The blinking green light may be indicating power supply failure

    @Tom Chichester I replaced the main power supply board and still have the same problem. Could it be the sub power supply board?

Sounds like T'Con board fault. Contact any service technician. When video signal interfaces, it goes overloaded. If you wish to get some details; check the site linked here. Pull up older posts.

Samsung 403T no power


1) Fuse is good?
2) You must have 5vdc stanby voltage the minute you plug the set into the wall, this is a must have before going further. Please look for that first, then report back what you find. Pictures and Sch will be a great help. See example of my pictures here: http://s807.photobucket.com/home/budm/allalbums

Monitor will not turn on and the green light just flashes


There's an internal hardware electronic part/s of your samsung syncmaster 930 that is cold soldered / defective. I suggest to bring the unit to an authorized service center to fix the problem. regards

Samsung 403T 40'' monitor has no power. (CK40PSNB)


FYI, I have found the real solution for this issue with Samsung 403T. It is a design flaw which leads to this problem after a while. Luckily, it can be easily corrected, but it requires medium soldering/electronics skills.

Anybody interested in how to fix it feel free to email me and I'll provide you with the solution. Please make sure that the symptoms of your monitor are exactly the same with the ones described above.
