How to change aspect ratio on sharp tv?

You cant change the aspect ratio. You can stretch and zoom programs . Some programs like movies are in letterbox and you can stretch to fill the screen, but the results are not perfect. Circles will be oval and you will cut off some of the viewable picture. This is normal

Sharp tv difficulty starting. Will come on and immediately go off .Audio stays on screen black. this happens over and over. Banging on the on/off button works sometime. Once on it stays on indefinately....

I have not worked on this particular model. But, I wopuld certainly say you have a couple of bad capacitors in the power supply. You will need to remove the back cover. Weak or bad capacitors will cause your TV to do exactly what you describe. You may note these capacitors will be bulged. The values may or could be 35 volts at 1000Mfs. Once again, I do not know the exact values. In most cases these capacitors in many other brands will have this value. This info is a very good start for repairs. Hope this will clue you into a repair. Thanks for asking and show all hands of support!

I have a Sharp AQUOS LC-32D47UA 32", black box

Press the cc button on your remote control. You want cc to be off. Play around with the cc button to become comfortable. Press it over and over again. Observed that a different closed captioning option appears on your screen each time you press the cc button. Now press cc and when it says cc off do not press the button anymore.

Sharp LC-32SB21U Opc and Power Light Flash

It sounds like you have some capacitors that have gone bad or changed value. The place to look is in the power supply boards. Notice the top of the caps have an indented X or V which is really a vent. If the cap over heats it will bubble out a brown residue on top of the cap. The top of the cap is supposed to be flat, if it's not flat but has a dome, replace it. You have to take the caps out of circuit to properly check them with a capacitance meter. Also bad solder joints on the power supply boards will give you these symptoms. Hair line cracks in solder will separate when cold but will expand and connect when warm. That's why it may start working after it's on for awhile.

I originally purchased a LC-32SB24U and wound up needing a replacement because there was a black line going accross the top of the screen. Sharp didn't have any of that model so they sent me a LC-32SB21U...

Don't feel bad. You didn't do anything wrong.
They sent you a TV with a bad power supply board for the
screen. The TV is trying to power up the screen, but it can't. Because of a defective part somewhere on the power inverter board for the screen. That is why the power/opc light is flashing.

I would call them back and and make them replace the TV.

Cracked L.C.D. screen

My first guess would be no since the model numbers indicate that the screen sizes are different (32 vs 37). The final determination is best made by checking the part numbers or verifying compatibility with Sharp directly.
