SHARP LC-32SB24U. AV MODE KEEPS GOING BACK TO DYNAMIC FIXED .

Use the input selector to change back to TV. Usually the first input on the list.

Try cycling through all of the av modes by pressing the av mode button on your remote to see if you like movie or standard. You are most likely in av mode dynamic fixed at the moment.

If the colors do not change when pressing the av mode button and selecting dynamic fixed then there is either a problem with the component cables you are using (most likely), a problem with your set top box or a problem with the television. I recommend trying another set of cables first. Try all of the television's inputs and connect different devices to it.

Go in the tv menu,right at bat u in the Picture mode go down the menu to reset push it.The Tuner board will reset it self.It will be set on the Dynantic fixed mode.And the AV mode button on the remote should able to changes back and fourth again Dynamic fix mode,Dynamic mode,Standard mode,User mode,Game mode.Not able to changes by pushing the remote button AV mode to changes,than ur Tuner board have problems,not working properly.

Unplu the TV from the wall, wait for 30 sec. plug it back in.

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

On your remote, click on "AV Mode." Then change the setting from "dynamic fixed" to any of the other options (you'll probably want dynamic, which is the next option). Then click on "menu." Then you should be able to adjust the video and the audio.

I'm happy with:

backlight +16
contrast +40
brightness +1
colour -13
tint 0
shaprness +2

although I found this setup but haven't tried it yet

backlight +5
contrast +24
brightness -7
colour +50 (review I found didn't say + or -. Try both
tint 0
sharpness -5
