check the aspect ratio on the dvd player and the tv both should be set the same

wish the news was better for you, the convergence chip or the color engine has faulted and burned the screen This will be an expensive repair unless it has extended warranty

Follow the instructions and pictures in the manual OR if cable the company will usually come out and hook it up.

Try changing the INPUT by pressing the button on remote control. Try plugging something else into tv. Ex, dvd player. And try that input also.

You don't. You can download just the manual from here.

yes after to the fuse you must have a reading of 120vac if none the fuse get busted. if the 120v is present then it will goes through the rectifier bridge diode and primary capacitor of the power supply board to have an stand by voltage at the power supply board. when you press the power button it will send signal voltage coming from the main board to turn on the power supply board. the you will need to get an output voltage at the power supply board of 5v dc, 12v-16vdc and 24v to turn on the all the circuit, the main board sound amplifier and the inverter board for screen back light.if you can get those supply the tv unit will not turn on.
