Adjustment Knob Becomes Loose - Cannot Turn Off/On
on December 25, 2015
I hope you like taking apart your electronics, because you will eventually have to disassemble this one to fix it. The on/off adjustment knob is secured with a screw. Over time this securing screw will come loose and the know will rotate freely, thus keeping you from turning the unit on or off. The fix is relatively easy, remove the back case screws and tighten the screw securing the knob. I've done it once will little issue, but when you disassemble the device you will realize it is rather fragile on the inside. I'm am on my second time having to do this, but this time around I will use some silicone or other glue to secure the secure the screw. May also use it to secure the other electronic components on the inside to ensure long lifespan.
Biggest only other complaint beyound the knob, is there is no way to secure the light filters. They slip out quite easily.
