Sony kdf42we655 red light blinking lamp

If you have changed a spark plug in a car--this is EASY to do. The lamp is behind the front panel in this set IIRC. That bottom piece comes off, after removal of the "thumb screws" on each side of it on the rear. It then takes some effort to "pop" the catches loose, but it will come off, just work from one side at a time. Then, the lamp door is in the middle and a big thumbscrew holds it on. Remove it, and the lamp is behind here, up a small "tunnel" and you will need an allen wrench to remove the screws holding it on. Once this is done, it pulls out--and can be replaced with a sony lamp, I think an XL 2100 or XL-2200. BTW a new Sony lamp WILL come with an allen wrench.
