I've noticed (as have all you Im sure) that the wifi reception isnt the greatest.
I've also noticed (as have all of you) that there is something fishy going on with the responsiveness of the touchscreen.
Want to fix both?
Here is a pic of the internals of the PDP:
As you can see, the Wifi module is on the far left side of the screen, with the wire connecting it to the board taped right across the backside of the touchscreen.
In its current state, if you press on the sides of the PDP's cover, you can see the stress points in the touchscreen (you'll see a ripple effect across the length of where the wire sits behind the screen). This is causing touchscreen inaccuracy issues. And where the wifi antenna is placed, it is causing wifi issues (being that this area is where you are most likely holding the PDP with in portrait mode), as well as the battery causing wifi interference (being that the wifi module is within an inch of the battery).
So here's what I did.
I un-taped the wire from the backside of the screen, and rewired it as shown in the pic below:
I also removed the double stick foam tape from the module and replaced it with some 3M clear double stick tape (it is thinner, allowing for less interference, and also to sit more flush against the unit [as you will be taping the wifi module pretty close to where the USB slot is]). (seen in pic below)!!!.
Some things to note:
- TAKE YOUR TIME and do it RIGHT! You are dealing with thin wires/ribbons here, so any slip up and you could pinch/snap a wire rendering your PDP useless.
- As you open up the case SLOWLY, TAKE NOTE of the way the wires are laid inside the case!!! It is extremely important to note this for re-assembly!!!
- Make sure you feed the wifi wire underneath the ribbon connecting the LCD screen to the circuit board (indicated by the dotted green line in above pic).
- For added security, also feed the wire beneath the small black and red wire located in the top left of the unit (there is a clip that holds the LCD screen in place that I slid the wire under just a touch to hold it in place).
- After the wifi module is secured, make sure the wifi wire that runs in behind the LCD ribbon cable is tucked under the circuit board (if not, you'll have a hard time closing it back up). Seen in pic below.
- Stick a small piece of tape across the braided part of the wire closest to the module itself (this will insulate the wire against shorting out by accidentally touching another exposed piece of the board).
- Secure the wire running along the top side of the PDP with the tape (as shown in pic below, using provided yellow tape). Keep in mind that you will be taping a small 1/4" section of wire to the top most portion of the lcd screen because there is a piece of black plastic case preventing you from being able to string it above the screen (you can notch out a piece of the plastic to fit the wire if you like, but BE CAREFUL).
- Make sure there are no wires being pinched upon closing the device!!!!!!!! (there is a smaller lcd ribbon behind the larger lcd ribbon so BE CAREFUL!!!)
- Upon snapping the device closed, you should NOT have any bulges. A bulge indicates a wire that is being pinched the wrong way, or overlapping the snap point between top and bottom layers of the case -- RE-ADJUST the wires so they lay exactly the way they were when you cracked the case open!!
- Once the case is snapped back shut, insert/tighten the screws, and turn your PDP on to make sure you didnt brick it (lol).
If all is good, you should notice improved wifi reception, and improved touchscreen responsiveness!
I hope this helps.
