Greetings everyone!
I apologize for the amateur post. I have been lurking on these boards for the past week as I've dealt with recent issues of my Samsung Syncmaster 245BW. It would appear that this monitor is prone to some common specific issues and I have tried to follow along with other suggestions in other threads, but have come up short.
The monitor was working fine up until a few weeks ago when it suddenly started being fussy about being turned on and off. It works fine when it is powered on, but it began to not power back up when pressing the power button on the front. When this happens, the screen stays black, the blue led on the power button does NOT light up, and it would appear to be totally inert.
Interestingly, if you let it sit for long enough (and this time period seems to have grown longer and longer so that now it doesn't seem to work at all) and then went to power it on, sometimes it would turn on just fine and would be usable until the next time it was powered off. Then it won't power up again.
So I did some research and quickly realized the power board frequently has bad capacitors and some select faulty resistors. Initially, I just replaced the two most commonly faulty capacitors that were visibly bulging with some leakage on top. I put everything back together and it was still totally unresponsive so I almost considered it scrap then. Lo and behold, the next morning I come out and the monitor is on. At this point I was completely clear if the replacing of the two faulty capacitors did the trick, but it made me feel slightly more confident about me not making things worse via repair error. Unfortunately, I had to power it off as I moved it back to my desk, and of course it wouldn't turn back on once I had it in position.
This led me to pick up some some 68ohm resistors to replace the three that are often faulty in addition to two more capacitors to swap out. I just finished replacing all these parts, put everything back together, and still am striking out.
At this point I'm about ready to settle for buying a new power supply board via eBay for $50 as was mentioned in another thread, but I'm also concerned that it might not be the problem.
I have very limited electrical engineering knowledge and am completely self-taught as far as saudering irons and multimeters go although I now own both tools. I'm also aware that the pros would like pictures of the power supply uploaded as well as the model number, etc. I'll add those tomorrow, but I'm burnt out on working on it for tonight aside from writing this post.
I appreciate any and all help and I apologize if this just seems like another repeat thread. I used the search option and went through the threads that came up, but most of them were issues with the screen staying black, but the blue LED *does* come on, where in my case, it *does not*.
Again, thank you!
