Take a soft cloth (type used for cleaning glasses) and moisten it with a small amount of water on one corner.

gently wipe the wet portion of the cloth across the screen (if you have any weak alcohol based cleaners you can try it. I have used hand sanitizer before on my 931b w/out problems, I wouldn't use any extremely strong liquid cleaners though).

Use the dry part of the cloth to wipe the area dry, then move to another part of the monitor once you are satisfied.

Hi

This is a problem with a high magnetic field hence you need to de-goz the screen. Or leave it un-used for some time and it will be alright by itself.

Maybe when you were shifting you have kept a speaker with big magnet around the monitor thats why this has happened.

Dont worry it will go bad to normal by itself.

Cant get size from display settings for external 19" Samsung Sync Master 931B cant see start button everything to large


See if you can pull up the menu on your monitor. If you can reset it to factory defaults.

If you still can't see the screen properly then you need to on your computer. Go into the device manager and make sure its seeing your video card properly. Look underneath display adapters and be sure its seeing something other then standard display vga.

If not then your display adapters are missing so once you install those, the computer will recognize your monitor.

Samsung 931B Monitor Screen will not stay


jane657, Hi there. Will you stop pushing the On/Off button on your lcd/fpd. It's Broke. Period. End. Finito!!! You will not fix it. However there is one test that you should do to determine hoe bad the problem is. You will need to reconnect the 931B to a known good pc that has been fully booted and has the WIN-DESKTOP or IE fixya web page showing. quickly connect the931B to the wall outlet and the PC. Turn on the monitor!!! Yes, I know it will only come on for a second..After the screen goes to BLACK, Shine a bright flashlight onto the screen at different angles, 1-2 inches from the screen. Let me know if you see something even though the screen is black. Anyway here are your options as a consumer/user. 1. Check if unit is under warranty. 2. Check withh Samsung to see if they have a SWAPOUT program. You send them your monitor+$40-$90 and they return a refurbished same model to you with a 30 day warranty. 3. Trade in for new monitor. 4. Check with local TV/Monitor repair guy who knows all there is to know about cold-cathode-fluorescent-tubes, their power-source(inverter type) and lcd monitor power supplys (SMPS) 5. Repair on your own. Not recommended for amatures with no solid state troubleshooting skills and no instrumentation for support. Bye for now. I'm louie12fix on fixya or lmistyrel@ aim.com

931B tries to come on but shuts back off


Problem solved by changing 3 capacitors (C112, C113, C316).

Replace the 470uF 25V with a good quality low ESR type and the two 820uF 25V with 1000uF 25V low ESR types.

The 1000uF caps should be 10x20 in size, however I managed to get 13x20 caps in, but it was a bit tight.
