First, you will want to check your connection. You can do that by following the instructions here. To check power connections:
- Look for loose power cords. Make sure they are plugged in all the way.
- If the wall outlet is controlled by a wall switch, make sure the wall switch is in the ON position.
To check video connections:
- Tighten loose coax cable, (threaded).
- Tighten loose video cable (yellow).
- Tighten loose HDTV cables (set of red, blue and green connectors).
- Follow the cables to ensure they have not been damaged in any way.
Important: Make sure the color of the cable connectors match the color of the plug-in ports, especially the yellow connector or the set of HDTV red, blue, and green connectors. If there were no loose connections, then you will want to check for a setting that was changed.
If a VCR is connected, then:
- With the TV ON, turn the VCR OFF (and DVD player OFF, if installed). If the TV picture did not return, go to the next step.
- Turn ON the TV and VCR. Put the TV and VCR on the same channel, usually channel 3 or 4 (also try channel 2). Older VCRs have a small switch on the back panel that switches from channel 3 to channel 4.
If the TV was recently used to play video games, VCR tapes, DVD movies or home camera movies, then you may need to return the INPUT to the TV:
- Press the INPUT button (may be labeled TV/Video, Source or Antenna) on the TV or the remote control that came with the TV.
- A menu will display on the TV screen. Select the option for TV. It may be labeled Cable TV, CATV, CAB, Input 1, Video 1, Antenna 1, AV1, HDMI, DVI or another name (check the TV user manual). Usually, the label describes the type of connection from the cable box to the TV (such as cable, AV, HDMI, DVI or Component).
- Or select each option, one at a time, returning to live TV to see if the option restored the picture.
