Problem with Samsung 743NX

Re: Problem with Samsung 743NX

First thing to do,is take off the lead between the screen and the Logic Board, and then put it back ensuring it is seated correctly.

Hi, I did what you suggested, but the problem continues, now the problem happens when "turn on" the monitor, but after a while, the problem disappears. It's like something needed to be heated to remove the problem.

Any other suggestions? Thank you very much!

Sorry for my bad English lol

Hello everyone!

I have a problem with my monitor Samsung 743NX, at first the monitor switched on, show image for 2 seconds and then the screen goes black, no image. Only the power button stayed blue on....

What I did was change 3 capacitors (820 μF 25v) and and the monitor turns on perfect, BUT.....starting the computer will appear different colors and the image fades and turns black, and at other times only shows the error in the bottom.

Is very strange, sometimes I can use it perfectly and shows no failure.


Some videos of the failure:
