Default Viewsonic schematics VX910

I have a VX 910 lcd monitor and I need the part number for a transister on
the power board. The location is D660. Does anyone have or know where I can
find the schematic for this monitor. Or know the part number for the
transister in question. Please reply to email at if
possible or here.

Thankyou

No part number. The part is burnt to unreadable.

Thanks

I have spoke with them and they were no help. They wanted to sell me the
whole power supply for $80 plus tax and shipping. They won't sell the
schematics for it either.

Don't you hate when that happens.
Have you tried to contact Viewsonic, they have a rep in Canada.

The "D" in "D660" would suggest that you have a diode, possibly a
Schottky dual diode. Is it on the secondary side? Which rail? How much
current?

I believe it is a dual diode but I can't get any info from it.

You can guess its specs by looking at the load that it has to supply.
For example, does it supply the +5V rail? What is the voltage rating
of the associated capacitor? What is the rating of the monitor's power
pack? How much power does the backlight require?

A very rough guesstimate might work like this ...

Power required by electronics = rating of power pack - rating of
backlight

Diode current rating = power required by electronics / 5 volts
