Does it make any strange noise with no RCA cables plugged into it?

If not, you need to check the shield grounds on your head unit.

    Damage to the head unit can cause the amplifier to do strange things. We need to know if the head unit is working properly before you can do more troubleshooting.

Toshiba VC-L2B Remote Control Sound volume bar is moving up and down, but there is no sound out of speaker.


Check to make sure the wiring between the sound bar and your audio source is hooked up correctly. Check the source to see if it has it's own volume control. Many TVs require external speakers to be enabled in the "audio" section of your TV's "Settings" menu.

Hooked up the amp, lights up, fans kick on and run fine, speakers hooked up proper, no sound? hooked up speakers to another amp and they work fine. Fuses are all good too. Thoughts?


could be bad rca cables or no output from the radio rca outputs. the sub control may be turned off on the radio (ive seen that alot at my work). if all that is fine, the amplifier may be bad. the rca cables may be plugged into the "out" section of the amp. gotta look at all the small obvious things first. good luck.

Need home theater hooked to TV with built in DVD


This is the easiest way 2 explain it. Hook up on the home theater should be labeled in and out. same as on the tv. The TV might no have that feature as the DVD is built in. You might just have an option for sound from the TV/DVD to the home theater. Again OUT from TV IN to receiver. Same with any other device set up.

No sound at all


The jumpers are there to connect the preamp section to the power amp section and are required for the receiver to opperate properly. Make sure the receiver is set to the proper input, in this case: CD. If there are A/B speaker connections, be sure the receiver is set to match the connectors you're using. If there is still no sound, profesional service will be required.

Noise on rear speakers


yeah i used to have this problem too forever, untill i was playing around with them and figured out the problem. on your remote there is a shift function, while holding shift you need to turn up rear speakers also on the remote, i think its near 1 or 2 or somthing. just look for rear level, turn that up and make sure you have the proper audio setting and that should fix it.
