Check your closed-caption settings and make sure they are turned off (or set to "caption 1" or "CC1" if you really want them). You will find the captions set for "text" now and that's why you see that black box sometimes. The set is blanking out a part of the screen for the text that never shows up. Most TVs have a single button to set captioning, so it's easy to press it and change modes without knowing it.

Please take a moment to rate this solution if it's cleared up your screen, and thanks for asking here!

Toshiba 57H83 and no longer get any sound. Any


Most often No Sound with Toshiba 57H83 is:

1. TV has a Sound on-off switch on the input panel at the rear of the TV. Very hard to see, black on black. Used to turn off speakers if you use a separate or external sound system for speakers. Usually gets moved while connecting hd cables or dusting and vacuuming in cramped space at the rear of the TV.

2. Someone accidentally changed Sound settings with remote to CC (closed caption) or SAP. Turn off in sound menu and save preference.

3. Sound input plugs from external cable or sat box unhooked or wrong input.

Toshiba 57H83 no sound fault is not common. If you still have no sound, get local service.

Or troubleshoot yourself to determine if Tuner, IF, processing, sound demod, switching or sound output circuit is smoked. Then make an installation plan.

My tv made a pop sound and went black. i can still hear sound and change channels but just no pic. it will also turn itself off after about a minute, then turn back on and so forth. got any suggestions?


Sorry to tell you that one of your tubes went. There is a projector bulb and that is probably what went. Is is still under warranty? Check out this link below for a PDF detailed manual for your item Check out pages 59 and 60 for warranty information. The second link is for Toshiba support page. Just copy and paste link into your browser.

Toshiba 57" HDTV no red in picture


I had the 65" version of that TV. Loved it, unfortunately it went bad as well. It sounds like the red tube went bad. The tube itself might sell for $400 plus. The installation will take several hours with the alignments which will need to be done. Then after all that you will start to have to worry about the other tubes starting to deteriorate. If there is any red in the picture then the tube is most likely the problem. At tat point I would say buy a new TV. The best bang for the buck if you want size and have the space for it would be the new Samsung or Mitsubishi DLP's. I just installed one at customers house. The 60" Mitsubishi is 1400 at Best Buy Good Luck Rob
