My TV had a simular issue...delayed power-on with repetitive clicking. I found a post at Techreport.com about bad capacitors on the power board. This and other Samsung models seem to have an issue with these components failing. I replaced the capcitors myself last night, and the tv is now working perfectly. Cost me about $15 in parts and an hours time. Hope this helps!

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Hi A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed. This will cure the problem as they overheat being sat next to a heatsink that gets very hot! Try and change them for the same 3300uf but a higher voltage. Hope this helps
The problem is inside the vga hdmi board ,i have repaired 2 of these
units the 37 inch version and found a bad 100 microf 10 v capacitor . a little bit of soldering/de soldering skill is needed .
cost of cap 0 dollars got it from old radio.but it takes along time to repair-you have to remove the back cover and note lot of screws .ernie
There are likely to be many poor connections in the power supply section that are causing this. If you can solder and the unit is no longer under warranty, you can try resoldering any connections that appear grainy or have rings. That may resolve the problem. If not, than one or more capacitors have changed value enough for the internal circuits to mal-function. This will take some test equipment to locate easily. Try resoldering first and update this with the results. I'll try to locate the most likely parts that could cause this.
Click on the display button (upper left corner) as a short term fix - it will turn it off immediately - not sure of how to permanently solve this though.
the 3d effect tells me that your convergence ic's have blowned. standard for these sets.. not to much of a difficult repair. repair them all the time..
