Default Samsung SyncMaster 2253bw repair job

Hi,
Well I did my usual boring chore of taking the garbage out the other day
which actually ended up being not so boring after all!.

I found a Samsung 22"widescreen monitor in my garbage bin!! cosmetically perfect not a scratch on it looks like it was placed nicely in there in a nice bag almost like a burial ceremony the previous owner must have been very sad having to put a 3 or 4 yr old monitor to its grave So I did a little dumpster diving hoping it would be working or perhaps an easy fix.

plugged it in and booted up ...... nothing just a black screen

then proceeded to watch some You Tube videos with my working monitor on Samsung repairs and came to the conclusion that bad caps made in China on the power inverter are a very common occurrence in Samsungs.

So now came the hard part how to pry this baby apart without damaging the perfect appearance of the bezel and back cover it was hard labour and tourture but success no damage.

Here are some pics of the power inverter with bad caps. There are 4 of them C301 C302 C108 and C112 they are 25V 820 UF caps.

I will attempt to remove them and find new ones at my local electronics store.
I'm pretty confident this repair will return it to a perfectly working monitor.

One of the youtube videos suggested changing out the 125V pico fuse which is the little green one at the top left corner beside C301. I don't know how hard it is to get a new one of these but i will leave it for now and just replace the caps.

Tomahawk out


Well I only managed to upload one pic the other uploads failed perhaps Ill try again later.

Hello Tomahawk, You post on the samsung monitor was very helpful. How do you take it apart? There seems to be 4 allen screws on the back, do I need to take them out? I have part of the faces fram removed already. Anyhelp would be appreciated. Thanks again.

I don't think I've ever seen Samsung monitors with allen screws before, but yes, in all likelihood, you will have to remove them. I've had to fix several Samsung monitors with this problem before. Use Panasonic FC, Nichicon PW, or Chemi-Con LXZ series to replace the caps with.

Hello Tomahawk I wanted to ask if replacing the capacitors fixed the monitor, I have the exact capacitors that went out. Any tips this would be my first fix.
