image from computer with Sony VPL-SC50/XC50/SC60 projector
 If
you are unable to get an image on your Sony VPL-SC50, VPL-XC50
or VPL-SC60 projector using a laptop computer this tip may save
you a lot of headaches and time. There is a poorly documented
and poorly located (in our opinion) switch on the bottom of these
Sony projectors. The switch is marked 75ohm, ON/OFF, and is located
just below the serial number plate. Make sure this switch is in
the "ON" position.
This
is a termination switch for the 15-pin RGB input. We feel this
is a poor location for the switch since it should be near the
connector it controls, plus it can inadvertently be switched into
the wrong position by sliding the projector across some types
of surfaces.
If
you are even able to locate this switch in the operating instructions
for the projector, you will discover a poorly worded description
that tells you "Normally set to ON. Set it to OFF when the
projector is connected to a computer or monitor." We have
to assume this confusing phrase is the result of an incorrect
translation from Japanese to English. This incorrectly tells you
to put the switch to OFF when using a computer. Don't believe
it!
NOTE:
This problem is known to occur with Compaq Prescario 1255 laptops
and is likely to occur on any newer Compaq models. It will also
occur with any computer which will only output a signal when it
detects it is connected to an external display. When this switch
is in the OFF position, most computers will not detect that the
projector is connected.
