Reason 1: Backlight Failure — The Most Common Cause
Quick Answer
If your Vision Plus TV has sound and you can faintly see an image when you shine a torch at the screen, your backlight LED strips have failed. This is the single most common cause of a black screen with sound.
Detailed Explanation & Steps
Modern Vision Plus TVs use LED backlights to illuminate the LCD panel. When one or more LED strips burn out, the screen goes completely dark even though the TV is functioning normally in every other way.
How to confirm it’s a backlight problem:
- Turn on your Vision Plus TV in a dark room.
- Shine a bright flashlight or phone torch at an angle directly on the screen.
- If you can see a faint image or menu — backlight failure is confirmed.
What Refitec does:
- Full diagnostic to identify which LED strip(s) have failed
- Replacement of faulty LED backlight strips with quality-matched components
- Full reassembly and picture quality testing before return
⚠️ Do not attempt to open the TV yourself. Vision Plus flat screen panels are fragile and can crack under pressure. Let a certified technician handle it.

Reason 2: T-CON Board Fault
Quick Answer
The T-CON (Timing Control) board converts signals from the main board into the image displayed on screen. A faulty T-CON board causes a black or distorted screen even when audio works perfectly.
Detailed Explanation & Steps
The T-CON board is a small circuit board inside your Vision Plus TV that controls the LCD panel timing. When it fails, you may experience:
- Completely black screen with normal sound
- Half the screen dark, half with picture
- Distorted lines, washed-out colours, or scrambled image
Common causes of T-CON failure:
- Power surges or unstable voltage
- Overheating over time
- Manufacturing defects
- Age-related component wear
What Refitec does:
- Tests T-CON board voltage outputs
- Repairs or replaces faulty T-CON board
- Tests full picture quality across all inputs (HDMI, AV, digital)
💡 A T-CON board repair is significantly cheaper than buying a new TV. Contact Refitec for a free quote.

Reason 3: Loose or Damaged Internal Ribbon Cables
Quick Answer
Your Vision Plus TV has several ribbon (LVDS) cables connecting the main board to the screen panel. If these are loose, torn, or disconnected, you’ll get sound with no picture.
Detailed Explanation & Steps
Inside every Vision Plus TV, flat ribbon cables carry picture data from the main board to the T-CON board and then to the display panel. These cables can:
- Come loose due to vibration or movement of the TV
- Get damaged during previous amateur repairs
- Develop micro-tears from heat expansion over years of use
Signs this is your problem:
- Picture was intermittent before going fully black
- TV was recently moved, dropped, or previously opened
- Screen flickers momentarily before going black at startup
What Refitec does:
- Safely opens the TV casing
- Inspects all ribbon/LVDS cable connections
- Reseats or replaces damaged cables
- Closes and tests before handover
🔧 This is a delicate job — ribbon cables tear easily if mishandled. Always use a trained Vision Plus TV repair technician.

Reason 4: Main Board Failure
Quick Answer
The main board is the brain of your Vision Plus TV. When it fails partially, it can process audio but fail to produce or send a video signal, resulting in sound but no picture.
Detailed Explanation & Steps
The main board (also called the motherboard or logic board) handles tuning, HDMI input processing, USB playback, and picture output. A partial failure means audio circuits still work while video processing breaks down.
Signs your main board may be at fault:
- No picture on ANY input (HDMI 1, HDMI 2, AV, TV aerial) — all show black
- TV turns on, backlight comes on, but screen stays blank
- Backlight test (torch test) shows NO image at all — ruling out backlight failure
Common causes:
- Lightning strike or power surge
- Short circuit from liquid spill
- Aging components after years of use
- Firmware corruption in some cases
What Refitec does:
- Isolates main board fault through systematic component testing
- Repairs faulty sections (voltage regulators, HDMI ICs, video processors)
- Replaces board entirely when repair is not cost-effective
- Installs and configures replacement boards with correct firmware
📌 Main board repairs require experience with Vision Plus TV models specifically. Generic technicians often misdiagnose this — trust a certified Vision Plus TV repair center.

Reason 5: Faulty Capacitors on the Power Board
Quick Answer
Blown or bulging capacitors on the power supply board cause insufficient or unstable voltage, which often kills the picture while audio — which uses less power — continues working.
Detailed Explanation & Steps
Capacitors are small cylindrical components on the power board that store and regulate voltage. Over time — especially in environments with frequent power fluctuations (very common in Kenya) — they bulge, leak, or fail entirely.
How to suspect capacitor failure:
- TV takes longer and longer to show a picture before going black entirely
- Picture cuts out intermittently, especially when the TV is warm
- You hear a faint hissing or buzzing sound from inside the TV
- TV has experienced power surges or has been used with an unstable power supply
What Refitec does:
- Opens power board for full visual and electrical inspection
- Identifies blown, bulging, or low-capacitance capacitors
- Replaces with quality-rated capacitors matched to your Vision Plus TV model
- Tests board under load before reassembly
⚡ Pro tip: Always use a surge-protected power strip or stabiliser with your Vision Plus TV in Nairobi to extend the life of your power board components.
