Smudges on my 37″ Westinghouse LCD LVM-37w3

Filed under: Uncategorized — Tags: , , , , , — Hugsie @ 2:01 pm

I own a 37″ Westinghouse LCD monitor, model # LVM-37w3 which I’ve had for about 3 years now. For about 3-4 months I’ve noticed these dark smudges on my HD LCD monitor.  It is an HD monitor, not a Television since it doesn’t have a TV tuner, nor does it have speakers.  It does accept audio in with RCA jacks for audio out.

See below for snapshots of this problem I’m having. This is not a surface scuff, or smudge of dirt otherwise it would effect all colors. It seems to be only effecting blue pixels, and colors that use blue (cyan, green, etc) since full white, full yellow, and full red won’t show this blemish (see images), unless I darken a color (like gold, and dark red).  All shades of blue will show this blemish, and shades of gray do show this smudge quite predominately.  There are also two more smaller smudge-like blemishes at the top left of the screen not shown, but they aren’t as intrusive as this one.  I really don’t know what caused this to happen. I usually use a old paint brush (never used for painting, only dusting) to dust the screen with. But I have used a screen cleaning product that comes in a spray (Monster ScreenClean) bottle that you spray onto a lint-free cloth (looks like terry cloth) and then wipe the screen with.  I’ve used this on ALL my other LCD displays (laptops, netbook, my PC’s 22″ LCD) with no problems. I  don’t think this stuff is to blame otherwise there would be smudges like this all over my screen.

If anyone can help me fix this would be greatly appreciated, I doubt I’ll be able to do anything. Unless there some sort of test pattern I can run on my monitor that will work out this problem.


  1. Almost the exact issue with my westinghouse 37″ after 3 years of good service… Had a smudge like this start to appear in the upper right, then a smaller one in the lower center…. Please let me know if you find a solution.

    • One day I blew compressed air on my screen too blow dust off. I do recall spraying a puff of the super cold liquid onto the screen by accident, but it evaporated, and I THINK this is what MAY have caused this blemish on my screen.

      It’s not like this blemish started small and grew worse. It was just THERE one day when I fired up my 360 to play some Fallout 3. It’s also not getting worse nor better, it stays rather consistent… and I doubt there’s a solution to this.

  2. I have the exact same smudge on my Acer 3705 HDTV, which is now about 2.5 years old. If I find a fix, I’ll post it.

  3. Similar issue on my dell 21″ monitor. 6″ x 1″ wavey light gray smudge in the middle of the screen. Notice it mostly on a white background. Has been there a couple of years.

  4. Same problem with my Acer HDTV. Very frustrating.

  5. These are old post, but I wanted to add a comment in case someone comes across this thread looking for a solution. The black smudges usually indicate “dead-pixels” and cannot be fixed. You can check this site for some tips on “stuck-pixels”. I have also heard of black dots, lines, and blurring which are all different issues. The smudge kind of looks like something that can be cleaned and will usually get worse with age. It shows up more on light backgrounds. Hope this helps.
