Dell M781s monitor
I have a Dell M781s computer monitor that has lost the brightness. On the
board that is plugged into the crt has pins that are supposed to be 12v & the other 6.3 volts. I have no voltage on these pins. Any ideas what I could check to find out why I don't have the voltage? I don't have a schematic for this monitor. Thanks, Jim Nyman = nyman at kai.net |

no filament foltage is usually caused by bad connections on the
mainboard or an open resistor in the feed from the Line output transformer. You will have to trace the line back from the crt board, should be to hard. Ben "Jim Nyman" wrote in message ...
