Question about Samsung SyncMaster 910MP 19" LCD Monitor

2 Answers

Blank no video

I have a 910MP that appears to have a blank screen. I say appears, because that is what I thought until I observed it in a brightly lit room and on an angle.
There is video (you can barely see it). What has happened is the backlighting has failed.
I have been able to source a replacement power supply (on the internet)
but am not sure if it is truely the supply or the actual lights themselves.
Is there a way to test this ?

The supply is $200.00 and I could probably by a replacement monitor instead. I don't want to throw good money after bad.

Thanks.
Ian

My 910MP recently developed the bad habit of resetting the Contrast/Brightness/Color/Sharpness settings to 0/0/0/0 all by itself. This results in a "black screen" as well. The cure is to go into the menu and raise the settings again.

Replace the Capacitors in the power supply. Start by replacing the two 1000 uF and two to four of the 470uF. Make sure you replace them with computer grade replacements i.e 105c temp rating and it doesn't hurt to up the voltage either.
This will usually do the trick. If not, you may have a burned out CCFL or one or more of the driver chips that drive the transformers is toast. Lastly there is always the possibilty of a shorted transformer.
Good Luck!

Power turns but screen stays black no


Sounds like you need a new LCD Screen(is the screen a little lit up or completely blank) If completely blank than most likely the LCD needs to be replaced if it appears to be slightly lit up than most likely it is a software related issue.

My SyncMaster 910mp LCD TV monitor switch thus not turn on. The green light bleeps and the screen goes blank. Can you help?


ritchaddison, Problem could be inside monitor. If "cold-cathode-fluoresscent-lamps" fail to stay lit. problem might be the "electronic ballast" circuit needs work done on it. Also check the "switch-mode-power-supply" for typical failure modes that result in "black screen" complaints. Remember this!! Your monitor no different than any other brand of CCFL back-lit LCD display in it's basic design and operation. Software not problem. Only you or qualified electronics technician will repair this unit. Read my and other LCD monitor tech's fixya profiles to make decision on what option you will use on 910mp unit. 12fixlouie

I have an acer laptop. When you turn it on you can hear it running but the screen stays blank


Is the screen black(unlit) or blank? If it's not lit, use a bright torch to see if there is a picture, and it means the backlight has gone, which is an easy fix.

My 4 GB ipod nano has a blank screen but still lights up, blank with NO logo and I can play songs there is just no way to see what you are doing. I unplugged the ipod and the screen has been lit and blank...


First of all try rebooting your Ipod by holding down the center button while holding down on the menu button at the same time. When the Apple logo appears, you Ipod is rebooting.

If that doesn't work, restore your Ipod back to factory setting in Itunes. It could be that the brightness and contrast settings of your screen got out of position allowing the screen to appear blank.

Blank


Unplug the monitor from the computer,
it should display the diagnostic screen on monitor in color.
if not reconnect it and boot computer or attach to a running computer with some stuff on the screen,
get a bright light and shine on the screen at an angle do you see the stuff/desktop.if you do the lamp or power supply is bad.
if the monitor is lit and the lamps work but no diagnostics then the video cpu on the monitor is bad.
