Replacing the display on the HTC Touch Pro (Raphael): Some Tips

Replacing the display on the HTC Touch Pro

How To - Tips

1. Collect information

a. Find the Service Manual HTC Touch Pro (Raphael) on Mike Channons's site, the Raphael wiki or you could Google for it. File name is "HTC Raphael_SM_A10 _GENERIC__01 Dec 08.pdf".

Take a look at the disassembly and assembly chapters of the Service Manual.

The following two lists may be helpful.

List 2: kinds of tape/fabric used in the Raphael

a. Conductive fabric

Self adhesive conductive fabric, parts 14-24 on the SPL. The adhesive backside is also conductive.

b. Mylar

A specific kind of polyethylenetereftalaat (PET) used for electical insulation.

c. Kapton tape

Kapton is a polyimide film which can remain stable in a wide range of temperatures. (electrical insulation)

d. EMI gasket

EMI shields are implemented in a design to isolate one component or section of a device from another.

e. Double sided tape

b. Movies of the disassembly process can be found on YouTube for the HTC Diamond.

The Diamond does not have an integrated keyboard, so it is a bit different, but it is good enough to get an idea of the process.

The information on how to replace the screen itself is not found in the service manual.

c. Study the last few stages of the HTC Touch Pro page on pdacenter.ru

(Translate the page into English using Google.)

The display is attached to the metal frame by 4 small pieces of double sided tape.

3. Get some tools

a. Phillips (cross head) screwdriver size 00x50

The right size is 00. The length, 50mm, is less important.

There is one torque screw in the Raphael (SPL no. 27), but it can easily be handled by a normal screwdriver.

b. Plastic stick (to open the case)

The standard plastic stick I had ordered was actually too big. The one I made myself was smaller and proved to be better.

c. Other tools

I did not use these, but if you plan to do more than one it would be a good idea to use the

- plastic tweezers

- ESD wrist wrap

- rubber gloves

4. Buy a display with touch screen attached to it

You could buy the touch screen and the display separately, but I could not find any information on putting them together. Avoid problems by buying these already attached.

5. Replace the display

a. Disassemble following the Service Manual, leaving the M/B unit in order.

Be careful not to break the small speaker cords. Do not move them too much because they are very fragile.

Be sure to keep every piece of tape safe for reassembly. Buying new tape can be quite expensive.

b. For the last stages, follow the instructions from pdacenter.ru.

Press the old display gently out of the metal frame. Move the pieces of double sided tape from the old to the new display, and fit the new one into the metal frame.

c. Reassemble following the Service Manual.

Good luck! :)
