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 also had this same problem. Both the original remote and my universal remote failed to give any response on the TV. Normally the green light flashes when it receives a command from the remote. Called LG Support and they made me an appointment with a local repair company for 3 days later. This seemed pretty quick compared to other companies repair times I'd read about. However next day the repair company called to say it would be 5 more days before they could get a Tech to my location (downtown ATL). 8 days was a long time to wait but once tech arrived he diagnosed it to a bad board and simply went to his truck and swapped it out with mine under factory warranty. Everything has been fine since.

Throw the TV away and vow to never buy something from this manufacturer again.
They not only refuse to help me with the same problem, but they lied to me and created a false comment on my file.
My TV did this only a few days out of warranty. I called them, not expecting them to warrant it, but to possibly give me some ideas for the problem. I spoke with a manager who volunteered to repair it "just this one time" even though it was officially out of warranty. I thanked him over and over, but the next day, suddenly no one 'knew' the conversation took place. They told me they would investigate (on July 2), and I waited until today to call them and they told me that their notes said I was advised that I would have to pay for repair. They told me of a conversation I had on the 3rd with Ed. There was no conversation with anyone on the 3rd, and no Ed.
This company appears to be sleazy. I'm sticking with Sony or another company from now on who tells the truth.

Try the setup program. When you get to the main setup screen, look for a reset all to standard setting. That may solve the problem. If it doesn't then the sound module may need to be replaced inside the TV.
