Possible Remedies
❏
If your TV does not turn on and the POWER LED keeps blinking in red, 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 Picture setting (see page 34).
❏
Adjust the Brightness option in the Picture setting (see page 34).
❏
Check the antenna/cable connections.
❏
Adjust the Color option in the Picture setting (see page 34).
❏
If you set the Power Saving option to On, it will enhance the black level.
Check if the Sleep option is activated, or confirm the Duration setting of Timer
(page 46).
❏
If the temperature is too high, the TV may also turn off after a warning message is
displayed.
❏
Check the antenna/cable connections.
❏
Try another channel; it could be station trouble.
❏
Press ANT to change the input mode (see page 22).
❏
Move the TV away from noise sources such as cars, neon signs, or hair dryers.
❏
If using 300 ohm twin lead, move the excess lead away from the TV or try using
75 ohm coaxial cable instead.
❏
Using a highly directional outdoor antenna or a cable may solve the problem.
❏
You have selected a text option in the Caption Vision (CC) feature in the Setup
setting and no text is available (see pages 45 and 48). To turn off this feature, set
the Caption Vision (CC) option to Off. If you were trying to select closed
captioning, select CC1 instead of Text 1-4.
❏
The current Wide Mode setting is automatically replaced with the 4:3 Default
setting when you change the channel or video input, if 4:3 Default in the Screen
settings is set to other than Off. If you want to lock in the Wide Mode selected
with the WIDE button, set 4:3 Default to Off in the Screen settings (see page 40).
❏
Check the Auto Wide option in the Screen settings (see page 39).
❏
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 35) to
optimize the picture while viewing these sources.
