Zenith E44W46LCD Video Problem

My Zenith E44W46LCD rear projection LCD no longer shows any video through any of the inputs, but the audio works fine. TV is approximately 5 yrs. old, and I have already replaced the bulb about 4 months ago. The only indication I get is a "box" that floats around the screen with "No Signal" as text within the box. I posted this issue on another site but all I received back is, "Check the Tuner Board Fuse". I've checked the Service Manual (and the user manual) for this set and can not find any reference to a replaceable fuse. I have not had the opportunity to check all of the circuit board schematics yet. Replacing the bulb was not a problem, but I have concerns about taking the entire set apart to get at the tuner board to look for a fuse. If anyone has any insight I would appreciate it.
Thank You,

Your only hope is that the problem is on the power supply board.Everything else is no longer available or not going to be the problem.
