Signal Problem
To test if the color problem is localized to a specific signal, follow
these steps;
- If you are using an external set-top-box or Coax (RF) connection to
recieve TV go to Step 1.
- If you are using a different external device (for example:
DVD player, Blu-Ray player, game system, etc.) skip to Step 3.
- Switch to a different channel.
- If the problem does not occur on other channels please contact your
service provider. This is not a television issue but appears to be a
signal problem.
- If the problem occurs on other stations continue to Step 2.
- Test both HD and SD stations.
- If the problem occurs on only the HD station but not SD stations
or vice versa please contact your service provider. This is not a television
issue appears to be a signal problem.
- If the problem occurs on both HD and SD stations continue to Step
3.
- Test a different source
For example: A DVD player, Blu-Ray player, game system,
etc.
- If
the problem does not occur on the second source this problem may be
caused by a TV setting on the orignal source and requires
further troubleshooting.
- If
the problem occurs on the second source as well this could be caused
by a picture setting in your TV or a malfunction.
TV Setting
There are many settings in the TV that can change
the
color. Follow the steps below to determine if the picture color is caused by
a TV picture setting;
- Change
the picture mode to "Standard".
- If
the picture problem is resolved then the color problem was caused by
a setting in the original picture mode.
- If
you are already set to "Standard" or the problem was not resolved
continue to Step 2.
- Reset
the picture mode to factory default.
- If
the picture problem was resolved the color problem was caused by a setting
in the picture mode.
- If
the problem was not resolved continue troubleshooting.
Defective Cabling
Improperly
connected or defective cables can cause you to have improper color on the TV.
Follow these steps to determin if your cabling is defective;
- Confirm
that all cables are connected to the correct inputs and all connections
a secure and fully inserted.
Tip:
The component and composite A/V connection are a shared input. Make sure
that the cables are connected properly.

- If
the problem is resolved your cables were connected improperly or had
become disconnected.
- If
the problem is not resolved continue to Step 2.
- Replace
the current cables with new cables or known working cables.
- If
the problem is resolved the original cables are defective.
- If
the problem is not resolved, review "Defective TV Input Or
External Device Output".
Defective TV Input Or External
Device Output
At
this point we have determined that the problem is either being caused by a defective
input on the TV or a defective output on the external device.
To test this test
a different device in the same input on the TV.
For
example: If you have the color problem with your cable STB and it is connected
to HDMI 1 disconnect the cable STB from HDMI 1 and connect a Blu-ray player
to HDMI 1.
- If
the color problem does not happen with the second device then the original
device has a defective output and needs to be serviced.
- If
the color problem continues with the secondary device then the TV needs
service to repair the defective input.
External Device Setting
Many external devices have their own video processers and scalers.
You may
be able to change or adjust the picture in the settings of your external device.
Unfortunately because of the large number of different products on the market
we will not be able to give instructions for all devices.
We have provided a
list of common settings that if changed can cause color problems on your TV.
Please contact the manufacturer of your external device for further assistance
with this step.
- Color Space: Color space refers to the color gamut that the external
device is outputting. There may be an option for RGB, xvYCC, Auto, etc.
Try setting this option to RGB for testing purposes.
- HDMI Color: This is just like color space and will usually have
the option for expanded, wide, and normal. Try setting this option to normal
for testing.
- White Balance: White balance will change the color white to be
either more blue or red. This will affect all other colors on the screen.
Your
external device may not have these settings or these setting may not be affecting
the picture.
If these settings do not correct the picture color or your external
device does not have these settings review "Defective
Cabling".
