Possibly. Did the problem start suddenly or did the picture fade (possibly with a pink/red color)? The problem was sudden, it probably was the inverter that drives the backlight. If it slowly faded, the backlight itself failed. Most manufacturers will recommend the entire board be replaced if it is the inverter. The inverter is simple to replace but you must get the right one for your tv. (The replacement is disconnect the wires from the old board (like molex plugs) and unscrew the board. Screw in the new board and connect all the wires.) The backlight is a bit harder since you have to use a rotary tool (Dremel) to remove the old one from the housing.

First open up the TV and remove the shielding. Look for any capacitors that are bulging or leaking. (These are cylinders on tripods.) If you see those, note the part number of the board and order a new one. Match the part number and revision if possible. Universal inverters are available but you may have issues like the contrast and brightness being reversed (press up to reduce brightness). (Depending on the inverter they range from $50-$150). You could alternatively just replace the capacitors and usually the resistor that served as a fuse for the board.

One way check the inverter is with a multimeter that can measure frequency. (You need a high frequency range ~50 kHz, Alternatively an oscilliscope can do this.) Hold the multimeter probes a fraction of an inch apart about an inch above the circuit board with the TV plugged in and on. If the inverter is bad or the frequency is too high for the multimeter, you will see a result near zero. If the multimeter gives a measurement of 1 or a value of 20-60 kHz (depending on the TV), it's probably the backlight.)

I hope this helps.

Image goes to black on Sharp flatscreen.

An LCD unit? Sounds like the backlight is failing. When it goes black next time, use a strong light next to the screen and look for a faint image on the screen....

If it is the backlight, its a service shop issue.

Sova LCD 32" with no Picture

since i do my stuff by trial and error, sometimes its just a matter of making sure you dont have a video cord plugged into an audio plug that is supposed to be for the tv signal to go out and not come in or that where you have the left/right audio plug is good, but the video plug is broke.

i just move from one slot to the next trying different a/v (out) spots
