Re: Turned on set....screen all black except a dark blue...
That message is presented when a selected digital channel is too weak to decode. Let us hope that something was accidentally changed:
Is the channel legitimate? Is the antenna/cable still connected (to the Digital input)? Go into menu - setup - channel setup. Is the selection of either cable or air channels correct for your situation? Use menu - setup - Antenna Setup-DIGITAL to examine the signal strength. Is there nothing at all, or is it just a question of strength?
Odds favor a change in channel setup that you would not have made intentionally, or a simple physical problem (input cable, etc.). Start from scratch, and check the settings and connections you originally made. Hopefully it will be simple and cheap!

The dark rectangle appears because you have the closed captions on and set to TEXT. Closed captions set to CC1 puts the words on the screen and TEXT puts a black box on the screen. Go into the menu, navigate to the page with closed captions and set your captions to OFF.
Try just changing the channel to the one set up to receive broadcasts. That worked for me-- the TV was working great until I pressed Input and for some reason that changed the channel away from channel 60, which is the one programmed to receive broadcasts from Dish Network. When I entered 60, the message went away and I got my programming back.
U just take ur tv original remote just turn to channel 3?Why is ur cable service connected to channel 3?The proper way to connect to cable service is get the pay cable connected.Take ur original tv remote.Push Menu on ur remote,go to SET UP go down the CH Setup,pick cable,than scan for all the pay cables channels you pay for.
If it is a large black rectangle that blots out the middle of the screen then you need to check your CC (closed caption) setting. Make sure the closed caption is turned off. I'm not up to date on the newer sets, but a lot of the older ones had more than one CC setting. One setting ran the captioning across the bottom, another put it in a big black box in the center of the screen. Most places didn't support the full text so all that showed was a big black rectangle on the screen. Since I'm not sure exactly what your rectangle looks like, this is my best estimate of your problem. Hope this helps.
