i have no volume on my t.v and every channel stays the same any techno advice or help is needed thanks?

Answer 1

It could be a blown speaker. If you are using a stand alone TV then you can take it apart, find the speaker and check the current across the speaker. Be careful the speaker is made of black paper and easy to break, which will ruin it. Radio Shack sells speakers; you don’t want an audio speaker, but a speaker component. To replace the speaker you will need to wire and solder it into place.

If you are using a device like a: VCR, TVO, a DVD player, a satellite box, or some cable boxes then you should be using RCA Jacks and Wires, or RF wires. Unplug these wires and plug them back in and see if the system works. RF wires take a broadcast signal into the device. The device has to convert it into a video signal. If you connect a device to the TV then you again have to convert the signal: video to broadcast, broadcast video. RCA jacks and wires are superior because they keep the signal as a video signal. Also make sure to keep the device OUT jack going to IN jack on the TV.

A RCA Jack on a device is round with a metal coating, on the outside (the top of the line jacks are gold plated). It has a round inner insulation layer that is plastic and colored either red, white or yellow. Then there is a round hole in the middle. The wires end in plugs, in the center, that has a round metal tube, which ends in a rounded tip. It enters the core of the plug. The outside of the plug has 3-4 curved metal flanges that fit around the outer metal ring on the jack. There is an air gap between the outer flanges, and the inner core. RCA wires send a direct signal to the TV, two audio signals, and one video signal (usually colored yellow). The red insulated plug goes into the right and the white goes into the left. You can change that if you want just make sure that red goes to red, and white goes to white. Unplug the wires and lick the inner metal core, salty water makes an excellent conductor. Then plug the wires back into the jacks on the device, make sure they are in tight. Do the same to the TV and test the system. Change around the jacks and see if there is a difference. Set your TV volume to high to make sure you hear the signal.

If you have RCA jacks, as do most stereos, then you can bypass the TV speaker and connect audio speakers directly to the device output. These are the stand alone speakers that you can buy are Radio Shack or any audio store. However you will need an amplifier to connect the audio speakers to. The audio speakers are connected with speaker wire, which is a pair of plain wires stuck together. You have to cut the two wires apart for about 1”-2” then strip off the end of the two wires. You can plug these wired into the back of the audio speaker. The audio speaker has a red and white push down button. When you push the button down you open the clamp to hold the wire, when you release the wire, it will stay in tight. You can connect up to 6 speakers to an amplifier, which will give you 5.1 surround sound. You will need 2-4 standard speakers, a center speaker, and a woofer. The center speaker and the woofer (put the woofer down low) are put near the TV while the other speakers are put in the corners of the rooms. Ask the salesman how you should position them, and why.

If you use a signal wire connector between the device and the TV then you are taking a video signal, changing into a broadcast signal, sending that signal to a TV which takes the broadcast signal and converts it to a video signal. That's why so many people use RCA jacks; they get a purer signal. You are using an RF Wire. The RF Wire is black with and insulated exterior, and a thin wire in the middle. The jack on the device has a metal screw exterior with a white plastic insulator and a thin hole to accept the thin wire in the RF Wire. Make sure that this wire isn’t bent out of place, and is long enough to stick into the jack; check both ends. Some cable boxes have a RF wire from the wall to the box, and then another from the box to the device or the TV, check these wires.

Answer 2

try to plug your tv in a different outlit if it still dont work ether have loose wire or your speakers got old and blown themselfs out cause my tv did that couple time if they get old i guess they do that.

Answer 3

Check your mute button.
Next check your menu for setup/ audio, and see if you need to turn on you speakers.
