I HAVE SAMSUNG TV UE46C6000AND IHAVE PROBLEM INTHE WITH TIS MESSEAGE APPEAR IN SCREEN"NEW DEVICE NOT FOUND" AND "USB2 POWER OVERLOAD";WHY IT IS APPEAR AND HOW I REMOVE IT FROM TV SCREEN?

I think you have two errors:
1. New service not found
2. usb power overload.

#2 means that whatever you have plugged in is taking too much power for the tv to run it. Unplug it, and see if things work better.

Use the remote to disable the apps the tv is running, they are called 'widgets' and you have them turned on. It will be inthe menu for internet options

Dear inVaUSA, I followed your action and contacted 1-800-SAMSUNG but did not fare as well as you did. I was told there is not a firmware update nor a patch to fix the "New Device Not Found USB1 Power Overload" even after I read your post to the support representative I was dealing with. She told me that it is a PlayStation issue even though I have never connected any USB device to any USB Port on my Samsung TV. Could I Please trouble you to send me the firmware update you received from Samsung `in a private message or to my email address if you prefer. Thank you!

Id say U have problem with the power supply or the power button - dont muck around with it take it to a repair shop.....

Inspect for damaged pin on INPUT 1 socket. (left most of the three HDMI connectors)
A quick pull on the cable can damage the pins.
=== If you see mis-aligned pins then please power off the set before making corrective action. ===
============== Here's a textbook instruction from Mitsubishi
If the New Device Found Screen Displays No HDMI Control Option If the New Device Found screen shows no option for HDMI Control, one of these conditions applies: • HDMI Control is turned off in the menus of the new device Action: a. Highlight EXIT and press ENTER to close the New Device Found screen. b. Display the device's setup menus and enable the device's CEC capabilities. c. Wait for the TV's New Device Found screen to appear again. d. If the New Device Found screen does not appear, power off the device. Power on the device and wait for the New Device Found screen to display with the HDMI Control option.
Next time you see the NEW DEVICE FOUND screen pop up.
Toggle the CEC field (on the right side of the pop up) to OFF.

download the firmware and problem solve T-MSX5IBRC-1004.4

hi ... can i know why you did not accept the solution?

I called 1-800 SAMSUNG and they had a firmware update that fixed the problem. I don't know if the update is available on their website, as I had downloaded a firmware update 2 days previous and this was a newer version that they sent me via email.
