Power (maybe internal fuse)

Projector won't power on. no lights light up, nothing. projector was running, then someone running a microwave tripped the breaker. flipped the breaker back on and the projector will not turn on.

email from eiki said it was probably an internal fuse.

is there a way to check/fix this myself?

    I'm looking for the location of the int. fuse?

  • Christian Ramsvik Nov 29, 2008

    I don't know if any breakers were tripped or anything, but kI know the projector was used last weekend. Today, noe week laker it's just "dead". I am going to open it as soon as I get some torx screwdrivers (bits won't fit in the holes) and see if there is any visible damage, or perhaps an internal fuse.

    I had this on a Sony VPL CS4. I think it fried one of the chips inside the projector.

Hi
if power is not on means definately problem occur in power supply board. In that board 1st check fuse(it may be cape fuse ),thermister, diode and capacitor in multimeter.
suppose all are in very good condition 2nd thing to check the transformer secondary side filter capacitor voltage.wheater low voltage come across to that means also cause the projector not on.

This sounds like either the power supply&Ballast is blown. Or the lamp blew out. Take the lamp out, look at the bulb to see if it is frasted heavily or just broken. If not you might want to send it in for repairs.

NO power, no lights, possibly there was a flash before it went of


The internal fuse is normally located very near the power plug socket and usually a Buss glass fuse, rated 5 amps? If you get to it, check the metal end for the rating.You have to remove the top cover to get at it...remember, the problem could be the fuse--or the power supply section has failed.--Rick

Projector not working


Have you tried the internal fuse? without a proper fuse in the panel you will get no power i.e. lights and such to the device. Simple but the first place to check.

HP VP6210 won´t turn on at all


try to replace all the capacitors on the motherboard. This are the only parts that leak in time. Try otherwise to reset to counter or update the firmware on your machine on the infocus site.
Goodluck !

Infocus LP-820 no power


You should get some indication of power even without the globe. This can however be a problem relating to the globe not being inside the projector.
Most projectors use a switch inside so they know when a lamp is installed. Some have several of these and a fuse that is on the lamp unit itself.

Replace the lamp back into the projector and apply power again. If you get lights then you have that much solved at least.

If there are still no power lights at all, then you may have had a power surge that not only killed the globe, but has blown the internal fuse for the power supply as well (or even killed the power supply)
To get access to the power supply you will need to disassemble the whole unit almost. If your not comfortable doing this, then I would advise getting it checked over by your local tech. It could save you hundreds of dollars buying a new lamp when the projector may not be worth repairing.

Projector will not power on


body { background: #FFFFFF; margin: 0px; padding: 4px; font-family: arial, verdana, sans-serif; font-size: 10pt; } p { margin:0px; padding:0px; } .spwrap { background: transparent url(../wysiwyg_rte/misspell.gif) repeat-x scroll center bottom; } If you can, confirm the output of the power source! if you have +/- 0V on all outputs then you may have a defective schottky, verify if all 4 diodes on the secondary are ok ( you can spot a bad one by the short circuit on the 2 terminals).
The power supply of the lp640 has a protection derived by the functions of TOP 2XX witch in overload stops. therefore disabling the shorted output.
Verify the state of the fuses also.

Good luck out there ,
