Question about Samsung SyncMaster 2253BW LCD Monitor
So I bought the Samsung 2253BW the other day and everything seemed fine for a while. Then I watched a DVD and noticed that some of the bright colors appear red-ish. I thought it was the movie or something so I didn't pay that much attention to it at first. But when I got into Photoshop today I was sure something was wrong. When making a smooth transition (with tablet) from white to black, instead of grey I got red-pinkish colors. As the colors go darker they seem to appear normal all the way down to black. But the bright parts are just wrong. Tried to fix it manually and spent like 2 hours in the menu, but nothing changed.
It's so friggin frustrating, cause I can't make a print screen and compare or show visual proof.
I'm pretty sure it has nothing to do with the rest of my hardware. My previous monitor was Dell 1130, but it just started blinking on and off and changing modes - going into sepia and cold tones. It just got completely mangled. Then I used an old Daewoo for a while, but the colors there seemed to be fine, though I'm not entirely sure, cause it had contrast issues(Geez! Talk about bad monitor history)
I'm using the 7600GS with latest drivers and so on. But as I said - it has to be the monitor.
Any ideas as to what might be wrong?
As a quick test I would try connecting the monitor to another PC to make sure the problem follows the monitor. If it does then the likely cause is a circuit board or possibly a poor connection inside the monitor. Since working on this would require opening the monitor case and voiding your 1 year warranty I would recommend you contact Samsung support for a warranty replacement as soon as possible. When you do make sure you mention the problem goes with the monitor and any other troubleshooting steps you have taken. Also the replacement they send will itself be something that was returned and fixed.The only warranty you will get will be whatever is left of your original year so definitely get this taken care of as soon as possible.

The samsung monitor 740n has 85 deg cap at c301 ,c311, c312 all 820 uf 25 v and fuse resistor of 3 amp r401 they all fail monitor does not work since there is to voltage to invertors. replace all the above with
1000 uf 25v 105 deg, replace them all and the fuse resistor too, it should work resolder dry joints. it is advise to change all caps if possible.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
