Normally problem is defective switches rather then mainboard.
If volume + is coming on chances are that the switch is mechanically stuck or electrically leaky.
If you are technically able I can guide you further.
It could be the problem in the power supply because of bad caps, or bad inverter circuits, or worst will be bad lamps. Look for bad caps first and report back what you see so we can guide you further, see example of failed monitors due to bad caps and lamps: http://s807.photobucket.com/home/budm/allalbums
An unusual problem for a flat screen monitor.
I suggest you connect the monitor to another PC to see if the problem persists since it could also be caused by the video card (or circuit, if on board).
Check your cables making sure they are solidly connected and wiggle them to see if you can cause the problem to come or go away; this would crudely check the shielding of them.
This kind of aberration could easily happen with a conventional CRT monitor if power supply filtering was failing but as mentioned, uncommon in a monitor that is essentially digital.
I don't normally respond to any questions on here anymore so forgive the delays in response.
The missing capacitiors are due to the board being made for a series of monitors using different power settings and having other things added to the mix like sound amplifiers etc (yes they live on the power board) so not all component holes will be filled unless the board is from a fully optioned model.
The fault you will be looking at can vary depending on the board manufacturer. If you can email a photo of both sides of the power board I will highlight the areas you will need to check. mailto:email@example.com
the problem is always corrosion on the circuit board that has the buttons disassemble the flat panel remove 3 screws that hold button board on disconnect the tiny cable from the button board use a tooth pick and clean inbetween the solder connections where the ribbin cable plugs into button board
