Re: Samsung 216bw



Anyone?...

Re: Samsung 216bw

This monitor stopped working again. It will start up for about 10 seconds then slightly dim for another 5 seconds or so and then go black. It will start up again if I hit the source button or unplug and replug the monitor from the computer.

I thought maybe the caps are blown again. None of them looked bad but I replaced them anyways. This did not fix the problem. I did make few mistakes, I got general purpose caps (not low ESR), I replaced the 2.2uf cap with a 22uf and I did not replace the 22uf cap at all.

What should I do?

Re: Samsung 216bw



So you think it is the CCFLs. Where do I get new ones for this monitor? If they are a resonable price I will replace them and all of the caps or at least the ones that look bad. If the CCFLs are not reasonabley priced, I am going to replace the monitor. I use this monitor everyday for my work and am getting afraid that it may stop working soon....

Re: Samsung 216bw

Looking closer the 330uf cap and the 5 820uf caps are bulging and some even are oozing brown stuff. The rest look fine. I have a radio shack locally but they have a limited supply of caps and do not have the ones I need. Do I need to order the exact ones or can I use something different from radio shack.

Re: Samsung 216bw

No pink but it has a high pitch buz. I will replace all of the caps and see if that helps. If it is the CCFLs, can they be replaced? Anyone have an idea of what the unknown cap is?

I have to order the caps because we do not have a local electronics store. Should I replace all of them including the big one?

OK, ceramic. Not my day job. I am very good at soldering though.

Here is a picture of the board indicating the caps. The five caps with the X on top are the 820uf 25v.

I just took the monitor apart to take the picture. When I turned it back on it did not flicker like normal but it did shut down a couple times. Each time the blue power button light stayed on....

I have a Samsung 216bw that what I think is a cap probem. When I turn it on it flickers for maybe 20 seconds then shuts down. I then have to turn it on apox 15 to 20 times before it stays on. Each time I turn it on it shuts back down by itself after about a second.

I took the monitor apart and found 10 radial electrolytic caps on the power board. I am thinking about changing all of them. Is this a smart idea? Here is a list of the cap I see on the board.

5x 820uf 25v CapXon
1x 100uf 450v JH
1x 22uf 50v CapXon
1x 330uf 25v CapXon
1x 47uv...
