Common TV Problems and Their Solutions
1. TV Not Powering On
Technical Explanation:
When a TV doesn’t power on, the issue could be linked to the power supply board, motherboard, fuse, or power IC (integrated circuit). The power supply converts high-voltage AC into low-voltage DC that the TV circuits can use. If the capacitors bulge, resistors burn, or the fuse blows, your TV will not start.
Diagram Style Breakdown:
- Power Cord → Fuse → Rectifier → Filter Capacitors → Voltage Regulators → Mainboard
If any point in this chain fails, the TV remains dead.
Solutions by Refitec:
- Checking the power board and replacing faulty capacitors.
- Replacing blown fuses with the correct rating.
- Testing the motherboard and repairing damaged ICs.
- Using genuine replacement parts available at Refitec.
Maintenance Tips:
- Always connect your TV through a surge protector.
- Avoid plugging/unplugging the power cord repeatedly.
- Keep your house wiring safe to avoid power surges.
2. Broken or Cracked TV Screen
Technical Explanation:
TV screens are made of fragile LCD/LED glass panels. A small crack or impact can damage the liquid crystal or LED backlight array, making the screen display black spots, colored lines, or go completely blank. Unfortunately, screen replacement is the only solution in most cases.
Solutions by Refitec:
- We replace cracked screens with genuine OEM panels for all TV brands.
- If the screen is partially damaged, we assess if the backlight or T-con board can be repaired instead of a full replacement.
- Affordable replacement options are available, depending on the brand and size.
Maintenance Tips:
- Mount your TV securely on the wall using a strong bracket.
- Keep children and objects away from the TV area.
- Clean the screen gently with a microfiber cloth to avoid scratches.
3. No Sound but Picture Available
Technical Explanation:
When your TV displays images but has no sound, the fault usually lies in the audio IC, sound amplifier circuit, speakers, or the software. Sometimes, incorrect settings like “mute mode” or “external speaker mode” cause this.
Diagram Style Breakdown:
- Motherboard → Audio IC → Amplifier → Speaker Drivers → Sound Output
Solutions by Refitec:
- Checking TV settings before hardware diagnosis.
- Testing and replacing faulty audio ICs or amplifiers.
- Replacing blown speakers with genuine spare parts.
- Updating firmware to fix software-related audio issues.
Maintenance Tips:
- Avoid overloading your TV’s volume settings for long periods.
- Connect external speakers correctly to prevent short circuits.
4. TV Has Sound but No Picture
Technical Explanation:
This issue is commonly caused by a faulty backlight system, T-Con board, or display driver ICs. The backlight provides illumination, while the T-con board processes image signals from the motherboard.
Solutions by Refitec:
- Replacing faulty LED strips in the backlight.
- Repairing or replacing the T-con board.
- Diagnosing and repairing screen driver circuits.
Maintenance Tips:
- Reduce brightness settings to prolong backlight life.
- Allow ventilation behind the TV to avoid overheating.
5. TV Turns On and Off by Itself
Technical Explanation:
This auto power cycle problem can stem from faulty capacitors, overheating, loose cables, or software glitches. Some TVs even reboot when the mainboard detects unstable voltage.
Solutions by Refitec:
- Checking and replacing faulty capacitors.
- Repairing overheating issues with proper cooling.
- Updating or reinstalling TV firmware.
- Tightening loose internal connections.
Maintenance Tips:
- Keep your TV dust-free.
- Update software regularly.
- Use stable electricity sources.
6. Horizontal or Vertical Lines on Screen
Technical Explanation:
Lines on the screen usually indicate a faulty T-con board, damaged screen ribbon cables, or defective display drivers. If the screen is cracked, the lines are permanent.
Solutions by Refitec:
- Replacing or repairing the T-con board.
- Reseating or replacing ribbon cables.
- If panel damage is severe, replacing the screen.
Maintenance Tips:
- Handle the TV carefully when moving it.
- Protect it from moisture that corrodes ribbon connectors.
7. TV Remote Control Not Working
Technical Explanation:
The problem may not always be the TV—it could be the remote’s IR (infrared) sensor, dead batteries, or receiver circuit in the TV.
Solutions by Refitec:
- Testing and repairing the TV’s IR sensor.
- Repairing or replacing faulty remotes.
- Supplying universal or brand-specific remote replacements.
Maintenance Tips:
- Keep remotes dry and clean.
- Replace batteries in pairs to avoid leakage.
8. TV HDMI or AV Ports Not Working
Technical Explanation:
Ports wear out due to frequent plugging/unplugging, causing loose connections or burnt circuits.
Solutions by Refitec:
- Re-soldering loose HDMI/AV ports.
- Replacing damaged input boards.
- Testing compatibility with external devices.
Maintenance Tips:
- Use quality cables.
- Avoid forcing plugs into ports.
