Television has audio but no video

Go to your menu.
go to sound or audio. look for any audio output options and disable them.

Does your audio go out while you watch antenna tv or when you watch a dvd/game?

Without knowing its model number and that of your television this answer has to be very general. Generally speaking you would connect a television to a surround sound system from the television's audio outputs to one of the surround sound system's auxiliary inputs. However most televisions do not have outputs. If your television fortunately has one, then you'd proceed to connect either the red and white RCA audio cable or the digital audio out one depending upon your television's capabilities. The RCA connection though just stereo sound is more reliable as the optical cable's performance can be iffy, and can have a lot of conditions that'll end up with it not working most of the time. The way I have mine set up is I connect all of my devices to the television with a video cable and then separately connect all of them to the surround sound system with an audio cable. Then to hear the sound from the various devices I press my function button on my remote or surround sound system to switch between FM radio, the set top box, and the dvd player.

Check to see if your audio source is set to SAP. This stands for secondary audio program. For example, some stations broadcast english and spanish. Some stations broadcast english and nothing. If you are on a channel that broadcasts english and nothing, and you are SAP setting, you will hear nothing.

Ur Tuner Signal board it dead,must replaced this board.

More than likley YEP! Contact an audio/video store that carries your brand of television to see if they can order a lamp for you. They are not cheap. Get a couple of quotes on price and availability if you can before you drop your $.

Hi jnks2005, We need to check your backlight, while tv is on and you have sound, take a flashlight and shine it on the screen, look very close and see if you can see a dark video image, If so you have a bad backlight inverter. You can try to unplug your tv for a couple of hours and let it reset but it is most likely the inverter. Let me know what you see and I can help you locate parts and instruct the replacement. Please rate this solution. lone99star

You most likely have the SAP mode activated. Look for a button on your remote or an item in the on-screen menus of your television called MTS or SAP. You want to set this to "Main" "Normal" or "Stereo" (or even "Mono") mode to hear the regular television sound.

If it is in SAP (Secondary Audio Program) mode, as I believe yours is, you may hear no sound or a different audio program. Often this is a translation to another language, such as Spanish, and other times (notably with PBS stations) it is an unrelated audio (often music) feed. On some stations there may be no sound at all with the audio mode set to SAP.

That is a good clue. Sounds like there is a bad connection in the audio circuitry. Does the audio output still work? The second thing I would do is visually inspect the solder joints in the area of the audio circuitry for anything suspicious.
