Our 5 year old 32" LCD in the bedroom finally died.  My wife suspects I helped it along, but I had nothing to do with its demise Posted Image.  I wasted no time picking up a Panasonic 42" GT25 3D plasma on sale at Costco.  I knew I wanted a plasma but wasn't initially planning on 3D.  The sale price combined with the fact that I already have a Panasonic 65" VT25 and several pair of glasses in the game room made it an easy decision.

The only problem is our AVR is a 3 year old Denon 3808 that doesn't pass through 3D video signals so I got Blu-ray player with dual HDMI outputs (one for audio to the Denon and one for video to the TV).  This required that I run a second HDMI cable to the TV.  Not an easy task considering that the TV is in the middle of the room at the foot of the bed and the receiver and Blu-ray player are in the closet.  I thought about going with a wireless HDMI solution, but those are rather expensive and a 40ft Tartan HDMI cable was only $28 at Blue Jeans Cable.  Thankfully my friend John owns a custom installation company (Elite Audio/Video Inc.) and he agreed to help me out.  John had previously run the first HDMI cable to the TV after the DVI cable we installed during construction went bad.



Audio Gear from top to bottom: Panamax surge protector, Triad subwoofer amp, Crestron relay controls for blinds, RS232 and power sensing modules for control of equipment in rack, Denon AVR-3808 receiver, Denon 3910 DVD player, Toshiba HD-A2 HD DVD player, Panasonic DMP-BDT300 dual HDMI output Blu-ray player, Linksys Windows Media Extender (will be replaced by the XBOX below it):


The cables for the master bedroom TV come out into the room under the bed.  We moved the mattress and box spring out of the way, and pulled all the unused cables out from under the floor.  We picked an audio cable that was never used to act as a pull rope.  We taped the new HDMI cable to it with electrical tape and "lubricated" it with dish soap.  The new HDMI cable is the black cable going from the hole in the floor to the bottom of the picture:


Unfortunately the joists run the "wrong" way so instead of going through one long open bay, we had to go through multiple joists.  There is a finished basement underneath so John got creative.  In the room below he removed a ceiling speaker which gave him access to the cable.  The white wires are electrical and a speaker wire.  The cables going to the TV are about two feet over in the hole, not shown in this picture:


That got us through several joists.  Next we cut an access hole in the ceiling.  It won't be that noticeable as it is in a closet and a spot where the drywall went from two to one layers because of a fire sprinkler (orange pipe).  The white pipe is vacuum, the wires on the right are for the theater, the wires on the bottom are the ones running to the TV that we want to add our HDMI cable to.  The white wood is blocking to allow us to reattach the drywall:


John pulling the cable:


We then had to feed the cables up through the floor.  We wheeled the audio rack out of the way to get to the wiring.  The wire coming down the wall actually looks more organized in person.  Its coming from the TV in the master, a TV location in the master bath, and the in-ceiling speakers in the master bedroom.  The single cable coming from the left is the initial retrofit HDMI cable that was previously installed using the access hole cut into the wall.  The white panel on the floor is what hides the opening.  Its been removed for the cable install:


We pulled the cable up through the floor and up through the wall where the first HDMI cable comes out.  We put the panel back on the wall and rolled the rack back into place.  Its hard to tell that we had the wall open with the spring loaded access panel John installed in place:


We then used Velcro straps to bundle the two HDMI cables, a network cable, IR cable and RG6 cable together and put all the unneeded cables back into the floor closing the lid:


All that was left was to put the mattress back, reinstall the ceiling speaker in the room below and screw the drywall panel back up.  I'll use white painters caulk to cover the seam in the ceiling.

Here is the finished product.  The cables come out of the floor under the bed through the cabinet and into the back of the TV:


We are now 3D capable and wife approved!
