20 Most Recent Sanyo PLV-Z4 Multimedia Projectors Questions & Answers

I had the same problem. There is an internal reset button just above the lamp that needs to be reset. You have to take the cover off, which would void your warrantee, but it's quite easy. My lamp only had 660 hrs, and I bought a new one too. So now I have an extra. My guess is that my filter was getting clogged causing an overheating situation and tripping this reset button which I'm guessing is a heat sensor.

Had problems with image processor on this model

Just had the same problem. Based on other suggestions on here I tried resetting the overheat switch, and IT WORKED!

So, you have to pull the 6 screws (one of them is shorter than the rest, remember where it goes) that hold the top on the projector. 3 are on the back, 3 on the bottom - look for the arrows next to the screws.

Put the projector on it's feet, and pull off the top. The button wires will still be connected, so just hold onto the top and find the black circle/shaft above where the lamp is. The shaft has white paint on the top/tip of it. Push it down with a light amount of force. You should hear/feel it click.

Put top back on, put screws in, and you should be good to go.

Don't forget to reset the lamp replacement counter in the menus.

SORRY KIM,no idea about projectors

There is a lens/lamp filter which must be taken out and cleaned, use good air jet to blow and brush out dirt. If the filter is clogged then the lamp might heat up and so shut down..
if the fault does not clean try and force cool the unit, if not there is fault in the power supply, possible lamp problem or circuit error on load or heat.
You will need to open and use a test bench to check out the sections, one by one, use of multimeter and good equipments may be needed . If not take help with consensus.

the wires are shorting out in the power cord, replace it asap!
