Get a hole cutter 2~3" drill holes in the back of the cabnet(looks better). Look at your TV and find out where the air goes in and out. At the back of the cabnet near the shelf where the TV sits drill a couple of holes, at the the top of the cabnet above the lower holes drill 2 or 3 more hloes. This will alow cool air in at the bottom and hot air out at the top. John
I recently purchased a new Sony 50 inch HD LCD. It just fits into my built in cabinet. The cabinet is not open in the back. Should I be comcerned about venting the TV? I know there is a lamp and a fan. Should I drill holes in the side of cabinet?
