So I bought some sheets of MDF and basswood from an art supplies shop and made a frame to mount my LCD panel into my desk -- don't laugh ... it's my first attempt at woodworking. The MDF was 3mm thick so I used a sharp blade to cut out a hole exactly the size of my LCD Panel. Then to cover the "frame" portion of the screen, i glued on some strips of wood. Finally the whole thing was spray painted gray.

To interface it to HDMI, the LCD panel requires a LCD Driver board (which I got on eBay). I decided to fix this to the back of the LCD panel, where it would be mostly out of the way. I attached an extra piece of bassboard and screwed through one of the mounting holes of the LCD board, into the wooden frame. I did a similar thing with the control panel of the LCD Driver board, which I put at the side of the frame.

Fixed everything up, and switched on the power ... and screen came up. Launched my flight simulator and XHSI software (which puts external flight displays on the extra monitors) and proceeded to size and position the Primary Flight Display and Navigation Display windows. Everything worked fine for about ten minutes ... until I decided to reach to the back and adjust the brightness of the LCD Panel. At which point ...

There were two loud firecracker like explosions and the display went black. After a few seconds of panic, instinct kicked in and I switched off the mains power.

What just happened? There was no smoke nor did I smell anything burning. I disconnected the components and reconnected just the power supply -- no more power light. I opened the power supply to find gellish goo and an exploded capacitor inside.
ON further inspection, I also found a burst capacitor on the LCD Driver board:

But what would cause this? After all it worked fine before ... Well, if you've studied the first picture in detail, you'll probably be laughing at me:

Because the wooden frame was quite thin, i used an extra piece of wood to mount the LCD Driver, so that the screw won't pierce to the front of the frame. I wasn't aware of it at the time, but this raised the LCD driver just enough so that the pins from the electronic components at the top end of the board didn't touch anything. But see the metal strip just below it from the frame of the LCD Panel? That's what it escaped from touching ... until I fiddled with the switches. It must have flexed he panel enough that some positive pins on the bottom of the LCD board came into contact with the metal frame, which is connected to ground, causing current to flow the wrong way and big bam boom went the capacitors.

Ideally I would have expected the power supply unit at least to have some over-voltage or short-circuit protection, but it was a cheapish supply that I had ordered with the LCD driver board.

So the LCD Driver and Power supply are obviously a goner. I'll reorder the LCD Driver on its own and try and source a better power supply unit, and probably think of putting it into some sort of casing, or at least a tupperware to prevent any future accidents. Not sure if the LCD panel is ok or not, unfortunately I have no way to test it without a working LCD Driver board.

Oh Well.


I took a really good look at the bottom of the LCD Driver board and the gap is large enough that there is no way it would have made contact with the metal frame at that point. There aren't even any pins directly above the metal frame part. So at this point ... I'm not really sure what caused the capacitors to explode. It's still likely an overvoltage situation, which does point to a short ... but I still don't know the cause. Hmm.
