Hitatchi ED A110 Ultra Short Throw Projectors

[E_G_R2]

Hi,

 

we have 3 of these in the school and today we had 2 short power-cuts within minutes of each other. All three of these projectors now won't work. There is no power light on them even though the power to the projector is working. Anyone know if there is some setting that needs fiddling with when they have been switched off without powering down.

We have the ED A111, and I know these have quite a few security options, although we don't use them.

 

Looking at the service manual, p34 lists the security features - https://estadoc.hitachi.eu/servlet/FileViewer?DocumentName=YK-0599E_CP-A100_ED-A100_ED-A110.pdf.

 

If there was a security lock on power outage, you'd surely have come across it already by now, though. I'd tend towards them being fried by a power surge, but all three of that model and nothing else sounds unlikely, doesn't it.

Fixed!!!!

 

The answer is in the manual but it doesn't really make it clear what to do.

 

Turn off the unit with the rocker switch and unplug.

WAIT at least 10 minutes if not a little bit more.

Plug it back in and turn on with the rocker switch

Wait a minute then the red power light will come on

Top tip! I'll remember that if any of ours pull the same stunt.

Wow we have/had over a hundred of these... completely forgot that they do that in some circumstances!
