Well after many months of not using my Barcodata 701s I finally mounted it to the ceiling so I can use it permanently. When I pushed the power button however, all I got was a click and a dead projector. Is there a main fuse or breaker that I can try to reset, or do I have deeper problems? Nothing it seems is easy when it comes to things I own. Any suggestions appreciated, I've got a movie party coming up in two weeks and I really want to get my Barco back from the dead.
It was a blown fuse on the power supply board. Fuse has not blown since a replacement was installed.

Is the standby LED red? If not, you might want to check the fuses on the power supply. _________________ It only stands to reason that where there’s sacrifice, there’s someone collecting the sacrificial offerings.

All LEDs are off. Its as if there is no power at all going to the board(I did of course verify power from the mains). Checked out some of the excellent docs prepared on the site and pulled the power supply board to test. One fuse, which I think is the Standby Power fuse is blown. The rest are fine. I've attached a picture of the location of the blown fuse. Hopefully it will be as simple as replacing this fuse, but I have to wonder... If the fuse blew once, why wouldn't it blow again? Any further information would be appreciated. I'm wondering as well.. Would this tiny 125mA fuse cause the whole system to go dead?
The fuse in question is just to the right of the red transformer pictured.

Failures of the power supply are pretty common. Try a new fuse, but like you said, it will probably blow again. 125 mA fuses are hard to find, you can put in a 250mA that is easier to find. A dead short will blow either fuse again.
If you're not a tech with good soldering skills, stop now, and send me the board. I can repair it for $175 incl return shipping, assuming you're in North America.

Well the board looks like it uses all through hole components(which is mindboggling btw, I guess it really is old) so I wouldn't have a problem taking a soldering iron to it, but I don't have the diagnostic skills to find out what blew. There is also the time factor. The only reason I woke this beast was for an annual movie event at my house. So I'll certainly try a new fuse for the quick potential solution, but any repair advice would be appreciated. You can see the wear on the green tube.. This isn't a projector I'm willing to put a huge amount of money into.
And Curt, why is it that the only decent projector tech has to live in practically the furthest town away from my house in NA? Ever consider the northern Virginia area? It's great!

Alright, so I've made forward(ish) progress. As Curt mentioned the 125ma fuse wasn't available, so I got one that was 300 and some mA. Set powered right up with that fuse, so I put the power supply board back in, put the lenses back on, and started the setup process. After running for about 40 minutes the set put itself into standby mode. Sending the standby command causes it to power back up, but after a much shorter time - something like a minute or two - the set again puts itself back into standby mode. This time I do have an LED status light, the innermost red, which may just indicate standby, I don't have the manual in front of me. I was running the projector with its main cover off since I needed to adjust lens focus etc, in a 75ish degree room (I'm sure a couple deg F warmer at the ceiling). Could that cause it to overheat and shut itself down? That's my theory since it ran for so long on its first run. Does the projector cool better with its cover on, or is this a condition that I should be worried about?
