Question about Sharp 25L-S100 25" TV

BLack box in the middle of my screen?

When you turn on the TV, the picture is good for 3-5 seconds. Then a Black box appears and covers the middle of the tv on down. If you change the channel, turn up the volume, go to the menu, etc. it clears up and then black box reappears. Is there a way I can fix this without taking it somewhere? Thanks, Harry

Iv'e run into this before, you have closed caption text 1,2,3 or 4 on. this is different than the normal "cc" cation. just go into your menu & turn off closed caption.

Black Box on the screen

It sounds like a text box that isn't receiving any text. If it covers almost the entire screen, then you might have accidentally got the settings into DEMO mode. It could also be a box for closed captioning, but that usually covers just the lower part of the screen. Either way, the solution is to go into the setup menu and restore facotry presets.

Black screen

I work at at a school, and we had the same problem. Turns out, it a Closed Captioning problem.

We found the manual, and it states that "If a large black box covers 80% of your screen, the Text mode is probably set. Press 'Closed Caption' to turn it off." The "Closed Caption" button is on the remote. If you don't have the remote (as in our case), you can go to "Closed Caption" in the menu, and pick something like C4 and T4. That stopped the black box for us.

Black box in the middle of the screen

The closed caption is turned on. I don't have the schematic in front of me, so, I will wing it. There may be a button on the remote that says CC, if so then use that button to turn it off, if not then go to the service menu and you may have to search a bit. Either way it's an easy fix and you can do it yourself. If you can't find it, then, reply and I will give better instructions when I get into my shop next week.
