I don't see any picture but I can hear
the sound
If your Xperia Touch suddenly stops projecting an image or video even though you
still hear audio, the device may be too hot. That is because Xperia Touch is
designed to stop emitting light when it reaches a certain temperature.
Try these methods one after the other. Verify whether the problem was solved
after each method, before trying the next one.
•
Check if the cooling fan is working by listening for the sound generated by the fan.
If the fan isn't working, contact your retailer or a Sony Mobile repair partner.
Before handing the device over for service, back up all your data to avoid possible data loss.
Data on the device may get deleted when examined. Don't forget to bring proper
documentation, for example, proof of purchase and warranty card. The documentation
required may vary depending on market, country, or region.
•
Overheating may be a result of accumulation of dust and other particles in the
mesh outer cover of Xperia Touch. Use a vacuum cleaner with a soft brush tip to
clean the cover from the outside.
The projected screen is blurred or
difficult to read
The quality of the projected screen depends on the usage environment, such as
lighting conditions and the properties of the projection surface.
•
Do not place the device or project the screen in direct sunlight or strong
fluorescent light. This may have a negative impact on the projected image as well
as on the touchscreen functionality.
•
Do not project the image onto a glossy surface such as a glass or metal table top
or wall.
•
Make sure the projection window is clean, and that you have removed the
protective film designed to protect the projection window during shipping.
•
If you are projecting onto a wall, make sure there is no obstacle between the laser
auto focus sensor and the projection surface. The laser auto focus sensor is located
on the bottom panel of the device.
•
If you move the device during projection, make sure projection temporarily stops
to let the device refocus after being moved. To stop projection, lift the device a
little bit when you move it. You can also press the power key briefly to deactivate
the screen before moving the device and to activate the screen again when you're
done.
