In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hi Tom

Sorry to hear about your Lemon. I learned about Samdung products awhile back.
I refuse to buy any of their products because of their bad attitude.

The Non Innovators who reverse engineer to get ahead in the market & program devices to work super fast on benchmark tests.

A bit like FolksWagon did with falsifying dynamometer results for EPA readings.
I know all businesses can make mistakes and make poor choices. But, we really shouldn't support companies that blatantly falsify to get better market share.

All electronic devices (inc HD TV's) have problems with Electrolytic Capacitors fizzing out. It's a huge problem.
But I'm sure "some" companies buy underrated parts to insure they don't last too many years.
Go with respected companies like Sony, Panasonic, Hitachi etc.
and check the following before buying.
Warranty period
-(Nice if you can get 5yr like my Mitsubishi Electric Fridge)
User interface - The on screen controls. Ease of Use.
Input Ports - USB, HDMI etc
The video codec's that are supported. eg .avi, .MP4 etc
the more the better. (Look how many codec types VLC support)
Plug a HD drive into the USB. What movies can it support?

Cheers

you could do a force back light test .
Remove power cord, remove 1 side of the cable going between the main board and Power board. Plug in power cord and see if you get back light. The light should be on FULL since the main board is removed from the equation.

If backlight is fully bright then it could be the main board causing the problem. Any time you cant see main menu of the TV it also could be main board problem,

If you do force backlight test and the LED still do not look like htey are firing then it could be Power board or LEDs themselves.
Check voltage on CN802 and CNI801, proper low voltage should be listed there
Also CN201 pin 14 should be 1v-4v -> thats the diming signal

The most likely cause is a problem on the power supply take a look at the power supply board if the capacitors are slightly bulged on top they need replaceing
