Having problems with your Samsung SyncMaster 912N 19" Flat Panel LCD Monitor ?

Color changes Why did the colors on the screen suddenly go dim and what can be done about it?


Answers :

1) The display settings on the monitor have changed. Check and/or adapt the settings using the buttons on the monitor. You might wanna try 'reset to default/factory settings'.

\015\0122) The computer display settings have changed. Check and/or adapt the settings on the computer, especially scan the 'advanced' menus for keywords like 'contrast', 'brightness', 'gamma'. Or hook up another computer to rule it out for sure.
\015\0123) The inverter in the monitor is broken. This is not uncommon and mostly due to filter caps gone bad (capacitors with a bulging on top).
\015\0124) One of the backlights in the monitor is broken. This would result in parts/half the screen being much dimmer than the others/half.

\015\012Hopefully you still have warranty so you can get it fixed. If not, a complete inverter replacement can be quite expensive and you're better of buying a new monitor. But when it's only faulty caps, which is not unlikely, it's an easy and quick fix for any electrotechnician, replacement caps are just a couple of bucks. You could have someone or some local repairshop check it out first if you like, could be a cheap fix ...
