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

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.
Manual switch ok but remote not fundtion sharo tv
Be assured that fault does not lie with the remote handset itself. In that case repair or replace it.Remote control system has two parts. One is the remote hand set and the other lies within the TV or other device for which remote controller is being used. The hand set transmits commands in shape of singnals of particular frequency and pulses per second depending on the key pressed. The other part of the remote system lying within the TV receives, decodes and responds according to the commands received in shape of signals of particular frequency and pulses of paricular width and sequence. The remote controller uses invisible infra red light as the carrier of the signal. As the light moves in straight path, no obstacles should block straight line of sight path between the remote hand set (the transmitter) and IR sensor window (part of the receiver). Hence remove the blockage from the front side of the TV.Check if the IR sensor is not defective. Check if the associated circuit and components inside the TV are not defective.Check if the TV has any switch for selecting only manual mode and locking the remote mode.Hope, some sytematic exercise will bear the successful result.

there is no back light check the inverter or resistor near the inverter
sometimes its open or change of value
Sharp LC-32SH130K always goes back to same Channel
go to the menu option and restart your TV settings to the factory settings. If you event can not use the menu and same thing happens, there is something wrong with the remote; maybe a button is being pressed all the time or there is some conductive material stick to the electric board.
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!!
Sony won't turn on
Hi,Please let me know the exact model no. of your TV to accurately diagnose where the fault came from. Also, please check what is the status of the LED at the front panel, does it has a steady, blinking light, if blinking, please count how many times it will flash. Some of the blinking LED denoting an error code.Jdvillanueva
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!
The remotes for the tv
Check to make sure the batteries are installed correctly or replace the batteries.
Also make sure nothing is blocking the view from the remote to the tv.
