I think that in the back on the upper left-ish back panel there should be a cover to take off. This is judging on mg 2012 42 inch samsung lcd tv.

Push the "menu" button on your remote
Tab over to the "time" menu
check all the settings in there, turn of the sleep timer etc...

Try a factory reset
Push the "menu" button on your remote and go to settings, scroll down and push reset.

I hope this helps

Sorry bad news these TV's work off of lights that shine thru the back of the screen if you heard a pop it was the power board that turns on those lights not an easy fix sorry.

Rina -

Are you sure about that product ID? I found nothing with CDX prefix - perhaps you should try this -

http://www.samsung.com/us/business/support/owners/product/SCX-3405FW/XAA

This is as close as I could find and I've been servicing laser printers of many manufacturers since 1998.

Your question does not explain the problem you are having; please try to include that in your next question - I have to know what you are working with before I can give you an answer.
