Projector does not turn ON

From the manual:

Press the (ON/STANDBY) switch to turn on the projector. If
the power is not turned on, disconnect the AC power cord, then
confirm the ON/STANDBY lamp is turned off. After about 10
seconds, reconnect the AC power cord and turn on the power
again. If the indicators still light up, the electrical system has a
problem. Consult with qualified Sony personnel.

Have reset the lamp hours after installing the new lamp? If, not the projector has treated the new lamp as old lamp & refusing to light further. So, reset the lamp hours to zero. To reset the lamp timer do as follows. Plug the power cord into the AC socket of the projector. Switch ON the power of the socket. (not projector) While pressing simultaneously INPUT, ENTER & UNDO on the projector, press ON on the projector. "LAMP 100%" is displayed, indicating that the lamp timer is reset.
If this does not correct your problem then the problem lies in other area. Let me know so that further I can provide you solution. Above things are preliminary

Hello
If the Lamp light and power lights are blinking orange, the lamp driver has failed, and the projector will automatically shut down. Unplug the power cord from AC mains wall socket, wait for three minutes and replug and see whether it helos you. If not, contact Dell service center.
OK.

Do you hear the fan start up? or does the projector lamp come on (you start to see an image)?

If yes to either:

When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down
to protect the inside of the projector. The POWER indicator
is blinking while the projector is being cooled down. When
the projector has cooled down sufficiently (to its normal
operating temperature), it can be turned on again by
pressing the POWER ON-OFF button.

Note:
After the temperature inside the projector returns to normal, the
WARNING indicator still continues to blink. When the projector is
turned on again, the WARNING indicator stops blinking.

Then check the matters below:
– Did you provide appropriate space for the projector to be
ventilated? Check the installing condition to see if
ventilation slots are not blocked.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of airconditioning
equipment.
– Are the air filters clean? Clean the air filters periodically. Let me know if you need to know how to do this.

If no to either:

When the projector detects an abnormal condition, it is
automatically shut down to protect the inside and the
WARNING indicator will be red. In this case, disconnect the
AC power cord and reconnect it, and then turn the projector
on once again for check. If the projector cannot be turned
on and the WARNING indicator emits a red light, disconnect
the AC power cord and contact the service station for check
and repair.

Please let me know if this helped solve the problem. If not, is there anything else you observed - whether or not you believe it's relevant.

A couple of things...

If the fan is not working, the lamp will not fire. If you have the owner's manual, it should indicate what the flashing lights mean. Check to make sure that the panels are seated properly. When you replaced the lamp, the outer cover was removed. If that is not seated back 100%, the unit will not work. There are a number of safety "checks" built into the unit to prevent damage and possibly fire as the lamps get really hot.

Check the items above and let us know your progress.

This works on a couple different Toshiba models -- might work on yours...

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "INPUT" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.
