I have a vivitek 5080 projector the lamp comes on but doesn't recognize anything plugged into hdmi slots,what can I do to fix it?

SOURCE: Mitsubishi xl2u projector

I ended up sending it to Mitsubishi Service center for repair. The technician said it was the power supply and it now works so I'm happy.

SOURCE: Have replaced projector bulb,can not reset lamptimer

turn the tv ON: On the side of the TV press the menu and volume up buttons at the same time for three seconds. The 'reset lamp timer?' will appear on the screen. Press the OK button to accept. You're done!

SOURCE: Projector powers up as normal, bulb comes on,

There is a source lock and source button I would unlock source lock button and the push source button until you get to your hdmi input you are using. You also may just plug in one input first and once you get the input right play with the multiple hdmis

SOURCE: my vivitek d510 projector lamp is not turn on.

You need to check the power supply feed to the lamp circuit and if this is workingg fine check if there is lamp reset- hours used. Also if the filter is blocked remove and clean, check the fan and also the connections/connectors in the mother board.
If not there can be errors in the motherboard.

SOURCE: my projector won't project anything.

I have the same proble with my CP-S318 Hitachi except ut does show the logo but will not detect any connection.
