Having problems with your Samsung SyncMaster 940T 19" LCD Monitor ?

Power light comes on but no picture - Samsung SyncMaster 940T 19" LCD Monitor


Answers :

Try to check if the monitor displays anything - it would be very dark so experiment with angles/lighting. If you see picture it means that backlight is broken. Broken backlight can be caused by:
\015\012
    \015\012
  1. Burnt "bulbs" (cathodes or LEDs) - If this is an LED backlit display then this scenario is highly unlikely.
  2. \015\012
  3. Broken inverter (most likely)
In both cases you need to have it repaired by a technician. If this is a relatively new display this will be cheaper than buying a new one.

I can't turn it on or off anymore, as soon as I plug it in it beeps and blinks and is completely unresponsive. The backlight and everything else was working flawlessl
