Common Symptoms Our Service Covers:

  • Stuck on Sharp Logo
  • TV shows logo but then shuts off
  • TV Cycles on and off
  • Audio Failure
  • Menus are slow to respond
  • Sometimes the TV freezes
  • Standby light flashes continously
  • If the standby light blinks every few seconds, it's a 1-blink error due to faulty LED strips. Replace them, and then send in your mainboard for reprogramming, which our service covers. Reinstalling the mainboard without replacing the LED strips will lead to a recurrence of the issue.

    New LED strips for sale (80" model only)

Symptoms we DO NOT fix:

  • TV is completely Dead (no power)
  • HDMI failure
