The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
I do not think it needs replacement, rather some defective capacitors are causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I had a similar problem: TV was blinking every second and channels or volume can not be changed, but I find out, that it was problem with LOW RECEPTION Channel (TV just Stuck on it!) So Try this: Turn off TV, unplug cable from TV, then turn on TV, now you TV must go to blue screen without blinking, so now you may go to MENU and erase current channel from memory, then switch to any other channel, that have a good reception. Now you may connect cable. You should not have a problem again, but if by switching channels you will find another Low Reception Channel -then do it again: disconnect cable, turn off and on TV and erase this channel from memory.I had a similar problem: TV was blinking every second and channels or volume can not be changed, but I find out, that it was problem with LOW RECEPTION Channel (TV just Stuck on it!)

No I do not think that there is an easy fix. But if you know how to solder then take off the back cover and see if there are any electrolytic capacitors with cracked or bulged tops and let me know. See image below . Thats what they look like http://img62.imageshack.us/img62/8481/capacitors3croppedresiz.jpg
IF its 3 months old it must be under warranty? IF you bought it used there ain't no easy solution. Electronic faults cannot be fixed by pressing buttons on the remote!IF its 3 months old it must be under warranty? IF you bought it used there ain't no easy solution.
