How do I get my LED TV to start working?


depending on the model, if the backlight has come on but nothing else then the main av board has fun into a fault, some models have a rest sequence to use on the original tv remote to reset to factory settings, if your model does not have this feature, then turn the power off for 10 min and plug power on and holding down the either of these, power button or menu and select. some times these work to reboot.

Remove screensaver from TV


Hello

You are refering about energy saving function I thinks. To energise this function, surf through its menu and come towards energy saver.

This power saving feature reduces the backlight

brightness level. The options are:

OFF-the feature is off and the power consumption

is normal.

LOW-power saving level is low and the backlight

brightness level is lower than normal.

HIGH-power saving level is high and the backlight

brightness is set to the lowest level.

1 Use the CURSOR Up or Down keys to highlight

Energy Saver. Press ENTER.

2 Use the CURSOR Up or Down keys to select Off, Low,
or High.

NOTE:The Energy Saver settings level varies with
the Picture / Sound mode.
OK.

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.

Picture goes dark on different sections of screen intermitently then its ok for a while


Intermittent backlight lamps or backlight inverters.

If this model has an auto-dimming feature, try disabling that feature.

    2. Highlight [Backlight Auto-Off] and press the icn_btnx_color.gif button.

Backlight only comes on when the power button is pushed


It doesn't sound like you're doing anything wrong. It sounds like that is the way the unit was designed. It's a power save feature.

Can you see the time on the screen if the room light is on? If not, the backlight won't do you any good anyway.

Unless there is some sort of menu that allows you to change it, you're probbaly stuck with the way it is. It's all in the software thats programmed into the microprocessor and that's almost impossible to modify.

The only thing I could think of is to find the backlight voltage line and power it directly off of the power supply (using isolation diodes), keeping it on all the time. This however requires you to take the unit apart and dive into the electronics - something you may not wish to do.
