TV Main Board (Motherboard) Spare Part Repair & Replacement

By Prologic Technologies

Understanding the TV Main Board (Motherboard)

The TV main board, also known as the motherboard, is the central component that controls all the functions of your television. It processes signals from inputs (HDMI, USB, antenna) and manages the display, sound, and smart features. When this critical part malfunctions, your TV may experience issues like no power, no picture, distorted audio, or failure to respond to remote commands.

At Prologic Technologies, we specialize in TV main board repair and replacement, ensuring your television operates smoothly with high-quality spare parts and expert technical service.

Common Signs of a Faulty TV Main Board

If your TV is acting up, the main board could be the culprit. Look out for these symptoms:

  1. No Power or Random Shutdowns – The TV won’t turn on or keeps turning off unexpectedly.
  2. No Picture (Backlight Works) – The screen stays black, but the backlight is on.
  3. No Sound or Distorted Audio – The TV displays an image but produces no or garbled sound.
  4. Frozen or Unresponsive TV – The system freezes, or the remote/buttons don’t work.
  5. HDMI/USB Ports Not Functioning – Connected devices aren’t detected.
  6. Lines or Artifacts on Screen – Strange patterns appear due to signal processing errors.

TV Main Board Repair vs. Replacement

When your TV’s motherboard fails, you have two options: repairing the existing board or replacing it entirely.

When Repair is Possible

  • Minor capacitor or resistor failures
  • Loose connections or solder issues
  • Corrosion due to moisture exposure

Our technicians at Prologic Technologies use advanced diagnostic tools to identify and fix repairable faults, saving you money compared to a full replacement.

When Replacement is Necessary

  • Severe physical damage (burnt circuits, water damage)
  • Unavailable or obsolete components
  • Multiple component failures making repair impractical

We source high-quality, compatible main boards for all major TV brands, including Samsung, LG, Sony, Hisense, and more.
