Question about Philips Magnavox 27MS343S 27" TV

2 Answers

Volume keeps going down by itself. I'll use the remote to turn it back up and it goes back down to zero again.

    I picked up a Magnavox TV about 26" to 27" from the curb. When it was first plug in there was sound as it was changed from channel to channel. I unplug it and on pluging it in again found that I had lost the sound. How do I get back the sound

Thanks but the TV is now working well when it was tried the next day. He has been giving the sound for several days now. Thanks so much for your advice.

It's rare but happens. Sometimes the volume button (or rather the plastic piece that activates the button when pressed) can get stuck. That or there has been a cleaning chemical leak down onto the button on the board itself and corroded it, causing a constant short.

As for the second Q, I feel that your TV may have received a shock through the audio line and the audio amplifier may have taken the hit. These problem can lead into multiple bad compontnts, such as a bad SMD IC on the bottom of the board.

Try removing the batteries from the remote after you set the volume, just to determine if the remote is causing the problem or not. I have seen stuff spilled on remotes and they just go crazy.

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.

Volume goes down to 0 and the menu goes on and off.


A bad connection on the small signal board may be the problem! Have a Tech check this connection, it may be to tight due to the heat shrink tube. Have them peel it back to reduce the strain! Should work then!
