Question about Samsung SyncMaster 920LM 19" LCD Monitor

1 Answer

The top part (about one third) of my SyncMaster 920LM screen is brighter than the rest and seems to retain simultaneously the new and the previous picture for 2 to 3 seconds before it gradually fades out into the new picture. For example I am in my internet browser and press exit to go into the windows starting screen, the computer (and screen of course) goes into the starting screen but the top third of the screen shows simultaneously the new picture but also faintly the corresponding top part of the previous browser screen - this is only for a second or two. Can you help?

This is usually do to a section of your controller chips dying. This is not fixable by the end user, the only thing I could say to try is to try different resolutions to see if you can reduce the issue.

Samsung syncmaster 920lm wont stop going off and on


Hi,

For this case, you need to open lcd case and try to find power inverter board. That cause by cold soldering joint and you need to check and resolder all them.

Souds like you need in-depth troubleshooting. Voltages checking that will be next, caps have completely flat tops, bad cap can look normal but can have high ESR.

When i turn onmt Samsung SyncMaster 920LM 19 inch LCD Monitor it blinks on the left upper corner for a few moments


WQhen you get strange problem like this, first place to look will be the caps in the power supply section.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor Blank screen,


Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;

No sound on my Samsung Syncmaster 920lm Monitor


This seems to be easy.

1) Your monitor will need to be connected to the sound output using a separate cable, unless it uses HDMI cabling.

2) If that doesn't help, check the sound output using headphones or a different speaker system.
