Hi, re-solder the vertical output IC and surrounding parts, bright line left to right in middle of screen with black above and below this line is total vertical collapse, the fact you can "smack" the tv and make it fill the screen says it`s broken solder, BMW Rider

Sansui SV2916 has a white horizontal line across the screen and there is a picture within that line. What causes the picture to be reduced to a white line?

That is called frame collapse because the picture "frame" has collapsed into a single line. The usual cause is dry joints if it went all of a sudden or capacitors if it took a while. The frame outpur IC may now have failed but not always.

I have owned an emerson tv for two years now. All of a sudden the picture has become very blurry and white. It is not the cable connection and a DVD is also white and blurry. Even the input channels are...

you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

No picture no sound

Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Intense white & coloured horizontal line on black background on startup

I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

Poor picture quality

You need to consider the following tips herein as follow:

1) Field collapse (horizontal white line on screen)
R710 dry joints. Same as C2146TN & C2546TN problem solved with thanks to Mike G & Barty. Power off/unplug. Get to circuit board underside with aerial socket up-R710 is near top and right of centre-cluster of 4 joints best resoldered
2) Picture is horizontally narrowed and deformed
Capacitor C2913 (390nF, 250V) on the deflector PCB had lost capacity

Please let me know any update
