Thanks for the replies. My Beo5 is a little old for replacement and when I noticed that the dealer's suffered from similar symptoms I figured it was somewhat status quo.
I did however manage to remedy the problem quite easily.
The clicking/squeeking originates from the plastic shell surrounding the back part of the screen where the two halves snap together. Due to the type of plastic used, handling of the remote creates a certain amount torquing which creates friction where the two halves meet. The solution is simply to use a small amount of plastic-safe grease (as used in electronics at friction points ) brushed along both sides of the rim of the 'male' half of the case which inserts into the 'female' half. This is obviously only applied to the rim of the shell that will be inserted within the female part of the case and not any exterior part. Reassembly is straight forward taking care not to damage the cable from the Monitor when feeding/reattaching the cable into the slot on the main circuit-board in the base.
WARNING
This fix requires complete disassembly of the unit. Although the service guide offers good instructions, it does not address the specifics to removing the back off the screen which is required to perform the service. For this reason I am hesitant to recommend this fix as it would be very easy to damage the plastic functionally and cosmetically if one were to incorrectly "pry" off the back of the monitor. I'm also unaware of the "proper technique" for this aspect of the disassmbly to the degree that I would be willing to offer advice on a public forum.
However, due to the fact that many units suffer from the Squeek/Click problem and the ease in which it was remedied, I feel it proper to share with the group.
I certainly have more respect for the engineering of the beo5, apart from this particular design flaw, as the interior is very clean and well thought out.
