Where is the lamp located in a sony rear projection 52 inch tv?

unplug the tv for about 5 minutes then plug it back in

LAMP pull it out and see if it looks busted on the inside.

I've had this problem with my projection TV recently. I would say your lens/lamp is to blame. It might be time to change it, depends on the last time it was changed, most of the time, the TV will tell you that it needs to be changed, but not always. I think your best bet is the TV lamp.

Call Mitsubishi the chassis needs to be rebuilt on this set they have been paying for the parts but you will have to pay the labor.

remove the two small covers left and right behind the front lower panel.remove front lower panel (its a firm fit) pull in this sequence 1 rht top, 2 left top, 3&4 lower mid. lamp behind a panel just to the left of cantre, remove two screws locating it in place .pull lamp housing out

take off the speaker grill. next to the left speaker will be a door with like 2 or 3 screws holding it closed. take those out and your lamp is in there held in with 3 screws. unscrew the lamp put in the new one and just reverse.

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

You have a bad lamp. Order a new one (an original Sony, not the crappy aftermarket replacements) and follow the instructions in your owners manul for replacing the lamp.

If my tv goes out and the Lamp light comes on what does that mean

you have a bad lamp or balast
