My hitachi A120n projector has no power light checked internal fuse and ok .

SOURCE: hitachi projector temp light

This is what your projector's user manual says about a flashing "TEMP" light :

"The cooling fan is not operating. Turn the power OFF and wait approximately 20 minutes. After the main unit has cooled down, please make confirmation that no foreign matter has become caught in the fan, etc. After performing any needed maintenance, turn the power ON again; if the same display is displayed, then please contact a sales store or a service company."

Your user manual is available at the following link :

Yes, there is. If you go to searspartsdirect.com and type in your model number, you will find the fuse listed under the "Interior Parts" heading as item number 14 (part #815174). You can find appliance fuses much cheaper at the local hardware store. Just make sure it is the correct type and rating (refer to the fuse in the appliance for the information - these are usually a 120V 20A fuse). The reason I mention this site is because they provide excellent part drawings and provide part numbers. There should also be a wiring diagram located behind the control panel to assist you in troubleshooting. Please go to my profile and use the "Ask Me" feature if you require further assistance. I hope this helps you.

SOURCE: projector won't power up

i have the same problem, it seems like a fault with the psu

SOURCE: power (maybe internal fuse)

This sounds like either the power supply&Ballast is blown. Or the lamp blew out. Take the lamp out, look at the bulb to see if it is frasted heavily or just broken. If not you might want to send it in for repairs.

SOURCE: during play, entire unit went off and will not turn on. No lights, nothing

there is a bimetal circuit breaker on the lamp housing that will cut the power if it gets too hot. it needs to be reset, but you have to remove the top to get to it.
