Question about Televison & Video

1 Answer

My Sharp Aquos TV turns itself on and off. There is no picture most of the time, and the audio comes on briefly. The power light and the OPC light flash simultaneously at times. The remote only works some of the time. I spent hours last night re-checking settings and have come to the conclusion it is nothing I have done. I have heard horror stories about Sharp service and am almost afraid to call. The tv is under warranty and less than 6 mos old.

The Sharp people told us they have had 35 complaints in my area about the Cable company signal (Cablevision) screwing up these t.v.s. Seems the digital channel settings are not compatible with the signal. I tried to confirm this with the cable company and they have no plans to fix anything on their side. If I unhook and re-hook the cable, the t.v. seems to work again. This is annoying because it happens on ABC where my favorite shows are!

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.

No picture, but power is on...


How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
