What exactly happens when the set shuts off?...does the power indicator lamp stay on, or does it blink. Also do you still have sound?

SOURCE: 37" LCD Flat screen

Yes it could and most likely is the power supply board. If you look at the capacitors on the board you may see some that appear swelled or puffed up at the top. If you see any that are puffed up they are leaky and replacing them may fix the problem. Some times if the Inverter board is bad it will not let the TV come on. a LED will be blinking. If you have no power at all it is most likely the power supply.

SOURCE: 37 inch LG LCD won't turn on due to power failure

Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.

How can I adjust the picture colors?


There are several performance issues you may encounter with your Protron PLTV-37C LCD television.
Some problems include the television not turning on, issues with the TV's picture and issues with the TV's sound.
Depending on the type of problem you encounter, there are several options available to you to solve it.
Power Issues
Check the TV's main power cord. If it is not plugged in or is loose, securely plug it in to an electrical socket.
Unplug the television and plug it in to another electrical socket.
If the one it is plugged in to currently is bad, the television does not receive power.

Try turning the television on with the remote.
If that does not work, try turning the television on with the power button on the TV's front panel.
If that works, then remove the battery cover from the remote.
Remove the current batteries and replace them with fresh batteries.
Picture Issues
Check the video cables.
If they are loose or disconnected, securely connect them.
Adjust the television's brightness.
If the brightness is set too dark, images on the screen are extremely difficult to see.
Check the power indicator on the front panel of the television.
If it is red, the television is in power-saving mode.
Simply press any button on the remote to bring the television out of power-saving mode.
Audio Issues
Check the audio cables. If they are loose or disconnected, securely reconnect them.
Turn to different channels and adjust the volume.
It is possible that some channels are coming in quieter than others.
Access the audio options from the main menu. Check what audio setting the TV is at.
If it is set to "Mono," change it to "Stereo."
