I had the same problem with a "Sony VPL-ES3" projector. The lamp cover light would flash and the projector wouldn't turn on.
I think its a problem with a filter cover. This fixed the problem for me: 

  1. Plug out the projector
  2. Click off the filter at the bottom of the projector.
  3. Plug the projector back in. (the lamp cover light should flash)
  4. Plug the projector out again.
  5. Put the filter cover back on.
  6. Plug the projector in again and it should work fine.
This has worked for me every time I have had this problem.

I encountered the same problem and solved it following ranjum's solution: Tighten the screws inside the lamp cover at the project bottom.

Thanks podge for your solution. I had tried it before as suggested in VPL-ES3 reference book (trouble shooting section) but it has not worked for me. Instead I have foud that there is a lamp cover at the bottom of the projector for replacing fused lamp. This cover is tied to the bottom via a single screw. Just make sure that this screw is not loose. In my case, when I tightened it the indication has vanished.

Take the lamp cover back off. Check the mechanism that the projector uses to sense the door. It might be a small pressure switch. Check whatever triggers the mechanisms is still attached to the door and hasn't broken off.

Status light is blinking red, power button orange nec vt700

Look at the number of blinks of the status light.
[1] If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.
[2] If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.
[5] If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.

Replace the 2 bulbs. Unit powered up correctly and turned on like normal. Then Lamp1 and Lamp 2 indicator lights blinked (Indicating Start UP). After some period of time, it switched to Red 6 times blink...

1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.
i have nothing on 6 ligths go ahead reconect and check for proper count. hope this information helps.
Best of Luck.

I have changed the lamp in a Sony VPL EX-1. I have fitted a YODN (LMP - C150) I cannot get the flashing light to go out which indicates `lamp,cover` and I cannot do anything with the projector.

When you open the lamp cover for replacement of lamp there is a switch in the projector is OFF
If lamp cover not fix proper after replacement of lamp the lamp/cover indicator flashing
SOLUTION: Open the lamp cover and fix proper and tight the screw

The power light is red, and the lamp light is blinking red. can you help me. thankyou

This indicates that the lamp cover is not properly closed. Disconnect the mains power and carefully open the lamp cover, reseat the lamp and close the lamp cover taking care not to force it.

A fault of this type would be common after a lamp has been replaced, or at least removed for inspection.

NEC VT 595 wont turn on. Just red blinking light

I had this same problem with 2 NEC VT595 projectors. My problem was that there was a broken "tab" on the lamp cover (the plastic cover that slides in place over the lamp) that is supposed to depress a switch which insures the lamp cover is in place before operating the projector. The tab was broken in half and not making the connection there for causing the blinking status light (.5 sec on, 2.5 sec off) indicating a lamp housing or cover error.

Can't on

The service manual states that a blinking lamp indicator means the lamp cover is not attached securely or the air filter is not inserted properly. You may try removing both and re-attaching to see if this clears up the problem.
