Question about Samsung LN46A650 46 in. LCD HDTV
Check the LVDS cable !!! It is the cable that supplies the video signal from the main board to the LCD controller. If wiggling the cable clears up the problem or invokes the problem, you need a new LVDS cable!

Hello Ed -
You mentioned a "box" so I assume you're using a cable/satellite receiver or digital converter, I would suggest resetting the receiver/converter. Some can be reset by simply switching off and on, some have a reset button and others need to be disconnected from the power supply for a minute or so. Reset the box, then try the TV again. Sometimes the software/firmware in these boxes can crash and re-booting the box will solve the problem.
If you have a DVD/VCR or game system connected to the TV, you should also test whether have audio on the TV from any of these devices. Finally, if the TV has a headphone socket, try plugging in a set of headphones to check for audio.
If you have audio from another device, the problem is likely to be with the "box" rather than the TV. If you have no audio from any device, try restoring the TV settings to the factory defaults by holding down the EXIT key on the Samsung remote until a message appears on screen saying "Resets all settings to the default values". When this message appears, you will need to confirm you want to continue with the reset. You will lose all user settings for video and audio, so you may want to write these down before you reset.
Finally, there is a firmware upgrade for this TV available from Samsung. Please check your current firmware version before installing the update. Click on the link below for the Samsung download page, then click on "Firmware" in blue text. You will need to download both the Upgrade file and the Upgrade guide, which contains the instructions for installing the upgrade:
If you get as far as installing the upgrade and you are not sure how to do it, please let me know and I will be happy to provide detailed instructions.
If you've done all of the above and you still have no audio from any device or headphones, it's likely that the Main / AV board (motherboard) in the TV has failed and will need to be repaired or replaced.
Hope this helps. Please try the suggestions above, then let me know if you need further assistance. You can reply to me by clicking on "Add a Comment" below your question.
