You have selected an input on the display that is not getting any signal that the display can recognize. Press the source button either on the set or on the remote until you get a signal.

Your TV has a bad panel. Your Panel needs replaced. Would be more cost effective to replace the TV.

Not a great brand, generally when out of warranty, you are on your own. No repair except by independant shops if they will even touch it - no manuals or parts that they can get... Considered a disposable set.

Looking is one thing and testing is another. You will have to check for the 5 volt standby on the power supply then check for activity from the micro to turn the power on to the run state.

I went over the Manual for your TV, Sadly, it doesn't have a port for headset. It only has one audio output port for the stereo system call Digital audio out. The port on the back of the TV has a one for the size of a headset jack. But, it's only for the PC audio in port.

I wish there was some other way to hook up the headset for your son. But, the only option I see is to take the TV back and get one that has the headset port.
Sorry I couldn't help you out more. :(

Whoever told you that is an idiot.

After June 12, try rescanning channels, some of the stations changed their frequencies.

It is a 720p, 1080i DTV.

If you get a blank LCD, dimly lightened by a whitish back light, then the LCD display eis either faulty, badly connected, or the ribbon connector to LCD is defective.
The camera must be taken apart, ribbon cable tested, and eventually replaced and adjusted.
If all contacts on ribbon cable return continuity (cable is fine), then LCD is faulty, and must be replaced.
Althought the job is not too difficult, an user without experience may damage the camera in attempting this repair.
My first suggestion is always taking the unit to a camera shop.
