Answer 1

There are a number of possible issues that could be causing your Trevio 21-inch TV to malfunction. Here are some of the most common problems and their solutions:

• No power:

  • Check that the TV is plugged in and that the power cord is securely connected to both the TV and the outlet.
  • Try a different outlet to rule out a problem with the outlet itself.
  • If the TV still won't power on, the problem may be with the power supply board. This is a relatively common problem with older TVs, and it can be repaired by a qualified technician.

• No picture:

  • Make sure that the TV is turned on and that the input source is correct.
  • Check the cables connecting the TV to the source devices (such as a DVD player or cable box) to ensure they are securely connected.
  • If the TV still has no picture, the problem may be with the screen itself, the video processing board, or the connection between the two. These problems are more complex to fix and may require professional repair.

• No sound:

  • Check the volume level to make sure it is not turned down too low.
  • Make sure that the speakers are connected to the TV and that the cables are securely connected.
  • If the TV still has no sound, the problem may be with the speakers, the audio processing board, or the connection between the two. These problems are more complex to fix and may require professional repair.

• Fuzzy or distorted picture:

  • Check the picture settings on the TV to make sure they are correct.
  • If the picture is still fuzzy or distorted, the problem may be with the picture tube, the video processing board, or the connection between the two. These problems are more complex to fix and may require professional repair.

• Vertical or horizontal lines:

  • This is a sign of a problem with the picture tube. The tube may need to be replaced, which is a relatively expensive repair.

If you are not comfortable trying to fix the TV yourself, it is best to take it to a qualified technician for diagnosis and repair.
