HI,
if the display shows a progress bar when lowering and increasing the volume, that's a system built feature. you will not be able to remove that feature.
SOURCE: can't increase & decrease the volume
Double check your connections. Still not working fine. Remove the input jack connector and try to touch or hold the tip of the connector, also adjust the volume of the speaker, you should heard loudly the 60 hertz sound of your body signal. Otherwise you have a defective amplifier in the speaker system.

Well, the nice thing about the newer amps is that the actual amp circuitry is all contained in a module and you don't have to do much troubleshooting. Just replace the module for that pair of channels. Bad news of course is the modules can be pricey. Should say right on it the part number, order it from mcminone.com or whoever, solder it in, use new conductive grease (many times I think these modules fail because the grease gets old, the module overheats and toasts) and you should be fixya'd
SOURCE: Why does my RCA TV cycle through channels on its own?
this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

Unplug the power and let it sit. Plug it back in and it should fix. Worked for me.
