Squeak I have a RCA TV 27'. When the TV is on and the TV is not muted, there is a squeak that comes from the back of the TV. It sounds like there is a cricket in the back of the TV. It is not coming from the speakers. When I move the cable wire around it will stop for a few seconds and then start again. Also, when we walk around the apartment you can hear it make noises based on us stomping on the floor. Please help!!

The high pitch squeal you hear is usually caused by a coil vibrating, normally in the horizontal circuit. I've also seen the ferrite bead on the horizontal output transistor do this, but, it is rare. I normally will repair this by finding the coil and "tightening" it. To tighten a coil, technicians use different chemicals, such as, a hot glue gun, rubber silicone or even finger nail polish. I will find the coil that screams by starting with the usual suspects and using a wooden dowel, barely touch the coil and if the pitch of the noise changes, then, thats the coil that needs repaired. If you do not know your way around the inside of a television, I never recommend you do so, since, this procedure must be done with the set turned on and you poke your hands around the inside of the set by the high voltage circuit. Hope this helps your decision.

What do i do if the picture on my tv is good but i don't have sound?

Hello
Check first whether mute function is ON or not. If it is ON, make it OFF. If mute is OFF and still there is no sound from your TV, connect it to any other audio output sources, like an external amplifier or so, by connecting TVs external audio out sockets at its back and see whether there is sound output form amp. If not, make sure that the audio processing section circuits inside your tV is fulty. If there is soudn from amp, and not from the TV, check the speaker of the TV. If it is ok, then audio output section circuit of your TV is faulty, and need repair. OK.

No sound

I know this sounds stupid but when was the last time you replaced the batteries in the remote? Can you use the TV volume button to change the volume up out of mute?
