top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.

If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit

Top half of screen blacks out


Today, after speaking to the Sansui Manufacturer representative from Japan. He stated that all you need to do is to turn off the closed caption from the TV remote and not the DVR remote. Black screen can occur at the top half or the bottom half of the screen depending on how it was originally setup during installation. Try this and hopefully this fixes the problem.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
