It might be installing an update. If you disconnected something while it was powering down - Internet, screen or something like that, it might have frozen.
Make sure you have power cable plugged in and the same with the internet (if you normally have one). If it stays the same way for more than 30 min. then you can hold down the power button until the pc turns off (5 seconds). Then wait 30 seconds, then turn it on again.

Sounds like you are caught in a Bootloop for some reaso. Press and hold the Power Button for 40 seconds, release. Then plug the device in a charger, let charge for 4 hours while powered down. Unplug the device from the charger:
Step1 : Press and hold the Power Button for 30 seconds, then release the power button.
Step 2: Press the power button for 1 second, release and press the power button again, release.
Step 3: Is the device booting normally? If no, contact the manufacture for a replacment.

Lamp is near end of life. Try reseting lamp timer and order new lamp if unit stays on

I had the same problem with the light black and light magenta as well. It took trying only one new cartridge with the light magenta before it worked.
The light black took 4 new cartridges before it worked. I had called the Epson support center on this problem and after going through suggestions they made that did not work, I told the guy I had another new cartridge on hand. He said to go ahead and try it. This time the printer worked. He took my name and address and said the other cartridges were faulty. Epson is sending me new replacement cartridges at no charge.

1. Make sure the unit is turned on, and not printing. The POWER light should be on, but not flashing.

2. Lower the OUTPUT tray, and lift the scanner portion to access the ink cartridges.

3. Press and release the INK button. The print heads will move to the left, and the cartridge that needs to be replaced will stop directly beneath the OUT OF INK symbol. Make a note of which cartridge requires replacement.

4. Press and release the INK button again. If more than one ink cartridge is empty, the next cartridge will move under the OUT OF INK symbol. If no other cartridges are out of ink, the print heads will now move to the REPLACEMENT POSITION.

5. Open the CARTRIDGE COVER. Pinch the front and back tabs of the empty cartridge as you lift it out of the unit. Dispose of this cartridge.

6. Before you remove the new cartridge from its package, shake it four or five times.

7. Remove the new cartridge from its package, and lower it into the cartridge holder. Push down gently until the cartridge clicks into place.

8. Repeat steps 5-7 for each cartridge that you need to replace. Close the CARTRIDGE COVER once all of the necessary ink cartridges are replaced.

9. Carefully lower the scanner, until it clicks into place

10. Press and release the INK button.

The ON light flashes and the printer makes noise. Charging takes about 30 seconds. When it's finished, the ON light stops flashing and stays on steady.
Caution: Never turn off the EPSON Stylus printer while the ON light is flashing, unless the Stylus printer hasn't moved or made noise for more than 5 minutes.
