Sharp 37'LCD missing Close Caption in Component and HDMI input

This set MAY require or have available a software upgrade for this issue.

Contact Sharp to see if they have it or if this is an issue in their database that is common.

If the closed caption is shaded out in the menu, this usually means closed caption is not an option. Closed caption can not be turned on if the TV is on component, RGB, DVI, Or HDMI inputs. The closed caption will need to be turned on by using the set-top box or other device that is connected to TV inputs. or if the tv is connected directly to the cable line or anteanna

go into your cutomer menu and trun off close caption

The TV will not display closed caption with HDMI input. It must either over-the-air (antenna) or composite input for the TV to manage CC.

To get CC with HDMI from your Comcast DVR, you need to configure the cable box. Instructions can be found here:

If you want CC all of the time, this works well. But since you must power-off the cable box to change the setting, switching CC on and off is a real pain.

Your set-up is similar to mine (Sharp Aquos 46" and Comcast DVR). I have the composite output from the cable box going to a DVD-recorder and on to the TV. Whenever I need CC (usually to catch some mumbled dialog), I just rewind the DVR, and switch the TV input to the composite input. Then I switch back to HDMI to continue watching in HD.

i have had to replace the hdmi input board on these units to fix them.

I have a Sharp Aquos 46" and go a Comcast HD receiver as well, and had the same problem turning off the Closed Captioning. I order to turn it off you need to go into the box user setting by (starting w/ the cable box and tv on) pressing the power button for the cable box then the menu button for the cable box. This will open up the user settings menu. Just toggle CLOSED CAPTION to DISABLED.

check to make sure they are not on auto

Give more info. In tuner mode, in component,rca or s-video input?

The hdmi inputs on this unit go directly thru the main digital pcb. and the component inputs feed thru the av pcb then to the main pcb. If the composit hook up do not work and hdmi inputs do work the unit has a bad AV pcb.
