Common TV Problems We Repair

Here are some of the most frequent issues we encounter in Spring Valley households:

• No power / TV won’t turn on
• Picture issues: black screen, flickering, lines, dead pixels
• Sound issues: no sound, distorted sound, speaker problems
• Image and color distortions: washed-out colours, color bleeding, discoloration
• Power surges and voltage issues
• Physical damage: cracked screen, broken ports (HDMI, USB)
• Backlight failure (on LED/LCD TVs)
• Faulty mainboard or T-con board malfunctions

We carry original and high-quality spare parts, from capacitors and power supply modules to backlight strips, T-con boards, mainboards, speakers, HDMI boards, etc. Let’s explore each of these problems in depth.

1. No Power / TV Won’t Turn On

Technical Breakdown

When a TV shows absolutely no sign of life — no standby light, no sound, no display — the issues are often within the power supply circuit or mainboard power section. Key components include:

• AC input section: where the mains 220V (or local voltage) enters
• Rectifier / bridge diodes: converting AC to DC
• Filter capacitors: smoothing the DC output
• Voltage regulators / switching power supply (SMPS): generating required voltages for logic board, T-con, LED backlight, etc.

A schematical “diagram-style” layout might be:

[AC Mains] → Fuse → EMI/Line Filter → Rectifier → Bulk / Smoothing Caps → SMPS Boost/converter stages → Voltage rails (e.g. +5V-12V-24V etc) → Mainboard / T-con / Backlight

Common failures:

• Blown fuse or input fuse
• Faulty bridge diodes
• Bulging / dried-out capacitors
• SMPS switching IC (controller) failure
• Overheating or thermal damage

Solution

• Diagnose with a multimeter: check if fuse is intact, check if bridge diodes are conducting, check if DC rails produce expected voltages.
• Replace faulty capacitors (electrolytic caps), especially bulged or leaking ones.
• Replace burnt or failed SMPS controller ICs and MOSFETs.
• If power supply board is irreparable, replace with a matching high-quality spare part.

We stock power supply boards, fuses, regulators of many TV brands (Samsung, LG, Sony, Phillips etc.).

Maintenance Tips

• Use a surge protector or voltage stabilizer on Valley Road, Garden Estate, etc., to avoid damage from voltage spikes.
• Keep vents clean; ensure the TV has proper airflow to prevent overheating of the power supply.
• Avoid leaving TVs in standby for long periods; occasionally power off to let capacitors discharge and reset.

2. Picture Issues: Black Screen, Flickering, Lines, Dead Pixels

Technical Breakdown

Picture problems span a variety of drops:

• Backlight failure (for LCD/LED TVs) — the display panel is intact but no illumination.
• T-con board issues — responsible for timing control between video input and panel. It drives the row/column lines in modern edge/backlit screens.
• Panel driver IC faults or gate/drain driver malfunctions — often produce lines, flickering, dead rows or columns.
• Cable/connectors problems: LVDS cable (from T-con to panel), loose connectors.

Simplified Signal Path:

Video input (HDMI / Composite / Tuner) → Mainboard DSP → T-con board → Panel driver ICs → LED backlights

Solution

• If backlight is out: test for illumination using a flashlight over the dark screen; if faint images are visible, backlight has failed. Replace LED strips or inverter (for CCFL backlights in older sets).
• Flickering or lines: test by reseating LVDS ribbon cables, inspect for damage. Replace T-con board if faulty.
• Dead pixels: repair may be possible via panel replacement or specific pixel-repair firmware/hardware; in many cases cost-versus-value means recommending a new panel or new TV.
• Replace panel driver ICs if localized faults, or the entire panel if multiple sections are failing.

We carry T-con boards, LED backlight strips, driver ICs for many TV brands.

Maintenance Tips

• Avoid handling the screen directly; static discharge can damage driver ICs.
• Keep humidity moderate; water vapor can cause corrosion in connectors.
• Avoid leaving static images for prolonged time (screen burn-in on plasma or OLED); shift screensavers, etc.

3. Sound Issues: No Sound, Distorted Sound, Speaker Problems

Technical Breakdown

Sound path involves:

• Mainboard or audio IC → Amplifier / audio output stage → Speakers

Problems may come from:

• Faulty audio IC or DAC (Digital-to-Analog Converter)
• Blown speakers – physical damage, voice coil failure
• Bad solder joints or broken wires leading to speaker units
• Issues in firmware/software muting or volume circuits

Solution

• Open speaker grilles, inspect for physical damage, tear, or displacement. Test speaker resistance (ohms). Replace speakers with correct impedance spare parts.
• Check audio output voltages from mainboard; replace audio amplifier section or relevant IC if signal absent.
• Debug firmware or settings – ensure mute isn’t engaged; check external audio settings.

We stock replacement speakers, audio-amplifier boards, original audio ICs for many sets.

Maintenance Tips

• Avoid pushing sound at maximum volumes for long periods – protects the speaker voice coil.
• Keep dust out of speaker vents; gently vacuum to remove debris.
• Avoid moisture – avoid placing TV where cooking steam or moisture accumulate.

4. Image & Color Distortions: Washed-Out Colours, Colour Bleeding, Discoloration

Technical Breakdown

Color issues often originate from:

• Incorrect display calibration or drift in color voltage levels (red, green, blue channels)
• Failing capacitors or resistors in color gating circuits
• Backlight degradation – LED aging causes spectrum changes, so whites appear bluish or yellowish.
• Aging optical films/diffuser sheets inside panel; polarizing filters degrade.
• In plasma or OLED: phosphor aging or differential aging (burn-in).

Solution

• Use calibration tools (colorimeter) to read white balance and RGB curves; adjust via internal servicing menus or via external tools.
• Replace failed components in color drive circuits.
• Replace backlight LED strips in complete matched sets to restore uniform light spectrum.
• Clean or replace diffuser layers and optical films if accessible.
• For plasma/OLED suffering burn-in, some models allow pixel refresh or panel replacement.

Again, spare parts for colour driver circuits, backlight LEDs, filters are available.

Maintenance Tips

• Avoid exposing the TV to direct sunlight, which accelerates aging of filters and backlights.
• Use proper display mode — “movie”, “standard” rather than “vivid” — to reduce color oversaturation and stress on circuits.
• Periodic calibration helps; don’t leave high brightness or contrast settings unless needed.

5. Power Surges & Voltage Issues

Technical Breakdown

Electrical supply in Nairobi – including Spring Valley’s roads (Valley Road, Spring Valley Road, Forest Road, CMS Road) – can be unstable. Surges or voltage spikes (e.g. from lightning, grid switching) cause:

• Overvoltage stress on AC input components
• Spikes passing through rectifiers damaging downstream circuits
• Surge‐induced burnouts of SMPS MOSFETs, output caps, controller ICs

Also undervoltage (brown-outs) can stress SMPS, causing under-voltage dropouts.

Solution

• Use quality voltage protectors or stabilizers at the input to TV.
• Replace any voltage protection components (MOVs / surge suppressors) inside the power board if damaged.
• Replace capacitors and damaged ICs resulting from surge damage.

We have stock of voltage protection parts, MOVs, surge suppressors, high-quality SMPS modules.

Maintenance Tips

• Always unplug TV during major storms or extended power outages.
• Use surge suppressor; ensure wiring in homes is properly grounded.
• Regularly inspect power board for signs of burn or scorch.

6. Physical Damage: Cracked Screen, Broken Ports (HDMI, USB)

Technical Breakdown

Physical damage can affect:

• The display panel itself (glass breakage). Replacing a panel is often expensive.
• Ports: HDMI, USB, AV – connectors may be damaged mechanically or electrically.
• Internal cables: flex cables, ribbon cables may be pinched or torn.

Solution

• For cracked panel: replace with original manufacturer panel or a high-quality compatible one. We stock several panel types for major brands.
• For ports: replace ports/connectors or entire board sections (HDMI board, USB board). Soldering tiny pins, using correct shielding.
• Ensure internal cable alignment, replacement of ribbon cables where needed.

Maintenance Tips

• Handle remote connections carefully; avoid forcing cables into ports.
• Use surge-protected, pull out TV plugs gently.
• Keep TV in an area with low traffic if possible to avoid accidental knocks.

7. Backlight Failure (LED/LCD TVs)

Technical Breakdown

Backlight is what lights up your LCD panel. Without it, even though image is being generated, screen is dark. Two main varieties:

• LED edge or direct backlight strips
• Older LCD TVs may have CCFL (cold cathode fluorescent lamps) with inverter circuits

Failures might be:

• LED strip burnout
• LED driver circuit failure
• Inverter failure (for CCFL)
• Degraded LED brightness over time

Solution

• Test with flashlight: if you see faint image, backlight is out.
• Replace LED strips in matched sets (so color temperature remains even).
• Replace the driver circuit or inverter if that is the failing component.
• For CCFL, replace fluorescent tubes and the high-voltage inverter.

We carry LED strip kits, inverter boards, driver circuits.

Maintenance Tips

• Reduce brightness to moderate levels; using full brightness accelerates LED aging.
• Avoid thermal stress – ensure ventilation.
• Use timer or auto-off standby to limit daily usage.

8. Faulty Mainboard or T-con Board Malfunctions

Technical Breakdown

The mainboard (sometimes called the motherboard or logic board) is where your TV’s user interface, input ports (HDMI, USB), video decoder, audio decoding, and processing live. Failures may cause:

• No input detection
• No video signal
• Booting issues (TV stuck on logo)
• Firmware corruption

The T-con (Timer Control) board is intermediary between mainboard and panel; it decodes timing for row/column addressing on the panel.

Issues may include:

• Corrupted firmware
• Failed chips (e.g. EEPROM, flash memory)
• Voltage supply to board failing
• Thermal stress leading to solder joint cracks

Solution

• Perform firmware updates where supported. Reflashing or re-writing corrupted firmware/Eeprom.
• Replace mainboard if essential components are damaged.
• Replace T-con board if image timing issues, flickering, missing “half-screen” portions.
• Resoldering joints for heat-affected areas; ensure proper heat sink where needed.

We have spare mainboards and T-con boards for many major brands.

Maintenance Tips

• Keep software/firmware up to date. Install manufacturer updates to fix bugs.
• Ensure TV unit is mounted in ventilated spaces; excessive heat causes solder fatigue.
• Avoid constant power cycling; sudden on-off cycles can stress board components.
