Most of the new TV's display a blue screen when there's no signal for it to lock on. Try unplugging it for about 5-10 minutes and see if that clears up the problem. Why? Because they have microprocessors in 'em (computer chips) and just as like with any other operating system, they can hang up or crash. This isn't an uncommon problem with today's TV sets. Unplugging it for awhile resets the microprocessor (in other words, it causes it to re-boot when you plugit in again).

As I have a Logic LCD flat panel TV and there is sound but no picture and I have checked the inputs but it still doesn't work can anyone suggest how to fix this?

With an LCD flat panel TV or monitor, the most common problem is that the back light went dead. It can be either the fluorescent tube or the invertor, which is the high voltage power supply that drives the tube. It could also be the semiconductor that is the switch in the invertor that turns it on and off.You almost certainly are between a rock and a hard place. If you have to come here to ask this question (and no offense is intended or implied), you probably won't be able to do anything to repair the unit yourself. What you can do is call around to some local shops and describe the problem and see what kind of repair costs you might incur having it repaired.

Why is the single sideband suppressed carrier version of amplitude modulation is not used for the sound broadcasting and television broadcasting?

A single sideband receiver have a BFO (Beat Frequency Isolator) that is generating the other half side of the original audio. The BFO is hand tuned to clarify the audio to, as close as possible to the original sound. An automatic clarifier is not really possible therefore music and voices never sound the same as the original.
