Possible Remedies
❏
If your TV does not turn on and a red light keeps flashing, your TV may need
service. Call your local Sony Service Center.
❏
Make sure the power cord is plugged in.
❏
Press POWER on the front of the TV.
❏
Press TV/VIDEO to cycle through the connected video sources.
❏
Try another channel; it could be station trouble.
❏
Adjust the Picture Mode option in the Video setting (see page 63).
❏
Adjust the Brightness option in the Video setting (see page 63).
❏
Check the antenna/cable connections.
❏
Adjust the Color option in the Video setting (see page 63).
❏
Check the antenna/cable connections.
❏
Try another channel; it could be station trouble.
❏
Press ANT to change the input mode (see page 44).
❏
Adjust the antenna.
❏
Move the TV away from noise sources such as cars, neon signs, or hair dryers.
❏
Using a highly directional outdoor antenna or a cable may solve the problem.
❏
Set Image Shift to an appropriate value. The default setting is Auto. If doubled
images appear with Auto, select the best value from 1 to 4 (see page 79).
❏
You have selected a text option in the Setup setting and no text is available. (See
page 78 to reset Setup selections.) To turn off this feature, set the Caption Vision
option to Off. If you were trying to select closed captioning, select CC1 instead of
Text 1-4.
❏
Some wide-screen programs are filmed in aspect ratios that are greater than 16:9
(this is especially common with theatrical releases). Your TV will show these
programs with black bands at the top and bottom of the screen. For more details,
check the documentation that came with your DVD (or contact your program
provider).
❏
The compression used by certain digital broadcasts and DVDs may cause your
TV's screen to display less detail than usual, or cause artifacts (small blocks or
dots, pixelations) to appear on your screen. This is due to your TV's large screen
and ability to show very fine detail, and is normal for certain digitally recorded
programs. Adjust the reality/clarity in the DRC Palette setting (see page 64) to
optimize the picture while viewing these sources.
❏
The Iris Control may have a problem. Call your local Sony Service Center.
