Oak Desk with Embedded TV/Monitor part 3 : Fitting the TV

This is a continuation of my build of an oak and glass desk with a 32" TV & computer built into it. The previous parts of the build can be found below.
Step 5: Fitting the TV

The TV that was volunteered for the project is a Samsung 32" LCD.

Removing the bezel revealed the actual dimensions of the panel and the frame which would need to be incorporated into the desk. To allow this whilst keeping the panel near to the glass I had to rout a border into the underside of the desktop - as mentioned in part 2.

Fortunately the frame of the TV included mounting holes. Less fortunately, they were in line with the thinner ledge that held the glass. It didn't seem wise to mount screw the TV to that thin ledge - it had enough weight to support with the glass alone, therefore I created small plywood mounts to go between the TVs mounting holes and the main body of the desktop.

In order to protect the user and the electronics from each other, I decided to keep the plastic back of the TV. This was simply held in place by several "mechanical retention blocks" (a fancy name for small offcuts of wood that wedged the back in place). This held the back securely, while also allowing access should it be required for maintenance/upgrades.

Step 6: Fitting the CHIP

Rather than have cables trailing to the TV from an input device, I decided to add a small single-board computer. The system I've opted for is the CHIP - a $9 dollar board. I backed their Kickstarter for a couple of CHIP systems and a VGA adapter board. The spare CHIP will surely find it's way to another project, but one of them and the VGA board are being used here.

After setting up the board and configuring it using a spare monitor, it was time to transfer it to the TV. I removed the back of the TV, and sat the CHIP there - there was sufficient space for the board, but I had to cut out a bit of plastic for the cables to run through (the VGA cable into the back of the TV, the power, which went to a phone charger in the desk's extension lead, and a USB extension lead which just runs out to the back of the TV so that I could connect peripherals if needed.)

Once the back was replaced on the TV, there's not really much to indicate it's anything more than a standard TV.

The next (and hopefully final step) will be to get some software on there.
