There are three steps you can take.

1. Slowly adjust the brightness and/or contrast control on the television.
   
2. The TV may need to be "fine-tuned" to channel '3' Locate and adjust the fine-tuning mechanism until the picture comes in clearly.
   
3. If a VCR is connected, it may not be "fine-tuned" to channel 3. Locate and adjust the fine-tuning mechanism until the picture comes in clearly. Also, verify that the <3/4> switch is in the correct position. Locate the switch on the back of the VCR and verify it is on <3>.
