I purchased this unit, RV-9978 system about 1999. Receiver, sub-woofer, 5 surround sound speakers. The package is great, but not long ago, the receiver went dead for no apparent reason.....appears that it is not getting power. Any fuses or other items I can look for to get this back in operation? I always kept it clean from dust and it was never dropped so I am dumbfounded at this point!! Help Please!! Dennis

I wish to replace a subwoofer on a surround sound system

In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.

Replacing is simply plugging in the new and reconnecting the coax cable.

Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.

Hope this helps?

Which universal remote will operate every aspect of my dav-ex150 sony home theater system? Would like to adjust the settings for the speakers. As of now I only have sound coming from sub woofer and front...


On your receiver you should have a 'surround mode' and a 'display mode' which activate the surround speakers. If you are not in a 'mode' just the 'left', 'right' and 'sub' speakers will work. As for a remote, many of the newer receivers can be controlled via 'App' through a phone or tablet.
I hope this helps

The rear surround sound speakers are not working.the front ones are and the sub woofer works fine also. everything is connected properly but have no idea what to do to make them work.can you please help

Make sure that the media you are using has the surround if you are listening to the radio then the rear speaskers will not work as the signal is not transmitted in surround...if you put a dvd in that has the dolby digital signal encoded on it then the rears should work....the rears will only work when you have the receiver in the surround mode..make sure the receiver is in the right mode...also, you may have rear speaker volume settings in the setup menu that may need to be set up..go through the manual and see if there is a setting for the rear volume...most home theater sets have this feature and it allows you to set up the system for different size rooms

I have a Lifestyle 35 and want to replace head unit with a 5.1 receiver. The Bose subwoofer model LSPS uses a network type cable connector on the sub side and a male din plug on the head unit side of...

The entire 5.1 amplification system, in the Bose Lifestyle 35, is actually part of the Bose Acoustimass (subwoofer) module. The RJ-45 (network type) connector passes a low-voltage signal from the console to the Acoustimass module. If you were to hack the connection, and plug the speaker outputs of a 5.1 receiver to the RJ-45 socket on the Acoustimass module, you would blow the amplifier.

If you are really itching to replace the Bose Lifestyle 35 console with a regular 5.1 receiver, I strongly suggest you sell your Bose system, and purchase a Bose speaker system, such as the Acoustimass 10 Home Theater Speaker System, which is made for use with a standard 5.1 surround sound receiver.

Rear speakers not working

Your FM tuner will only generate sound from the front sepakers. CD's, Tape, and I guess mp3 player, as well, will only play through the front speakers.
I've included a link for the manual. The audio on this rig is pretty complex. read through the info, especially pages 11,12,13, and play with the audio controls.

no, u cant use the speakers with other normal DVD player because it wont have amplification for the speakers... u can use the sub to other dvd player because its inbuilt 120 watt woofer. ur dvd player is 5-disc player as wel as 120 X 2 and 80 X 3 watts amplifier (AV receiver ).... so just the JVC better sound thru the sub and speakers...

Problem w/ Panasonic SA-HT700 speakers

Try looking in the audio settings,it might be configured for stereo/mono or any number of surround sound settings e.g; 5:1, 7:1 In which case it might shut off the power to the circuit board inwhich the speakers are connected.If that fails .......Take it back!! Either the connection inside the speakers is faulty or the connections in the unit are faulty.
