I am repairing an LCD monitor that has the very common turn on problems.
This is an I-INC IF281D unit with model number showing as HSD1040. I am
in the process of replacing all the capacitors on the PhiHong power
supply board (model PSM217-404-H-R) and have noticed that one transistor
looks like it got excessively hot. I would like to replace that
transistor but have to first ID the part number. To this end I have two
questions...

Does anyone know where it may be possible to get a schematic for the
PSM217-404-H-R power supply board?

The overheated transistor is an SMT device with a code DFRG marked on
top. Any idea as to what that part number may be?
