Power light flashes green likes it turning on then flashes red 3 times. I just replaced lamp Sony Grand Wega KDF-55E2000

I see this so much that I am going to compose and save this answer:

3 blinks (it is in the owner manual) is "Lamp door not properly closed".

What is really wrong is if you remove the door and look edgewise it will likely be warped from the heat from the lamp.

1. On most of these but not all SONY knows of this and offers on many models to repair or replace the set for free---some models the heat also warps the area the lamp inserts in.

2. If you look at the back of the door there is a small plastic peg--it when door is installed engages a lever (small and designed to prevent the set from being used if door is open).

3. The way to prove if door is the problem is to with something not metal engage and hold the lever where the peg goes (you will have door off and also the large front plate giving access to lamp) and turning set on.

IF SET COMES ON AND WORKS DO NOT LOOK AT THE LIGHT FROM THE LAMP as it can damage your vision.

DO NOT OPERATE SET FOR A PROLONGED TIME WITH DOOR REMOVED OR THE FRONT PLATE (that covers access to lamp) attached as the heat with door removed can damage the outer plate.

4. If set works then you have a few choices=Google the model number with "lamp door" or order it from Sony and replace it.
