Re: Samsung SyncMaster 943NW partially fixed, trying for 100%

I finally got around to fixing my monitor, after a couple of months, so I thought I would post an update on this thread.

Thanks to the insightful advice I received here, I confirmed that there was indeed a problem with the inverter. The tubes did not look fresh either. Replacing either or both looked like a lot of work for me and possibly a technical challenge.

So I had an epiphany. What if I replaced the CCFLs with LED strips. After all, they are there to light the LCD panel and LEDs do...

Thank you both so much for your answers!

Now, I just need to find some spare time to test the inverter and tubes. I will post the results and some pictures.

Hey, I bought this Samsung SyncMaster 943NW 20" monitor in a flea market for 10EUR.
I was pretty optimistic that it might work out of the trashcan.
It did not.
It would turn on and I could see the faintest flash of dark grey, while the power LED stayed blue or blinked when the VGA cable was unplugged.

When I opened it up, I noticed a blown cap and I replaced most of them, except for the large 100μF 450V one. I did a few brief tests and it seemed to be working fine, so I closed it back and was filled with this warm feeling of accomplishment.

Cheers from sunny Athens, Greece!
I am a software developer who recently started tinkering with all the nice stuff under the hood. I have been trying to repair a few monitors and TVs and stumbled upon badcaps.net.
This is bad news for me, as it has inspired me to do more repairs ;-)
