Question about Sanyo PLC-XP55L Multimedia Projector

Sanyo PLC-XP55 "new" both temp and ready lights flash

The unit is near new, less than 50 hours on the lamp. I bought it on Ebay from a reputable dealer as a working demo tested but no warranty. It starts normally when the power button is pressed but as soon as the lamp strikes a few seconds later the temp and ready lights both flash the fan slows and it goes into a "locked standby" mode. Page 42 of the manual advises to remove power and try again but if it happens again "the internal check and service will be required".

Any checks I can do to solve the problem or have I bought an expensive lemon in need of a major repair?

One of the common problems on this and the 56 model is the exhaust cooling fan, the reason being that due to the heat given off from the lamp assembly the bearings dry up, even if they dont fail but go stiff, this also causes problems because inside the fan it is fitted like most of them now with a rotataion speed sensor and the system control monitors the pulse reference.If this changes and is not upto speed to keep the lamp cool enough the internal heat sensor detects this and the unit locks up into protection mode to protect the lamp assembly from getting too hot or even exploding.Kind regards John Williams www.jvsvisual.com

Hi

When it flashes, how many seconds is the interval? If its one-sec interval chances are you are having a hardware issue with the projector. You can clean the filter/exhaust of the projector and the other option is try to reseat/remove and reinstall the lamp of the projector.

Hope this helps

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-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.
