Question about Samsung TX-R3080WH 30" TV
I will plug in my tv and all I get is a clicking sound and the red light on the power button flashes. It has done this to me before but not for this long. It just keeps clicking and clicking. It is approx 2 yrs old.

Hi there, your instruction manual should have a trouble shooting section, and will tell you what various warning lights are indicating (ie the Lamp/Temp lights will flash in a particular sequence), and will give you the probable cause. In some cases, it could be blocked vents (dust causing overheating/shutdown), or just the lamp failure or faulty switch (indicating loose cover).

This denotes a power supply problem. The trouble could be in the low voltage or the high voltage supply. You will need a schematic and at least a multimeter to even beging to troubleshoot this problem. If you do not have a background in electronics. I would suggest taking the set to a TV repair shop.

I had the same problem with my Samsung TV Model: TXR3079WHX. I troubleshot my problem with a can of component cooler from Radio Shack and found my problem to be a defective voltage regulator, identified as "QR015" on the main circuit board (the same board that contains the high voltage section).
Before I proceed any further I need to strongly warn you. Do not attempt to remove the back cover, troubleshoot, repair or perform the actions that I have done, if you are not a "qualified service technician". Removing the back cover exposes you (and anyone else) to harmful and deadly electric shock, even though the TV may be unplugged from the wall outlet and turned off. You (or anyone else) can be seriously injured or even killed. If you are not qualified, play it safe by allowing others who are qualified repair this for you.
The defective part (overheats and shuts your TV off) is voltage regulator manufactured by Fairchild. The part number is KA75450ZTA. This part is available from Mouser Electronics for less than 20 cents plus shipping. In order to replace this part a qualified technician will need to remove certain cables and unscrew the main board to allow access to desolder and solder the new component.
Hope this helps.
