Remains lit power button - Pentax Optio W90 Digital Camera

Did you try to de-assemble and clean the contact of this button with contact cleaner, take care to not shoot on rubber parts if you have near the contact, it would blown up !

Robert. You have a bad water valve OR completely clogged up filter screens on the valve. My past experience with this machine with this type of problem is to replace the valve assembly. part Number W10364988

I had the same problem with mine, and figured out how to repair the control box. If you would like to have me perform a service on your set go to www.mikecampagna.com/Polaroid

Black uses much less power. It's a device for automation, so you really should not lavish the watts and attention on it unless it has to perform something truly novel.

If you really want to use the monitor though, you can use the function-key combination used to switch the display between internal and external displays.
