This is normal. “PC” is always shown in the source list, regardless of whether a PC is
connected.

Picture
First, perform the
Picture Test
and to see if your product is properly displaying the test
image (go to
Menu
→
Support
→
Self Diagnosis
→
Picture Test
).
If the test image is properly displayed, the poor picture may be caused by the source
or signal.
The product image does not
look as good as it did in the
store.
Store displays are all tuned to digital, HD (high definition) channels.
If you have an analog cable/set top box, upgrade to a digital set top box. Use HDMI or
Component cables to deliver HD (high definition) picture quality.
✎
Many HD channels are up scaled from SD (Standard Definition) contents. Look
for a channel that is broadcasting true HD content.
Cable/Satellite subscribers: Try HD channels from the channel line up.
Air/Cable Antenna connection: Try HD channels after performing an Auto
Program.
Adjust the Cable/Sat box video output resolution to 1080i or 720p.
The picture is distorted: macro
block error, small block, dots,
pixelization
The compression of video contents may cause picture distortion especially in fast
moving pictures such as sports and action movies.
A weak or bad quality signal can cause picture distortion. This is not a product issue.
Mobile phones used close to the product (within 3.3 ft) may cause noise in the picture
on analog and digital channels.
Color is wrong or missing.
If you’re using a Component connection, make sure the component cables are
connected to the correct jacks. Incorrect or loose connections may cause color
problems or a blank screen.
The color is poor or the
picture is not bright enough.
Adjust the
Picture
options in the product menu (go to

Adjust the
