SOURCE: PLV-Z1 no longer powering up - Ready light is green and the Lamp light is red

Hey zrscott388, did you end up replacing the bulb and did that fix it? My Z1 is doing the same thing. I hate to spend 300-400 on a bulb and it doesn't work. The Z5 is going for 1100 new on Ebay. I rather do that than waste money. Please let me know.

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.

In the on-screen menu...
Press MENU, go to SETTINGS ICON, Move to Lamp Reset

Also, to see lamp hours used, press and hold the UP ARROW (on the unit, not on the remote) for 30 seconds while projector is on.

check the physical nature of the lamp in the projector. around the filament of the lamp, you might notice dark corrosion building around it. this what normally cause premature shut off.

I have a model PLC-XT11 and when I turn the power on the temp light and green ready light begin to flash. The red lamp light is on steady. I replace the lamp but no luck.


one or more of the fans may not be working right. also, the temp sensor may be shot. if the last time you used it it wasn't shut down properly, it may still be in cool-down mode.

Sanyo plc-xt10a will not power up. ready light is not on. power to unit is good.


First, check the lamp/lamp door--the door has a safety interlock that prevents power from getting to the projector. Make sure the power *is* getting to the unit by using a known-good power cord. Also, check the 3 air filters. If one or more was clogged with dust, the unit might have had a thermal sensor trip. There is also an internal fuse on the power supply which may have blown.When was the last time the projector worked correctly? Have there ever been any power problems related to that unit before? If the above checks yield no success, the projector will have to be repaired at a service facility. Hope I was of some help---Rick

Sanyo PLC-XF46N projector shuts down before powering up completely


The Fix Ya rep suggested that I try the "Reset" button located next to the Audio out on the side of the projector; this solution proved to be the fix I needed. I was able to get the lamps to warm up and get into the menu to cut back the bulbs/power consumption on start-up, allowing the projector to function for a problem-free 4 hour period Unfortunately, I had the same issue this morning, but the same fix worked again.
