Question about Samsung LA40R81BDX 40 in. LCD TV

Samsung LCD LA40R81BX/XFA TV doesn' switchon/ keeps clicking

The TV does not switch on and keeps repeating two distinct clicking sounds successively one slightly muffled followed by sharper one. They keep alternating. I did not leave it on for a long time for the fear of damaging the set. This happened while I was watching the TV and struggling with the music system connected to the TV where one of the CD was malfunctioning. Can there be a connection to these events? What can be the remedy

Nothing to do with connecting the TV to the stereo, more likely you are having power supply failing, the clicking sound is from power relay, the power supply may have unstable DC due to bad DC filter caps, bad solder joints or loose connections.
