TV’s Universal 
Remote Code

This television follows SONY’s universal remote code. If SunBriteTV is not listed in 
the manufacturer list, look up SONY’s codes in your universal remote’s hand book.

TV channels are 
blocked

Check the Auto Lock function settings on the OSD. Channels may have been locked 
previously.

The TV turns on 
or off slowly, and 
the screen shows 
up slowly

This is a High Definition liquid crystal display panel TV. It requires a few more 
seconds than normal TVs to power up and show the picture.

No sound to PC

Make sure you have a 3.5 mm mini-jack cable connected from your PC’s sound 
output to the TV’s VGA Stereo Input.

HDCP video says 
no HDCP support

Reboot your HDCP video device by turning it off, and unplugging the power cord. 
Wait up to 8 minutes to plug the power back in to see if that works.

HDCP video has 
no audio

Make sure you have a 3.5 mm mini-jack cable connected from your HDCP video 
device sound output to the TV’s VGA stereo input. If your HDCP video device uses 
RCA audio jacks, you’ll need to obtain a RCA audio converted into a 3.5 mm mini-
jack cable.

Cannot get 1920 
x 1080 from PC 
VGA

The screen’s max resolution is 1920 x 1080. Your video card may not support this 
resolution. Check your video card’s maximum resolution, and use that setting.

Picture is 
distorted or has 
an abnormal 
sound

This might be from interference from large electrical appliances, cars, motorcycles 
or fluorescent lights. If the TV is close to the wall, try moving the TV to another 
location to see if the problem still occurs.

Picture does not 
cover the entire 
screen

If you are using HDMI or a TV digital channel, use the Aspect button to switch 
to 16:9 format. If you are using VGA, use the AUTO ADJUST function to adjust to 
the screen. Note: If you are using regular analog TV, AV or component in 480i 
resolution, use the ASPECT button to switch to 16:9 in order to fill up the screen. 
However, this feature will distort the picture.

Trouble

Solutions

Picture quality is 
very poor

For best image quality, view HD wide screen programs. If HD content is not 
available, view “Standard Definition” from a digital source. Standard, analog TV 
will be noticeable inferior to HD quality.

Some pixels are 
always displaying 
the same color

SunBriteTV LCD screens are manufactured with rigorous standards to maintain 
optimal viewing. However, the LCD screen may have minor defects that appear 
as a small bright or dark pixel. This is common to all LCD screens used in display 
and television products, and is not specific to SunBriteTV. For more information,
see SunBriteTV’s Pixel Quality Policy in this manual.

Switching a 
channel or source 
changes the 
volume

Different channels and inputs sometimes have this effect because the channel 
signal’s volume is pre-set. 

There is noise or 
trash pixels on the 
screen

When your TV’s resolution is higher than the digital channel’s broadcast 
resolution, the signal is up-converted to match your TV’s resolution. Up-
converting can cause this kind of effect.

Tips for high-
definition users

The TV is an ideal platform for viewing High-definition content. The best image 
quality can be achieved by HDMI, YPbPr (component), then VGA. However, due 
to variances in broadcast practices, it is possible that some image distortion 
may occur.

Tips for letterbox 
content users

Letterbox (widescreen) versions of DVD movies are most commonly formatted 
for standard 4:3 TVs. The TV has the capability of expanding this content so 
the entire screen is filled, at the expense of the image proportion. To use this 
function, press the aspect button on the remote control and cycle among the 
available options. 

The TV turns off 
automatically

The TV features a power-saving mode which will automatically turn off the TV 
if there is no signal provided for 15 minutes.
