1. TV Screen Problems – Cracks, Lines, and Dead Pixels

Common Issues:

• Cracked or physically damaged screen.
• Vertical or horizontal colored lines.
• Dead pixels appearing as black or white dots.
• Flickering screen or ghost images.

Technical Explanation:

TV screens (LCD, LED, OLED, and QLED) are built with delicate layers of liquid crystals or organic light-emitting diodes. When a screen gets damaged, either through impact or electrical failure, signals from the T-CON board (Timing Controller Board) fail to reach the panel uniformly. This results in distorted images or total display blackout.

Diagram Style Breakdown:

• Panel Layer → Displays image.
• T-CON Board → Processes image signals.
• Ribbon Cables → Connect T-CON to panel.
• Backlight → Illuminates the screen.

If any of these connections fail, the screen malfunctions.

Solutions:

• Screen replacement – If cracked or shattered.
• T-CON board replacement – If lines or partial image distortion occurs.
• Ribbon cable reseating – If loose or oxidized.
• Pixel refresh or compensation cycles – For OLED TVs with dead pixels.

At Refitec, we have replacement panels and T-CON boards in stock to ensure quick turnaround.

Maintenance Tip:

Avoid touching the TV screen with hard objects. Use a microfiber cloth for cleaning and install a surge protector to prevent voltage spikes damaging the panel.

2. TV Power Problems – Won’t Turn On or Keeps Restarting

Common Issues:

• TV won’t power on.
• TV keeps restarting in loops.
• Red standby light blinking but no display.

Technical Explanation:

Power issues often originate from the Power Supply Board (PSB), which converts AC electricity into regulated DC voltages (e.g., 3.3V, 5V, 12V, 24V). Over time, capacitors bulge or leak, MOSFETs fail, or fuses blow, disrupting voltage delivery to the motherboard.

Diagram Style Breakdown:

• AC Input → Fuse → Rectifier → Filter Capacitors → Regulators → Output to Motherboard.

If any stage fails, the TV cannot boot properly.

Solutions:

• Replace blown capacitors with high-quality low-ESR capacitors.
• Repair or replace damaged MOSFETs.
• Swap faulty power supply boards (we stock genuine replacements).
• Fix firmware corruption if power cycling is caused by software crashes.

Maintenance Tip:

Always plug your TV into a voltage regulator or UPS to prevent surges. Avoid switching it on and off rapidly.

3. TV Sound Problems – No Audio or Distorted Sound

Common Issues:

• TV powers on but has no sound.
• Distorted, crackling, or buzzing sound.
• One speaker working, the other silent.
• HDMI ARC or optical sound not working.

Technical Explanation:

TV audio is managed by the audio IC (integrated circuit) on the mainboard, connected to internal speakers and external sound output ports. Failures occur due to:

• Blown audio IC chips.
• Damaged speaker coils.
• Software glitches affecting sound drivers.
• Faulty HDMI ARC/Optical ports.

Solutions:

• Replace damaged speakers.
• Re-solder or replace faulty audio IC chips.
• Update TV firmware to restore audio functions.
• Repair/replace damaged audio output ports.

At Refitec, we stock genuine replacement speakers, audio ICs, and HDMI ports for all major TV brands.

Maintenance Tip:

Connect your TV to a home theater or soundbar via optical/HDMI ARC to reduce wear on internal speakers.

4. TV Backlight Problems – Dim Screen or No Picture

Common Issues:

• TV turns on with sound but no picture.
• Screen appears too dim.
• Flashlight test shows faint images on the screen.

Technical Explanation:

LED TVs use an array of LED strips behind or on the edges of the screen. Over time, LEDs burn out, leading to uneven brightness or total blackout. The backlight inverter circuit may also fail, cutting off power to the LEDs.

Diagram Style Breakdown:

• Power Board → Backlight Inverter → LED Strips → Panel.

Solutions:

• Replace burnt LED strips.
• Replace faulty backlight inverter boards.
• Adjust backlight settings in the TV menu to prolong lifespan.

We carry genuine LED strips and inverter boards for fast repairs.

Maintenance Tip:

Keep brightness at 50–70% to extend backlight life. Avoid leaving static images on the screen for long periods.

5. HDMI & Input Port Issues

Common Issues:

• HDMI not detecting input.
• AV/USB ports not working.
• Loose HDMI connection.

Technical Explanation:

HDMI ports can physically wear out due to repeated plugging/unplugging. Internally, the HDMI controller IC may also fail, causing signal recognition errors.

Solutions:

• Re-solder loose HDMI ports.
• Replace broken ports with new ones.
• Replace HDMI controller IC if ports remain unresponsive.

6. Software & Smart TV Problems

Common Issues:

• TV stuck on logo (boot loop).
• Apps crashing or failing to load.
• Wi-Fi/Bluetooth not working.

Technical Explanation:

Smart TVs run on operating systems like Android TV, WebOS, Tizen, or VIDAA. Corrupt firmware, outdated apps, or faulty Wi-Fi modules cause functionality issues.

Solutions:

• Firmware reinstallation or upgrade.
• Factory reset to clear corrupted files.
• Replace faulty Wi-Fi modules if hardware related.
