View the BRAVIA Image available on your TV to confirm picture quality. BRAVIA image
is sample image available by default on your BRAVIA.
For R Series
Press the HOME button, and then go to Media > Photo to view sample image.
If BRAVIA image is clear →no issue with
your TV, most likely this is because of the
content quality. Refer to page 5 for more
details.
If BRAVIA image is not clear → service may
be required. Please consult to Sony Contact
Centre.
For W Series TV
Now you can run Problem Diagnosis to troubleshoot Picture/Sound symptoms.
Press the HOME button, and then select Help → Customer Support → Problem

Standard Definition (SD) and High Definition (HD)
Standard Definition (SD) has a vertical resolution between 480 and 576 lines.
High Definition (SD) has a vertical resolution between 720 and 1080 lines (Full HD).
When SD video signal is displayed on HD TV, the image will either appear smaller on
or up-scaled (resized) to fit the screen.
Some DTH or set-top box (depends on the providers) may upscale SD signal to HD
levels. However, this can erode the quality of the pictures or even crop the image. For
example, 4:3 image can be up-scaled and then cropped to display full screen image on
16:9.
Tips:
HD TV channels require you to have a
special set-top box that receives HD signals
and routes the content to the TV via an
HDMI cable.
