No image from computer with Sony VPL-SC50/XC50/SC60 projector

Sony VPLSC50, VPLXC50, VPLSC60If 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.
