How to replace a tube holder or ballast

It is just a florescent tube. See the videos.

A ballast keeps a tiny charge running into devices that would otherwise need to "warm up" in order to function properly. Non-flicker florescent lights use a ballast so that they come on right away when you flick the switch.

Generally you can't run ECO or ALTO tubes (less mercury) in fixtures meant for regular Rapid Start/ Preheat tubes. Other than that Old tubes near end of life sometimes do that.

a ballast is like a transformer, as an example, florescent lights require one between the power supply and the tube.

no , that can't happen: your screen has tiny florescent tubes and, a ballast to light up the screen replace the ballast it is located in the bottom middle of the screen frame between the hinges; ebay sells the part.

I strongly believe that one of two things has happened:
1) the back light 'florescent tubes' lamp ballast power supply board has gone out.
2) One of the florescent tubes has failed taking out the lamp ballast.
Is the TV still under it's factory warranty?
If it is not I would call around some TV service providers in your area and get some estimates of repair. Fairly common item to go out.

there is either a bad connection or no juice getting it the fixture or you have a bad ballast [transformer]..

lcd sets use florescent tubes to light the display and, a ballast to power the tubes just like the lights in an office ceiling.
the tubes are called cold cathodes and, the ballasts are called inverter boards. replace your inverter circuit board it connects by wires to the cold cathodes so; isn't hard to find.

are they the florescent tube type?? i suspect that the ballast went bad

Inside a fluorescent light, electricity is delivered to a ballast, which sends a spark through the mercury-vapor-filled tube (or bulb), creating light by activating phosphors that coat the inside of the tube. If any of the components are faulty, the light won't work right. Once you pinpoint the problem, most fixes are very easy. Remember to turn off the power first! Old bulbs blink off and on just before they die; repairs are often simply a matter of replacing the tube or bulb. This problem may also be occurring because of poor contact between the pins at the ends of a tube and the tube holders. If the pins are bent, use needle-nose pliers to straighten them. Clean up the pins and socket contacts with fine sandpaper, and brush away residue. Though gray bands at the ends of tube are normal, black bands indicate that the tube needs to be replaced. If only one end is dark, turn the bulb end-for-end. If the tube is new and these fixes don't work, you may have to replace the starter or ballast. Some fixtures ("A-rated") are quieter than others are, but most fluorescent lights have a slight hum. If the sound seems too loud-- or if you can smell electrical burning-- shut off the power. The ballast is probably either the wrong type, improperly installed, or defective. Replace it or call an electrician. Brand new tubes tend to flicker, as do bulbs that are cold. If an old tube still flickers after it has had a chance to warm up (or after you've warmed up the room), rotate it a couple of times in the tube holders. Try cleaning the tube's end pins. If it still doesn't work, replace it. If only the ends of the tube glow, either the starter or the ballast is defective. Replace the starter, then the ballast.
