Why 75 Inch TV Repairs Are Different
A 75-inch TV is a large-format display — most commonly LED, QLED, or OLED — and its sheer size means:
- More backlight zones that can fail independently
- Larger, more expensive panels that are harder to source
- Heavier boards and assemblies requiring careful handling
- Higher voltage power supplies that need specialist technicians
At Refitec, we have hands-on experience repairing large-format TVs across all major brands including Samsung, LG, Sony, Hisense, TCL, and Skyworth. If you’ve been Googling “TV service center near me” in Nairobi, you’ve found the right place.
Common 75 Inch TV Problems — Detailed Diagnosis & Repair Guide
1. 🔲 Black Screen / No Picture (Backlight Failure)
Quick answer: Your TV’s backlight strips have failed. You can usually still hear sound. This is one of the most common 75-inch TV faults.
How to Confirm It:
- Shine a torch at the screen — if you can faintly see an image, the backlight is dead
- The TV powers on (standby light is on) but the screen stays dark
- Sound plays normally
What Causes It:
- LED backlight strips burning out over time
- A faulty LED driver board
- A failed inverter board (on older models)
How Refitec Fixes It:
- We open the TV safely in our workshop
- We test each backlight strip with a diagnostic tool
- We replace the faulty LED strips or driver board
- We reassemble and calibrate brightness settings
- We do a full burn-in test before return

2. 🟫 Half Screen Dark, Vertical Lines, or Horizontal Bars
Quick answer: This is almost always a T-Con (Timing Controller) board issue. The T-Con controls how image data is sent to the panel.
How to Confirm It:
- One half of the screen is brighter than the other
- Vertical or horizontal colored lines appear
- The image looks garbled or split
What Causes It:
- T-Con board component failure
- Damaged ribbon cables (flat flex cables) between T-Con and panel
- Voltage fluctuations that burn out T-Con components
How Refitec Fixes It:
- We remove and inspect the T-Con board under magnification
- We test all ribbon cable connections for continuity
- We replace the T-Con board or resolder failed components
- We confirm full-screen output before handover
Repair Cost at Refitec: KES 4,000 – 9,000 📞 Call or WhatsApp: 0704843613
3. ⚡ TV Won’t Turn On (Power Supply Board Fault)
Quick answer: No standby light at all? The power supply board has failed. This is one of the most repairable faults on a 75-inch TV.
How to Confirm It:
- No standby light (red or white indicator)
- TV is completely dead — no sound, no screen
- Power cable and wall socket are confirmed working
What Causes It:
- Blown capacitors on the power supply board
- Surge damage from unstable Kenya Power supply
- Failed rectifier or fuse
How Refitec Fixes It:
- We safely discharge the power board capacitors
- We test all components with a multimeter
- We replace blown capacitors, fuses, or the full board if needed
- We apply surge-protection best practices and advise on use of a UPS

4. 🖥️ Cracked or Physically Damaged Screen
Quick answer: Unfortunately, cracked screens on 75-inch TVs are expensive to repair due to the cost of large panels. In some cases, a replacement is more economical.
How to Confirm It:
- Visible cracks, spider web patterns, or ink bleed on the display
- Screen is physically shattered after a fall or impact
- Dead pixels spreading from a central impact point
What Causes It:
- Physical impact (objects, children, transport accidents)
- Pressure cracks from mounting or moving the TV incorrectly
How Refitec Fixes It:
- We assess the damage and check panel availability
- We provide a transparent quote before any work begins
- If panel replacement is viable, we source and install a compatible panel
- We advise honestly if buying a replacement TV is more cost-effective
Repair Cost at Refitec: KES 25,000 – 60,000+ (panel-dependent)
⚠️ Note: We will never charge you for a diagnosis. We give honest advice — if repair isn’t worth it, we’ll tell you.

5. 🔄 TV Keeps Restarting / Rebooting in a Loop
Quick answer: This is typically caused by a firmware corruption, overheating, or an unstable power supply board.
How to Confirm It:
- TV turns on, shows logo, then restarts repeatedly
- TV shuts off after a few minutes of use
- Remote commands are ignored mid-session
What Causes It:
- Corrupted system firmware (common after power outages)
- Failing capacitors on the main or power board
- Overheating from blocked vents or faulty cooling
How Refitec Fixes It:
- We attempt a firmware recovery or factory reset via service mode
- We inspect and test the power supply and main board
- We clean internal dust build-up and check thermal performance
- We flash updated firmware if required
Repair Cost at Refitec: KES 2,000 – 5,000 📞 Call or WhatsApp: 0704843613
6. 🔊 No Sound or Distorted Audio
Quick answer: Sound issues on large TVs usually come from blown speakers or a faulty audio processing section on the main board.
How to Confirm It:
- Picture is fine but no sound
- Sound is crackling, buzzing, or only works on one side
- External speakers work fine via HDMI ARC or optical, but built-in speakers don’t
What Causes It:
- Blown internal speakers (common on high-volume use)
- Damaged audio amplifier IC on the main board
- Loose or corroded internal speaker connectors
How Refitec Fixes It:
- We test speakers directly with a signal generator
