Black growing on screen

We are getting black on the screen and it grows from the right side and moves across the screen. If we tap the side of the tv it goes away for a little bit.

That is normally cold solder joints around the High Voltage transformer ( IFT) and also the video section. It should'nt be a major repair for a tech.

Can you post picture? From my experience, it's the moisture that gets in between the panel and not much you can do but complete disassemble of the panel to clean it out.

BLACK GAP ON RIGHT SIDE OF TV SCREEN


This is a sign of an aging horizontal deflection circuit. Go through your initial setup menu and see if the set gives you the option to adjust 'width.' This may have enough range to stretch the video to the edge but it will also affect the geometry of the displayed video.
As of now, the component most likely growing old is an electrolytic capacitor in the horizontal circuit that has lost value. It is usually a bipolar capacitor in the range of 4.7 - 33 uFd. It will likely continue and become more annoying and if you look closely, you can probably see that the geometry of the picture on that side is not as it should be; it will often appear 'squashed' together.
Allowing it to just grow may result in the failure of the flyback (a high voltage transformer) and/or the main power transistor that drives it.

36" CRT Toshiba has that vertical issue mentioned on here a bit


Your problem is most likely caused by a cold solder joint in the vertical circuit. Normally this is easy to find and correct. The problem will only get worse over time, but not likely for more damage to occur.
