Check your owners manual look for the section that tells you how to adjust the televisions features using the on screen menu.You probably Have it set on auto adjust. You must turn this feature off, to use the manual controls. If this does not help go to the Sharp website and search the frequently asked questions and troubleshooting sections. Search for your problem and similar one that may have answers. If all this fails you, call technical service and ask them for help with your problem.Hope this helps you with your problem.

LC-52SB55U Sharp flat screen tv audio only but no picture


Backlight is possible but if it is out you should be able to see that by looking from rear of set---most can be seen---if both are out (usually there are 2) it is likely the power source that fires them or a related issue.

What is opc light on my sharp aquos tv


This can be called Optical picture control and it adjust to suit the room light.

Please read the text below"

Dynamic Backlight Control - One of the nice features of the Sharp AQUOS LC-32D6U is what Sharp calls OPC, a name they use for their dynamic backlight control. You might also see this feature referred to as a dynamic iris on other LCD HDTVs or disguised under some proprietary name, but fundamentally the principle is the same. Its primary function is to try and maintain a high Full On/Off contrast measures the ratio of the light output of an all white image (full on) and the light output of an all black (full off) image. 2) ANSI contrast is measured with a pattern of 16 alternating black and white rectangles. The average light output from the white rectangles is divided by the average light output of the black rectangles to determine the ANSI contrast ratio. When comparing the contrast ratio of video devices make sure you are comparing the same type of contrast. Full On/Off contrast will always be a larger number than ANSI contrast for the same video device.">contrast ratio under any lighting condition. So when room lights come on or off or the sun enters the room, with OPC enabled, the backlight in the LCD will dim or brighten depending on the amount of light in the room. This is managed by a light sensor located on the front of the unit. When OPC is enabled there can be a slight reduction in the dynamic range of the display as the display attempts to maintain contrast and color saturation as room light changes. We had a chance to compare this feature with another LCD HDTV that was of comparable size but without dynamic backlight control, and the Sharp AQUOS LC-32D6U with OPC enabled was the clear preference.

T.V. won't allow me to adjust color and sound...


Chepe_77,

You are absolutely correct. The reason why you cannot change your audio and video settings are due to the fact that you are in "Dynamic Fixed". Which is one of your many av modes. Av modes are different preset color settings and dynamic fixed is the only one that will lock your settings. Best Buy set it that way so that people could not just come by and alter the settings on the unit. AV modes are on all sharp lcd products and even though you have the wrong remote you should have an av mode button on the remote that came with it. Try pressing the av mode button and see what happens. When you press the av mode button, you will see your av modes change at the bottom of the screen. However, the issue still remains that you have the wrong remote. So there is a chance that you may press the av mode button on the remote that you have, but it still will may not work ONLY because you have the wrong remote. If the remote you have does not work, I GUARANTEE that pressing the av mode button on the proper remote will take care of that. If you dont want to purchase the remote from sharp, www.partstore.com is a good place. Good luck to you

Blinking green power light


All,

I had the same issue after one month of use. A repair cie came and fixed the problem. It appenned to a neon connector that wasn't properly plugged in the TV.
The Technician explained to me that m TV had 16 neons and a sort of controler for those. Often - from factory - a cable is not sitting properly in its position...

Since I have no problem.

Well, there is a way to have the clearest possable picture. Get HD cable TV box that is HDMI compatable and watch only HD channels. Or buy a blu-ray player, hook it up via HDMI and only watch blu-ray disc in 1080p!
