Picture Distortion or "Weak or No Signal" Message On Component Or AV Connection

If you are experiencing a "Weak or No Signal" message or picture distortion when using the component or AV cable connection.

Please confirm that the adapter is fully inserted into its input.

If you are still experiencing a problem your external source may be the source of the problem.

Test a different device with the component/AV connection.

If the second device does not have the same issue then your original device is the source of the problem. Please contact the manufacturer of the original device for further assistance.
