The solution was so easy and the cause so ubiquitous that I really am surprised, with all the talent and experience that exists here, nobody twigged on it. [Edit: Well, now I see that videobruce did
twig on it; but I didn't understand what he was telling me. Thanks, videobruce. Sorry I was such a lamebrain!]
Yesterday afternoon, as I was driving near the dealer's location, I stopped in to see if I could get someone to tell me what was happening, how bad it was, and what it would take to fix it -- sort of like asking a doctor at church whether he thinks you have cancer!
The service writer did not have a clue, and the TV tech was gone for the day, but the service writer suggested I talk to one of the two salesmen who sell TV because (as I already knew) they were both very
knowledgable. I waited until my salesman was finished with a customer and began to tell him of my gray rectangle.
I didn't get very far into my story before he said, "Oh! That's closed captioning in 'Text' mode. Just go to the Menu, select Captions and turn off captions for analog channels."
"But," I said, "there are no captions!"
"Right." he replied. "That's because you have to arrange with your cable company to receive the text captions, so the place where the captions would be is blank. You can make the background gray or black, but there won't be anything in it unless your cable company sends it to you."
"You're kidding!" I said.
"Nope. Turn off text captions; that will fix it. Guaranteed!"
Well, I don't have to tell you the rest (but I will). Sure enough, captions for analog stations was on "Text 1" (there are four levels) and the background was set to gray. The more usual captions that dance around near the bottom of the screen in taverns and some doctors' offices are CC1, CC2, etc. Those captions are visible if the program contains them without intervention by the cable company.
Interestingly, the settings are independently selected for analog signals and for digital signals, so that is why I was getting the problem only on analog channels. Whichever of our household gremlins had turned the captions on had done it only for analog signals. And the gremlin (probably yours truly
) had been tuned to a digital channel and saw no change and just left things that way.
My wife (aren't wives just darling?) pointed out the warning on page 66 of the Mitsubishi Owner's Guide which says:
So, as Bugs Bunny always, said, "That's all, folks!"

Recently I have been plagued by a gray rectangle covering most of the viewing area of analog channels. I can't say for sure it never happens on a digital channel, but what testing I have done suggests it is on analog only. I have begun to do the following:
When the rectangle appears, I can press Menu 2-4-7-0 and look for digital signal strength. It has always been N/A (so far). By the way, as soon as I press "Menu," the rectangle disappears and if I could stand to watch the picture through the info screen, that would be a plan because the rectangle does not appear as long as the info is displayed. As soon as I hit "Exit," the rectangle returns as before.
When changing channels, the rectangle disappears momentarily and the new channel appears normal for a few seconds before the rectangle reappears.
The rectangle appears to have an aspect ratio of 4:3 but it does not cover the vertical area completely -- I'd say about 80%. The picture is visible through the rectangle, but the density of the gray is rather high. The areas around the rectangle appear normal.
I have a cable card and a DVR/Tuner. Last night, the TV was set to the DVR/Tuner and we watched for hours without any rectangle appearance. Today, I tuned to an analog channel using the cable card, got the gray rectangle, and now switching to the DVR/Tuner does not remove the rectangle which appears even when the DVR is tuned to digital channels.
I purchased the set from an independent dealer of long standing in our community (50+ years) who has a good service department. But, when I call them, they will send a truck to take the set to the shop, and I will have to pay some minimum amount just to get that far. Before I do that, I'd like to know if anyone who has seen it would tell me what might be causing it.
Is there anything I have failed to disclose that would be helpful?
Thanks in advance for any ideas.
