Sharp aquos getting only audio and blue screen for video :( i have done all troubleshooting steps and now just want to buy the board needed. all caps are looking ok tried the reset. tv just turns itself on when i plug it in dont have the remote so no clue if menu shows up. backlight apears to be working and when i hook up xbox 360 i can hear it boot and see the screen get brighter (not much) thanks for your help

SOURCE: images go suddenly darker

Turn off the the OPC feature in the Menu. If that doesnt help, what youre seeing is most likely the Advanced Dynamic Contrast going to work. In layman's terms, it automatically adjusts the contrast depending on the video signal it is receiving. If you want to disable this, change the AV settings to "User" (button underneath the bottom door on the sharp remote)

SOURCE: Aquos screen blacks out with xbox 360 using Component Cables

Downloaded the updated firmware from the sharp website to a usb drive. Placed the drive in the TV and went to the update software option on the TV menu. Since the update, I no longer get the black-outs on the screen. I also put the resolution on the 360 back up to 1080p and it works great, even through the component cables.

This may help, but at your own peril.

SOURCE: how do i hook up

You have a few options actually. depending on which 360 you have you have at least 3 ways to connect; 4 if you have CDMI cable output on Elite 360. you only need to pick one though. easiest is the plug with one yellow and a red and white. the yellow is the video and the red and white are the left and right audio. You can use the red green blue plugs choice if your tv has that input. in that case the red green blue are the video and you use the other paired red white for audio. You can use the S video connection (the round one that looks like a mouse plug) for video. You can use the HDMI (flat, looks like giant USB slot) for really high quality video. So, basically just use whatever cable you happen to have. If you still have questions, please ask as we will definitely get you hooked up for sure:) farmerbear at FixYa

I'm not certain of the specific model number of your set, but this should be the same for all Sharp Aquos models.

First, navigate to TV input, and select menu
Next, enter setup and select, "ez setup"
In the ez setup menu, select "home", not "store", for television location.

This should turn off the demo mode and solve your issue.
