Screen Replacement for MDA Compact III / HTC Artemis

Once again I'm providing service information for a product because I broke my own, hadn't insured it, so had to fix it myself *sigh*.

T-Mobile's MDA Compact III is actually an HTC P3300 (aka Artemis) sans wi-fi. Like many of these PDAs, the screens are big, and therefore fairly vulnerable. I found this out earlier today; I had the phone in the front pocket of my jeans, and glanced a doorway with my leg as I walked past. Next time I looked, the LCD had cracked and was completely black. Great. The moral is a) insure your expensive phone and b) if you're going to keep it in your pocket, have the screen facing your leg, not outwards (or how about using a protective case, genius?).

Replacement screens for many smartphones and PDAs can be found on eBay for around £40 including p&p and a tiny 5mm torx driver - bargain!

Disclaimer: If you choose to follow these instructions, you do so at your own risk, and I cannot be held responsible for any damage you may cause through your own negligence. You could also invalidate any warranty your phone may have.

Remove the stylus, the battery panel and the battery:

There's a plastic panel on the top half of the phone (on the left in the above picture), which incorporates the protector for the digital camera. If you've got decent fingernails, you can pull the panel away from the main chassis. You can use a screwdriver blade to push under the panel and lever it up, but be careful with regards to scratches. Be confident with it - it unclips and lifts straight out if you do it in the right direction (straight up):

The panel is also attached at the top of the chassis. Once it's loose at the top of the battery bay, push that edge towards the top of the phone and it should pop out fairly easily.

You can now see a screw in each corner of the MDA - I think these are 5mm Torx screws (my 6mm bit worked okay as it's a bit worn), and one of them is covered by a warranty label (you can just pierce this with the screwdriver rather than try and peel it off):

Now the bottom corners of the phone are free from the front case, and you can prize the two apart - clips along each side of the phone will be released:

Once the sides are free, the top of the phone is still clipped together. Insert a small, flat head screwdriver into two positions at 1/4 and 3/4 along the top of the MDA, and twist the blade. This will unclip the back case:

There are 3 black crosshead screws holding the main circuit board in place. Remove these, and unclip the orange ribbon cable:

Remove the ribbon cable from its connector and this will release that side of the circuit board, while the other side is secured by a similar connector. Disconnect this as well, and remove the circuit board. Look out for the rubber grommet that sits on top of the microphone (next to the USB port, on the other side of the board), as it comes off easily.
Our focus is now on the front case, incorporating the LCD:

The next part is a little tricky. the metal shield is held onto the front case with clips, halfway down the length of the MDA. Push the head of a flat screwdriver into each of the indicated holes (not simultaneously), while pulling the bottom of the shield up. It should unclip. Don't force it if it doesn't come easily:

Continue to lift the shield so it rotates upwards - once it's vertical, the top of the shield will lift out of the chassis.
You've now removed the front case. The screen is secured to the shield with sticky pads. Again, you can lift the bottom of the LCD, firmly but gradually, rotating it upwards so that it comes away from the pads:

This leaves you with the (broken) LCD module ready to be replaced, including the touch-sensitive membrane, which is stuck to the front. woo-hoo.

I'd just like to say thanks for fairly comprehensive guide to removing the LCD from my MDA. Your guide was so useful that I was able to replace the cracked touch screen myself. Cheers David
