Question about LG 42PC3D 42 in. Plasma Television
Either there is a crack or other "short" in the circuit board of the remote or something has spilled on it and is preventing contact at those points (that do not work, such as volume and power).
If you're somewhat handy, start by removing battery cover and batteries. If there is a screw (or screws) visible, remove them. Next, very carefully insert a wide, thin screwdriver or other such instrument anywhere in the seam that runs around the sides of the remote and give your screwdriver/what-have-you a wiggle/twist. I would suggest starting near the buttons that DO work. BE CAREFUL as the plastic is relatively soft and can be easily gouged/broken.
Continue around the remove until it splits into two pieces (top and bottom). Check for obvious damage to the circuit board as well as obvious signs of dirt or other debris on top of the board where the rubber piece that contains the buttons would touch it. Use rubbing alcohol to clean both the top of the circuit board and the bottom of the rubber button pad. Snap it back together and insert the batteries.
This works about 75% of the time in correcting an issue such as you describe. Otherwise, it might be time for a replacement -- suggest a "universal" remote from big box store for $20 or even less.

The remote receiver in the TV set, or its associated circuits inside the TV are not working. This would be fully proven by trying another known working remote on the TV set.

SOURCE: can't turn tv on with remote, only manually, when on volume is at 100 and cannot be adjusted with remote or manually. channels cannot be changed with remote or manually. Changed batteries in remote,
replace with new batteries and it works --- so simple
