My technics sh-eh780 stereo seems to work but the sound is very dull in sound


Unless there's an issue with internal components of the amplifier or speakers, a common cause of this is reversed speaker polarity.

The wires between the + and - terminals of the speakers MUST connect to the same + and - terminals on the back of the stereo amplifier. The speaker wires that came with the stereo are color coded to help prevent mis-wiring. If you did not pay attention to this or used different wires for any reason, you need to ensure that the wires between the each of the speaker's 4 terminals connect to the correct group and + / - terminals on the amp.

See page 6 of the manual here: https://support.panasonic.co.nz/docstore/SC-EH780%20Operating%20Instructions.pdf

Make sure that the surround and center speakers are connected correctly, too.

Good luck!

Hi, All newer tv's have a menue that you can change settings to.
Audio and video both have parameters to. On your remote go to menue and look for audio settings and in that list should be surround

I need to make my speakers wires longer for my RCA surround sound


If your speaker have wires that are hooked directly to the speakers and there is no terminal, you will have to splice new wire onto the existing ones. Be carefull and use crimp connectors, available at Radio Shack, these connectors are best because they will keep the speaker wires from touching and damaging your unit.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Not good surround sound Is the bose lifestyle 5 support 5.1 surround sound?


The Bose Lifestyle 5 is not a 5.1 surround sound system. It is a 2.1 sound system, meaning it is stereo with a subwoofer/bass unit. Having two speakers that can be angled in different directions, the Bose Lifestyle 5 employs Bose direct/reflecting technology,providing greater audio presence. Still, it is definitely not a surround sound system.

Will not play , loud clicking noise. No lights nothing.


Ther clicking is probably coming from a relay and it is cycling because either the power supply itself or possibly an audio output power module has failed, the latter will overload the power supply so it tries to protect itself by interrupting either the AC or a DC voltage supplied by it.
This problem will likely require the hands-on of technical help.

Overload message in technics model SA- EX400P-K I have an older Technics system. It has worked great for years but now I get overload whenever I turn it on. Have changed speaker wires but no use. Any...


The overload message is the old version of "protect" mode. This means that a problem has been detected in the output amp section and that section is shutdown to prevent further damage. Your unit uses amp-pacs. One or more are bad. These are marked RSN3305P and cost about $66 each.
