There are two things that can cause this, 1 there is a muting transistor on the bottom of the PCB that is a surface mount transistor that goes short. this is the channel mute transistor. when you change channels it is designed to mute the static between channel changes. if it shorts then it mutes. 2 the EE-PROM is defective and needs to be replaced. i'de go with the transistor first. if you are unequipped to do this repair have a tech do it.

No sound is coming out of my tv


Check whether mute function is on or not. Enter its sound menu and check it. If it is not off there, the fault is with its audio processor section, mute section, or audio output section. To make it confirm, your set need a through checkup. Contact any experienced service technician.

How do I turn off the tv speakers so that I may use surround sound?


Depending on the model TV, there may be a switch on the back to turn the speakers off, or there may a choice on the audio on-screen menu to turn them off. Not all sets allow you to turn the speakers off, but you can always mute the sound, although this sometimes leaves the word "MUTE" on the screen to remind you. You can also just turn the volume all the way down on the TV. If you're using the AV inputs on the TV with a device like a DVD player, another option is to connect the video only to the TV, and feed the audio to the amplifier providing surround sound. Then the TV speakers won't be used at all.

Sound trouble


If you have a cell phone or wireless internet this may cause interference. If you have any of these close them out and see if it still does the sound.

GE 35GT740 35" NO SOUND


Did you try turning up the volume on the remote or front panel?

Also, try unplugging the TV from the AC outlet for about 15 seconds to make the TV do a re-set.

Beyond this, there is most likely a failure and the set will require service.

Sound level unstable


Hi there!
You may have a button stuck either on the remote or on the TV itself. If this does not solve the problem, you may have to refer to a service technician. The IF Amp or the sound stage may be at fault. Good Luck, Regards, JUS004
