Question about Samsung SyncMaster 2220WM 22" LCD Monitor

2 Answers

Samsung Syncmaster 2220wm. All of sudden, the monitor went black. It does not show any light at all on the screen. The power light is on (light comes on green). I connected a different monitor, it worked just fine. So I know the problem is the monitor itself. What could possibly be wrong with the monitor ? Thanks, Richard

You might try looking at the screen from a shallow angle; you may see 'ghost' images on it. Make your system do anything that will create some motion, this makes it easier to check. If so, one of two things has failed: - The inverter for the back-light(s) - The possibly single back-light which is a CCFL tube related to a standard fluorescent lighting tube/lamp.
Either of these can be found from several suppliers on the web but replacing the fluorescent lamp (which is much smaller than one for lighting) can be a delicate task.

Power capacitors on the power board most likely gone. You could get a qualified technician to investigate and repair by replacing the blown capacitiors ( you may notice a charring smell from the back of the monitor if they have gone). Cost of replacement is however likely to be more than the monitor replacement is worth. unlike CRT monitors, these are not designed to be easily repaired

SyncMaster2220wm LCD, 3 years old, and 3 weeks. Display flashes on, then goes to black screen.


The problem is in the power supply inverter board caused by bad capacitors and poor solder connections, an attempt can be made to repair or replace the board, If a professional gets involved it will be pricey.

WORKED GREAT FOR TWO YEARS. THEN SUDDENLY SCREEN IS BLACK


Open the lcd monitor and look for the pop up capacitor. If there is, replace it with a new capacitor by soldering it. Most of the lcd monitor having no display commonly capacitor are the main problem. When i had that problem i usually check the electronic parts if there is a leackage or defective electronic parts. Have a nice day!

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.

Hi I have a samsung syncMaster 920N The screen has suddenly gone blank - the power light is showing. I have a second identical monitor and have swapped cables but no difference Is it a repairable fault?...


This happened to me a few months back. I removed all cables and left it for 2 days. Switched back on on it worked fine. That is until yesterday when half the screen went black. I found that my driver was out of date. I have undated the driver but have decided to leave it off and unplugged for another day.
You could try this. You say you have another monitor, i would suggest using it for a few days and the try the old one again.

Samsung SyncMaster 920nw suddenly went black now squeaks/flickers


The 920nw did have a 3 year warranty on the unit but they will be out of warranty now. The flickering power light is an indication of a failure in the power supply board. When the board fails it can't start up correctly and the power shuts down over and over so you get the blinking light and no display. This is a very common failure point on all LCD monitors after a few years of use. There are parts called capacitors on the power supply board and they filter the output power. When they fail the power is not properly regulated and the power supply shuts down and tried to restart so you get the flashing. Here is a link to a repair guide that will show you how to dis-assemble the unit and then what to look for and replace to get it back up and running again.

I hope this helps, if so please rate my solution.
