Need schematic diagram


A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension.

Schematic?


A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension. For example, a subway map intended for riders may represent a subway station with a dot; the dot doesn't resemble the actual station at all but gives the viewer information without unnecessary visual clutter. A schematic diagram of a chemical process uses symbols to represent the vessels, piping, valves, pumps, and other equipment of the system, emphasizing their interconnection paths and suppressing physical details. In an electronic circuit diagram, the layout of the symbols may not resemble the layout in the circuit. In the schematic diagram, the symbolic elements are arranged to be more easily interpreted by the viewer.

Transit map, a schematic map (i.e. not drawn to scale, stations are equidistant, lines are drawn at 45 and 90-degree angles)

My samsung syncMaster 220 wm monitor will come on for a second then it shuts off and the button just blinks? Whenever i turn on the tower to plug in my mouse my mouse wont work? What do i do to fix this...


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.
(http://michaeljaylissner.com/archive/viewsonic/vx1935wm-3_sm.pdf)
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.

I have a burned power supply. Component # C523 on pcb# E59670 for a Samsung 22in. Monitor M/N 2220WM. What is the replacement part and is there something else that would have caused this to char that may...

I do not see any pictures. Those caps do go bad because they are exposed to about 2000v, so they do fail. If you look at the other three, you should see somthing like 22J 3K = 22pF 5% 3000V. You can get replacement from MOUSER. Most value are from 22~47pF.

Diagram will be impossible to get.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.
