Detailed Repair Guide — LG TV Common Problems in Kenya

1. LG TV Won’t Turn On

Quick Fix: Check your power cable, wall socket, and try a hard reset (unplug for 60 seconds).

Estimated Cost: KES 1,500 – 5,000

What Causes This?

An LG TV that won’t power on is one of the most common complaints we receive at Refitec Kenya. In Kenya’s environment — with frequent power surges and fluctuating voltage — power boards are particularly vulnerable.

Common causes include:

• Blown main fuse — usually caused by power surges from Kenya Power
• Faulty power supply board — the most common hardware failure
• Damaged capacitors — swell or leak after years of use
• Defective HDMI-CEC settings — can prevent the TV from responding to the remote
• Damaged power cable or socket — always check this first

Step-by-Step Diagnosis

1. Check the power LED. When you press the power button, does the standby LED blink, flash red, or stay dark?
2. Try a different wall socket to rule out electrical faults.
3. Hard reset: Unplug the TV from the wall and hold the physical power button on the TV (not the remote) for 30 seconds. Plug back in after 1 minute.
4. Check for power surge damage. If Kenya Power recently had an outage or surge in your area, your power board may need replacement.
5. Listen for a click sound when pressing power — a click with no picture usually points to the main board or backlight.

If none of these work, the power supply board likely needs replacement. Contact Refitec Kenya on 0704843613 for a professional diagnosis.

2. Black Screen With Sound

Quick Fix: Shine a flashlight at the screen — if you can see a faint image, your backlight has failed.

Estimated Cost: KES 3,000 – 8,000

What Causes This?

This is a classic symptom of backlight failure — a very common LG TV problem in Kenya, particularly with LG LED TVs that are 3–7 years old.

Common causes include:

• Failed LED backlight strips — individual LEDs burn out over time
• Faulty inverter board — older LG TVs use inverter boards to power the backlight
• Damaged T-CON board — controls image processing; failure results in black screen
• Loose LVDS cable — the ribbon cable connecting the main board to the panel

Step-by-Step Diagnosis

1. Flashlight test: In a dark room, turn on the TV and shine a torch directly at the screen. If you can see a dim image, your backlight has failed — not the panel.
2. Check input source: Press the input/source button and try different HDMI ports.
3. Check for software issues: Try a factory reset via Settings > All Settings > General > Reset to Initial Settings.
4. Inspect the LVDS cable: If you’re technically confident, carefully inspect the ribbon cable at the back of the panel for loose connections.
5. Backlight strip replacement is a cost-effective repair. Refitec Kenya replaces individual LED strips without requiring a full panel replacement.

3. No Picture, No Sound

Quick Fix: Try unplugging all HDMI devices and perform a factory reset.

Estimated Cost: KES 4,000 – 10,000

What Causes This?

A completely dead LG TV — no picture and no sound — usually points to a main board failure or a severe power supply fault.

Common causes include:

• Failed main board (motherboard) — the central processing unit of the TV
• Dead power supply board — no power reaching the main board
• Software corruption — rare but possible after a bad firmware update
• Physical damage — from power surges, water, or impact

Step-by-Step Diagnosis

1. Check standby LED. If the red LED is on but the TV won’t start, the power board is likely working but the main board has failed.
2. Perform a factory reset using the physical buttons on the TV (not the remote).
3. Check for firmware issues. If the TV recently received an automatic update, it may have corrupted. LG firmware recovery via USB is possible.
4. Listen carefully for startup sounds — audio chips sometimes continue working even when video fails, helping isolate the fault.
5. If the TV is completely silent and dark with no LED activity, both the power board and main board may need inspection.

4. Screen Lines or Distorted Display

Quick Fix: Check your HDMI cables and try a different input — if lines appear on all sources, it’s a hardware fault.

Estimated Cost: KES 3,500 – 12,000

What Causes This?

Vertical or horizontal lines on an LG TV screen are a common and frustrating problem. The cost of repair depends heavily on whether it’s the T-CON board or the actual panel.

Common causes include:

• T-CON board failure — the most repairable cause (affordable fix)
• Loose or damaged LVDS/flex cable — causes partial line patterns
• Panel damage — cracked or pressure-damaged panels (most expensive to fix)
• Physical impact — dropped TV or objects hitting the screen

Step-by-Step Diagnosis

1. Identify the pattern of lines. Vertical lines often indicate T-CON board or panel issues. Horizontal lines may point to LVDS cable faults.
2. Test with different inputs. Connect a laptop or phone via HDMI. If lines appear on all sources, it’s internal hardware — not the source device.
3. Gently flex the back of the screen. If lines temporarily disappear or shift, a loose ribbon cable is likely the cause.
4. Check for impact damage. If the lines form a spider-web or irregular pattern spreading from one corner, the panel is cracked internally and needs full replacement.
5. T-CON board replacement is significantly cheaper than panel replacement and resolves the majority of line problems.

⚠️ Panel replacement for LG TVs can cost KES 15,000–40,000+ depending on screen size. Refitec Kenya will always advise you honestly whether repair is cost-effective.

5. LG TV Remote Not Working

Quick Fix: Replace the batteries first. Then clean the IR sensor on the TV with a soft cloth.

Estimated Cost: KES 500 – 2,000

What Causes This?

Remote control issues are often the simplest LG TV problems to fix — but occasionally indicate a sensor fault.

Common causes include:

• Dead or weak batteries — the most common cause by far
• Blocked IR sensor — dust, direct sunlight, or objects blocking the sensor at the bottom of the TV
• Damaged remote control — physical damage or liquid spills
• Faulty IR receiver on the TV — requires professional repair
• LG Magic Remote pairing lost — needs re-pairing

Step-by-Step Diagnosis

1. Replace the batteries with fresh AA batteries. Use quality batteries (not old stock).
2. Test with a smartphone camera. Point your remote at your phone camera and press a button — you should see a purple/white flash from the IR bulb if the remote is working.
3. Clean the IR sensor on the front of the TV using a slightly damp cloth. Ensure no furniture or soundbars are blocking it.
4. Re-pair LG Magic Remote: Hold the home and back button simultaneously for 5 seconds while pointing at the TV.
5. Test the LG ThinQ app as an alternative remote — available on Android and iOS — to isolate whether the fault is the remote or the TV’s receiver.

6. LG Smart TV Not Connecting to Wi-Fi

Quick Fix: Restart your router AND your TV. Then forget the network and reconnect.

Estimated Cost: KES 1,000 – 4,500 (if hardware fault)

What Causes This?

Wi-Fi issues on LG Smart TVs are common in Kenya, especially with older models or after software updates.

Common causes include:

• Router compatibility issues — especially with newer 5GHz-only routers
• Corrupted network settings — requires a network reset
• Failed Wi-Fi module — internal hardware fault (requires board repair)
• Outdated firmware — old firmware may not support current network security protocols
• DNS or IP conflict — common in homes with many connected devices

Step-by-Step Diagnosis

1. Restart both the TV and router. Unplug both for 30 seconds before restarting.
2. Forget the Wi-Fi network on the TV: Settings > Network > Wi-Fi Connection > select your network > Forget.
3. Check your router band. LG TVs (especially models before 2018) may only support 2.4GHz. Log into your router and ensure 2.4GHz is enabled.
4. Set a manual DNS. Go to Settings > Network > Wi-Fi Connection > Advanced Settings > set DNS to 8.8.8.8 (Google DNS).
5. Factory reset the network settings if all else fails: Settings > All Settings > General > Reset Network Settings.
6. If the TV still won’t connect, the internal Wi-Fi module may have failed and requires replacement.

7. LG TV Sound but No Picture (Dim Screen)

Quick Fix: In a dark room, shine a flashlight at the screen. A faint image confirms backlight failure.

Estimated Cost: KES 3,000 – 7,500

What Causes This?

This is almost always a backlight fault — one of the most common LG TV repairs in Kenya. The panel itself is fine, making this a cost-effective repair.

Common causes include:

• Dead LED backlight strips — individual LEDs fail over time
• Faulty backlight driver on the power board
• Open-circuit backlight connector — loose cable between board and strips

Step-by-Step Diagnosis

1. Confirm with the flashlight test (see Section 2 above).
2. Note whether any area of the screen is brighter than others. Uneven brightness (cloudy patches) indicates specific LED strip failures.
3. Check screen brightness settings — ensure the picture settings haven’t been set to minimum accidentally.
4. Professional LED strip replacement at Refitec Kenya is affordable and typically completed within 1–2 days. We replace only the failed strips rather than the entire backlight assembly where possible.

8. Overscan / Picture Cut Off

Quick Fix: Go to Settings > Picture > Aspect Ratio > Set to “Just Scan” or “Screen Fit.”

Estimated Cost: Free (settings fix) – KES 2,000

What Causes This?

Overscan — where the picture extends beyond the visible screen edges — is almost always a settings issue on LG TVs.

Step-by-Step Fix

1. Press the Settings button on your LG remote.
2. Navigate to Picture > Aspect Ratio Settings.
3. Change the aspect ratio to “Just Scan” or “1:1”.
4. If using an external device, check the output resolution settings on that device (set HDMI output to match your TV’s native resolution).
5. For LG webOS TVs, go to Settings > Picture > Picture Mode Settings > Picture Options > HDMI Ultra HD Deep Colour — toggle this on for the HDMI port you’re using.

9. LG OLED Burn-In

Quick Fix: Run LG’s built-in Pixel Refresher tool (Settings > OLED Care > Pixel Refresher) for minor cases.

Estimated Cost: KES 15,000 – 50,000+ (panel replacement for severe cases)

What Causes This?

LG OLED TVs are premium displays, but their organic pixels can permanently degrade when static images are displayed for extended periods — a phenomenon known as burn-in.

Common causes in Kenya include:

• Watching one TV channel with a permanent logo for long periods
• Using the TV as a desktop monitor with a static taskbar
• Gaming with a fixed HUD overlay for many hours

Step-by-Step Prevention & Treatment

1. Run Pixel Refresher: Settings > OLED Care > Device Self Care > Pixel Refresher. This takes approximately 1 hour and should be run monthly on heavily used TVs.
2. Enable Screen Shift: Settings > OLED Care > Care Picture Settings > Screen Shift — this subtly moves the image to prevent static burn.
3. Reduce brightness for everyday TV watching. Lower brightness significantly extends OLED lifespan.
4. Enable Auto Pixel Refresh — this runs automatically when the TV is switched off after 4+ hours of use.
5. For severe burn-in, panel replacement is the only solution. Contact Refitec Kenya for an honest assessment — we will always advise you on whether replacement is economically justified for your TV size and model.

10. LG TV Freezing or Lagging

Quick Fix: Clear the TV’s memory cache and uninstall unused apps.

Estimated Cost: KES 1,000 – 3,500

What Causes This?

Freezing and sluggish performance on LG Smart TVs is common in older webOS models as apps become more demanding over time.

Common causes include:

• Overloaded internal memory — too many installed apps
• Outdated firmware — older software struggling with newer app requirements
• Corrupted app data or cache
• Overheating — poor ventilation in TV cabinet setups

Step-by-Step Fix

1. Clear app cache: Settings > Support > Additional Settings > Device Self Diagnosis > Clear Cache (available on webOS 6.0 and above).
2. Delete unused apps: Home > Apps > Edit — remove any apps you don’t use regularly.
3. Update firmware: Settings > Support > Software Update > Check for Updates.
4. Factory reset as a last resort: Settings > All Settings > General > Reset to Initial Settings. Note: this will remove all your accounts and settings.
5. Improve ventilation. Ensure the TV has at least 10cm of clearance on all sides. Overheating causes significant performance degradation and hardware damage.
6. If freezing persists after a factory reset, the eMMC storage chip on the main board may be degrading and require professional replacement.
