While I had been busy developing the Glad Happy Feet flash game, the parts of the Samtiq have been slowly arriving. The 14V power supply for the monitor arrived yesterday and I tested the monitor, it’s working fine so I started the task of stripping the monitor. Here is the monitor before stripping starts:
This monitor is a bit tricky to open up, I had to look for hidden screws and then pry open the plastic cover by sliding a flat-head screw driver around the case to pry it open. Here is the monitor with the face removed:
This monitor has an external power supply and a base which has the connectors for 14V DC input, VGA and DVI. These inputs are carried through the base and the stand and fed to the main monitor case. Again it was a matter finding the screws to undo and prying open some plastic face coverings. All the above signals are fed to the monitor through one single connector which I had to carefully pry out. Once that was done the plastic back of the monitor was released.
There is some shielding which is easily removed via a couple of screws, once the shielding is off we are left with just the LCD, controller and inverter boards:
All the connectors on this monitor had a big dab of glue on them, once the glue was scrapped off the connectors could be removed and couple of screws undone to separate the LCD from the controller and inverter boards:
This is a close up of the controller and inverter boards:
After removing the above circuit boards, things started getting a bit dicey. The LCD has a metal backing which I guess acts as the shielding but the wacom tablet cannot sense the pen through this shield so it had to go. The problem is that this metal shielding also hold things in place so I need to find some way of holding things together if I want to have a usable unit.
It took a while to strip the LCD, there are lots of metal tape and I had be careful with the LCD row/column circuit boards. I removed the backlight lamps by undoing the tiny screws on ones side and then sliding them out. That frees up some other parts but the plastic casing hang onto other parts with little tabs which need to be carefully pried open. I don’t like this prying open of plastic parts, it’s much nicer when there are screws that can be undone and the thing comes apart. Anyway this stage of the strip was pretty scary too easy to damage things. I was concentrating hard so I didnt take too many photos but here is what the LCD sheet looks like with the backlight module removed:
As you can see in the image, there is a FFC (Flat Flexible Cable) connecting the Column driver circuit board to the Row driver circuit board. I counted the tiny connections a couple of times (and I mean TINY!) there are 20 of them and the pitch (which is the distance from one gap to the next) is 0.5mm. This is standard FFC but unfortunately the only place in Australia selling the components for making up an extension is RS and they have a minimum order of 5 or 10. So I am looking at getting this part from Lumenlab or DIY-Beamer.
So that’s where I am with the Samtiq, I will post more info as I get the parts.
