Question about Samsung SyncMaster 220WM Monitor
I had the same problem with my Samsung 220wm LCD monitor. I was about ready to chuck it and decided that I would
open it up and take a look - since I had nothing to lose if I destroyed it. I noticed that there was a fried
(exploded and unrecognizable) capacitor on the power board (c523 on a ILPI-055 / E59670 board). The adjacent
capacitor (c528) looked similar and had "N3 3KV SEC" written on it. I couldn't find a schematic online for my
monitor so I did a search on N3 3KV SEC to find out what the capacitance value is for this type of capacitor.
I got a lot of hits for people having problems with both the c523 and c528 but nobody seemed to know what the
capacitance of either is. What I did learn from one capcitor manufaturer's spec page is that "N3" gives the physical
characteristics of the leads of the capacitor (presumably so board designers can know how far apart to drill the
holes for the leads and how big the holes need to be). 3KV was obvious 3 kilo volts, and SEC (if I'm reading the
chart correctly) means high temperature/low dissapation +/- .25 pF tolerance, etc -- nothing on the actual capacitance.
So then I decided to attack the problem from the board angle. What I found is that the ILPI power boards seem
to be used in a lot of different monitors from different manufacturers. So I did a search on ILPI-055 and got
nothing but a lot of other issues with various ILPI power boards. I did a search on e59670 and eventually found a
schematic for a Viewsonic VX1935wm-3 using what I believe is a ILPI-004 power board.
On page 66 of the schematic it shows that c523 is a 10pf/3KV capacitor and that c528 is a 3pf/3KV capacitor.
Comparing all the other capacitors on my board with the capacitors listed for this board, it was vary apparent that
the ILPI-004 is very similar to my ILPI-055. So I went to Digikey.com and ordered Part # 445-2821-ND
(Cer Cap 10pF 3KV 5% radial). I made sure that the temperature ratings were in the 20 to 85 degree C range etc.
Any way, the cap was $0.43 plus $2.00 Shipping and handling and took 2 days to arrive. Once It arrived,
I unsoldered the remains of the previous capacitor and did my usual terrible job of soldering in the new one and
the monitor seems to be working great for the last 5 days now.
Not bad for an amatuer with one year of high school electronics 38 years ago.

its time for u poeple to buy a new moniter .....or get it repaired by a prof tecnician.....the electrons which bambard on the picture tube at a point of time they become weak...n they loose there capacity......so the moniter starts dim and after wards when the moniter heats up it get fine !!!!!!!!!!!!!!!

Ultimately I had to return the monitor to Best Buy where I Originaly purchased it. Luckily I had purchased it between Thanksgiving and Christmas when the the store had a 1 yr exchange policy. They had to send it back to " have a card replaced" ( They're words). Took about 3wks to get it back no charge. Seems to work fine for now but who knows how long this will last. Will probably be my lasy Samsung

If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.

hello i have the same problem, there are 4 lamps (bulbs) inside the monitor when some of them falls the system turn off, cheks and good look

if u can just open it, u can see capacitors blistered just replace it and also see for lost contacts just re-solder..........................if cannot,,,just bring to the nearest samsung service center am sure they will answer all of your problem bout your samsung lcd monitor...............
