A TechLore "Ask the Experts" Question...
Question:
I just purchased a new Sharp Aquos LC-26D5U TV, and I have Comcast digital cable with a Motorola set-top box. I have the cable box connected to component inputs on my TV, but the HD channels are only showing in SD. How do I get my HD channels to show up in HD? Do I need a wiring diagram?

Answer:
As long as the Motorola HD cable box is connected to the television's component video input (red, green, blue colored jacks), then the box is properly connected to the display. You have no need for a wiring diagram. Just make sure that you have the television switched to the appropriate input when you wish to view your HD cable box.
You may want to check the main configuration menu of the Motorola HD box. While the unit is off, press the MENU button on the remote control. A setup screen like the one pictured above will appear. Check the setting next to the YPbPr Output. If the current setting is 480i or 480p, HD programs are scaled in resolution when displayed. Set to 720p or 1080i, and HD shows will no longer be scaled.
You must also consider that not all HD channels will be broadcasting HD materials at all times. HD programs on most major networks are run during prime-time hours, and only those shows produced in HD can be broadcast that way. Otherwise, the analog versions are upconverted and broadcast on their digital channels, but will typically won't look any better than the analog feed. Check your local listings for HD shows.
