Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

It sounds like the main board or screen may have gone

Testimonial: "A quick one to respond with a good answer to the problem."

SOURCE: No Sound on Samsung HDTV? But there is a picture...?

have you tried to umplugging the tv and let it sit for a little while. I would unplug the tv like before you go to bed and plug it back in in the morning and try it

Testimonial: "Well, I unplugged it for several minutes, and that was enough... thank you very much!"
