Question about Samsung SyncMaster 17" TFT LCD Monitor

2 Answers

Dark scree My Samsung SyncMaster 170MP screen has darkened considerably. I can see the screen icons and images but they are dimmed a lot. It was OK until I lost power. When the power came back, for no appearant reason this condition was present. NO settings were changed. When the brightness is adjusted up or down, nothing happens to brighten or dim the screen. My Questions is: How do I get the screen to brighten up back to normal levels? Please help.

    We have the same problem, the tv works great, but when switched to pc it is so dark you can't use it.

    I am having the same problem. Worked perfect till I shut it off and moved my pc to the other side of the room - now I've got a dimmed screen. Adjusting contrast & brightness has no affect. TV side looks great as usual. Duuuu...What is going on here?

    Same problem but I'm not seeing any solutions.

    I also have the same problem of incredibly dim and blurry PC feed but the TV and video feeds are still good quality -- these feeds have not deteriorated over time like the PC feed. Does this mean there is no apparent solution other than the trash can?

I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.

My samsung 940b it has a clear bright screen ( as normal ) just for 2 seconds then the screen turns dark but you can see very very dim Window logo.Turn off the power ( does not matter for how long ) when...

Shine a flash light onto the monitor, if you can see icons/desktopon the screen then you know you need a new monitor!
You should be covered under warranty!
