Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television
We replaced the Projection Lamp and now we don't have video or volume.
Pull the lamp out and with a flashlight look at back of the compartment. There should be a cutoff contact switch at the bottom where the lamp pushes it inward when connected. If you dont see this, it is possible you may have inadvertently pushed to hard when inserting the lamp and that switch has to be replaced. It is part of the projection engine/unit and unfortunately that will be expensive if that is the issue. Good Luck

I bought a True replacement from the PartsStore through Amazon.com and it cost me about $185, but it was a Phillips bulb and the full cartridge replacement. I went with the aftermarket bulb only replacement the first time, lasted less than a week and haven't resolved that issue yet.

SOURCE: Replacement lamp
does the TV still turn on? you should get between 3000-6000 hours of life out of your lamp. You can pull the lamp out and see if there is any discoloration in the center, if there is then it might be a good idea to do a little preventative maintenance and replace it.

You can by the lamp online from various outlets. They usually run around $150 to $200 and are pretty easy to install at the back of the television. Make sure the TV is unplugged and use a screwdriver to remove the outer cover and loosen the lamp housing. Disconnect the connector and install the new lamp. Re-install the screws. take special care not to touch the lamp because your skin oils can cause the lamp to fail. Make sure you go into the menu for the televison when your done and rest the lamp timer.
Here is a link to a web-site that sells lamps. Definently shop around prices can very greatly.
