Dan,
Thank you for your excellent advice. I will be ordering a couple of fuses as soon as I purchase another HVPS for ECP 4100 (I have already located another).
Thats right, ANOTHER ONE! Thats because today I finish swapping my broke one and I AM WATCHING A DVD via my htpc and my ecp 4100.
So now for a $1.47 fuse, a ~400$ HVPS, I wonder if I can fix the other 4100 (that i got at the BARGIN rate of 300$).
WHen I took it apart everything appeared fine and when plugged up it did not have any lights, so I checked the PEM and sure enough blown fuse.
It would be a mircale if only the fuse was preventing this (working but not cosmetic) unit from working.
Henrik: Thanks for all of your help. With it I have now got many images and tips to put into the site. I hope to work on that site this weekend. Again, I will post the url to this thread.
