When i turn the tv. on, the volume line appears

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.

The down volume switch in your factory remote is stuck. Buy a replacement universal remote. They start around $5.
