Try removing power and all connections for 10 minutes and then try just power one more time. If that still clicks it needs repair. There are no user serviceable parts and a TV Tech doesn't ask but dives into the service manual.

I have an old LG PQ6000 42". Up until now it has worked perfectly, but the other day I had it turned on. I wasn't in my room when it happened, but I heard a loud noise and when I came back to my room the tv was turned off. Tried to turn it on again but it didn't work.
Now it does this like once a minute:
