outlet.

Picture quality is not as good as viewed at the store

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

Diagnosis → Picture/Sound Symptoms.

After starting the diagnosis, follow instructions on

the screen to diagnose the symptom and possible

cause.

Display/Picture

4 | P a g e

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.
