Question about Samsung SyncMaster 2220WM 22" LCD Monitor

2 Answers

My Samsung Syncmaster 2220wm keeps giving me issues. Although most of them I solved, my monitor keeps auto adjusting when I click the power button, then not turning off. Also, it takes multiple times for me to press the button before it turns back on. Any help would be appreciated.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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.

Richathanu, You could call Samsung and find out if unit is covered by warranty!!! If not, then you will need to DIY investigate the units internal "switch-mode-power-supply / CCFL inverter supply". Come back here if you need additional help to troubleshoot your 2220wm unit's power supply. Some can be refurbished for $4 to $7 investment in new electrolytic filter capacitors. Some units CAN'T!!! 12fixlouie

How to unlock the autoadjustment lock in my samsung lcd monitor?


Hi

If you use any kind of LCD monitors for example Samsung or LG or BenQ, you'll see each and every monitor has their auto adjustment of the monitor's resolution. Many people really find it difficult to adjust when it gets locked.

First find you auto button of your monitor

(It should be beside the power button)

Press and hold the button until the box disappears..

Now just press the auto button. It should have unlocked by now.


THANKS....

With Regards......

My Samsung syncmaster 2220WM will not stay on. It


Hello,

The picture board on your monitor has been malfunctioning for quite the period but you did not notice it, since the screen goes blank, it means the picture board of your monitor has developed fault and will need to be replaced.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

The Samsung Syncmaster 2220WM I have started to


blueangel617, If unit covered by warranty, use it first! It's free! Your next option is a possible ??? cash+dead unit swap-out for a same model refurbished unit from Samsung, if they have a program like that??? It depends on the AGE of unit! If you are not planning on doing DIY repair to your unit, or contracting out the work to local technician your next option for you as a consumer/user will possibly be trade-in for new! But, if you buy a new unit, the sales guy might drop the 2220WM on the computer tech's bench in the back room and say to the technician "here's another one to look at! See if you can do anything with it." Well, with a little bit of luck, (50/50 chance) the tech will open and inspect your unit and evaluate the condition of unit's "switch-mode-power-supply" and "CCFL inverter supply" make a decision to repair or not to repair. If the tech see's the "classic" common LCD problem, he just might invest less than $10 in parts and end up with a working 2220WM to give to his kid to use for another 1 to 3 years. Blueangel617, you and only you will determine what to do about your "black" or "black and blank" screen CCFL back-lit LCD monitor. I just hope I haven't confused you as to what to do!!! If you can access my fixya profile and those of other lcd monitor fixya tech's and do some reading, you might find out more options that will be a better solution for your 2220WM. Good luck and best wishes. 12fixlouie north of Windy City.
