How to Fix a Sony 32 Trinitron With No Picture


The 32-inch Sony Trinitron TV can deliver programs, movies and video games to your living room or office. The Trinitron series features a variety of connection terminals in the back to support alternate video sources, such as a DVD player, VCR or cable box. Some models feature a toggle between wide-screen and full-screen formats. The Sony V-chip allows parents to rate channels and monitor which programs their kids can watch. After the Trinitron is installed and set up, you might run into setbacks with picture loss.

  • Unplug the Trinitron power cord from the wall or strip outlet to reset the connection if the Trinitron seems to be powerless or if the red indicator light on the front of the TV flashes. Inspect the cord for damage, such as frays or dents. If the cord is damaged, replace it. Plug a separate device into the wall or strip outlet to confirm that the outlet is functional. Unplug the device, if it works, and plug the Trinitron's power cord back into the outlet. If the device failed to turn on, use another outlet.

  • Press the "TV/Video" button on the remote control to confirm that you're in the correct mode. Use "TV" for watching cable television and "Video 1, 2, 3 or 4" to watch video from connected sources, such as a DVD player.

  • Press the "Channel +" or "Channel --" button on the remote control to scroll to another programmed channel, as the currently selected station might be experiencing station problems.

  • Press the "Menu" button on the remote control to access the Trinitron main menu and adjust the brightness of the screen, as it might be completely dark. Use the selector button to highlight the "Video" sub menu and press the "+" key within the selector button to select it. Push the selector button down to highlight "Brightness" and then push the "+" button to select it. Press the selector button to the right to increase the brightness of the picture.

  • Unscrew the 75-ohm coaxial cable from the back of the Trinitron and from the cable source to reset the connection. Inspect the length of the cord for any abrasions or breaks. If the cord is damaged, replace it. Press the cable into the "VHF/UHF" terminal on the back of the TV, and then screw the casing tightly around it. Fasten the other end of the cable in like fashion to the "Cable Out" terminal.

  • Unplug the audio and video cables from the connected device from the back of the Trinitron to reset the connection of a VCR or DVD player, if there is sound but no picture. Match like cable colors to like terminal colors when you plug them back in. Plug the yellow cable into the "Video In 1" yellow video terminal. Plug the red and white audio cables into the red and white "Video In 1" terminals.
