Sanyo POA-SP-SU31 smoke housing help


andy barrow

Hi, I have a Sanyo POA-SP-SU31 smoke housing for my video projector that i
us for shows. After a short while the "OUTER BOX ERROR" LED lights.
I don't think its a filter problem as this has been replaced.Both fans are running at full speed.
Could anybody give me any suggestions as to what is going on as I don't have
any service manuals for the box.

Just as a test run to prove the filters aren't the problem, take them out altogether and run it. If the error still comes up then it's definitely not the filters.

Check the fan connections. I wonder if they are monitored in a similar way to PC fans and the internal sensor wire is loose or that part of the fan is faulty.

What else is there to the outer box that could generate an error?

I have taken it out of the roof and found one of the fixing screws jammed under the Control PCB. It still doen't work though now it is removed! Can anybody suggest a sourse in the UK that can supply the PCB.
