Sansui picture fault

Usualy a problem with the LCD screen itself, that takes replacing the whole screen to fix. Sorry.

Could also be an internal connector that has gone bad. There are tiny transistors on most displays that control whole rows and columns. It sounds like one went bad, causing a dead, or constant on, column. Unless you are REALLY handy, it will probably need to go to a service center for repair, which could be very expensive.

Try flexing your screen - wrap a non-fibrous cloth around your
hand and squeeze the screen lightly all around the edge. If you
find a point where squeezing the screen makes things better or
worse, explore that point further. Squeeze just hard enough to
make a white area go light grey or yellow. It's safe to squeeze
gently with something fluffy when the computer is turned-on.

Could be a cable problem - either the cable is not making
a good connection at one end, or the cable itself may have
been crushed and one of the lines in it broken. Replacing the
cable is far cheaper than replacing the display.


Good luck
