No pic (no light of any sort) when turn on. Set makes the noise that accompanies being turned on and the front red light beside the power button lights up. But that is it. No sound or other indications that the set is on.
All the TV's have a fail safe now a days. It looks like that there is a problem with color management or the picture tube. If this is a projection than I could have said that it is a certain that it is to do with the color management. When Tv tries turn on it get a signal that there is a problem when it does the diagnosis prior to turning on and it stops. I am leaning towards the Picture tube as you didn't mention that the power light goes off after it tries to turn on. Please get it checked. good luck.

From the info you gave, it does sound like the lamp is bad. The sound you hear is the ballast trying to ignite what used to be a lamp. The lamp is assessable throught a 6x6 cover usually in the rear of the set held on by usually two screws. After the cover is off ( with a flashlight ) locate the screws(2) that hold the lamp housing in, remove those and it should slide out. Make sure you unplug the set first and remember to reset the lamp timer witch is located in your owners booklet after your done with the set on.
was the lamp blown if it was blown you could be hearing the ballast
if the lamp was not blown and the new one did not fix it the red light indicates the door there is a little switch when you put the door back on if you look at it it may need to be adjusted so it will connect with the door if that is not it you could have a fan that is not turn if it is making a real loud constant humming noise while it trying to fire the lamp you probably have a bad color wheel
According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.
You have no high voltage, like many in this forum, this model of Philips has some of the same problems. Look around here you may find the answer to your set. If not check Vertical IC, TDA8177, audio ic on signal board up front on left. check Power supply first for blown fuse, 1000, 2004, 1300, 1900 etc. No sound or pic means something is open. Does set has L E D lights on front of set?
