  • Loose cable connection 
  • Damaged cables 
  • Faulty connection ports

7. JVC TV Won’t Turn Off Or On And Keep Flashing Different Colors

Another problem with your JVC TV that you may encounter is your TV won’t turn on or off, but it keeps flashing different colors.

When TV is stuck in the “Purity Check Mode,” then this happens. In this mode, the full-screen displays colors of green, red, white, blue, and partial white.

To check for the non-active pixels, your TV cycles through these colors. When your JVC TV goes through this problem, this means Service Mode is “ON” on your TV.

After resetting the EPROM, hopefully, this color flashing trouble will be solved. But if it still exists, it means the EPROM is faulty.
