Hey guys,
So I was walking home today and i came across a perfectly good looking SyncMaster 216BW that someone was throwing away, I took it with me, tested it and as expected didn't work (Blinking LED, Black screen).
I opened it up and replaced the 6 bulging CapXon capacitors with Nichicon capacitors with the exact same capacitance rating and voltage (5x 820uF 25V, 1x 330uF 25V) on the PSU. I put it back together, and the monitor worked.
The problem is that there are vertical lines across the monitor. The lines are really faded (very transparent), thin, and many in number (Virtually cover most of the screen). It's easy to see them in most darker colors (grey, blue, violet), but almost impossible to see them in White & Black. The lines go over the OCD aswell, so i know its not a video card fault.
It's not THAT bad, but it could get annoying while watching videos, or anything that's not still framed. Any ideas where they're from, or how to fix them?
Oh also, If I have the monitor running for a while (10-20 minutes), it begins to make high pitched noises in no particular pattern.
I have reseated the ribbon cable that connects the Logic board to the LCD panel many times with no luck, I even checked the continuity of the ribbon cable pin by pin with no negative results.
Here are the pictures I have taken:
Note that, it's very hard to see the lines on camera, and it's much easier to see them in person.
This first one shows a paint window with a solid grey fill on the monitor with the vertical lines:
This second one shows a comparison side by side of my LG monitor (left) with the bad Samsung monitor (right) with the same solid grey paint window:
Also, sorry about the change in elevation between the monitors, I didn't have enough room on my desk..
Thanks!
