Since remote does not work, try taking out batt and turning on by set. See if still turns up. It could be that the up button is jammed inside set. Does everything else works? See if you can go to menu and turn speakers off, this will allow you to work on set and not worry about noise.

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?

I had this problem as well guys. Just found a fix thought i'd share.
I simply went into menu>setup>reset . This will perform a factory reset, and you shouldn't have that K or the volume problem anymore.
I tried all the fixes involving volume- input- nothing worked. I tried volume- ch- but that K never changed colours.
It all came down to a simple menu option reset.

On the TV-use your finger to adjust the volume level, about midway, then use the remote to shut off the tv, then turn on tv with remote. Volume level should be better! If still not loud enough...using your finger on the tv...turn up volume & repeat remote steps.
