UPS for projector - 05/17/09 07:18 PM
A couple of years ago there were some interesting arguments about whether running your projector / TV on a UPS made sense in order to protect the bulb from thermal abuse if the power (and hence fan) failed while the unit was running.
This issue became a lot more real for me a couple of days ago; first time we had a power failure while my projector (Sanyo Z4) was running. When the power came back on the projector would cycle on, then after ~20 seconds the "replace bulb" light would come on and the projector would just down. Gave it a day without power and problem still persists, so it seems likely the bulb is now an ex-bulb. I can't see how many hours were on the bulb without a new bulb, of course, but my guess would be 1500-ish.
Now watching BluRay disks in a small area of a 27" CRT TV, connected at 480i via composite RCA. It's... different.
So, what is the thinking these days about UPSes ?
