Ans: Usually when
you get a blue screen, it indicates that the system is not sending a
signal to the projector. Follow these steps to troubleshoot.
that the power is on for the Extron board. If so, make sure the power
is on for the device you are intending to use.
2. If you are
using a laptop, often times the laptop must be connected to the Extron
board prior to power up in order for the interface and recognition of
the device by the laptop.
3. If the
devices are connected and turned on, make sure that the button on the
Extron board corresponding to the device you wish to use is pushed. A
red light next to the button on the Extron board will indicate that the
button has been pushed.
4. If the blue
screen persists, check to see if any of the other devices are working.
For example, if you are trying to use the VCR and VID1 has been pushed
and you are getting a blue screen, try pushing the PC2 button to check
if the computer image comes up. If it does, wait a few moments then
retry pushing the VID1 button. Remember, pushing the buttons too
quickly on the Extron will lead to system overload and a blue screen.
5. If this
does not fix the problem, try the VCR tape and see if you get sound. If
there is sound, chances are the system needs to “catch up”. Most
likely, simply powering down the system, wait 3-5 minutes and power the
system back up in the normal process will rectify the problem. If there
is no sound, go to next step.
6. Check the
cabling to make sure there are no loose cables. Connect any cables that
may have come unconnected. If that is not the problem, contact the
system administrator or the website for further assistance.
