I have a Sanyo plc-xt25 LCD Projector and when I plug my ac cord in, the fans turn on but no lamp comes on. I changed the lamp and still no picture. What do I do?


Every projector lamp is equipped with ballast. The problem area is ballast. Either the ballast is not getting DC supply or the lamp turn ON signal from the projector main board or the ballast is faulty. Remove the lamp. Connect the projector to the mains supply. Check the voltage at the lamp connector inside the projector without turning it ON. It should be around 65 volts A/C. (Warning: Multimeter will get damaged if the projector power is turned ON due to generation of high voltage) If you find this 65 volts then it confirms that it has DC supply & the ballast is functioning. The ballast receives the the turn ON signal from microcontroller through opto-coupler on the ballast. The ballast opto-coupler can be checked by providing external 5V DC supply between pin 3 (+ve) & 4 (-ve) in turn switches ON the lamp. If this works then there is no problem with your lamp & ballast. The problem lies with the main board. If this does not solve your problem then give me the feedback.

The countdown shows while the unit is going through its internal circuit testing. Usually if a problem is found, there will be indications with the standby lights and lamp/temp lights. Are there any other indications here or just the unit going into standby?

How to check lamp hours on xf-45 or xf-35?


On the XF-45, you push the "UP" button and then the "Menu" button and hold both of them for approximately 20 seconds. After that you will see a bunch of numbers in the top left hand corner of the screen. Using the Left and Right arrow keys, move the "Group" number until it reads 111. Then using the Up and Down arrow keys to scroll through each lamp (0-3).

If you move the "Group" number to 110, you can see total number of hours that socket has run.

Sounds like a simple problem to fix but don't ask here unless you plan on signing up...take your projector to a "real" professional who'll actually speak to you.
