Those are the symptoms when the power supply is giving up.
Unfortunately there are not many replacement service parts around to swap the power supply assembly, but It will need to be fix to the component level instead.
I service these power supplies.
Let me know if you need more assistance.

LCD screen gone dark, can still hear sound and see image


It wouls appear one of the backlights in the screen is cutting out, this will require the screen to be replaced although in certain circumstances, depending on the age & model of your TV, it is sometimes possible to change the faulty backlight independantly. Take it to a repair centre to get an anaylisis of the type of screen it has.

Top half of screen is darker than bottom half


The problem is most likley the TV backlight - it is very unlikley to be the graphics card or video input or any other circuitry within the TV.
Also, the problem can be manifested by flashing or flickering of one or both halves of the screen, and sometimes it is a left/right split rather than a top/bottom split, depending on where the lights are positioned. Before failure, you sometimes hear a very high frequency buzz for a few weeks before it fails - the frequency can't be heard by most adults as it ranges from 15kHz-25kHz, but children\animals can usually hear it.
Generally you will need to replace the backlight tube or the invertor that drives it. Generally you can identify the backlights as thin glass tubes buried deep within the panel itself usually with one wire going to each end of them - they are very fragile. The invertor is connected to the backlight tube and looks like a circuit board, often containing a high voltage warning. Usually there are two or four conductors connecting the invertor to the tubes, which can be identified as thicker individual wires as opposed to the flat ribbon wire used for data for the actual image displayed on the screen.
On some screens you may be able to unplug\swap one or both tubes to identify if it's the tube or inverter.

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.
