A snowy background with the message “Weak or No Signal” will show on customer’s display. A snowy screen generally indicates that the TV is set to TV INPUT mode. Please proceed with the following troubleshooting questions in this specific order:

 

1-      Does cx have a SAT receiver or a Cable box connected to the TV?

2-      If the answer is “YES”, please ask cx what type of connection is being used between both devices: HDMI, COMPONENT or COMPOSITE? (details further down in NOTE on why this question);      NOTE: if customer does not know go to STEP 3. If customer indicates that he is using an HDMI or COMPONENT or COMPOSITE connection, please proceed to STEP 4.

     3-      Ask cx to take the SAMSUNG TV’s remote and push the INFO button: a screen similar to the following will show:

1-      If INFO button shows CABLE (X) –i.e.: Cable 3- advise cx to use the SOURCE button on the SAMSUNG TV’s remote and go slowly through each INPUT source.

2-      One of them will show the actual feed from SAT Box or Cable Box (i.e. HDMI 1, HDMI 2, COMPONENT…) and get the picture back on (issue resolved).

THIS IS NOT A SERVICE RELATED ISSUE: CX ACCIDENTLY JUST CHANGED THE TV SOURCE AND LOST THE FEED.

NOTE: There might be cases where, cx having a Cable Box (STB or Set Top Box) or a SATELLITE receiver, he/she has his/her devices connected to TV using and HDMI cable.

 Cx will complaint about being on the actual HDMI input used for Cable Box or SAT receiver and either:

a-      Has audio but no video feed;

b-      Has video but no audio feed;

c-      Has no audio or video feed.

This is a known issue, which occurs when connecting a Cable or Sat Box to TVs using an HDMI connection. It is recommended as alternative, to USE A COMPONENT CONNECTION INSTEAD. Cable and Satellite Box MANUFACTURERS are to update their box to the latest HDMI firmware (v. 1.4).s
