Samsung SyncMaster 2233BW 22" LCD Monitor - Answered Questions & Fixed issues

I see this monitor was produced in 2008. I guess you purchased it used. As used monitors cost any where from $10 and up I'd just replace it. It just isn't worth saving.

Turn off the monitor first. Hold down Function button and click F8 key to tell the laptop to send signal to the monitor.

I had a similar problem with my LCD computer screen. I took it apart and noticed a capacitor that was raised up on the flat end and appeared to be leaking a substance. Replaced it with a similar capacitor and works fine, for three years now.

Check signal cables means there's no signal on input. If your PC still shows up on a different monitor then it's a time to replace a mainboard in your monitor.

Most common failures in these LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply C242 470uF 10V, C241 & C242 1000uF 16V, C261 & C319 680uF 35V failed as indicated in the attached picture, replace them at once. If the power supply board is working then it is back light problem, first do a flash light test. If you can see the image in the flash light test, follow the steps how to test back light voltages: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html and follow the steps how to repair back light LEDs: https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...

Samsung 2333 have switching power supply and it can work from 100-240VAC 50/60Hz with out any modification or adaptors. Feel free to use it in USA or New Zealand. You need only to arrange plug converter. Check specifications on Page 49 of 2333SW user's manual available on: https://www.manualslib.com/manual/201694/Samsung-Syncmaster-2333sw.html?page=11#manual Samsung SyncMaster 2333SW User Manual Your Monitor Initial Settings

This usually indicates a failure in the power supply board. Here is a link to a repair kit for that board.http://www.ccl-la.com/catalog/product_info.php?cPath=21_33_68&products_id=116I hope that helps, if so please rate my solution.BuddyMc

You may have problem in the logic board, it uses surface monted components no much chance for DIY repair. Service manual; http://elektrotanya.com/?q=showresult&megnev=Acer&megnev2=AL2216W&kategoria=monitor&kat2=all The cases these days are hard to open, they use plastic finger hooks types, they go in easy but real hard to remove without damageing them. Use thin flat blade to crack open at the bottom edge so the scratches will not be so noticeable, and work your way around, look out for cables attached to the front bezel also.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Check your cables and output signal.

Uhm, monitors don`t have build in sound......

try this right click on your desktop , click on Appearance tab . then click on effects , see if Show shadows under menus is checked if so uncheck it . click ok then click Apply .

Solution for Samsung SyncMaster 2232BWplus:

The problem is bad capacitors: 5 pcs. 820microFarad – 25v and 1 pc. 330microFarad -25v. Replace these capacitors. Then re-solder the two transformers of inverter side. Also re-solder the power transformer and the inductor coil.
To open the casing:
At the bottom of the stand just twist the knob to unlock. Then, use a small flat screw driver beginning from the bottom (left or right) then using a hard credit card (or alike) then slide/glide it in between the cover plastics.

try to change the plug adapter if isnt workink you get a problem inside at your monitor and there need it an expert

Are you using an adapter? The internals might be faulty, so try using a different adapter. Also try using another cable to connect the monitor and desktop. Another thing you could try is checking if your graphics card (if you have one) is properly seated. Finally, check for bent pins on your cable, monitor, and desktop connectors.

Hi there, if you are experiencing something like a white cloud spreading across whole LCD panel, then unfortunately it has to go for a panel replacement .The panels are still expensive so I personally suggest to try buying a new unit cause of the warranty. Cheers.

Hi there, white screen can be disconnected lvds cable , or bad panel...rarely bad main board.Cheers

if it's new then get it replaced...
else u need to get it fixed from a tech shop....one of the bwlow is @ fault....
1 the LCD screen is gone,
2 the backlite (a small tubelite) is gone
3 the invertor board(a small PCB) behind is gone

Llay the monitor face down on the floor (I put it in the styrofoam from the package) and then put it up against a solid surface. Then push the part into the socket before attaching the round base.

I tried pushing down onto the monitor while holding it upright but that didn't work. When I called Samsung tech support the solution above is what they told me to try and it worked.

There are two possible reasons for the color change that I know about. One is simple to fix: a loose video cable. Check that the cable is correctly and tightly seated to both the monitor and the computer. Try a new cable. (If the cable is permanently connected to the monitor, check the computer side of the connection. The cable screws can tighten the connector to the port.)The other possibility is that the monitor backlight is failing. There are places that sell replacement backlights ( lcdparts.net is one vendor). Unfortunately, you need to take apart the monitor to get the size for the backlights for your monitor. The backlights are usually on the edge sandwiched into the LCD panel and hardware.I hope this helps. Cindy Wells

First thing is to remove the 15pin cable completely and closely inspect the pins inside the connectors. Often these inadvertently are bent when inserting the connector. If any are bent, use a fine pair of strong tweezers to straighten the pins. Once this is done, carefully re-attach the PC and Monitor ends of the i/o cable and boot up your PC.If this does not work as a solution, reload the monitor driver for your monitor. You can usually obtain that free from the manufacturers website after entering the model number of the monitor.Good luckPoppa
