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.

We can hear it but the picture is very narrow in the middle if the screen


If you are referring to a horizontal line or bar, you will have to resolder the vertical IC. You may also need to replace the electrolytic capacitors that are almost next to the same IC. Now if you have a black vertical bars on the left and to the right side of the screen, you have a horizontal problem. Bad electrolytic capacitors and bad resistors in the horizontal deflection area of the TV board! Thanks for asking and give me a few hands of support!

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
