Yes you can get to it. take apart the calm shell case, remove the back metal protector over the circit boards, remove the boards, remove the metal shroud holding the lcd panel to the back lite. Discard all that tape, you dont need it. remove lcd from backlite, clean back of lcd panel and front of back lite panel.
While you are in there replace the 2-5 caps on the secondary side of the power supply, often 470uf 25v or so. (sometimes 820uf) get good ones. Panasonic cf series are very good, low esr electolitical caps.
