No sound when i turn on my tv

Go into your settings and make sure that in the audio section that you have sound coming out the sound bar or tv or both... basically just make sure that your sound n speakers are turned on in the settings before you do anything else listed... sometimes the sound bar will change the settings when you first initially hook it up

Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. Refer the circuit diagram.

Found in menu setting of tv.are you using RCA or hdmi or optical output as these need to be set in mode setting on soundboard and tv menu settings.

check the speaker wires and terminals,if ok check the impedance of the speakers

Do you happen to have the model of the TV? My Samsung only has two digital optical outputs. If your'e plugging in JBLs, you may only have an analogue input which won't work.

Need to know some things:

Brand and model number of the set.

If you connected speakers from one unit to another did you disconnect speakers from the TV?

Speakers have different impedence's---(resistance) and if you hooked for example a 32 ohm to a set which uses 4 ohm speakers you may have little or NO sound.

Also if for some reason you had both speakers for both hooked up at the same time and turned the units on---may have destroyed the audio circuit.

Clarify a little what is hooked up and from where and how.

DVD MIKE,

do me a favor, if the set is still together, please remove the back, and find the convergence card... it is on the upper right hand side. Unplug the RED plastic plug ONLY. Now try to turn on the TV. If it turns on, but the picture looks completely out of convergence, then yo uneed to replace the 2 STK392-040 IC's and you will have to test all of the 3.9 ohm resistors on the board. You will usually find 1 or 2 bad. let me know what you find.

I WILL NOT BY AKIA TVS no more thay **** cant get parts

I had what may have been a similar problem and even talked to Westinghouse to see what I was doing wrong. Woman suggested there was a problem with the audio output port and suggested I exchange tv for another one. When the new one had the same problem, I discovered that to get audio out requires the volume to be turned way up on the tv (set speaker preference to external only if you don't want sound from tv speakers as well). If you have a digital optical connection on both the tv and the home theater, the sound output is independent from the tv setting and is easier to work with.
