Question about Samsung SyncMaster 930B 19" LCD Flat Panel Monitor

6 Answers

Black screen When i turn my monitor on, there is nothing displayed on the screen. The screen appears to be off, but it is actually on. I've tried checking the display settings, automatic settings, and also checked the plugs and cables and all appear to be in place. The green light is on which lets me know the power is on but the screen shows nothing. Please help!

Re: Black screen

The cold-cathode tubes (four) are used as a backlight, i have same problem and as far as i have investigated, there is problem in one of the cathodetube power-inverter, maybe dryed electrolytecondensator.? It do not help if one tube is disconnected; the other inverters still seems to fail.

Re: Black screen

OK, I have read these reponse but do not see a fix. My screen was fine until; I woke up and turned it on and it stayed black. I checked all connections, there is a power light on. Diconected and hooked up a regular monitor, working well. Need to know how to determine if it is dead, which I can not imagine as I have had no trouble at all with it. Please advise on how to trouble shoot.

Re: Black screen

Going by your description, it is indeed the backlight, especially since the menu is dim

Re: Black screen

If you can get into the menu your monitor should be ok. check the cables to the might have a lose connector on the videocard.wiggle the cable and watch the monitor. if nothing happens you might have a bad videocard. best way to chack monitor: connect it to a known good computer......

Windows 7 - adjust monitor screen??? using a 15" monitor and now have black space around picture.

Control Panel/Appearance and Personalization/Display/Adjust resolution. Try higher resolutions on the list.
If that doesn't do it I would go to Device Manager, and update driver for display adapter. May need to go to the manufacturers website
and Support Tab for drivers.

Black horizontal lines across entire screen.

Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now. Pull up older posts there or do a search by type in the Brand Name of your device in the Search Box, at the top right of the display window.

Black display

You say black display. Not sure what you mean. Either the monitor is working or it is not. If you see nothing on the monitor and the power light is yellow, then it is not getting a signal.
If the power light is green and you see nothing, look really closely. You might even shine a flashlight at the monitor to see if there is actually a dim display. If so, the backlight has gone out and needs to be replaced.
I'm assuming that you have tried to brighten the display with the monitor controls.

I would try this monitor with another PC first to verify that it is not PC problem.
Most common failures in the monitors are due to bad caps in the power supply/inverter board, we want to find out first if it is the monitor or the PC problem.
See examples of failed ACER due to bad caps here:

Learn about bad caps:

Capacitors kit: he can make you a set of caps for you.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Monitor screen goes out (black) 2 seconds after turning on

Your site is extremely misleading and fraudulent. I was under the impression that I would at least get a hint at what might be a problem instead of you folks making me wait to get a money for something answer that you could have displayed on your main page. Places like yours have no place on the internet and I'm going to find out what I can do to report you.

Thank's for nothing
