People are giving away their older TV's as they upgrade to new wide flat-screens nowadays. That makes your TV not worth fixing. Keep checking Craigslist and your local thrift stores for one that's cheap or being given away.
The clicking you are hearing was probably always there, it's just that when something goes awry, one pays closer attention.
What you hear is probably a relay that connects power to the rest of the set.
Since our sets can respond to a remote, they always have a little bit of life to supply power to the infra-red receiver so it can respond when 'off.'
I see two possibilities; the relay itself has burned contacts and not always 'closing' as it should, or, the high voltage circuit is failing to turn on as it should causing an excessive current to flow for a moment and a protective circuit to trip and disconnect the power from the main supply.
It probably will get worse if the problem is not found and could damage other circuitry as well.
Good luck finding a TV repair man who isn't deceased or out of business but I do recommend you try to have it repaired.
Once repaired, it will outlast most any panel/flat screen-type TV as it appears nearly all of them are failing much too early in life.
You can check by entering just "LCD," "plasma" or "projection" plus TV in the search window here.
Pull the back Off Disconnect CRT board connected at End of picture tube then turn set on and see if it comes on with volume, high voltage you can feel front of tv for static elect.... Let me know what happens then i can tell you what is wrong with TV.
IF THIS IS A LCD---TURN ON, AS NORMAL AND HAVE A SIGNAL INPUT,,CABLE ,SATELLITE CONNECTED TO THE ANTENNA INPUT .MAKE SURE YOU HEAR SOUND.. HOLD A LIGHT (THE BRIGHTER THE BETTER) IN FRONT OF THE THE SCREEN ('BOUT 3 INCHES)--IF YOU SEE A DIM PICTURE---BAD SCREEN AND THATS BIG BUCKS---IF STILL NO PICTURE--CIRCUIT BOARDS AND USUALLY THATS BIG BUCKS!! GOOD LUCK
