Input screen (HDMI1-2-3, etc) has HDMI2 & 3 "greyed out." How can I reset?

Try resetting the color in the TV menu. Also a loose or damaged wire and cable can distort the TV picture. Check the cable that you are using for that input and be sure it is not damaged or loose. You can also unplug the TV for 10 minutes and see if that resets the issue

Assuming it's not your device causing the grey lines, just change your aspect ratio settings. Each input has a different set of settings that you can change, so don't worry about messing up the settings on your HMDI 1 input for example if you change your AV1.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Try to see first if you have the latest iTunes installed on your computer. If you already have it installed, try to click Store in the left side of iTunes and login in again to your daughter's iTunes account and see if iTunes will turn grey again. If you can login to your daughter's iTunes account and she can see her transactions, account profile, etc., then the account is active and the reason for the grey out screen is because of your iTunes version. If you cannot login, you can try to access the link below to have your account password reset to be able to access it.

If it says that you're account has been disabled and you cannot reset your password, your only option is to call Apple and ask them to be able to access your account again.

service menu procedure text changed by midge to work with Sharp LC-32P70E & probably the same for similar models.

There are probably ways of really messing up your set if you do the wrong thing from the service menus, so do this at your own risk:

To enter service menu, make sure the set is plugged in but turned off at the power button on the top of the tv,
then while holding both input button and volume down button, push the power button. Within about 5 seconds, the set will power up keep holding the input and volume down buttons until a small "K" appears in a box on the left side of the screen. Then press and hold the channel down and vol down buttons at the same time to enter the service menu.

Once the service menu is displayed on the screen, you can get the screen to display different levels of solid grey by pressing the number keys on your remote. i.e. press "1" to get a relatively dark grey, 2 for a lighter grey, and so on up to 6 which is a bright white screen; 7, 8, and 9 don't appear to do anything. (this was for adjusting grey levels, other settings are available too) Press any number a second time to return to the service menu...

Not sure wether the grey background settings apply, but for entering the service menu it does.

I think to get out of service mode you have to disconnect the TV from the mains and wait about 30 seconds.

it's some time since I used the service menu on the Sharp Aquos but I do remember you can do a full reset to factory settings as well as turn on, off and reset certain system settings too you will just have to experiment with the remote keys, I think the colour fastext key access different menu levels etc but as I said I am unsure, at least this procedure will get you there so you can try for yourself.

Hope this helps

Please come back to let me know if the service menu procedure works for you.

Good Luck

Midge.

- Press Menu
- Press 991
- Go down to Memory recall and press enter
- It will ask you "ARE YOU SURE"?
- Select "Yes" and press enter
- It will take you back the menu screen, turn off the TV and turn it back on

Your OS is courrepted. Try reinstalling the OS choosing arcive install.Issue will get solved

Is it this way no matter what input you are on? Try switching to each input and then going into the menu to see if it is still greyed out each time? If it stays greyed out, then you have a bad main board.

Try the reset on the remote. Press this key twice to restore factory settings. The TV will automatically start Channel Search and clear all customized settings. These features will automatically reset: ? Picture/Sound Adjustments: Color, Tint, Contrast, Brightness, Sharpness, Color Enhancer, Tone, and Surround Sound ? Channel Memory ? Audio to Stereo ? Caption to OFF ? V-Guide to OFF ? Aspect Ratio to 4:3 (normal) ? Menu Language to English ? Sleep Timer (if previously set) ? Video to TV (if previously set) If desired, personal settings can be made again using the menu options

Clean , outside of lens, go to menu reset to factory defaults, try another new battery, take out memory card and wipe lightly with alcohol. If none of this works contact or call customer support for brand. You may have dead pixels, if that is the case it's time to buy a new camera. Jimmy
