The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so.

Hi there are a couple of hings that could be bad with your tv. Your screen or your t-con board would be the most obvious. Screens are expensive to replace so I would try replacding the t-con board. The t-con is the board thattransfers your signal to the lcd screen. It is usually located on the top center of the tv. You would need to open up your tv and get the part number fro the board.You can get get parts for this tv at www.interliquidparts.com

Hi Patrick,This is an indication of out-of-regulation condition on the power supply board. This is caused by faulty electrolytic capacitor on that board. Most it has a physical indication of fault like bulged/dome at the top and can be easily identify through visual inspection. See sample picture below.If you're unit is not under warranty period, open the back cover and inspect the capacitors on that board. If you found it, replace it with same capacitance and working voltage that is printed on its body itself. Watch the video below for more info regarding electrolytic capacitor.(do not delete) Another option is to replace the entire power supply board if you can't troubleshoot the unit yourself. This is more convenient if you are going to DIY because no soldering required. I have also a link where you can buy the capacitor kit. Click it here.Let me know if you need further assistance.Hope I helped you.Have a nice day!Thanks for using Fixya.

This will not be easy to be 100% correct as to what part is bad as you can see in my pictures here.
It can be bad main board, T-CON board, Bad LCD panel.

I would try new T-CON since it is the cheapest part, not worth to repalce LCD panel.

I'd say what you really needed in the first place is this:

As to why it went dead...I think (and you should pray) that it's because the original problem just showed up again.

The original problem being the power board not functioning right and NOT what Samsung told you.

Chances are I am wrong, of course.

But I'd bet my lunch over anything any large company service rep reads you from a book.
