Based on the symptoms you described for your Hisense model 50h5c TV, it seems that there may be a hardware issue affecting the display. Without being able to diagnose the TV in person, it is challenging to pinpoint the exact parts that may need replacement. However, there are a few components that commonly contribute to display issues:
T-Con Board: The T-Con (Timing Control) board controls the timing and signals sent to the display panel. If there are issues with half of the screen or black screen with half lines, a malfunctioning T-Con board could be a potential culprit.
Display Panel: The display panel itself could be defective, causing the black screen or half-line issue. Unfortunately, replacing the display panel can be costly and often not cost-effective compared to purchasing a new TV.
Main Board: The main board handles various functions of the TV, including signal processing and overall control. In some cases, issues with the main board can cause display problems.
Try connecting to an external monitor if display screen is only showing half of my desktop, the other half goes black or flickershalf of my desktop, the other half goes black or flickers various colors then it is the video card if not....have ur display screen changed.
Have several problems with either a bad LVDS cable from Main unit to the LCD controll bd. Sometimes the cable is just not connected properly. If you reseat this cable and the problem still exists you most likely have a bad LCD control bd.
if it is just half of the screen and the rest is black- you need a new screen. If it is half the screen all squished together (you can see the whole desktop) you need to reload the video driver
