Question about ViewSonic G800 20" CRT Monitor
After changed the resolution from 800*600 to 1024*768 Horizontal scanning failed. All picture concetrated in the thin (about 8mm) column in the center of the screen. osd controls working only horizontal width not.
Changed back the resolution bat the same problem.
Help me pls.
Huh, it sounds like the monitor's horizontal deflection amp (a big transistor) failed. It is not so if you can feed it a good signal and get a wider picture.
You would replace that thing with a transistor with a similar drive profile (i.e. not a FET), if you practice the right safety; better to use a service tech to do it unless you were trained in it. Alternately, you can try freezing your monitor (wrap it to keep out condensation! I only mention this because it's freezing out, where I am....) and see if this helps the transistor recover; it's not that sage or safe though, because of the condensation/electricity hazard and unlikely event that you will ground a work bench surface to do this test!
Be safe and consider using lower-power-consumption flat screens in warm weather.
