If you have a Samsung SyncMaster 214T, SyncMaster 215TW, SyncMaster 225BW, SyncMaster 226BW or SyncMaster 204T monitor that either has a blinking power light or a very dark picture then this should help get you back running. These monitors all use the NP-20 or IP-58130A power supply boards. Below you will find a full walk thru on repairing your LCD monitor. If you would prefer to watch a video on this repair it is available HERE. To do the repair you will need the following tools: Soldering iron, de-solder braid, Phillips screwdriver, flat blade screwdriver. You will also need the following electronic parts: qty(2) 820uf 25v capacitors, qty(3) 330uf 25v and qty(1) 47uf 50v. We sell a repair kit with all of the parts for $12.00.
Check your power board, if your board uses 2 680uf capacitors in the center then you need to get the repair guide/kit for the Samsung 204b.

Here we have a non functional Samsung SyncMaster 214T 21.5″ LCD monitor. This unit has a fast blinking power light. We have repaired several of these in our shop and they all have the exact same issue with the power supply.
First you need to remove the power cable, signal cable and the stand. To remove the stand you will need to remove the 4 thumbscrews, they are circled in yellow.
To remove the cover you will need to use the small flat blade screwdriver. Across the bottom there are several release tabs, if you insert the screwdriver into the slot the case will release. When you get one corner released just work your way around.
Here is a picture of what the release tabs look like after you have separated the 2 halves. If you work from the front of the monitor and gently pull the faceplate it should separate from the back fairly easily.
After the screen unit is removed from the plastic case we can get down to the repair. We need to remove the power supply unit. You will need to unplug the control panel, circled in red. The remove the 6 screws that are holding the metal shield in place (yellow circles).
Now unscrew and remove the power supply board. To remove the board you need to unscrew the 5 screws circled to yellow and unplug the 4 backlight plugs and the signal cable, all circled in red.
The 5 capacitors that need to be replaced are circled in yellow. We have already replaced the capacitors in this picture. Before replacement all of these caps had very noticeable bulging tops. The top 2 caps in the top right circle are 820uf 25v and the rest are 330uf 25v. Be sure to reinstall the caps with the polarity stripe going the same direction as the old ones come out.
After the parts are replaced just reverse the procedure to reassemble the case. Now apply power and you should have a fully functional monitor again.
