HP iPAQ hx4700 series Pocket PC

Disassembly, Screen Removal & Re air

Guide

I have used my

Hewlett-Packard

Pocket PC for

about a year and a

half without any

problems, until I

was faced with a

very sad surprise

one day. The

screen was dead. I

still have no idea

how that might

happen: my iPAQ

has a screen

protector, and,

moreover, I always

carried it in a small

case.

As I was not sure

whether my iPAQ

was still under

warranty or not

and I had no idea

how long it may

take to repair a

pocket PC in

Adelaide or how

much it may cost, I

decided to repair it

myself. I bought a new iPAQ hx47 LCD screen from eBay (it

cost 7 AUD, and there were a T6 screwdriver and a case opener

tool in the kit). Unfortunately, I couldn't find any good

instructions for disassembling an HP iPAQ 47 (or any other HP

PDA 47xx series) on the Internet, so it took a bit more time to

me to discover how to replace the broken LCD screen. I have

made the following instruction in case it would help someone

else. However, please note that I'm not responsible for any

damage caused to yourself or your unit by using the following

instructions.

You need a crosshead screwdriver, torx T6 screwdriver, and a

case opener tool (or something like that).

Unplug all devices, remove all SD/MMC cards.

Take the battery off, and remove the 4 screws on the back of the

unit using the T6 screwdriver.

Take the plastic corner off.

With all 4 screws removed you can take off the back cover. It is

clipped on, so it might be hard to remove. In this case use the

case opener tool: slide the tool all the way around the case and

releasing the plastic tabs.

Detach the two ribbon cables. To do this, release the tabs on

each connector. The smaller ribbon connector has a tab, which

should be picked and pulled upward. The larger connector has a

tab (dark brown in the photo) which shoud be picked on its

ribbon side and opened for up to a 45 degree angle (like a small

door). Once the tab is lifted up, you can now slide the ribbon

cable out. Be very careful, the connectors are extremely

fragile and can be easily damaged! Then remove a small

crosshead screw in the other angle of the unit.

Remove the transmitting module. Take the bottom edge of the

module and gently pull upward to disconnect the black connector

(pointed by arrow on the image). Then disconnect the wire

connector and remove the a crosshead screw nearby (outlined by

circle). After that, the motherboard can be easily removed.

After motherboard removed, unscrew 2 crosshead screws as

image below shows.

To remove the LCD screen, you should carefully release two tabs

on its side that has no ribbon cables. To release these tabs, you

need to remove two small items of rubber between the tabs and

PC case, then release the tabs and the LCD screen should come

out (slide the screen a little aside before bring it out).
