Why is the sound going in and out on my tv?

I have had that problem before. It wasnt my tv…it was my DirecTv receiver! Got a new one and problem solved.

are you sitting on the remote? it could be your cable connection.

I agree, it may not be the tv. It could be that your cables are loose, it could be that you’re receiving a bad signal from whatever it is you get your tv from. I’d check your cables, then call your provider before ditching the tv.

do you mean the sound actually goes off? or just fades and comes in loud for commercials? because the new cable boxes are set to deliberately make the commercials louder than the show you are watching.

Well, the sound of the speaker is created by vibrations of a diaphragm suspended in the speaker cone. These vibrations are made precise by alternating currents going through an electromagnet. What might be happening is (from either poor material use and construction or just old age) the coil in the electromagnet has been disturbed from too much vibration. This could cause fluctuating forces on the diaphragm, lowering and raising the volume output.

As far as fixing it, it would be possible to open up the TV and replace the speakers (NOT RECOMMENDED AS THE SHOCK FROM A CRT CAN EASILY KILL. PLEASE DON’T TRY AND FIX IT)

A more practical solution, without buying a new TV, would be to split the cable signal and send of the audio to a speaker system separate from your TV set.
