⚡ Common TV Problems and Their Solutions

1. TV Not Powering On

Cause:

• Blown internal fuse due to a power surge.
• Faulty power supply board capacitors.
• Damaged mainboard or defective standby circuit.
• Loose AC input connections.

Technical Breakdown:
Modern TVs rely on a switch mode power supply (SMPS) that converts AC from the socket into stable DC voltages (3.3V, 5V, 12V, 24V). If the primary capacitor fails or the MOSFETs in the power supply burn out, the TV will not power on.

Solution:

• Test with a multimeter to check AC input continuity.
• Replace blown fuses and test rectifier diodes.
• Inspect and replace swollen electrolytic capacitors.
• If the power supply board is beyond repair, replace with a genuine spare part (available at Refitec).

Maintenance Tip:
Always use a surge protector in Avenue Park Estate, where occasional power fluctuations occur, to protect your TV’s delicate circuits.

2. No Picture but Sound is Present

Cause:

• Backlight failure in LED TVs.
• Faulty T-Con (Timing Control) board.
• Loose LVDS cable connecting the mainboard to the display.

Technical Breakdown:
LED TVs use LED strips behind the LCD panel. If one or more strips burn out, the screen will appear black, even though sound continues. The T-Con board controls pixel activation; failure leads to no image or distorted visuals.

Solution:

• Shine a flashlight close to the screen; if you see faint images, it’s a backlight issue.
• Replace damaged LED strips.
• Replace or repair the T-Con board.
• Reseat or replace the LVDS ribbon cable.

Maintenance Tip:
Reduce backlight brightness settings to extend LED strip life.

3. No Sound but Picture is Present

Cause:

• Damaged audio IC (integrated circuit).
• Faulty internal speakers.
• Software/firmware corruption.
• Muted audio settings or incorrect input mode.

Technical Breakdown:
The audio IC amplifies sound signals from the mainboard. When it overheats or fails, no sound reaches the speakers.

Solution:

• Test with external speakers or headphones.
• Reflash or update firmware.
• Replace faulty speakers or audio IC.

Maintenance Tip:
Avoid playing your TV at maximum volume for long hours; it stresses the audio IC and speakers.

4. TV Turns On and Off Repeatedly (Power Cycling)

Cause:

• Faulty capacitors on the mainboard or power supply.
• Incomplete firmware update.
• Short circuit in inverter or LED backlight system.

Technical Breakdown:
A TV’s microcontroller constantly monitors power. If unstable voltages are detected, the TV restarts to protect itself. This is common in Samsung, LG, and Sony smart TVs.

Solution:

• Replace bulging capacitors.
• Reflash TV firmware via USB.
• Replace shorted LED strips.

Maintenance Tip:
Do not unplug your TV during software updates.

5. Lines on the Screen (Vertical/Horizontal)

Cause:

• Loose or damaged ribbon cable connections.
• Defective T-Con board.
• Dead pixels or panel damage.

Technical Breakdown:
Ribbon cables transmit pixel data. If they loosen due to heat, pressure, or aging, lines appear. T-Con board faults can cause half-screen images or multiple colored lines.

Solution:

• Reseat ribbon cables.
• Replace T-Con board.
• If the LCD/LED panel is damaged, replacement may be necessary (Refitec stocks original panels).

Maintenance Tip:
Keep your TV in a dust-free, cool environment to prevent static damage to the T-Con board.

6. TV Remote Not Working

Cause:

• Dead batteries.
• Faulty IR receiver in the TV.
• Remote control circuit damage.

Solution:

• Replace batteries.
• Test remote with a phone camera (IR light should flash).
• Replace TV’s IR receiver or remote control.

Maintenance Tip:
Avoid dropping the remote, as internal circuit boards are fragile.

7. TV Has No Signal / HDMI Port Issues

Cause:

• Faulty HDMI port or input board.
• Loose antenna cables.
• Corrupted TV firmware.

Solution:

• Clean HDMI ports with isopropyl alcohol.
• Replace faulty HDMI input ports.
• Update TV firmware.

Maintenance Tip:
Use high-quality HDMI cables; cheap ones can damage input ports.

8. Distorted or No Color Display

Cause:

• Faulty T-Con board.
• Incorrect picture settings.
• Panel damage.

Solution:

• Perform a factory reset.
• Replace T-Con board if colors remain distorted.
