SOURCE: Loud, high pitched hum from speakers . . .
This is GroundNoise from the TV's Backlight.
Sorry, but unless you are a Technician, you will simply need to ignore it.
If you are a technician, you can fix this by grounding the Audio ICs to the Power Supply (details not provided)

How are you connecting your laptop to the samsung TV? Is it DVI/HDMI or thru more-common S-video cable? I have successfully ported laptop screen to TV with S-Video. After you connect your S-video cable, right-click on blank desktop of laptop and bring up the Display Properties (usually the last entry on pop-up menu). Got to last tab, usually called Settings. You should see two monitors displayed on top part of this page. One of these (most likely #2) is your TV. Click on #2 monitor and check the box that reads "Extend my Windows desktop to this screen" (or words to that effect). Be sure you have the TV turned on and facing you because you may find yourself clicking on icons on the TV screen. You'll probably have to play with which is primary display because some video players have trouble playing to a secondary screen. You may also try the Fn+F8 (CRT/LCD) button on your laptop (those are the keys on my Dell). That may turn on the TV-out on the laptop. Lastly, remember that this will only get you video. You'll have to connect a 3.5 mm cable to you Line-Out port on the laptop and connect it somehow to your TV or SurroundSound speakers. There should be a audio-in port on those other devices for that. Or you can just play the sound thru your laptop speakers.
I'm not that familiar with the DVI-out but I suspect that it would work very similiarly. Good luck.

The blinking indicates that the protection system of the power board from the tv has detected a short on one of its outputs and has cut the power to it to prevent further damage - the clicking is made by the main power relay being disengaged, repeatedly, by the protection.
You should count the blinks - it's an indicator of what might be faulty. If the blinking is continuous then the problem is either in the control processor or the power source itself. To find out which and replace the appropriate board the tv will have to be opened and inspected.If you;re lucky it will be just the electrolytic capacitors on the power board. This is how you replace them

If there's more then you will have to check the voltages on the power board to find out what elsehas failed . If you can't do that then it's time to call a repairman.
