I am in the process of switching out cracked LCD on my TR3A. I undid 4 corner screws and the 2 at the bottom, still it appears something is hoding the bezel at the top (approximately an inch toward the motion eye panel) on either size - are there some additional screws somewhere in that area?? I am not sure if I need to use some additional force or I am not doing something right. Can someone please point me to some directions on this site or provide some guidance on the matter? Thanks.
