So will anyone offer a solution or possible prediction on the defective component?

Anyone?...

At the left corner you will find a small piece of black tape. Remove that. 

Behind that tape you will find the standby led from the panel. 

When switching on the BV5, the led turns from red to green and the same time, the panel is powered on. 

At thia moment there has to be a visible green or red led next to the buttons on the pana panel. 

 Check at the bottom corner that the mains switch is switched on. 

The panasonic panel is on yes.

Does anyone know what could possibly be the faulty component?

Could be as simple as a fuse at the powerswitch board, located in the middle at the bottom. Or a failing panel. So, further investigating is needed. 

I feel quite certain that it is the Panasonic panel that is failing.  I am trying to remove it however it is held in place via the bracket attached to the lower section, which appears almost inaccessible.  I have removed almost every available screw, but nothing will budge.  I'm sure it has be made this way to prevent tinkering,but how am I suppose to diagnose it properly without removing the components?  Does anyone have diagrams?

The complete service manual is on the main site. Just upgrade your membership for access.

It's rather easy. 

4 screws at the back, hidden behind a plastic cap. 

After that just 2 screws  on both left and right side, loosen with an Allen Key. The panel then comes down.
