I disagree with given info.
LCD tv does not have any YSUS board inside.
I agree that capacitors can be cause of problem so check power supply board for bad/ leaky/ dried up capacitors and replace them with same ratings.
Check back light inverter board as well s they got failed and causes no image in lcd tv.

Could be bad caps or the YSUS board or a component on it has failed. I would go with recaping the bad ones on the PSB-power supply board first. this is the first signs of failing caps. Sound but no pic. When caps go bad they cut off the trace circuitry to the other boards they are connected to. Soon enough you won't even have sound, just a blinking fault LED at startup.

SOURCE: Samsunb 4051: TV screen turns off sound stays on.

Most likely this set has an "integrated" inverter, as most samsungs do--and this DOES sound like an inverter problem. Make SURE thought, there are no more bad "10 volt" caps on the power supply...ALL of them need to be replaced no matter HOW they look.

Find the settings menu in the TV. It sounds like you turned the green off completely. You can usually set the hues and colors and adjust for your preference or for lighting and such. Hope that helps.

Black screen and whistles


Sorry to say that it sounds like the high voltage went out on that one. The sound that you hear is probably the high voltage arcing across the flyback transformer. Dont try to make any repairs here. The unit has at least 25,000 volts in there. Even long after it has been unplugged. I'm not sure what size TV that is from the description, but you would be looking at replacing the main deflection board, which may well exceed the value of it.

TV was playing, then the screen turned black.


If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.
