Touch Screen Fails To Sense Stylus
I had the same problem and tried several of the solutions here, from
cleaning around the edges of the screen, to soft and hard resets. They
worked for a time, but eventually, the pointer didn't register at all.
Before you throw out your unit, look on Ebay for the replacement
digitizer. There are or were many when I looked, ranging from about $8
to considerably more. None of the low cost ones came with instructions,
but did come with tools. Higher priced offerings were for having them
replace the digitizer for you. I ordered the low priced one and figured I
could figure it out. The tools they send are two tiny screw drivers
with special tips and a small plastic device to pry the sections apart.
If you want to do it yourself, I will be happy to explain what I did.
Remember to be really gentle when you do every step. First use the pry
tool on the place where the cord plugs in to connect the device to the
usb slot on your computer. It is tight, but gently pry out the small
black rectangle. You will see two tiny screws inside. Remove those,
carefully with one of the screwdrivers that come with the digitizer and
set them someplace save. These two screws or bolts have nuts, that you
can't really see until the next step. Watch for them if they fall out.
The next step is to use the pry tool around the edges of the white
plastic face of the Z22 and separate it from the back. I would lay it on
the back while you do this. There is a small u-shaped piece that is
part of the reset button and it fits on a peg on the back part of the
device. Carefully ease the front and back apart. There are 4 small
screws that still need to be removed. Save them to replace when done.
Remove the innards of the device, but Don't totally separate the
sections. There are foil connectors that attach the parts and they need
to be intact. Gently ease the digitizer from the white plastic face. It
will have another white plastic box on it's back side. Use the pry
device to separate the glass digitizer from that white box. You will see
there is a gold striped foil connector on your new digitizer, about
midway up the side of the device. Find the one that is connected to the
old digitizer and ease it out of the slot. Remove the old digitizer.
Slide the new connector into the slot. Position the new glass digitizer
correctly over the white plastic box and place the innards face down
into the white face of the Z22. Replace the 4 screws. Gently close the
case, laying the front onto the back, so you don't displace the reset
button part. Snap together and replace the two tiny screws into the
section near the power cord connector. (Hopefully you didn't drop the
little nuts out, during the process. If you did, you may have to back
track until you can see the small white boxes that they slip into, in
that location. Email me if you have problems with this. It sounds a lot
worse than it was. When I finished, I was really disappointed, because
it didn't turn on, the whole screen was black, which was worse than when
I started. But, after I plugged it in, and let it charge about 3 hours,
it worked perfectly! I am so excited! You can do this if you are
patient and gentle.
If you partially opened the case, you may have had the restart button piece shift out of place. You need the tools that come with the new digitizer, or a very delicate tool to pry out the rectangle,around the power cord connection, and remove two tiny screws, before you can separate the front and back. The tool they send to do that is sort of soft plastic, tiny spatula shaped piece which can squeeze into the grooves and gently separate that piece and the front from the back.
