I have a ModelVK-42F240S that has no audio. Anything to try to cure the problem? Westinghouse TV

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, 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. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

Check the speaker/s first. 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.

Sounds to me like you are trying to use a composite hookup or a generic HDMI cable. If you get the official Microsoft HDMI connector it also includes phono audio outputs and an optical audio out for 5.1 surround,

Normally it depends on what connection you are using to output a signal, all of the inputs on this unit are in one single board. What you need to do is to replace the main board because it sounds like your inputs migh have gone out. To check price and availability on the main board you can contact Westinghouse parts department at [email protected], please make sure to include the model # along with serial # and TW# all loacted on the back of the unit. Hope this information was helpfull.

Hello, this is an interesting one since on this unit what ever the device you are using will determin the type of audio you output on the speakers. I would love to troubleshoot a bit more with you live, can you please send me an email of how to get in contact with you to [email protected].

I had a similar problem with a Mac Mini.  The problem was caused by a mix-matched resolution (the Mac tries to use 75Hz refresh rate, TV expects 60Hz).  The best solution I found was to remote into the Mac (I used LogMeIn.com) and change the resolution on the Mac from a remote computer until the image appears on screen.
Process: 1) Connect Mac to a normal monitor and install the LogMeIn server (or other VNC type application) 2) Connect the Mac to the TV 3) Connect to LogMeIn from another computer (preferrably one where you can see the TV) 4) Go to Applications / System Preferences / Display 5) Change the resolution to your TVs native resolution, and change the refresh rate to 60Hz

This is an inherant problem with TV and according to dealer there is no cure. My dealer made a deal on another TV for me. Tough luck

I just tried a Sony code for my Westinghouse tv after reading other sites, and it worked. The code that worked for me was 10000
