Question about LG 42CS560 42 Class LCD HDTV
We got this tv 4 days ago as a gift. It was brand new in the box. All of a sudden it turns off by itself and every few minutes it will flash back on for a few seconds and then off again. The power light changes from red to blue and sometimes white, then back to red. I have tried changing surge strips and plugging it directly into the wall.

The first thing is to take out the batteries from the remote when the problem acts up. If this fixes it, replace the remote. If not, go to the front of the tv and find all the buttons that are on the tv. Start by pushing all of the buttons one at a time. They should all feel the same and sound the same when you push them. If one of them does not, then the buttons are the problem. If they are good, take to a repair shop. The main control board is bad.

You will need to replace the mainboard, you only need to be sure your cable box is connected to the TV using ONLY one cable because if you use HDMI and another cable (ie. HDMI and COMPONENT) could show that sympton.
First try unpluggin everything from the TV and try to turn it on, if you continue with the trouble then you can be sure you need to replace the mainboard.

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.
