Tip 1: TV Won’t Turn On — What To Do First

Quick Fix: Unplug the TV from the wall socket, wait 60 seconds, then plug it back in. Check that your power extension or surge protector is working by testing another device on it.

Detailed Steps

A TV that refuses to power on is one of the most common complaints we receive at our Nairobi repair centre. Before assuming the worst, work through these steps systematically.

Step 1 — Check Your Power Source Plug the TV directly into a wall socket rather than an extension or surge protector. Nairobi’s power supply can be inconsistent, and a faulty extension board is often the hidden culprit. If the TV powers on when plugged directly into the wall, replace your extension.

Step 2 — Inspect the Power Cable Look for any visible damage along the entire length of the cable — cuts, fraying, or a bent connector at the TV end. A damaged cable is a fire hazard and must be replaced immediately. Refitec Kenya stocks compatible power cables for most TV brands including Samsung, LG, Sony, and Skyworth.

Step 3 — Perform a Hard Reset Unplug the TV from the power source entirely. While it is unplugged, press and hold the physical power button on the TV (not the remote) for 30 seconds. This drains any residual power from the capacitors. Plug the TV back in and try turning it on.

Step 4 — Test the Remote Control A failing remote can make it seem like the TV won’t respond. Replace the batteries with fresh ones, or try turning the TV on using the physical button on the unit itself. If the TV powers on directly but not via remote, the issue is with the remote, not the TV.

Step 5 — Check for Indicator Light Behaviour Does the standby light blink? Different blink patterns indicate different internal faults. On many Samsung and LG TVs, a blinking red standby light signals a power board fault or backlight failure. Note how many times it blinks and contact Refitec Kenya — we can often diagnose the issue remotely from the blink code.

When To Call a Professional: If the TV shows no indicator light at all after the above steps, the power supply board may have failed. This is a common and very repairable fault at our Nairobi workshop.


Tip 2: No Picture But Has Sound — Diagnose the Display Issue

Quick Fix: Press the “Source” or “Input” button on your remote to confirm you’re on the correct input channel. Then go to Menu > Picture > Backlight and ensure the backlight is not set to zero.

Detailed Steps

Hearing audio but seeing a black screen is a very specific symptom that actually narrows the problem down considerably. In most cases, the TV’s main board is working fine.

Step 1 — Verify the Input Source Press the Source or Input button on your remote. Cycle through HDMI 1, HDMI 2, AV, and other inputs. It’s surprisingly common for a TV to switch input accidentally, especially with universal remotes or after a power outage.

Step 2 — Check the Backlight Setting Navigate to Menu > Picture Settings > Backlight. If someone has manually turned the backlight to 0, the screen will appear completely black even though the TV is functioning normally. Increase the backlight value and the picture should return immediately.

Step 3 — Shine a Torch on the Screen In a dark room, shine a flashlight or your phone torch directly at the screen. If you can faintly see a picture, the backlight has failed but the panel itself is intact. This is a very common and repairable fault — Refitec Kenya replaces LED backlights for most TV brands at competitive prices in Nairobi.

Step 4 — Inspect HDMI and AV Cables A faulty HDMI cable or loose connection on your DSTV box or streaming device can cause a black screen. Swap the HDMI cable for a new one, or test a different HDMI port on the TV.

Step 5 — Test Without External Devices Disconnect all external devices and access the TV’s built-in smart TV interface. If a picture appears when no devices are connected, the fault lies with a connected device, not the TV itself.

When To Call a Professional: If the torch test confirms the panel is faintly displaying an image but backlights are dead, do not attempt to replace LEDs yourself. Improper handling can crack the panel, making the repair significantly more expensive.


Tip 3: No Sound But Has Picture — Fixing Audio Problems

Quick Fix: Press the Mute button on your remote once, then check the volume level. Go to Menu > Sound > Audio Output and confirm the output is set to “TV Speakers” rather than a Bluetooth device or ARC output.

Detailed Steps

A TV with a perfect picture but no audio is almost always caused by a settings conflict, a muted output, or an external audio device issue — not a hardware failure.

Step 1 — Rule Out the Obvious Check that the TV is not muted. Press the mute button on the remote and raise the volume to at least 20 before testing. This solves the problem more often than you’d expect.

Step 2 — Check Audio Output Settings Go to Menu > Sound > Audio Output or Speaker Settings. Smart TVs — especially Samsung and LG models popular across Nairobi — automatically switch audio output to a Bluetooth speaker or soundbar once one has been paired. If that device is off or out of range, you’ll hear nothing. Set the output back to “Internal TV Speakers.”

Step 3 — Test with Headphones Plug headphones into the TV’s headphone jack if available. If you hear sound through the headphones, the internal speakers have failed but the audio processing hardware is working fine. Internal speaker replacement is a straightforward and affordable repair.

Step 4 — Feel for Speaker Vibration Turn the volume up and place your hand lightly near the speaker grilles on the back or side of the TV. You should feel a slight vibration. No vibration at high volume suggests either a blown speaker or a disconnected internal speaker cable.

Step 5 — Run the Built-In Sound Test Most smart TVs have a self-diagnostic sound test. On Samsung TVs, go to Settings > Support > Device Care > Self Diagnosis > Sound Test. This isolates the fault to either the hardware or the content source.

When To Call a Professional: If the sound test fails or speakers produce crackling, distorted, or one-sided audio, Refitec Kenya can replace individual speakers or the audio output board at our Nairobi workshop.


Tip 4: Blurry, Pixelated, or Distorted Picture — Improving Image Quality

Quick Fix: Test the TV on a different source — play a video from a USB drive or open a streaming app. If the picture is clear on streaming but poor on cable or satellite, the fault is with your signal provider, not your TV.

Detailed Steps

Poor picture quality is frustrating, but it is rarely a sign of a broken TV. In Nairobi, unstable antenna signals and low-quality HDMI cables are the two most frequent culprits.

Step 1 — Identify When the Problem Occurs Test the TV across multiple sources — DSTV, Zuku, YouTube, and a USB video file. If blurry or pixelated images appear on one source only, the TV itself is likely fine and the fault lies with that signal or device.

Step 2 — Replace HDMI Cables Low-quality or old HDMI cables cause fuzzy images, colour distortion, and flickering lines. Many cheap HDMI cables available in Nairobi’s electronics shops are substandard. Replace with a verified HDMI 2.0 cable, particularly if you’re running a 4K TV.

Step 3 — Reset Picture Settings to Default Navigate to Menu > Picture and restore factory defaults. Then fine-tune: reduce sharpness to between 20–40%, set colour temperature to “Warm” or “Standard”, and disable processing features such as Motion Smoothing or Dynamic Contrast if the image looks unnatural.

Step 4 — Consider Your Content Resolution Many free-to-air digital channels in Nairobi broadcast in Standard Definition. On a large 4K TV, SD content will naturally appear soft. This is not a TV fault — it is a limitation of the broadcast quality itself.

Step 5 — Inspect the Panel for Physical Damage Examine the screen closely in good light. Clusters of dead pixels, large discoloured patches, or horizontal/vertical lines running across the screen indicate physical panel damage — often caused by impact or rough handling during moving.

When To Call a Professional: Refitec Kenya will assess damaged panels and advise honestly whether repair is economically worthwhile relative to a replacement unit.


Tip 5: TV Keeps Turning Off Randomly — Stopping Unexpected Shutdowns

Quick Fix: Go to Menu > System > Time > Sleep Timer and turn it off. Also check Menu > General > Eco Solution > Auto Power Off and disable it.

Detailed Steps

A TV that switches itself off after 30 minutes, 1 hour, or 4 hours is almost always responding to a built-in timer — not experiencing a hardware fault. These settings are frequently activated by accident.

Step 1 — Disable the Sleep Timer Go to Menu > System > Time > Sleep Timer (or Menu > General > System Manager > Time on Samsung models). If a timer is active, the TV will shut itself off after the set period. Switch it to “Off.”

Step 2 — Disable Auto Power Off Navigate to Menu > General > Eco Solution > Auto Power Off or Menu > Settings > System > Power > Auto Power Off. This setting turns the TV off after extended inactivity — usually 4 hours. Useful for energy saving, but commonly mistaken for a fault.

Step 3 — Check for Overheating Feel the back panel immediately after the TV shuts off. If it is very hot, the TV is overheating and powering down to protect itself. Ensure at least 10cm of clearance on all sides and avoid enclosed TV cabinets without airflow. Dust build-up inside the TV is a common overheating cause in Nairobi’s environment — Refitec Kenya offers internal cleaning and thermal servicing.

Step 4 — Update the TV Firmware Outdated software can cause random shutdowns on smart TVs. Go to Menu > Support > Software Update > Update Now. Connect the TV to Wi-Fi first. Firmware updates frequently resolve bugs behind unexpected behaviour.

Step 5 — Address Power Supply Instability Nairobi experiences regular power fluctuations. A TV receiving inconsistent voltage will shut down as a protective measure. Investing in an Automatic Voltage Regulator (AVR) or UPS is strongly recommended — Refitec Kenya can advise on the right specification for your TV’s power requirements.

When To Call a Professional: If the TV shuts off immediately on startup, shuts off with a burning smell, or runs extremely hot despite adequate ventilation, stop using it immediately and contact Refitec Kenya. A failing capacitor or power board poses a real fire risk if left unaddressed.
