The 10 most common TV problems in Lavington — explained, diagnosed, fixed

Below we treat each problem in its own section: cause, symptoms, simple checks you can do, how Refitec fixes it, estimated effort, parts to expect, and maintenance tips.

1. TV won’t power on (dead TV)

Symptoms: No LED, no sound, no fan, no response to remote or power button.
Common causes: Failed power supply board (SMPS), blown fuse, bad electrolytic capacitors, defective power switch, socket/power-strip issues, or motherboard failure.

Quick at-home checks:

• Try a different wall socket or known-good extension.
• Check the TV’s LED indicator for brief flashes.
• Smell for burnt electronics (stop using if you smell burning).

How Refitec diagnoses & repairs:

1. Visual & multimeter checks — We test AC at the plug, check standby voltages, and open the TV to visually inspect for bulging capacitors and burnt resistors.
2. Power board bench test — Power boards are tested outside the chassis with a dummy load where safe.
3. Replace & retest — If the SMPS is faulty we replace the board or repair caps/diodes as needed.

Parts used: Power board/SMPS, capacitors (electrolytic), fuses, resistors.
Maintenance tip: Use a surge-protected extension; avoid plugging into unstable power outlets.

2. TV turns on but then shuts off / reboots randomly

Symptoms: TV boots up but powers down after seconds/minutes, or restarts intermittently.
Common causes: Overheating, failing capacitors on power board, firmware watchdog resets, weak power supply, or faulty mainboard.

Technical breakdown: The TV’s power board supplies multiple DC rails to the mainboard and backlight drivers. If one rail drops under load, the mainboard’s safety circuit triggers a reset. Repeated thermal cycling can then appear as random reboots.

How we fix it:

• Stress-test the power board; replace weak capacitors.
• Clean cooling vents and remove dust.
• Update firmware if it’s a smart TV with known stability issues.

Diagram (simplified):

AC Power -> SMPS (power board) -> +12V, +5V, +3.3V rails -> Mainboard -> Backlight driver
                 ↘ Weak cap or overheat -> Voltage drop -> Reset

Maintenance tip: Keep vents clear; perform an annual dust-clean.

3. No picture but sound is fine

Symptoms: Sound plays but screen is black, sometimes with faint backlight glow.
Common causes: Failed backlight inverter (older CCFL sets) or LED driver/backlight LED strips (modern LCD/LED sets), faulty T-Con board (timing control), or HDMI/AV input detection problems.

What we check:

• Shine a torch at an angle to the screen while TV is on — if you see a faint image, backlight is off but LCD is working (torch test).
• Inspect T-Con board voltages and LVDS cable connections between mainboard and T-Con.

Refitec fix path:

• For faint image + torch test: Replace LED driver or LED strips/backlight. We first test the backlight strips with a lamp/LED tester.
• For no image at all: Test/replace T-Con board or HDMI/Video processor on mainboard.

Parts: LED strips, LED driver board, T-Con board, LVDS cable.
SEO phrase to attract customers: “LED backlight replacement Lavington” — customers use this when they see picture but no light.

4. Lines on screen, distorted or flickering picture

Symptoms: Horizontal/vertical lines, color bands, flicker, or distorted patches.
Common causes: Faulty T-Con board, damaged flex cables, failing panel driver ICs, or heat-related solder joint cracks on the mainboard.

Technical note: The T-Con drives sub-regions of the panel; a failing T-Con often produces vertical/horizontal lines or repeating patterns. Panel-level faults (row/column drivers) are expensive — sometimes replacement is more cost-effective than repair.

How Refitec approaches it:

• Swap T-Con with a known-good board where possible.
• Re-seat and reflow suspect solder joints on mainboard connectors.
• If panel (glass) itself is faulty, we advise on panel replacement cost vs replacement TV.

Maintenance tip: Avoid banging the screen; use proper wall mounts and avoid rapid temperature swings.

5. Broken or cracked screen (physical damage)

Symptoms: Shattered glass, black blotches, multi-colored smears, or dead zones.
Cause: Physical impact, pressure, or accidental drops.

Reality check & options: Modern flat-panel screens (LCD/LED/OLED) are delicate and panel replacement is often the most expensive component — sometimes exceeding the value of the TV. Refitec will:

• Assess whether the glass/glass-and-panel assembly can be sourced.
• Provide an honest cost comparison: panel replacement vs buying a replacement TV.
• If you choose repair, we source compatible panels (model-specific) and perform careful replacement and recalibration.

Parts: Specific panel assembly (model-specific), new bezel adhesives, backlight calibration if needed.
Maintenance tip: Use screen protectors where feasible and consider stable stands/wall mounts.

6. Backlight flicker, dimming, or partial lighting

Symptoms: Screen dims, flickers, or parts of screen are darker.
Common causes: Aging LED strips (loss of luminance), failing LED driver board, bad solder joints, or failing power supply rails.

Technical intervention: We measure LED string currents and voltage drop across LED strips. If LED strips are weak or failing, we replace the entire set (strips must match brightness and length specs). If driver board fails, we replace or repair the driver.

Diagram (LED strips):

LED Driver -> LED Strips (series strings) -> Connector -> Diffuser -> LCD panel

Note: Mixing LED strip models can produce uneven color/brightness — we always match part spec.

7. Sound issues (no sound, distorted audio, buzzing)

Symptoms: No audio, low volume despite settings, distorted sound, or intermittent audio cutouts.
Common causes: Blown speakers, faulty audio amplifier on mainboard, poor grounding, bad capacitors on audio circuit, or bad firmware/driver issues on smart TVs.

Fix approach:

• Test audio output (headphone jack / optical out).
• If external audio works, amp stage on board is faulty — we repair/replace amplifier circuits.
• Replace speakers if blown.

Maintenance tip: Avoid high-volume playback for long durations; it reduces speaker life.

8. HDMI/Smart TV input problems (no signal / apps crashing)

Symptoms: HDMI devices not detected, streaming apps crash, or Wi-Fi disconnects.
Common causes: Faulty HDMI ports, corrupt firmware, failing mainboard, or network issues.

How we help:

• Test with multiple HDMI devices and cables.
• Inspect HDMI board and replace if ports are damaged.
• Re-flash or update TV firmware, reset smart TV platform.
• For Wi-Fi issues, we test the Wi-Fi module and antenna connections.

SEO phrase: “Smart TV diagnostics Lavington” — for customers with streaming issues.

9. Ghosting, retention or image burn (OLED / plasma symptoms)

Symptoms: Persistent faint images after switching content, uneven brightness.
Causes: Pixel retention (temporary) or burn-in (permanent) on OLED/plasma panels.

What to do: For OLEDs, temporary retention sometimes improves with screen-shifting and varied content; permanent burn-in requires panel replacement. Refitec will run pixel refresh cycles where supported and advise replacement if severe.

Maintenance tip: Use dynamic content, avoid prolonged static logos, and use screensavers.

10. Remote or control problems

Symptoms: Remote not working, TV not responding to buttons.
Common causes: Dead batteries, IR receiver failure, or mainboard software hang.

Quick checks: Replace batteries, test remote with phone camera (IR LED shows on camera if working). If receiver is dead we inspect front board and replace IR sensor or perform a software reset.

Deeper technical breakdowns (for curious customers)

Inside a modern LED/LCD TV — component map

[AC IN] --> [Power Supply / SMPS] --> provides +12V, +5V, +3.3V rails
                  |
                  +--> [Mainboard / Motherboard] --> CPU, tuners, HDMI, network, audio amp
                  |
                  +--> [T-Con Board] --> LVDS -> Panel timing

                  |
                  +--> [Speakers / Amplifier]

Why each part matters:

• SMPS (power board): feeds stable DC voltages. A sagging rail creates all kinds of symptoms.
• Mainboard: brains — software, video processing, HDMI handling. Faults here mimic many issues.
• T-Con: timing & pixel driving — lines and distortion point here.
• LED driver & strips: light the panel — black screen with sound is classic backlight failure.

Typical diagnostic process Refitec uses (step-by-step)

1. Phone triage: Ask about symptoms, model number, when it started.
2. On-site quick checks: Confirm power, simple resets, test inputs.
3. Transport to workshop (if needed): Full bench testing with multimeters and oscilloscopes.
4. Parts sourcing & quotation: We source OEM or compatible high-quality parts and send a transparent quote.
5. Repair & quality check: Run extended burn-in and calibration.
6. Return & warranty: Deliver with warranty information.

Spare parts — availability & quality

Refitec maintains a stock of commonly needed parts for popular brands and models: power boards / SMPS, T-Con boards, LED strip sets, LED/backlight drivers, mainboards (model matched), speakers, capacitors, fuses, connectors, and LVDS cables. For rarer models we source from trusted suppliers or order original manufacturer parts when feasible. Because panels and very brand-specific boards can take longer or be costlier, we’ll always explain options (repair vs replace TV). We emphasize quality over cheapest components to avoid repeat failures.

Pricing transparency & what affects cost

Repair cost depends on: part price (panel or board), labour complexity (panel replacement is delicate), availability, and diagnostics time. Typical examples (indicative):

• Power board repair/parts: low–medium.
• Backlight LED strip replacement: medium (parts + labour).
• T-Con board replacement: low–medium.
• Panel replacement: high (often >50% of replacement-TV cost).

Always get a written quote. Refitec provides clear breakdowns: diagnostics fee (if any) + parts + labour + warranty terms.

On-site vs Workshop repair — which to choose?

• On-site: Good for simple fixes: firmware updates, remote re-pairing, loose cable reseating, and small board swaps. Convenient for busy customers.
• Workshop: Needed for power board bench testing, panel disassembly, soldering, LED strip replacements, and extended diagnostics.

Refitec offers both. For complex jobs we always recommend workshop repair for safety and better testing equipment.

Common do-it-yourself checks & safety warnings

You can safely do these:

• Try a different known-good power outlet.
• Swap HDMI cables and ports.
• Test remote batteries.
• Soft reset: unplug TV for 60 seconds, then plug back.

Do NOT do these at home (dangerous):

• Open TV chassis if you are not trained — large capacitors on the power board hold charge.
• Touch power supply components immediately after unplugging.
• Attempt soldering on the mainboard unless experienced.

Preventive maintenance (keeps the TV healthy)

• Keep TV vents and wall behind it clear for airflow.
• Dust the back of the TV every 6–12 months (power off and unplug first).
• Use surge protectors and avoid frequent power fluctuations.
• Avoid leaving static images on screen for long periods (streaming logos, gaming HUDs).
• Mount TV on secure brackets to prevent drops.

Model-specific & brand considerations

Different brands have common recurring faults (e.g., some models of Brand X suffer capacitor aging on the SMPS; Brand Y panels have specific LED strip layouts). When you call, tell us the brand, exact model number, and we’ll fast-track a diagnosis and tell you likely part availability.
