We decided to purchase an LED TV for the bedroom. The old TV was a Prima tube type TV/DVD combo. Obviously, the new TV wouldn't cover the entire hole, so Kat & I went to Home Depot and purchased about 3' of poplar and some stain to match our existing cabinetry and set out to modify our bedroom cabinet (Kat also wanted the extra storage space behind the TV!)
We went garage selling today and purchased the piece of glass for a buck. The hardware I had, but did purchase a piece of A/C filter cloth like we have on our air conditioners for the back of the cabinet.
Total cost was less than a Jackson.
