Question about Office Equipment & Supplies

Open Question

I have a proxima DP8000 projector. It initially would not turn on. I removed the main board and cleaned the edge connectorfrom the power supply board that plugs into the socket on the main board and got the unit to power up. Now when I turn it on it lights up and projects a "Searching" message in the lower left corner. When that times out a message that says there are fan problems and the projector will shut down shortly and to unplug the power cord before trying again. The lamp turns off then the projector shuts down and won't start up again until the power switch has been cycled or the cord has been unplugged and plugged back in. There are six fans; an intake fan on the left side towards the front, a small fan blowing on the left side of the lamp, a small can on top of the light guide housing, and three fans in a removable panel on the sight side. All are working. I would really appreciate any insight into what might be causing this problem.

SOURCE: the source is constantly switching from video to computer

try brand new cables and reflashing the firmware. if this fails then your main board is likely the culprit.

Lamp wont stay on

this family of projectors have an issue with the edge connector from the power supply to the main board. the edge of the power supply board (that fits into a connector on the main board) has solder "fingers" that get pitted and start to lose conductivity. resolder them and take a jewlers screwdriver to scrape the pins inside the connector and slightly bend the pins inward to insure a good connection. if you aren't so good at soldering, you could always send it in to an infocus service center for repair. try they're really good.

Ask Proxima will not start up

If it has no power at all or has power but fails to start, it is most likely the power supply needing to be upgraded or replaced. If you look at the projector with the top off, there should be a green wire going from the top of the main board (it is soldered to a orange cap in a group of 4) leading to the underside of the power supply. If you don't see this then your power supply is probably one that was never upgraded.

Powers up but shuts down right afterward

there is a edge connector on the power supply board that goes into a socket on the main board. this connector gets corroded after a while and needs to be resoldered. you could do it yourself (if you're handy with a soldering iron) or send it in for repair to an infocus authorized service center. try av solutions in ny. they're pretty good.

Stays on for 5 minutes and then shuts down. No

the edge connector on the power supply that attaches it to the main board needs resoldering. you'll have to remove the top case and the main board to get to the power supply. use a soldering iron to resolder the fingers on the edge of the power supply. put it back together and it'll work fine.

I have a proxima dp6150 projector

the running problem with the c9/c9hb family of projectors (including yours) is that the edge connector on the power supply than fits into the socket on the main board becomes corroded and loses contact, causing problems. solution: remove the top cover, the main board, and the power supply. using steel wool, rub the soldered parts on the edge connector to get rid of the corrosion and pitting, re solder the connector strips (lightly), and take a small flat-head screwdriver and scrape the corrosion off of thefingers inside the socket on the main board. blow out all of the dust and steel wool bits out of the projector and replace the parts.

DLP Infocus Problem

first of all, the infocus lp 790 is an lcd projector, not a dlp. second, the light filter in front of one of the lcd panels is burnt, and unfortunately cannot be purchased separately.
