Hello everybody:
I need help with this E71 Viewsonic monitor. I have several with similar issues: - Some dark an unwashed image, looks like normal TRC decay, but i wish to know if is there any way to recover this. Some video circut intervention or so. - In some units ther is a "ghost image", like in a bad-tuned TV, but more soft and stable. It manifest as some vertical white shadow lines in the left side, and some "reflex" images at the right side of the windows. Both are "echos" of the boundaries of the images (borders of display and window frame respectively). I must say that it occurs after a replacement of the Horizontal Output Transistor, after the old one blows. - Ocasionally, it quickly switchs the width, becoming narrow, and then it comes back to normal, it isn't critical, but is some annoying. This monitors, if repaired and adjusted, are for use with CAD/CAM softs, (Autocad, ArchiCad, etc...), so i need to put them as good as i can. Thanks for any help. JCVH ERdM |
