I have two Samsung Sync master 2253bw monitors for my computer and one stopped working. when I turn it on it lights up shows the desktop screen says analog the digital in the top left corner then turns off. At first I thought capacitors and when I opened it up there were 2 blown so I changed them and put it back together, nothing still doing the same thing. I took the one that works apart and put the power supply from the broken one in the good and it works so I tried vise versa and nothing. so I am guessing the only thing it can be is the lcd screen? is there anything else I should check and if this is the problem why does it work for a second or two. also can it be fixed?
