My monitor is a 21" iiyama vision master 512 CRT and there is absolutely no power to it. I think this was due to a brownout and I do not have a ups. I checked the fuse and is ok. When you have a brownout, is there a way to reset the power supply or does it need to be replaced? Does anyone know what happens to a monitor in case of a brownout. No lights, no power at all. Is there another fuse in the monitor. I just found a 250V 6.3 amp fuse. Also, anyone know where you can purchase a power supply for this monitor? Fry's? Or does it have to go to iiyama?

This monitor the power supply is part of the main board.
What is the Iiyama model number HA****, some units take the power in through the stand and there is an internal fuse in that.
Then there is a pre regulator for power factor correction consisting of IC951 & Q950 This provides about 380V DC to C956, the main psu which is supplied by the 380V is IC952 controlling Q951.
If R951 is open circuit then the pre-regulator has probably failed, if R967 is open circuit then the main psu has failed.
