Question about Samsung SyncMaster 191T 19" Flat Panel LCD Monitor

1 Answer

No more image on SyncMaster 191T...but

Hi, I have a strange issue with one of my monitors. It has worked several years attached to a desktop, and someday it just went black. Completely blach, you even don't see any image in the back, as it normally appears when only the backlighting is defect. Now, the strange thing is that when I plug the monitor to a Laptop, it works. I have tried to plug both VGA and DVI to a desktop, neither way it works on a desktop. Does anyone have an idea about my problem?

I would suggest that your Video card isn't working correctly.. OR the drivers won't work properly. Try a replacement Video card.

The monitor is a Samsung SyncMaster 191T. My cat laid down on the keyboard today and now I am looking at an upside down screen. Can you help me out?

If you are in Windows XP, you can use the following key combination:
CRTL + ALT + up arrow
I am not sure if this combination works in Windows 7.
Good luck.

SyncMaster 191t Screen is to dark. Brightness is set to 100%.

make sure you have the latest video driver.

Some video drivers you can configure/enhance your desktop settings.. ie. brightness, gamma, contrast..

If you're using windows, right click on your desktop, click Properties, choose the tab Settings, then click on the Advanced button. Choose your video card tab, and continue accordingly.

You have either a bad inverter board or burned out backlight fluorescent bulb. Very common on this monitor.

Sounds like the invertor board in the monitor is bad or the LCD screen has had it and needs replacing.
