I got cable and now i cannot get audio on my t.v. The picture is fine just no sound. I hit menu twice and got to volume control and it is set to variable. The cable guy says there is something wrong with my t.v. but i don't believe that as it has been working just fine. Please let me know if there are other things i can try that I have not done. Thank you.

Hi Geoff, I hope I can help you with this. If you are using an accessory device (DVD, DVR) check cables to see that they are secure and if device has audio out option that it is set correctly. Also check to see that Video and Audio cables are connected to matching inputs on your set.
If you are using DVI to HDMI you will need to use a separate digital audio cable. DVI cables do not carry audio signal. After attaching the audio cable if you still do not hear sound you may need to set Digital Audio In. To do so:

1. Press Menu Button on remote.
2. Press the cursor ring down to highlight SETUP.
3. Press the cursor ring left to enter SETUP menu.
4. Press the cursor ring down to highlight SOURCE.
5. Press the cursor ring left to enter SOURCE menu.
6. Press the cursor ring down to highlight DIGITAL AUDIO IN.
7. Press the cursor ring down to select the source you want to associate Digital Audio with. HDMI 1 or HDMI 2 in this case. You might need a software update also.
   The latest software solves the issues below:
   
   1. TV (Plasma 42" and 50") will not turn ON/shut off itself and Red LED blinks 4- times. Recover if main switch on/off.
   2. 37" LCD full white screen appear when upgrade software.
   3. Some channels not available after turn ON.
   4. Delta volume changes, not remembered.
   5. Preferred channel changes, not remembered.
   6. Green or yellow static (sometime snowy) on HDMI picture.
   7. Picture and sound loss for 5 to 10 sec (green LED is still ON) and back to normal.
   8. Audio loss in all inputs and can be recovered when main switch ON and OFF.
   9. TV set turn ON by itself/ green LED light up and goes off when set is ON.
   10. Intermittent audio loss in NTSC RF channel.
   11. Crack sound with high input signal.
   12. Include the possibility to download the rating table (RRT5 capability) for digital programs.
   13. No video/ no picture with sound.
   14. Intermittent On-Screen Menu pop up by itself and can be removed by pressing the 'MENU' button.
   15. Channel information display too long.
   16. Improvement on scramble channel.
   How to check the current software version on my TV set?
   
   1. Press 'MENU' button on remote control to display the on-screen menu.
   2. Select TV MENU and press the cursor right.
   3. Select INSTALLATION and press the cursor right.
   4. Select SOFTWARE UPGRADE and press cursor right.
   5. Select CURRENT SOFTWARE INFO to display the current software version on your TV set.
   6. If the TV software version is lower than the version posted on the website means your TV set needs to be upgraded.
   7. Follow the instruction in the user manual or Firmware Upgrade Readme file on how to upgrade your software.
   Where can I find the latest software for my TV set?
   The Firmware Upgrade Software and Readme File documents can be found on the Philips support website. Refer to the SOFTWARE section.
   

Make sure that your audio cables are plugged in properly to the correct ports if your audio is distorted or noisy. Every cable should be inserted completely. If you still encounter bad audio, replace the cable and then attempt to use a different device with the old cable. This will help you pinpoint the source of the bad audio problem.

2

Use the "Volume up" button on the remote or TV buttons panel to turn up the TV audio volume if the volume is quiet. If the volume is still quiet, check to see if your audio source device has volume settings. If it does, turn the up the volume on your device (see your device documentation if you need help with this).

3

Press the "Mute" button on your remote control to disable the mute function if you can't hear any audio. Once disabled, press and hold the "Volume up" button on your remote control to turn up the volume. If there is still no audio, press the "Menu" button on your remote control, select the "Audio" menu, and ensure that the "TV Speakers" are set to "On." If you are still not having any luck and are using the built-in TV tuner, open "MTS Audio" inside the "Tuner" menu and make sure it is set to "Stereo/English." If there is still no audio, verify that all your audio cables (including the antenna cable if you are using one) are plugged securely into the proper ports on your TV and audio source device (if applicable). If you are using an antenna, reposition it to a clear, open area; preferably near a window. If your audio source device has audio settings, check to make sure they are set the way they should be (see device documentation).

Things to check:

In menu are speakers (audio area) switched on or off?

If you put sound all the way up and listen right at speaker what if anything do you hear?

If using a cable or sat box is sound turned down on it?

Is sound muted on set or the box (if used)

Do you have sound with a DVD etc hooked via the rear jacks?

A few sets have a slide switch on the rear= internal or external speakers--is it set to internal?

failing all of the above you have a audio circuit problem

Check all your channels. If you are getting sound on some channels but not others it is a good possibility that your SAP setting is turned on. Simply go into your audio menu and disable the SAP. Not sure about your model tv but some Tv sets had a switch on the back to disable the speakers and some have a setting in the menu to disable the speakers. If you have a digital cable box hooked to the tv it is possible the cable box volume is turned all the way down which will override your tv volume. Check these options and hopefully one of them works for you.

On remote hit tv button hold set up until it flashes twice. Hit 11758 it will flash 4 times hit set up to lock. Now hit tv button and the volume should work on set.. Hope that works

Are the RCA cables matching(in tv to out sources.audio to audio and video to video)?And make sure the cables are in working condition
