Re: Samsung Syncmaster 225BW

I received my replacement power board from china (e-bay purchase referenced above) and it doesn't seem to power the backlights at all. I haven't had time to play with it, just plugged it in quickly to see if it would work but alas no luck.

Are there any known issues/differences between Rev 1 and Rev 2 boards? I'm replacing a Rev 1 with a 2.

More info: this particular monitor had the caps replaced 2 years ago. Lately it started flickering. To isolate the problem, I swapped a known working powerboard out of another of my 225BW's...

Re: Samsung Syncmaster 225BW



It looks similar but there is just no way for me to tell. I suspect the different revisions are compatible but I cannot confirm that so perhaps for the sake of a couple bucks, you may want to match it with your current revision. Good luck!...

Re: Samsung Syncmaster 225BW

Nmjwolf,

I'm not sure if this will solve the issue or not but as Selldoor mentioned, the surgery typically involves replacing 6 caps, not 5. Having done it 3x myself, I can see "C107" on your board is original. (It's the small one at the very bottom of the first picture, dead center)

I can confirm you've got the correct polarity for the caps you've replaced although double check the properties of your caps against the list in this thread to ensure they are the correct voltage and type (ESR) in addition to being...

Hey Chez,

Sorry it took so long to get back to you. Some of your caps look bad to me from the pictures but it's hard to tell. In the last picture, the ones in the bottom left look bad.

What you're looking for is for the end of the capacitor to be bulging out a little or even for a brownish (in this case) fluid to be leaking out. It should be noted that even if a capacitor does not exhibit external signs of failure, that doesn't mean it hasn't.

It's cheaper to order parts from digikey and...

Sure,

As a note, make sure you look at all of the listings... often the same seller will list the same item multiple times with different...

Hey Bill,

Thanks for the quick reply. Swordfish... haha I was disappointed Travolta did that flick, I liked it but it seemed a bit cheesy. That said, he followed it up later with Be Cool and other blockbusters like Wildhogs *puke*. I'll send a pic of the setup if you like, pretty decent!

I was poking around on Ebay and found a complete new power board (Rev 0.2) for $22.99 (shipping INCLUDED) out of Hong Kong. Having bought items from China previously via E-bay, I can say I've had great luck with super fast...

Re: Samsung Syncmaster 225BW

First: It can't be said enough... thanks PlainBill, clearly a LOT of hours spent in this thread and others.

I'm the proud owner of 5 Samsung 225BW monitors and I've replaced the caps on 2 of them (my first repair was 2 years ago).

Recently a monitor I replaced caps in 2 years ago began to buzz and flicker then turn off. It is a loud buzz and the flickering was sporadic (not an even flicker). Eventually the backlight would turn off. After letting it 'rest' I could turn it back on and it would work for a little bit then exhibit...
