Question about Sharp LC-32SB21U 32 in. LCD TV

1 Answer

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 to replace it. I set this one up and after a few minutes it went blank and the power/OPC indicator lights flash in some kind of sequence. Any clues? Please help I am frustrated!

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.

I have a Sharp TV model LC-32SB24U. I cannot access the menu screen because I lost the remote control. Is there another way I can change channels without a remote?


The Sharp LC-32SB24U has menu, input, volume up/down and channel up/down buttons on the top of the TV. When you access the Menu using the buttons on the TV, the Input button is the same as the Enter key. The volume up/down buttons map to the left and right arrows. The channel up/down buttons remain up and down. The Menu button is the closest to the power button (on the right). The volume buttons are the ones on the left.

Make sure that the input is set to TV to change channels. Then you need to program the available channels, access the Menu and navigate to Setup (left/right arrows). Press Input to enter this sub-menu. Then use the Up/Down arrows to select CH Setup. Press Input again to enter. Now you can set the channel source and let the TV scan for channels that have a strong enough OTA signal or are unencrypted cable channels. These are the top two options in the Channel Setup menu. The details are available in the manual which is available here: http://static.highspeedbackbone.net/pdf/Sharp_LC37SB24U_LC32SB24U_Manual.pdf . For OTA channels, you may need to check the signal strength under the Antenna Setup - Digital option in this Setup menu. OTA Digital signals will not be tuned in if the signal strength is low. It's an all-or-none tuning; amplifiers and external antennas may help. See tvfool.com for details of transmitters and the recommended antenna for your area. (Warning: damaged amplifiers can become filters and block the signal on some channels. Replace the amplifier if it is damaged.)

If you look to replace your original remote with a universal remote, you'll need one that was programmed more than 6 months after the TV was released. That may be 12/2005 based on the manual copyright date. Look for a remote that has a Menu and Input or Source button and check all of the codes to find one that matches all of the features on your original remote. Amazon has an OEM remote for the LC-32SB24U; remotes.com also has a replacement remote available that has been programmed for the TV. (On remotes.com, search for the LC32SB24U.)

I hope this helps.

Power light blinking no display on lc 32sb24u


Its almost always caused by bad capacitors on the power board. You can get a repair kit or the replacement power supply board from www.tvrepairworld.com

There is a blue line down the middle of my sharp lcd 32sb24u tv.


Hello; If this line is razor thin and goes fully from top to bottom, the LCD Panel is bad and costs more than a new TV. Time to shop for a new set if this is the case or just put up with the line. John

I need to receive a manual on the operation of my sharp tv


I believe your TV is a LC-32SB24U, not LC-325B24U.

My problem is that when I watch my New Flat Screen 32in Sharp TV I see lines in the back ground and I purchased this TV a month ago is there anything you can do for me?


All you can get out of this will be people watching it for an excessive time on a non-moving screen such as a weather channel.You can't do nothing unless you have a receipt, then try to take it back.

Line accross top of the screen with flashing black and white boxes


Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.
