Video Asylum

I've been using a PS300 powerplant for my Sharp 10000 series dlp projector for several weeks now and it has a noticeable and non-trivial effect (beneficial) on the picture. The problem I was having without it was noticeable noise in the upper right quadrant of the picture that was intermittent (looked like some distortion of the picture like electronic interference). This is for my flat in London so the power is 220v and, quite frankly, the powergrid here is VERY dodgy (for my place at least -- I have to run a ps600 for my stereo gear as well). Anyway, I haven't had any problems now that I'm using the ps300. Are the colors more vibrant and the picture more 3D? To be honest, not really much of an effect there. However, any distortion that I had before has been removed completely and the picture is rock solid.

The only caveat is that I'm using a US-unit that has the switch turned to the 220v setting internally and the unit runs HOT HOT HOT. In fact, I came across a posting by Paul (of PSaudio) who suggested using the unit upside down (heat vents are on the bottom of the unit) and this has been essential. If I run the unit rightside up, it gets (even with the fan going on it) much too hot and I'm convinced it'll hurt the internals. Upside down? It runs just fine and stays warm to the touch but not hot.

Paul note -- ever thought about just putting those vents on the top?

Anyway, if you want a nice improvement in picture stability hook your projector into a powerplant. This is really the first tangible and obvious evidence I've gotten about this AC purity stuff. I had tried a Tice unit in the past and it didn't really make any difference for this particular problem I had.
