Monitor dark I have a Samsung 175V monitor. The LCD is dark but will work intermittently. When it stops woking, the green power light flashes. When I unplug the video cable from the monitor, a "signal loss" message appears and moves around the screen. I have tried two other monitors using the same cable and they both work. Is the problem with this monitor worth fixing? Are repair parts available and cost effective? Any help will be greatly appreciated !! Thank You !

More info on the Dim/fuzzy problem.. When I took it all apart it did work perfectly, until I put it all back together then it quit working again. After about 2hrs of "playing around" I realized the big metal backbone (visible by removeing the entire rear plastic cover) was causing some type of problem since the monitor would work fine until that part was re-installed. After a couple hours of getting mad and checking for shorts and thinking it was creating electrical interference I noticed the main circuit board was extremely bent.. it was bent down in a corner near a ground post. This ground post was being pushed down by the metal cover. By reinstalling the cover this was causing the ground post to move down a little more, pushing on the board even more... I decided to shorten this post and after I cut it I noticed it was a little bit loose... then I realized it was a multi layer circuit board and the ground attaches to several layers.. not just the bottom... so I re-soldered it with about 1/8" of height taken out of it and NO MORE PROBLEMS AT ALL - EVEN RE-ASSEMBLED. Im pretty sure anybody experiencing a dim screen and/or "locked" auto buttons have this exact problem. I did notice depending on how I wiggled the ground post I would either get a dim screen, locked auto button, or both. More info on the Dim/fuzzy problem..
