help! monitor blanks out!
HI! i have an ICL 14C monitor. FCC JVP7133D. Monitor starts up fine,
Raster is okay, display is clear.. but just after a couple of seconds the just blanks out! the LED stays GREEN (flashes when its on DPMS mode).. heater filament stays orange. I can only bring back the video when i flip the power switch quicky from OFF to ON.. then the cycle continues... as minutes go on.. it does stay ON longer. until it really gets stable --UNLESS i restart windows.. and the tale never ends.. there it goes again! any ideas? thanks! -mike |

If the Horizontal Sync is interrupted due to a loss of signal it will do exactly what you describe. The cable is the most likely place for such a problem, but it could also be internal as well. |
