    Specifically for the Viewsonic N3752 w I held down 2 volume buttons at the top of the TV together , this does a menu lock that is displayed on screen, repeat the procedure to unlock. This seemed to work. I now can control volume through either source.

Either the button is jammed on the remote or the TV itself. Try removing the batteries from the remote. If the doesn't work, it is probably the actual button on the TV, in which case you would have to try and pry up the button and manually pull up the pressure pad underneath.

SOURCE: Volume increases by itself

This could be a sticky button or a bad key controller! The key controller is the button board, this stream the commands to the main board (main unit). not to hard to replace, if your somewhat handy! But will require the case (back panel) to be removed. Good luck, hope this is helpful!

SOURCE: TV volume increases by itself and doesn't decrease or respond to the remote control

Apparently this seems to be a known issue for this model. I called Phillips and they did not even bother asking me to try things like switch off and on again etc...They just said they are going to send someone to pick it up and fix it. I would suggest to everyone to do the same since it has to be free of charge because the problem appears in pretty much every tv set of this model.

SOURCE: LG TV 32LB9D VOLUME STUCK AT 100, NO RESPONSE TO REMOTES

The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.

Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.

If you use a digital cable box, it could be that the volume on that isn't turned up all the way. I didn't even realize the box had volume controls until 2 years after I got it...makes a HUGE difference now

Having connected up my PVR915OT I am unable to increase the volume on the TV to a reasonable level of volume using the Humax handset- can you offer a solution please?


As far as I recall, the volume control on the PVR remote only controls the volume from the PVR. So, select the volume fully up (using the PVR remote) then increase the volume on the TV (using the TV remote) until it's as loud as you can stand. You can then adjust (decrease) the the volume to suit using the PVR remote.

How do I change the power supply for my Viewsonic 37'' Model # N3760W LCD TV. It keeps turning off when I change channels and adjust the volume. I cant order one from Viewsonic.


Very carefully. I only would do it after you have verified the warranty is expired per Viewsonic. If it is OOW, then you can call them for a service manual that contains schematics, troubleshooting flowcharts, etc.

Volume automatically goes to maximum on TCL TV


The volume (+) button on the TV is stuck or soiled if the volume automatically increases when the TV is turned on. To find out:
  1. Turn off the TV.
  2. Press and hold the volume (-) button on the TV then turn it on.
  3. If the volume doesn't automatically increase, you have a stuck button.
  4. If it does increase, you have a faulty key control board.
  5. In either case, you have to replace the key control board.
To find it out further:
Warning: Beware of electric shock.Please do not proceed if you do not have the skill to do the following.
  1. Unplug the TV.
  2. Let it stand for 15 minutes to allow voltages to drain completely to avoid the risk of electric shock.
  3. Remove the screws securing the TV's back cover and pull it off.
  4. Disconnect the cable that runs from the main board to the control key board.
  5. Turn the TV on using the remote.
  6. In this manner you can use the remote control to run the TV while waiting for the control key replacement board.
To do a hard reset of the TV, unplug it and let it sit for 2 hours or long enough to completely drain the internal voltages.
