Samsung 940MW monitor will not cut on. Green LED flashes only


Answers :

Most likely it is a set of bad caps on the power board. If you are okay at soldering to do the following with the unit unplugged:\015\012
\015\012Remove the back cover:\015\012\015\012
    \015\012
  • Remove the 4 screws that supports the stand and slide it out the bottom.
  • \015\012
  • Remove the 3 screws along the bottom of the back plate
  • \015\012
  • Use a small flat blade screwdriver or plastic wedge (less risk of damage with wedge) to press on the release tabs around the sides.
  • \015\012
  • When removing the cover make note of the antennae connection since you will have to work around this
\015\012
\015\012Remove metal cover over circuit boards:\015\012\015\012
    \015\012
  • Remove 8 (if I remember correctly)screws securing the metal case. Do not remove the screws securing the LCD panel to the frame
\015\012
\015\012Inspect the power board:\015\012\015\012
    \015\012
  • Look towards the top of the board for capacitors that have a bulge or brown "gunk" on them. If you have some that are this way this is most likely the problem.
\015\012Here's a picture of 4 bad caps on a 940mw. Once I replaced the caps the panel works great and had the same issue as yours.\015\012
