This was my issue right after we got it. I posted about it in this thread.
We had an intermittent "turn on" problem. I started a trouble tag with Sharp customer service, but never followed through with a return. Their techs offered several things to try, none of which worked. I could have shipped it off and hoped for a repair or a refurb. However, new replacement units were in short supply. Besides the "ghost" turn on problem, the unit worked great. I was reluctant to part with it and take a chance on a "pot" luck replacement projector.
So, I worked out a fix. When the Z30K would not respond to the remote control "turn on" command, I would have to get out a 12 foot ladder and go up to it (cathedral ceiling mount).
I would then unplug the power cord and plug it back in again. This would "reset" the projector and it would respond to the remote control. Sometimes, it would go for a week or two before happening again. Then I would repeat the ladder trick and be good to go. Well, this got old fast.
It would have been easier if the Z30K had been on a dedicated electrical circuit, then I could have just flipped the breaker to reset it. However, the Sat receiver, wifi router and other equipment shared the same circuit and I did not want to cycle that stuff off and on. So, I installed a $10 RF switch (for Xmas tree lights) above the Z30K and plugged the power cord into it.. When it refuses to turn on, I toggle the RF switch and turn the juice off and on. The projector resets and we are good to go. On the plus side is that the problem has become much less frequent over time, but it still happens... I still can not figure out why it occurs, but Art at PR
(and the Sharp techs) thought that it's probably related to some sort of interaction between one of my other remote controls or remote codes
on the RF universal remote relay system that I use to control the equipment stack in the other room. Rather than try and track down the "ghost" I just learned to live with him.
The first thing that I would do would be to unplug the projector...
