Hey guys,
Hoping I can get some help with my monitor.
Had this UltraSharp U3014 since new and all of a sudden it won't display any sign of a working image. Unfortunately it's out of warranty so there's nothing I can do aside from attempt to fix it myself.
-As soon as I power it up, I get a black screen with a white vertical band in the center that moves horizontally (don't think the "no input detected" dialog is supposed to move)
-When I try to bring up the menu, the lines just shift to the right side of the screen. I can't see even a tiny bit of the menu.
-When I plug in a source, I can tell there's movement because the vertical lines take up the entire screen and they change as the screen's content changes (picture 1)
-When I run the self test (picture 2), I get an entire red, green and blue screen with some faint black vertical lines in the background, almost like screen burn-in. It looks worse in the photo than it is in person. In fact, I don't remember those lines being there before I ran the monitor for several hours, rather there was a faint bar in the right corner instead which is no longer there.
- The text self test just gives me the same vertical bar as shown earlier.
- Running the monitor for a long period of time adds a few more lines or artifacts like the faint background burn-in like lines, doesn't seem to be temperature dependent.
Also, the refresh rate has slowed down to the point it looks like a CSTN screen when switching between test patterns.
Does this sound like a defective t-con board? Defective main board? Or something more serious?
Please see the attached photos.
Any help would be greatly appreciated.
Thanks!
