Read moreIs your television acting up? You are not alone. At Nairobi Repair Center, our technicians handle TV repair in Nairobi every single day, and most problems fall into a short list of recurring faults. Whether you own a Samsung, LG, Hisense, TCL, Vitron, or Von Hotpoint television, understanding what’s wrong before calling a technician can save you time and money. Below is our complete guide to the 20 most common TV faults we see across households in Nairobi and how our team fixes them.
1. No Power at All
If your TV won’t switch on and there’s no light on the standby button, the issue is usually a faulty power supply board (PSU), a blown fuse, or a damaged power cable. This is one of the most frequent TV repair Nairobi call-outs we receive from areas like Kasarani, Rongai, and Kahawa West.
2. TV Turns On But No Picture
A black screen with sound playing often points to a failed backlight or damaged LED strips inside the panel. This is common in older LED and LCD models and requires opening the panel to replace the backlight assembly.
3. Cracked or Broken Screen
Physical damage from falls, transportation, or impact results in a cracked screen, visible as spider-web lines or dark patches. Screen replacement cost depends on the panel size and brand availability in Nairobi.
4. Lines on the Screen
Horizontal or vertical lines usually indicate a damaged T-Con board (timing control board) or a loose ribbon cable connector. Vertical lines often mean panel damage, while horizontal lines point to a board-level fault.
5. Sound But No Picture
This points to backlight failure or a faulty main board, separate from the audio circuit. Our technicians isolate the fault using a signal generator before opening the unit.
6. Picture But No Sound
A dead speaker, blown audio IC, or software glitch after a firmware update can silence your TV. We test speakers directly and check audio output settings before replacing components.
7. TV Randomly Switches Off
Overheating, a failing capacitor on the power board, or a weak power supply causes TVs to shut down unexpectedly, especially during Nairobi’s warmer afternoons or in poorly ventilated cabinets.
8. TV Won’t Stay On (Keeps Restarting)
A capacitor fault on the motherboard or PSU is the usual culprit. Swollen or leaking capacitors are a visible giveaway our technicians check for first.
9. Remote Control Not Responding
Sometimes it’s simply dead batteries, but a damaged IR receiver sensor on the TV itself is a common internal fault, particularly after power surges.
10. HDMI Port Not Working
Loose, bent, or burnt-out HDMI ports prevent devices like DStv decoders, Fire Sticks, or laptops from connecting. We repair or replace faulty HDMI sockets on the mainboard.
11. No Signal Error Message
This is often mistaken for a TV fault but is usually caused by decoder issues, loose aerial or HDMI cables, or incorrect input source selection.
12. Discoloration or Color Distortion
Faded colors, a green or pink tint, or patches of wrong color usually trace back to a failing panel driver board or loose ribbon cables.
13. Flickering Screen
Flickering is commonly caused by an unstable power supply, failing capacitors, or a faulty backlight inverter in older CCFL-backlit models.
14. Frozen or Lagging Smart TV Apps
Smart TVs running YouTube, Netflix, or DStv Now can freeze due to insufficient storage, outdated firmware, or a failing internal memory chip. We perform software resets and firmware updates to resolve this.
15. Wi-Fi Connectivity Issues
Smart TVs losing connection to home networks often have a weak internal Wi-Fi module or need a network settings reset, an increasingly common request as more Nairobi homes use smart TVs for streaming.
16. Burnt Smell or Smoke
This is a serious electrical fault, usually a short circuit on the power board. Switch off immediately and unplug the TV to prevent fire risk, then call a technician.
17. TV Screen Has Dead or Stuck Pixels
Small, unchanging colored dots on the display indicate dead pixels on the LED panel. While minor cases are cosmetic, clusters may signal panel degradation.
18. Buzzing or Humming Noise
A faulty transformer or coil whine from the power supply produces an audible hum, particularly noticeable in quiet rooms at night.
19. Menu Settings Won’t Save
Corrupted firmware or a failing memory chip (EEPROM) can cause picture and sound settings to reset every time the TV is powered off, requiring a firmware reflash.
20. Water or Moisture Damage
TVs affected by rain, flooding, or spilled liquids need immediate professional cleaning and drying of internal components before power is reapplied, as moisture causes corrosion and short circuits over time.
