My television turns down the volume on its own without me pressing anything on the remote
SOURCE: ViewSonic N2750w 27 in Volume turns down by itself
Could be a problem with the down volume button on the tv. the board
it's on ir its harness. Check them all. Make sure the volume buttons
plastic actuator moves freely and is not stuck.
If these parts are all good, you have a problem on the main board. You
may have to trace the control lines as far as you can and check any
capacitors along the way. If you have an oscilliscope you can test the
lines to see if the up volume is working correctly. If there is noise
on it, you might find a bad capacitor if you can trace it back far
enough. Schematic helps here.
Of course, make sure nothing is shining on the sensor window on the TV.
You might want to scope that line as well (IR sensor line).
If none of that helps, get hold of Viewsonic and find your closest service provider. You can order a main board from them.
Of course, you could try just using the audio out jacks to an amplifier
or a surround sound amplifer. Then you would use the remotecontrol for
the surround sound system to control your volume.
Bet you were going to buy one anyway right?
