Sanyo PLC XU105 Will shut down in 10 to 15 seconds

1,Check the fans ,whether the fan is running,when you turn on the projector
2,if the fans run, then ,check the lamp or lamp ballast

The uProcessor thinks that it has overheated and is frantically trying to cool down what it thinks is a hot lamp.
This condition has many causes from an exhausted lamp to lamp ballast fault or even a power supply fault or a heat sensor/fan fault.

It sounds like the lamp is going.
Do you know how many hours of use are reported on the lamp?

Many times these projectors have circuitry to shutdown when they suspect the lamp is near the end of life. Lamp hours vary and usually will go up to and even beyond expectancy, but there is occasions you can receive a bad lamp and have it blow in a matter of hours...not common but it does occur.

I hope this helps,

SAYA MEMPUNYAI SANYO PLC XU105 , JIKA DIHIDUPKAN POWER LAMP MENYALA HIJAU BEBERAPA DETIK KEMUDIAN LAMPU WARNING LAMP MENYALA, KIRA KIRA KERUSAKANNYA DIMANA YA..? TOLONG YA SOLUSINYA..THKX

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.

You have a classic temp sensor problem. Its a fail safe on theprojector, basically a fuse that bridges the main power cables. Lookslike a little pot, With a white ceramic head.
Now what it does, Is the white ceramic head rises as the unit getshotter, and thus breaks the power circut. All you need to do is, openup the unit, locate the sensor (its mounted next to the lamp on yourprojector) And push the little white head back down, thus closing thecircut, and restoring power supply.
Here is the full repair schematic to guide you. :)

check the follwoing :
check lamp physically for melted filament, white deposits on filament/ reflector, if so change lamp
if lamp looks perfect, the ballast needs to be replaced, also check for fans if they are running fine

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.

theres prob something wrong wif the bulb
