Then you have to remember or mark which sockets are 220, so you don't blow stuff up, since we don't have different socket types for different voltages Getting both voltages where I live isn't that simple, as we'd get 380V line-to-line voltage. One of the states neighboring mine has 110 (actually, 127, but we commonly call it 110), but someone living there could have their house wired with 2-phase 127V to get both 127 and 220V in the same household. For example, where I live we have 220V line voltage. In the pic showing it running I have the brightness turned down to the very lowest setting.Īh, let me clarify: it's not like both standards are there (officially) side by side at one given place, it varies according to location. Also the lamp is LEDs, so no short-lifetime HID lamp to fail.

This is a really nice projector, very small, with lots of inputs, and even WiFi video input. I just popped it back in, and screwed the case lid back on. It had slid out of the sleeve bearing and wedged. Someone had bumped the projector sharply enough to dislodge one of the fan rotors. Mostly they are held in place by the field magnets. The two largest fans (still tiny) have rotor shafts that are only held in the sleeve bearings by quite weak plastic clips on the shaft end-ring. With the cover off they can be simply lifted out. They are not even screwed in, just slid into slots, with foam tape to prevent vibration noise. It powers up, then after a few moments says 'fan fail' then 'over-temp, shutting down'. It had been thrown out by a large institution due to being 'faulty'.

I was given a very cute, modern, small LCD projector, a DELL M900HD. To be more precise, what was your highest ratio of repair ease to value of equipment? This was mine, a few days ago.
