I am having some difficulties from our Sanyo PLC_XU73. Our church does not use our projector extensively and is normally only used 1 of our 3 services per week, but it is becoming quite a frustrating problem and I cannot seem to find a solution.
The problem:
Without any warning on some mornings when I power on the projector it will not recognize any that there is any signal present and I will just get a blank blue "no signal screen". This problem has happened with 2 different PCs and in both cases the computer always recognized as a having an external monitor connected. Sometimes a simple power cycle of the projector will fix it, other times I have to climb a ladder and simply un-plug and then reconnect the VGA cable in the back of the projector, then other time it takes a hard reset to solve the problem. But now none of those solutions are working. It also should be noted that this same problem occurred before when I had a signal amplifier in line and I removed it and the problem seemed to go away for the better part of a year, but now it's back. It seems to happen randomly too, sometimes once a week and sometimes it may go a month or two and never have a problem.
I know that this projector is not a unit that would normally be put into a church, but we bought it used and don't have the budget for a quality projector.
Another note on my troubleshooting, when we bought this projector it came with an identical twin I have switched them out and got the same problems so I thought it was a cable or PC problem so I took it home and connected it via a 6' cable and my own PC and get similar problems.
It doesn't make sense to me and I am beginning to think they have a mind of their own. Like they each have the same defect.
Do you have any thoughts on these snake oil filled projectors?
Thanks Guys/Gals.
I will post this a couple other places as well, because I need all the help I can get!
