Samsung tv picture went black

SOURCE: Samsung LCD Tv has no picture but sound

I took it back and got a full refund.

SOURCE: sound yes, but no picture on tv

If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

Sounds like main board failure and or power board failure. You need to contact manufacturer and describe problem for tech support. Some of the parts in Samsung TVs have lifetime warranties. Change out of two board is about an hour job and service call is usually comped. Hope this helps. J

Probably need a Main Board. Take it to an Authorized Samsung repair shop for troubleshooting. T-con would be another possibility and I've even seen the LCD Panel bad on this model
