main board or power supply?

When i turn my TV on, the LED goes from red (standby) to blue (ON) i can hear a "clicking" noise(relay?) and it shuts off (LED red - standby). Is that the power supply board or the main board? How do i make sure i order the right one? Thanks

@chris2306 with the limited information available, my number one suspect would be the mainboard. I suggest that you follow the troubleshooting flowchart for the power on sequence.

If you have any issues identifying where those test points are, post plenty of pictures of your boards with your question. For that use this guide.
