Canon DR7080 won't come up--

If you want to keep your important data, use some softwares can solve thewindows won't startproblem most quickly, and no data will lose. Besides, it is very easy, even the people who lack of computer knowledge can deal with windows won't boot issue.

I had the same problem. I simply printed a document and after that, the scanner was up and running again. Strange...

sounds like the clicking may be the high voltage trying to ignite the lamp. when it does come on the picture is very bad. Did the lamp seem to shine very brightly through the fan vent when it did come on that time when the picture was dim.
How many hours has the lamp been used for.
Check the air filter for dust etc.
See if you can borrow a spare lamp, and test it in the machine

I think it's capacitor issue on the power supply board. open it, look for power supply board and fine bloated capacitor and replace it.

Same problem here with IP4000. Power light comes on for a second and then dies. Let me know if you get a resolution.

1st try this....unplug tv...hold power button for 10 seconds...wait 2 minutes....plug back in, if this doesn't fix it you probably need to replace the lamp

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.

Ballast Verification Process
1. Short out door switch (SP001)
2. Apply AC power and wait till DM module boots
3. Press power switch and observe spark gap on ballast
4. If spark gap arcs, suspect Lamp. If color wheel starts but ballast won’t strike
lamp, go to next step.
5. Measure BP252 on AC IN CBA for +300Vdc. If missing check door switch, cable
from AC IN CBA to switch and AC IN PCB. If correct go to next step.
6. Monitor pin 2 of BT251 for Ballast ON command from Light Engine. If present
suspect Ballast. If missing suspect Light Engine. Pin 5 of BT251 starts at 3.3V
after power switch is pressed and drops to .18V when the Light Engine sends the
start command. No change on pin 5 indicates Light Engine is suspect, change
on pin 5 with no ballast start, ballast is suspect.

Note: Lamp may arc but not start. Pin 5 of BT251 is "LAMP LIT" and goes to 1.48V
when lamp is lit. If ballast strikes lamp but lamp won’t stay lit, suspect Lamp.

Have you cleaned the filters? In this situation, the fan and power shuts down even before the bulb lights up and heats up the unit, but perhaps the unit can detect clogged filters.

You can download the manual here if you don't have one. Instructions for cleaning the filters are on page 37.

yep

unplug the system
open the case
look for a battery and take it out
take out the memory (rams)
wait ten minutes
press power button 5 times
put everything back in

and boot it
