Customer Question

Hello, I have a LC-40LB480U model 40" LED and it is hooked up to my PC via HDMI. I was wondering why I cannot adjust the tint, color, sharpness, active back light, noise reduction or active contrast as they are grayed out?
JA: What's the exact make and model of your television? And have you done any troubleshooting yourself?
Customer: Sharp model= LC-40LB480U
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?
Customer: I can adjust on the TV input but not on any of the HDMI's
JA: How long has this been an issue? What happened right before this popped up?
Customer: I just purchased this TV less than 2 weeks ago it was that way out of the box
JA: Anything else you want the TV expert to know before I connect you?
Customer: these are my only questions t.y.

If those options are greyed out then you may be using a preset mode.

Try selecting CUSTOM picture... you should then have full access to the settings like Brightness, Contrast, Color and Tint.
