I have a Sony LCD Projection TV and it will not turn on .

Customer Question

I have a Sony LCD Projection TV and it will not turn "on". The green light which indicates when it is "on" just keeps flashing...I am not sure if something was pushed accidentally and I can't figure out what is going on. Thank's for your help.

Normally if the green light keeps flashing when you turn it on, and doesn't stop it means the lamp won't light up at all.


And it will normally shut off and the red LAMP light will display.....


However, I have had INTERMITTANT lamps that light up, but won't hold the Arc when it switches from Strike mode to Run mode. These are notorious for causing the TV to just keep blinking, and when you pull the lamp out to inspect it, the lamp might look ok to you.


If you have had the TV set for 3 years, the lamp is pretty close to being bad anyways.


Pull the lamp out and inspect it, if you see anything unusual like the ball at the bottom of the lamp is white or bulged, that's a clear cut indicator of a bulb that's ready to die.



If you give me the model number of your TV set, I can look up the part number for your lamp.

The model #KF50WE610 Where is the lamp located in the TV? Is it in a place easy to replace?
Expert:  TV Tech1 replied 7 years ago.

Yes, it is easy to replace, and I'll get the part number and some install information to assist you.


The lamp part number is A-1606-034-A, also known as an XL-2100 lamp.


To get to the lamp, you remove the lower panel below the screen, there are 2 ornamental screws found on the back edge. Here is a picture of the lower panel removal.




The yellow area is where you'll find another door for the lamp, unscrew the ornamental screw on that, and pull the door off, then get an allen wrench to remove the lamp inside.


Look at it. If you see a milky white deposit on the glass or the glass ball at the bottom is milky or bulged -- that lamp is definitely bad. Now if it looks good and clear and shiny, then re-insert that lamp. There is a hole in the plastic, just on the left side of the lamp, and you'll see a silver piece of metal showing, that's the lamp door switch. Push it down, hold it, and turn the TV on and keep holding it.


Now watch how the lamp behaves.....A GOOD lamp will light up and stay lit for over 2 minutes and not go out.


A bad lamp will light up.....go out.....light up.....go out....light up etc.


That is an intermittant lamp. Keep that in mind if you think the lamp is ok.


Here are some websites to purchase the lamp at...I suggest getting the lamp WITH the housing.

This one may not have the housing, call them to verify.

The first two reviews are very helpful, especially with removing the front panel -- yes it is scary the first time, but I've never broken it and I've been doing it for at least 5 years.



If you have any questions, just ask
