Hi,
Keep the Unit Unplugged for few minutes, say 30 minutes and then Turn the TV ON?
If the problem remains, i am Sorry for the Bad News.It is the power board(also known as SMPS) There may failed capacitors(not capacitors) in it. There are three connectors(for Y-Main, X-main and logic board). Disconnect them one by one and check again for the clicking sound. For example you disconnect connector of Y main and the clicking sound goes away, that means the Y main reeds to be replaced. The order of removing connector is Y first, X second and logic board third. If you want to repair it yourself then you should be having proper knowledge about the internal circuitry of the TV.
If you wish to Call Someone for Repair, I would estimate around $300-$350( minimum) and the max would be around $500-$600.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

In hdmi i only get standard picture mode??
Have you tried another source on the HDMI to see if you get the same results? If not then the source for some reason is locking out those modes. If the second source doesn't work then it is a feature not available while using HDMI.
My Samsung plasma TV just developed 60 cycle hum.
If you have a cable box connected to the TV disconnect that from the TV and see if the issue goes away. If it does then I suspect there is A.C> leakage in the cable box or somewhere in their wiring. Please take a few moments to rate my answer. Thanks...

if you not need replaced main board you can use cable box or tv converter box
