Question about Sanyo PLV-Z4 Multimedia Projectors

1 Answer

Projector question i have a projector, just got a new lamp for it since the other one burned out, and when we installed it, the projector immediately said that it needs a new bulb. It still shows a picture, but i am not sure if it is a problem with the projector or the the bulb. Is there a chip or something that has to be reset when a new bulb is put in?

Does not turn on all 4 lights lit up on face of unit

Most likely the lamp is burned out. Check the lamp and if it is bad, replace it (unplug projector while you replace the lamp). If it turns on, reset the lamp counter and you're all done!
Be sure to weigh the cost of the new lamp vs replacing this 6-8 year old projector!

How to change the bulb?

do the following steps to change the lamp of your projector.

1. Turn the power off and disconnect the projector from the wall socket.
2. Turn the projector over. Then loosen the screws and remove the lamp cover. If the lamp is hot, avoid burns by waiting for 45 minutes until the lamp has cooled.
3. Move the latch to another end as shown in the picture.

4. Loosen the screw that holds the lamp to the projector. If the screw is not loosened
completely, they could injure your fingers. It is strongly recommended that you use a
magnetic-head screwdriver.
5. Lift the handle so that it stands up. Use the handle to slowly pull the lamp out of the projector.

6. Insert a new lamp. Make sure the handle is fully locked, move the latch back, and
tighten the screw firmly.
7. Re-install the lamp cover and tighten the screw. Do not turn the power on with the lamp cover removed. Whenever the lamp is replaced, reset the total lamp operation time. Do not reset if the lamp is not replaced as this could cause damage.

8. Resetting the lamp counter
i. Press and hold the Exit 5 button on the projector for 5
seconds to display the total used lamp time.
ii. Press Auto on the projector or on the remote control to
reset the lamp hour to "0".
iii. Wait about 5 seconds to let the OSD disappear.

I have infocus LP120 and the bulb burned out the other day. I installed a new bulb and it starts up fine except there is burning smell from the vent. Is it normal? Some guys told me it's "burn-in" process...

Yes it is normal, but there were issues in the past with the lamp burning the lamp cables. Infocus then upgraded the cables with slightly heavier gauge wire and better thermal tape around the wires. It would be hard for me to tell you if yours has the upgrade, but if you got it from Infocus I'm sure it is good.

When turning it on, the lamp light starts to flash red, what should I do? The power green light also turns red and it won't do anything...

This means that the lamp is burned out, not installed properly or the lamp cover might not be closed. Try to reseat the lamp, make sure that you close the over properly. If that fails buy a new lamp.

NEC VT695 (not a vt570) bad lamp blowing ballast board?

We have the same model here at our school too. I know of two that have done exactly what you said. I am trying to figure out if this is NEC fault. Bulbs are expensive and if the projector and NEC is a fault; we will definitely be moving on to a different brand.
