Re: Samsung 226BW
Hello EGuevarae
Yes, the image is normal for about 2 seconds, and after that I can see it very dimly using a flashlight.
I have a small Sony model SDM-X52 that works fine.
Could I test with that one?
Thanks!
Another thing.
I think that the dim backround image was a little easier to see before I replaced all the caps.
I think that I could just barely see light and dark areas without using the flashlight.
Now I need the flashlight for sure....

Re: Samsung 226BW
Thanks again
No, I hear nothing like what you mention:
"noise between the On and then OFF , like a hiss, or a red/pink hue in the screen?"
Nope.Leave a comment:

Thank you for reading!
My screen does the same things as it did before I replaced all the caps as described in this thread.
When connected to [power] and a video source, I see blue surround light at power button in the bezel, and all online images on the LCD, EVERYTHING, for about 2 seconds, and then it goes black.
I can also hit the [MENU] button and see the MENU for a brief time, but this does not repeat.
I am not sure if I do that before replacing the caps.
I see the [analog/digital]...Leave a comment:

Yes, I clipped the leads.
Not easy, since my pointy wire cutter is a little gap-toothed on the pointy end.
I had to search out my cable cutter pair, with a better edge.
Also, I decided to re-do one connection, a little too close for comfort visually.
I think I got it right, but next time I will select the bend direction more carefully, and leave the leads more vertical.
Here are the spec sheet numbers on the Beckman:

Re: Samsung 226BW
The new caps arrived today, and I installed them.
That was fun, but I think I need new glasses.
Hooked everything up, and I still have "2 seconds to black."

Re: Samsung 226BW
Ack...it's so much stuff...I am an amateur!
(@ PCBONEZ, I love sushi, and I'm a cook.)
I could have bought these from the Capking website, but the ZLK series is not on the "good" list:
[url]http://thecapking.com/25zlk820.html[/url]
I have plenty of time/patience, and a few more dollars to buy other caps if you think it is a good idea.
Why bother soldering if the cap is doubtful?
What caps would you put into this project?
Thanks again for your time!

Re: Samsung 226BW
My board is different than the one in this thread:

Maybe that is a different model, the "SyncMaster"

I don't see those caps on my board.
Is it possible that they used 25v 820's instead?
I have 5 of those.Leave a comment:

Re: Samsung 226BW
uh-oh...
Lead spacing!
2 of the caps I purchased have different specs for lead spacing than the ones on the board.
Rubycon RX30 50v 47uF 8X11.5mm
The cap from my board is 6.5mm with 2.5 lead spacing, the rubycon is 3.5 L.S.
United Chemi-Con KZE 25v 330uF 8X15mm
My cap is 10mm with 5mm L.S. the new one has 3.5 L.S.
The other ones seem to be a match.

Nichicon PM 50v 22uF 6.3X11mm
Will they work?
Thanks for your help!
Thanks PCBONEZ!
Any more soldering tips will be much appreciated.

Re: Samsung 226BW

Thanks for your help!
The cap locations are pretty much memorized after so much time scrutinizing things...only 4 types total.
All recorded by photos posted here, and specs.
I have observed that cap locations are marked on the top deck with a circle, half black, half not, that seem to correspond with pos/neg leads on the caps.
Cap numbers start with "C", printed on the top and bottom of the board, including pos/neg notation.
The tops of my factory caps were hand-marked with a sharpie swipe...Leave a comment:

Re: Samsung 226BW
Update:
I visited Home Depot and bought a new soldering iron, Weller SP40LK.
A 40W iron with 3 tips. $18.00
Like this:

My only soldering experience has been attaching flexwatt heat tape to power cords using an age-unknown radio shack pencil iron.
(Yes, I keep snakes.)
Very beat and old tip seemed too bulky for circuit board work so I bought the Weller.
I also searched internet for caps until I found this...Leave a comment:

Re: Samsung 226BW

I have a soldering iron and wick.
But I know little about circuit boards and never did this before.
Is the red arrow the "filter" that you replaced with LXZ component?
Are the green components caps, and did you replace all of them?

Thank you for that, very interesting, "2 seconds to black", exactly!
I had no idea...
I will follow as much of the diagnostic as possible.
Perhaps I can even find somebody with an ESR tester, or buy one.

Re: Samsung 226BW

I connected the monitor to a signal, and power.
When pushed, the power button shows blue light around it.
The monitor lights up and shows a proper display for about 2 seconds.
Then it goes black.
Deep in the black, I can still see a very faint image of the proper display.
Very very faint, I cannot discern text, just light vs. dark areas.
I made some pictures of the power board before reassembly.
Thank you for your help!

Re: Samsung 226BW
PlainBill...you would ask me that!
I did not test the monitor with a PC...
My brother has been using it for 3+ years, and it died on him.
Off warranty, and frustratingly kaput, he bought a new one and dished the dead one to me.
I assumed that he checked for the obvious problems; he is pretty OCD.
Now, it's in pieces on my dining table.
I will plug together the components and answer your question tomorrow.
Thanks!

Samsung 226BW
I inherited a "dead" monitor, Samsung Model 226BW.
The screen is black, but the power button shows blue light surrounding it.
While trying every adjustment button underneath the lower right edge, the screen will occasionally display a small white rectangle in the upper left screen which says "digital" or sometimes "analog". They disappear on their own.
A Google session revealed that there were many failures with this model, and many seemed to involve bad capacitors on the power supply.
I pulled the case apart, and visually inspected...
