Modern smart TVs have revolutionized home entertainment, but they come with their own set of technical challenges. Whether you’re dealing with connectivity issues, screen problems, or software glitches, understanding common smart TV problems and their repair solutions can save you time and money.
Common Smart TV Problems and Their Solutions
1. No Power or Won’t Turn On
This is one of the most frustrating issues. Before calling a technician, check if the power cable is properly connected and try a different outlet. If the standby light is on but the TV won’t power up, the issue might be with the power supply board.
Repair cost: KES 3,000 – KES 8,000 depending on the board replacement needed.
2. Internet Connectivity Problems
Smart TVs rely heavily on internet connection. If your TV keeps disconnecting from Wi-Fi, start by restarting your router and TV. Check if other devices connect properly to rule out router issues. Navigate to network settings and forget the network, then reconnect with your password.
If problems persist, the Wi-Fi module might need replacement, costing around KES 4,000 – KES 10,000.
3. Screen Issues: Lines, Cracks, or Black Spots
Vertical or horizontal lines on your screen typically indicate a panel problem or loose connections. Black spots might suggest backlight issues, while physical cracks require complete screen replacement.
Screen replacement costs vary significantly: KES 15,000 – KES 50,000+ depending on TV size and brand.
4. No Sound or Audio Problems
Check your audio settings first and ensure the TV isn’t muted or set to external speakers. If internal speakers have failed, replacement typically costs KES 2,500 – KES 6,000.
5. Apps Crashing or Freezing
Smart TV apps can become unresponsive due to outdated software or insufficient memory. Clear the app cache through settings, uninstall unused apps, and ensure your TV’s firmware is updated. A factory reset often resolves persistent software issues, but back up your settings first.
Software troubleshooting by a technician: KES 1,500 – KES 3,000.
6. HDMI Port Not Working
Test with different HDMI cables and devices first. If specific ports don’t work, the HDMI board might need replacement, costing KES 3,500 – KES 8,000.
7. Remote Control Issues
Before assuming the TV is faulty, replace remote batteries and check for obstructions between the remote and TV sensor. If the remote still doesn’t work, a replacement remote costs KES 800 – KES 3,500 depending on whether you choose universal or original remotes.
8. Picture Quality Problems
Adjust picture settings including brightness, contrast, and color. Enable motion smoothing for sports and disable it for movies. If adjustments don’t help and you see discoloration or dimming, the LED backlight strips might need replacement at KES 5,000 – KES 12,000.
When to Call a Professional
While some troubleshooting can be done at home, certain repairs require professional expertise. Call a technician if you encounter:
- Physical damage to the screen
- Electrical burning smells
- Repeated automatic shutdowns
- Main board failures
- Complex software issues that persist after factory reset
Typical Service Call Charges in Kenya

Preventive Maintenance Tips
Extend your smart TV’s lifespan with these practices:
- Use a surge protector to prevent electrical damage (cost: KES 800 – KES 3,000)
- Keep ventilation areas clear to prevent overheating
- Update software regularly
- Clean the screen with microfiber cloths, never harsh chemicals
- Avoid leaving static images on screen for extended periods to prevent burn-in
Choosing the Right Repair Service
Look for technicians with experience in your TV brand. Ask about warranty on repairs (typically 1-3 months for parts and labor). Get written quotations before authorizing major repairs. For TVs still under manufacturer warranty, contact authorized service centers first.
DIY vs Professional Repair
Simple fixes like cable connections, software updates, and settings adjustments are safe to attempt yourself. However, opening the TV case voids warranties and risks electric shock or further damage. Component-level repairs should always be left to qualified technicians.
Conclusion
Smart TV repair solutions range from simple troubleshooting to complex component replacement. Understanding these common problems helps you make informed decisions about whether to attempt fixes yourself or call a professional. Regular maintenance and prompt attention to small issues can prevent costly repairs down the line. When repair costs approach 50-60% of a new TV’s price, replacement might be more economical than repair.
For persistent problems, consult certified technicians who can accurately diagnose and repair your smart TV using proper tools and genuine parts.
