Having problems with your ViewSonic VA800 17.4" Flat Panel LCD Monitor ?

Short, 3/8", horizontal blurs

\015 I have a Viewsonic VA800 monitor that displays horizontal blurs\015\012emitting from objects on the screen. This gives the impression of\015\012movement.\015\012 Any thoughts? I don't want to give up the monitor. I like the vertical aspect.\015\012 Thank you, Dave Johnson , [email protected]\015

Answers :

I posted this answer on another "white streak" question, I suspect this is right:

This issue presents itself in different ways in this monitor, in the\015\012form of smeary video, or color changing from the left to right, or as\015\012you indicate, a smear following text. I know this as I own this\015\012monitor, and have repaired this myself. There are three 1 mf\015\012capacitors, surface mounted on the control board inside the monitor\015\012that fail. They are in the RGB input lines, and when they fail they\015\012cause distortion of the RGB signals, causing what you see. They are the\015\012three caps you will find in a row, spaced maybe 14mm on the board\015\012between the VGA connector and the processor chip. I would replace all\015\012three, observing polarity markings. You can get by just fine using\015\012old-style thru-hole caps, just form and clip the leads and solder 'em\015\012down on the surface-mount pads. I highly recommend proper soldering\015\012tools for this job though, especially for the removal of the old parts,\015\012they don't want to come off unless you can heat both pads at the same\015\012time.\015\012\015\012

My Samsung 740n monitors look blurry. When I first set them up, there was no problem at all for about a week. But after that, the screens get horizontally blurry (I'd describe the blur as having similar appearance to the "Motion Blur" filter on Photoshop). I already went through 3 Samsung monitors of the same type and they all got blurred like that after a week. What's wrong?
