I just recently encountered the same problem with a Sony Bravia KDL-46EX500. It started out of nowhere but after what seemed to be an update from the cable company. The volume would go down to zero and the LCD light on the front of the TV would continually blink. After trying many "solutions" including resetting the TV to factory defaults, , I removed the batteries from the cable universal remote (Comcast Xfinity) and used only the TV remote and the TV worked fine. When I reinstalled the batteries into the Xfinity remote, the problem started again. So I tried using some of the other codes listed for Sony televisions and found that an alternative code (10273) would also control the TV but not reduce the volume automatically. So, in short, try looking for a different, usable code for any universal remote that you may be using - it may be the problem.

When i turn the tv. on, the volume line appears all the way to zero. if i turn the volume up, it goes up but when i release the up button the volume goes down all by itself.


It sounds like one of the volume down buttons is stuck in the activate position. The same as if you were holding the down volume button continuously. It could be either the volume down button on the TV or the remote. I would try remove the batteries of the remote then adjust the volume by the TV buttons.


If the volume doesn't go back down then the remote is the problem. In order to fix the remote you may need to take it apart. This is normally easy to do just locate any screws that may be holding the remote together. If you don't see any screws then you will need to pry the two sections apart. Separate the circuit board and rubber buttons and clean them both with some rubbing alcohol and reassemble it. If it still has the volume issue you may need to replace it.

If the problem persists with the remote deactivated then it's the volume button located on the TV. That is a little more difficult. You can try wiggling the button or some canned air (used to clean computer keyboards) to blow it clean. However it may need to be disassembled to gain access to the switches for proper cleaning.
Hope this helps.

No volume without holding remote button


The volume on either on your Remote or Tv is stuck down. This can be caused by spilling Liquid onto the remote (we all do it) you can test which one it is.

take the battery's out of the remote and turn the volume up via the Tv volume button on the telly. If this stays at the required Volume Then this means that the - volume button is stuck down on the remote. Try and clean it with something like a baby wipe or something similar (not a sopping wet cloth) If this does not work then you may need a new remote.

Hope this Helps

Menu Trouble


perhaps the volume down button on the TV is stuck. It could be either physically stuck, or the electronic logic could be messed up. Just to rule out a problem with the remote, take the batteries out of it and then adjust the volume at the TV and see what happens.
