Question about Multimedia Projectors
Thanks for this info Guru
I had the same problem. Based on your above post, I did a work
around. (yes- the fuse does need to blow upon replacement)
Epson 7550C with an ELPLP07
I soldered an external fuse holder to the original lamp housing and
wired it outside the case. I put in a 500ma fuse, but it was too
strong for the ELPLP07 to blow. (should be 100ma I think)
(the projector goes to flashing red after 3 seconds)
So to cheat this, I powered on the unit, hit the projector-lamp-on
button, and then withing the first 3 seconds, I unscrewed the
fuse from the holder and removed it ...live.
This faked out the projector into thinking it blew the fuse.
Sure enough, the timer cleared, and I have 2000 hours again.
(And no more flashing yellow lamp light. All green now)
I would have never figured this out without your post above.

The Epson Powerlite 7300's lamp has got a chip on the side of the lamp's bracket that resets the lamp timer automatically when a new lamp is inserted. And it only does it once - first time the unit is switched on after replacing with a new lamp.
The fuse on this chip blows and causes the lamp timer to be reset. Unfortunatelly this is the only way to reset the lamp timer on this model. There is no manual way.
So to cutt to the chase , you will have to buy the original lamp and replace it before it will reset.
Part Number is : ELPLP05
