Sounds as though there is an intermitant, heat-related problem with the HV transformer. You can order this at a tv parts shop or from Sony (probably more expensive) the part number should be on the part or on a schematic. If not, the parts dealer can look it up from the model number.
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.
do you get sound while screen does black? what do you mean by "until eventually it has turned black and will not come back"? is it black from the minute you turn the tv on untill you turn it off? if sound is good but picture is black, it may be the resault of a fried monitor tube, in this case replacement will cost alot.
if sound is dead also, them it is probobly power supply related issue. get out your DMM and measure the voltages in the power supply. When the screen goes black, is there still regulated B+ going to the circuitry? Do you still have HV? Is the filament of the CRT lit? Does the set still have a raster (you may have temporarily increase the screen setting to see it)? Do you measure any of the flyback derived B+ voltages that go to the video processing, tuner, Vertical Deflection, and other circuitry?
