When i come back to my sync master 2233rz monitor after leaving it alone for atleast an hour, half of the screen goes bezerk and the only way i can fix it is by restarting my system , please tell me what i...

Hook a spare monitor to your computer, if okay! the problem is in the SynMaster, but if both show the same it indicates a video graphics card problem in the computer, Hook your SyncMaster to the computer and change the video cord from the computer to the monitor just to be sure. If no change! it is time to replace the monitor "the LCD panel is defective" not cost effective to repair.

All of a sudden my 2233rz stopped powering on. Screen just went black midway through browsing...checked the kettle lead, it's fine. All cables are fine. Any suggestions?

Hi Kevin,

First of all, thank you for posting your question here at

My first advice is to ensure that your AC source(outlet) is live. Try to plug it in to a known working outlet to confirm that the power source is not the issue. If you are using a surge protector/AVR, try to directly plug the monitor's plug to the outlet.

If you confirmed that the AC source is not the problem, then this is an indication that the fault is inside the unit. You have to check first the power supply board's fuse. Check its continuity, if it has a continuity, then the fault is on the voltage regulator circuitry and/or other circuitry on this board, I would advice you to replaced the entire power supply board. Click it here for the replacement.

If you found it open, you have to replaced it with same current(ampere) ratings and then try to power on the unit again. You are lucky if the replacement fuse resolve the issue. Sometimes fuse fail due to voltage surge/flactuation, aging however if the new fuse didn't resolve the issue, then you have to replaced the entire power supply board.

Also, check if your unit is under warranty period, avail it because the manufacturer will fix it for free. Opening the rear cover will void the warranty.

Hope I helped you.

Have a nice day!

Good luck and take care!

Kind Regards,

SyncMaster 203B (Black) LCD Monitor: Monitor will not stay on (Samsung Syncmaster 203B)...

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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:
Post back what you see inside so we can guide you further and it will help out other people in the future also.
