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.

SOURCE: Remote function on LC-32SB21U stopped

Hi,

This is a common problem with Sharp LCD models. This seems to be a faulty IR circuit. A simple solution that sharp gave to their customers - unplug the TV for few minutes, say 15 minutes and then plug it in. Most of the times it would work.This is more of a design fault as there is a problem with IR circuit that somehow freezes and needs a reboot. They have certain upgraded firmwares for the same. It could be due to faulty IR sensor ( though rare possibility ).Unfortunately, this is not a DIY and you need to call Sharp.

Note - This is a common problem and Sharp is aware. Calling a local tech would not help as this has to be taken care ONLY by Sharp.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

SOURCE: sharp tv difficulty starting. Will

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!

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

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.
