You are simply in blackout mode. This is so at night you aren't blinded by the glow of a screen. Here are instructions right from the manual to turn on or off.

Blackout Mode On and Off
When Blackout mode is turned on, the monitor display will turn off to
reduce power consumption.
This additional power enhances the sound quality.
1 Touch [VISUAL] on the main source screen.
The VISUAL selection screen is displayed.
2 Touch [OFF].
The backlit-display portion goes out.
3 Touch [OFF] again to cancel the display backlight.
• To make the setting, set to “Setting the VISUAL Touch Button” (page
34).
• If any button on the unit is pressed during Blackout mode, the
function will be displayed for 5 seconds to show the operation before
returning to Blackout mode.

The problem is your cable box. I know you said you replaced it, but I work on TV's everyday and, sorry to say this but cable box HDMI outputs have serious issues, like no or intermittent sound and video. I have seen customers exchange their cable boxes 5 and 6 times and still have the problem. Your best bet is to use the component outputs of your cable box, visually you will not see a picture difference between component and HDMI when using a cable box. Your other solution is to get satellite; I have NEVER seen an HDMI issue with a satellite box

I had the same problem and fixed it with a new backlight inverter board. It was a pretty easy install. The part is available on eBay. http://cgi.ebay.com/New-Inverter-for-Dell-W1700-17-inch-LCD-TV_W0QQitemZ400017456720QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116

Good Day;
I would suspect U-VERSE. I had it installed recently ...had problems. They came out and changed "wires". Now okay. Please call them first. Good Luck, big IRISH.
