SOURCE: no picture

The way to isolate the failure to the power supply would be to measure the voltages going to the backlight inverter board. If all the voltages are normal then is more likely a defective backlight inverter board or LCD controller board.

I have a 60 Inch LG Plasma TV Model Number 60PV400-UB I have sound, Remote chances channels and can tell volume is still working but have no picture.. Just Black Screen

The most likely case is that the 'backlight' has failed.
If you turn-off all the lights at night, you can generally see the feint picture generated by the screen. If you can see the picture it means the backlight has failed. You might be able to get the backlight replaced.
If you can't see the feint images, either the hardware to generate the images has failed or the LCD screen itself has failed.
Unless it's under some kind of warranty you'd need to get a repair quote for it. But if the LCD screen itself has failed, it'll essentially be uneconomic to repair.
Best of luck

My Emerson has no picture but has sound

Is this an LCD tv? You didn't include a model number so i can't really answer, but if its an LCD tv then try shining a flashlight on the screen at an angle, can you see what looks like an image on the screen with the flashlight? Its pretty common for the backlighting in a LCD to fail causing it to appear as if there is no picture but the picture is there just no lighting to make it visible. If there is still no picture with a flashlight up close looking at the screen it could be many things, failed capacitors in the power supply thats preventing the screen from coming on, a bad mainboard that the video failed but the audio still works, lots of options here.

LCD TV Has Sound, Backlights Work, but No Picture

I have been having the same problem with my LG. people say there are bad capacitors on the power supply board. I don't have the know how to replace them and don't have the money to pay. I can get mine to work by blowing hot air with a hair dryer into the back of my tv through the vents over the board. Heat it up for a couple minutes and turn it off and then back on and the picture comes back. I just never turn the set off now.

Samsung 46 inch lcd no picture only sound

Could be backlight or the Invertor. While the sound is operating shine a flashlight into the screen and see if you can see the picture or not then let me know and I will assist you. But I will also need the model number of the set.
