🔍 Detailed Guide: Sony TV Problems, Causes & Repair Costs in Kenya
1. Sony TV Won’t Turn On
Estimated Cost: KES 2,500 – 6,000
This is one of the most common Sony TV complaints in Kenya. You press the power button and nothing happens — no light, no sound, no picture.
Common Causes:
- Faulty power supply board — the most frequent culprit, especially in older Bravia models
- Blown capacitors on the power board (very common due to power surges in Kenya)
- Damaged backlight driver
- Faulty standby circuit
What electronicsrepair Does: Our technicians perform a full power board diagnostic, test the capacitors and voltage rails, and replace only the faulty components. In many cases, a board-level repair (replacing blown capacitors) is significantly cheaper than a full board replacement.
Pro Tip: If your Sony TV shows a red standby light but doesn’t turn on when you press power, the issue is almost always internal — do not keep pressing the remote as this can worsen the fault.
2. Sony TV Black Screen But Sound Works
Estimated Cost: KES 3,000 – 8,000
You can hear audio and the TV appears to be on, but the screen is completely black. This is a very common Sony Bravia issue.
Common Causes:
- Failed backlight strips (LED backlights burn out over time)
- Faulty T-Con (Timing Control) board
- Loose internal ribbon cable connections
- Inverter board failure (on older CCFL-backlit models)
What electronicsrepair Does: We test whether the backlight is functional using a flashlight test. If the backlight has failed, we replace the LED strips with compatible Kenya-sourced parts. If the T-Con board is faulty, we replace or repair it.
Pro Tip: Shine a torch close to your Sony TV screen in a dark room — if you can faintly see an image, your backlight has failed and the repair is straightforward and affordable.
3. Sony TV Has No Sound But Picture Is Fine
Estimated Cost: KES 2,000 – 5,000
The picture displays normally but there is no sound at all, or sound cuts in and out intermittently.
Common Causes:
- Blown internal speakers
- Faulty audio output IC chip on the main board
- Damaged audio ribbon cable
- Software audio settings glitch (less common)
What electronicsrepair Does: We test the speaker output and audio IC to pinpoint whether the fault is in the speakers, the amplifier circuit, or the main board. Speaker replacements are inexpensive and quick.
4. Sony TV Flickering or Distorted Picture
Estimated Cost: KES 3,500 – 9,000
The picture flickers, has a rolling effect, displays double images, or appears distorted.
Common Causes:
- T-Con board failure — this board controls how the image is displayed on the panel
- Main board fault
- Loose panel ribbon cables (common after TV has been moved or dropped)
- Power fluctuations causing board damage
What electronicsrepair Does: We reseat all ribbon cables first (sometimes resolves the issue at no cost beyond diagnosis), then test the T-Con and main boards systematically.
Pro Tip: Flickering that gets worse when the TV heats up is almost always a capacitor issue on the main board — a relatively affordable fix.
5. Sony TV Stuck on Logo Screen / Won’t Boot Past Sony Logo
Estimated Cost: KES 1,500 – 3,500
Your Sony Android TV or Bravia turns on, shows the Sony logo, then freezes and won’t load the home screen.
Common Causes:
- Corrupted firmware or software update that failed mid-installation
- Flash memory chip fault
- Corrupted system files due to a power cut during update
What electronicsrepair Does: We perform a firmware reflash using official Sony firmware files. In most cases this resolves the issue completely without replacing any hardware. For severe flash memory faults, the eMMC chip may need to be replaced.
6. Sony TV HDMI Ports Not Working
Estimated Cost: KES 2,500 – 5,500
One or more HDMI ports on your Sony TV stop detecting devices (decoders, laptops, gaming consoles, etc.).
Common Causes:
- Physically damaged HDMI port (bent pins from improper cable insertion)
- Faulty HDMI IC chip on the main board
- ESD (electrostatic discharge) damage from connected devices
What electronicsrepair Does: We inspect ports visually and test each HDMI input. Damaged ports can be desoldered and replaced. If the HDMI controller chip is faulty, we replace the chip at board level.
7. Sony Android TV Running Slow or Freezing
Estimated Cost: KES 1,000 – 3,000
Your Sony Android TV takes a long time to load, apps crash frequently, or the interface is sluggish and unresponsive.
Common Causes:
- Insufficient storage space (apps fill up the internal memory)
- Outdated firmware
- Corrupted cache files
- Rarely, a failing eMMC storage chip
What electronicsrepair Does: We clear system caches, uninstall unnecessary apps, update firmware to the latest stable version, and if necessary perform a factory reset while backing up your settings. For hardware storage faults, we replace the eMMC chip.
8. Sony TV Wi-Fi Not Connecting / Internet Issues
Estimated Cost: KES 1,500 – 4,000
Your Sony Smart TV or Android TV won’t connect to Wi-Fi, drops connection frequently, or cannot access the internet even when connected.
Common Causes:
- Outdated firmware with Wi-Fi bugs (very common on Sony Android TVs)
- Faulty Wi-Fi module
- Router compatibility issues
- IP/DNS configuration problems
What electronicsrepair Does: We diagnose whether the fault is software (firmware update / reset) or hardware (Wi-Fi module replacement). Most Wi-Fi issues on Sony TVs are resolved through a firmware update or network reset.
9. Sony TV Remote Not Working
Estimated Cost: KES 500 – 2,000
The Sony remote does not respond, or the TV doesn’t react even when you point the remote directly at it.
Common Causes:
- Dead or low remote batteries
- Faulty IR (infrared) sensor on the TV
- Damaged remote control PCB
- IR signal blocked by a cover or casing
What electronicsrepair Does: We test the IR sensor on the TV using a phone camera (which can detect IR light). If the sensor is faulty, we replace it. We also repair or replace remote controls.
10. Lines on Sony TV Screen (Vertical or Horizontal)
Estimated Cost: KES 4,000 – 15,000+
Thin or thick lines appear on the screen, either running vertically or horizontally across the display.
Common Causes:
- T-Con board failure (most common and repairable)
- Damaged panel ribbon cables
- Physical damage to the LCD/OLED panel itself (expensive — may require panel replacement)
What electronicsrepair Does: We first establish whether the lines are caused by the T-Con board or the panel itself. T-Con repairs are affordable. If the panel is physically cracked or damaged, we provide an honest cost assessment — in some cases, panel replacement may not be economically viable and we will advise accordingly.
Important: Lines that appear only on part of the screen and change when you flex the screen frame suggest a cable fault — affordable to repair. Lines that are fixed and accompanied by physical screen damage suggest panel damage — more expensive.
11. Sony TV Overheating or Shutting Down on Its Own
Estimated Cost: KES 2,000 – 5,000
Your Sony TV switches off by itself after some time, or the back of the TV becomes excessively hot.
Common Causes:
- Blocked ventilation vents (dust accumulation — very common in Nairobi homes)
- Failing capacitors on the power or main board
- Faulty internal cooling components
- TV mounted flush against a wall with no airflow
What electronicsrepair Does: We open the TV, clean all internal vents and heatsinks, test all capacitors, and replace any that show signs of failure. We also advise on proper TV placement to prevent recurrence.
Pro Tip: Sony TVs should have at least 10cm of clearance on all sides when wall-mounted. Mounting a TV in an enclosed cabinet without ventilation is a leading cause of overheating in Kenya.
12. Sony TV Colour Problems (Wrong Colours, Faded, or Greenish/Reddish Tint)
Estimated Cost: KES 2,500 – 7,000
The TV picture has unnatural colours — a green, red, or blue tint — or colours appear washed out and faded.
Common Causes:
- Main board failure (colour processing fault)
- Loose or damaged panel ribbon cables
- Panel degradation (more common in older TVs)
- Incorrect picture settings (user-level issue — check first)
What electronicsrepair Does: We first verify the issue isn’t a settings problem (Picture Mode, Colour Space settings). If hardware-related, we test the main board and all cable connections, replacing or repairing as needed.
