Lamp door is securely shut on KDF50E2000 50 inch DLP Sony Wega. Unit turns on for several minutes and then shuts off and blinks 3 red lights

SOURCE: Sony Wega Tv powers on w/ green power light and

need to know how many time the red light is blinking there should be a pause. 4 blinks is a fan, 3 blinks is the lamp door is not closed 6 blinks is thermal sensor.

SOURCE: i just installed a projection lamp in my sony wega

Check the lamp door. It may also have a bad thermal fuse.

3 BLINKS SHOULD mean lamp door not properly closed.

If you look carefully at the lamp door --is it warped? Look at it edgewise--if it is bowed at all it is the problem.

Heat gets it from the lamp.

Here is a way to prove this for yourself--the door has a plastic peg on the back--when it is in place the peg engages a small lever--usually blue in color and you can see it with the door removed.

It is there to prevent the set from being operated with the door removed.

What I suggest you do is with the door removed engage the lever with something NOT METAL a plastic piece or even a match stick--with the lever pushed forward (which is what the peg should do) turn the set on.

If it comes on and works you just need to replace the door--very common on this set.

Let me know if the set works this way--DO NOT LOOK AT THE LAMP WITH THE DOOR REMOVED AS IT CAN DAMAGE YOUR EYES.

IF the set works this way confirm the model number to me--Usually there are at least 3 sellers on EBAY selling OEM doors for this set at about 20 including shipping--Sony will have them for less but often are out of stock because this is a common problem.

3 blinks is the lamp door error code. Try jumpering the door switch. These switches are notorious for going bad.
