Hello and sorry you're having problems. This issue can be caused by two possible causes: 1) The Mainboard in the TV has failed.2) The software has failed. Let me know if you are able to get into the MENU on the TV and navigate through any options- or does the set automatically click on/off every 15-20 seconds while you try to do that as well please?
Customer: replied 8 months ago.
No I cannot get any picture other than the Samsung Smart TV logo, I have to unplug the TV to shut it off.
Expert:  Aric replied 8 months ago.
Okay, this does point generally to a faulty Mainboard. Please try this reset as an attempt at a fix and also a test to see if it helps with the issue. 1) Disconnect the set from power. 2) Remove any HDMI cables from the back of the TV. 3) Press and hold the power button on the TV itself (not the remote) for 10 seconds and release. 4) Plug the HDMI cable(s) back into the set and then plug it into power. Does the clicking occur right away? If not, press the power button once and let me know what happens.

No thanks- I don't use the phone call service. Try those steps above that I just posted and reply back here with results.

I don't know where the power button is on the TV.
Expert:  Aric replied 8 months ago.
Hang on while i pull that up please.
Expert:  Aric replied 8 months ago.
Lower left hand corner of the TV. It doesn't show if it's just around the back of the set, or on the front in the manual. It just says there is power, channel, input and volume on the lower left corner.
Expert:  Aric replied 8 months ago.
Were you able to find the button?
Customer: replied 8 months ago.
There is no change.

What is the cost to change the Mainboard?
Expert:  Aric replied 8 months ago.
Okay, and unfortunately that was all you can try on a user level- aside from leaving the set unplugged from power for several hours in the hopes that it resets. Otherwise the "Mainboard" in the TV (which contains the processor that switches the Inputs, shows the Smart TV logo, etc.) has failed. If you have this done at a shop you're looking at around $250 parts and labor (with the board itself being rare and hard to find in stock). Some shops do repair the board as well. If you're looking to go that route you can use the link below to locate a shop in your area: http://www.tvrepairpros.com

Or if you're a do it yourself type, and want to search and try to track down the board and replace it yourself, the part number for the board is: BN41-01605A. Other than that, I'm sorry for the bad news and wish there were a quick fix. If you need further assistance let me know.
