Zarak,
You've got me a little concerned since the plans for my cab didn't include that much space around the tv. I just checked out the owners manual on the A3000 and it doesn't list the clearances that you mentioned. It just said "To prevent internal heat buildup, do not block the ventillation openings." Where did you see the clearances that you had for the A2000? The manual does say the tv has internal cooling fans that may be heard during operation, is it possible the A2000 didn't have fans and heat was more of an issue?
Thanks
