Viewsonic 1564 (15") monitor schematic wanted
sounds like the cable to me
"Don Fletcher" wrote in message ... Can someone tell me where I can get a schematic for a "Viewsonic 1564" 15 inch monitor, or if they could email it to me please. I have loss of vertical sinc problem, the screen rolls, the schematic would be a big help to fix the monitor. Please email me |

Thanks Tom. I have checked with a scope at the monitor pin 14 end of cable
right through to pin 15 of stk79905c, and can see sync, the monitor is ok when cold and looses sync as soon as it warms up a little, have checked and replaced electrolytics along the route too. The stk79905c diagram would help me find other capacitors associated with the vert part of this IC |
