Check the audio "out" settings on the TV
Modern LCD TVs, unlike older televisions, have additional settings for audio out, which could effect the volume being sent out the AV out jacks ... and sometimes a setting for sending the audio through the HDMI cable, which it sounds like you are not using ... so you don't want that enabled ...
If you can disable the volume control on the TV through the TV's settings that would be best.

It's also possible you have a bad cable, but if it works with another TV probably not that ...

Good luck!

Toshiba lcd tv 32" making noise by speaker


test this steps and fix it. God bless you

Line noise is feeding in from the AC line. Use an AC liner filter to block the line noise. RF (radio frequency) interference is being picked up by the power line or wiring. Remove sources of RF interference, such as fluorescent lighting or wireless devices not designed to work with audio/video equipment. Wires between the components are on top of one of the components; the transformers are causing RF interference. Be sure that wiring goes behind the components rather than on top or between components. If there is an equalizer in use, there could be a ground loop. Ground loops can be resolved by installing GLI's (ground loop isolators) on the cables connecting to the equalizer.

I want to connect microlab speaker to my sharp aquos 46" tv. please guide me how can I connect 6 plugs of the speaker to the rear of the tv? Thanks


Hello.
You can not connect any speaker to TV directly.
You TV have non-amplified output on the back "Audio out" that you connect using red and white RCA style cable into home theater system or some other audio amplifier. Amplifier itself should have outputs for speakers. Amplifier and speakers have to match. If you have just bare speaker/speakers I would recommend to get rid of it and purchase cheap home theater system that would definately solve your problem. They come with instructions and diagrams of how to connect it to TV.
Regards.
Russ.
