Why Refitec? — an honest, local promise

Refitec is positioned as a neighbourhood-friendly technician team: fast diagnostics, transparent quotes, original & quality aftermarket spare parts, and careful in-home or workshop repair options. We focus on preserving good screens where possible, replacing only when necessary, and explaining the technical root cause in plain English. Our job is to save you money without cutting corners.

SECTION 1 — THE MOST COMMON TV PROBLEMS (and what they really mean)

Below, each problem gets its own paragraph with causes, technical breakdown, repair approach, spare-parts note and maintenance tips.

1. Blank / black screen (power on but no picture)

What you see: TV powers on (power LED lights, sound or menus visible) but no picture — a black screen.
Common causes (technical): failed backlight (LED strip or CCFL in older sets), inverter board failure (in CCFL/backlight-driven sets), faulty T-Con (timing control) board, defective display panel, or power supply rails that supply voltage to the backlight.
How Refitec diagnoses: start with a strong flashlight test (shine close to panel to check for faint image) — faint image means backlight issue; if there’s no faint image, suspect T-Con or panel. Measure voltages on the LED driver/inverter and power rails; test T-Con LVDS signals from mainboard.
Repair steps (deep technical):

• Step 1: Open back cover, inspect main & power boards for swollen capacitors, burnt components, and disconnected cables.
• Step 2: Test LED strings for continuity and current draw. Replace LED driver/inverter if dead. For LED TVs, replace the LED strips or driver board; for older CCFL sets replace the inverter board and CCFL tubes.
• Step 3: If LED driver OK but no image, check T-Con board and LVDS cable — replace T-Con or flex cable if bad.
• Step 4: Panel replacement is a last resort and is usually cost-prohibitive, so Refitec recommends it only when panel faults are confirmed and customer approves.
  Spare parts: LED strips, LED driver boards, inverter boards, T-Con boards, LVDS cables, and (rarely) full panels available. We stock common LED strips and driver boards and can source OEM parts if required.
  Maintenance tip: Avoid leaving the TV in hot, humid rooms; dust build-up on vents causes overheating and shortens power/inverter component life.

2. Dim or uneven backlight / patchy brightness

What you see: Picture shows dark bands, corners dimmer than center, or TV looks faint even at max brightness.
Causes: failing LED strips (some diodes out), poor solder joints on LED strings, failing LED driver (uneven current), or thermal degradation of LED modules. In edge-lit TVs, diffusion sheets and light guides can degrade.
Technical fix: Replace only the faulty LED strips or reflow cold solder joints on LED connectors; recalibrate LED driver current. For edge-lit models, inspect and replace diffusion layers if necessary (rare).
Spare parts: LED strips in matched lengths and densities, drivers specific to the model. Refitec keeps a stock of the most common strip sizes used across Samsung, LG, Sony, Hisense and major brands.
Maintenance tip: Run screen savers occasionally and avoid static high-contrast images for prolonged periods (burn-in risk on some panels).

3. Lines across the screen (vertical/horizontal)

What you see: One or multiple thin lines, moving or fixed, vertically or horizontally.
Causes: Loose or damaged LVDS ribbon cable between the mainboard and T-Con; failing T-Con board; damaged panel drivers; or internal solder cracks on the display PCB. Thermal cycling often causes tiny solder joint failures.
Diagnostic approach: Re-seat or swap LVDS cable; test with spare T-Con board; inspect for burn marks on the panel flex connectors.
Repair approach: Replace or reflow the T-Con board or LVDS cable; panel driver faults may require panel replacement.
Maintenance tip: Avoid physically stressing the screen (gentle handling during cleaning) — flexing can damage faint internal connectors over time.

4. TV won’t turn on / no power

What you see: TV shows no LEDs, dead.
Causes: Entirely dead power supply, blown fuse, bad mains input (socket or power cord), or internal short from surge or lightning. Swollen electrolytic capacitors on power board are a classic culprit.
Technical repair: Check mains, swap power cable, open and inspect PSU for bulging caps/resistors. Replace faulty capacitors, diodes, or whole PSU board depending on damage. Test standby rail and 12V/24V outputs.
Spare parts: Power supply boards specific to model, mains transformers, fuses. Refitec keeps many PSU boards for common models and can source OEM replacements.
Maintenance tip: Use a good surge protector/UPS for expensive smart TVs — mains spikes cause many PSU failures.

5. Intermittent picture, screen flicker or reboots

What you see: Picture flickers, occasionally goes blank, or TV reboots randomly.
Causes: Overheating, failing capacitors in power board, flaky mainboard firmware/hardware, or HDMI/ARC/CEC handshake problems. In older sets, failing backlight drivers can trigger intermittent resets.
Repair method: Run firmware update; stress-test power rails; replace aging capacitors; check HDMI devices and cables (a bad HDMI input can freeze a TV). If overheating, clean dust and check thermal pads.
Maintenance tip: Keep ventilation clear and avoid stacking devices on top of the TV.

6. Sound issues (no audio, distorted audio, delayed audio)

What you hear: No sound despite picture, or crackling/distorted audio, or audio out of sync with picture.
Causes: Faulty audio amp on mainboard, blown speakers, bad firmware drivers (audio codec), or digital audio path issues (HDMI ARC/optical). Audio sync issues sometimes stem from processing load or firmware bugs.
Repair approach: Test with headphones and external audio output; bypass internal speakers; check audio amp and replace electrolytic caps; update firmware or replace mainboard if audio codec is failing. For ARC/optical faults, inspect HDMI board and connectors.
Spare parts: Speakers, audio amplifier ICs (often part of mainboard), capacitors, HDMI audio boards.

7. Smart TV problems — apps crash, Wi-Fi disconnects, sluggish UI

What you see: Apps crash, slow menus, remote commands lag, or Wi-Fi connection drops.
Causes: Outdated firmware, failing flash memory, weak Wi-Fi antenna/connection, heavy background processes, or aging processing hardware. Some apps get deprecated and stop working.
Repair & tune: Update firmware, clear app cache, factory reset when necessary. If flash memory is defective (corruption), mainboard replacement may be needed. For Wi-Fi issues, test with wired Ethernet; replace Wi-Fi module/antenna if needed.
Maintenance tip: Keep TV firmware up to date and avoid installing too many third-party apps that hog memory.

8. Remote control or sensors not responding

What you see: Remote refuses to operate the TV or some buttons don’t work.
Causes: Dead remote batteries, IR receiver module fault, Bluetooth pairing lost (smart remotes), or stuck buttons on remote.
Fix: Test with universal remote; replace batteries; re-pair Bluetooth remote; replace IR sensor module if internally damaged.

SECTION 2 — DEEP TECHNICAL BREAKDOWNS (diagram-style text explanations)

Below are three “diagram-style” explanations in plain text to help you understand internal TV architecture and typical failure points. Imagine each block as a module — I’ll show the signal/power flow and the usual weak links.

Diagram A — Basic LED/LCD TV architecture (signal flow)

Source (Cable / HDMI / USB) → Main Board (SoC, Tuner, HDMI inputs) → T-Con (timing control) → Panel Drivers → LCD/LED Panel (pixels)
Power: Mains → Power Supply Unit (PSU) → 3.3V / 5V / 12V rails → Main board & LED Driver → LED strips

Weak links: PSU (caps), T-Con (timing & LVDS), LED strips/driver, mainboard HDMI ports.

Diagram B — Backlight system (edge-lit vs full-array)

Edge-lit: LED strips at edges → Light guide plate → Diffuser → LCD panel
Full-array: LED strips across entire panel → Local dimming zones controlled by LED driver

Weak links: Edge-lit relies on light guide (rare faults) and edge LED strips (most common). Full-array can have zone driver failures — visible as bands.

Diagram C — Smart TV software stack (simplified)

Bootloader → OS (Linux/Android/Tizen/WebOS) → Device drivers (Wi-Fi, Audio, Video) → App layer (Netflix, YouTube)
Weak links: Flash memory corruption (slow boots, app crashes), firmware incompatibilities (after updates), network drivers causing disconnects.

SECTION 3 — REPAIR WORKFLOW AT REFITEC (what to expect)

1. Initial triage (phone): Tell us symptoms, brand and model number. We’ll guide simple checks you can do (power cable, fuse).
2. Diagnostics: Either in-home basic check (if minor) or workshop drop-off for deeper multimeter/oscilloscope testing. Typical diagnostic fee is clearly quoted (waived if repair accepted).
3. Quote: Transparent price for parts & labour. We’ll explain OEM vs matched aftermarket parts and recommend warranties.
4. Repair & test: We test for at least 24 hours after repair to ensure stability. LED backlight replacements and power board repairs get thorough burn-in.
5. Return & support: We provide a short warranty on repairs and installed parts. If a replaced component fails under warranty, we fix it at no additional labour charge (terms apply).

SECTION 4 — SPARE PARTS: OEM vs QUALITY AFTERMARKET

• OEM parts (manufacturer originals) are preferred for panels and specific mainboards — they guarantee compatibility and color/profile matching, but cost more.
• Quality aftermarket (refurbished or matched replacement boards, LED strips) are a common cost-effective option. For LED strips, matched density and LED type matter — mixing creates color/brightness mismatch.
  Refitec carries a stock of common LED strips, driver boards, power supply assemblies and T-Con boards for leading brands (Samsung, LG, Sony, Hisense, TCL). We can source OEM parts on request — we’ll always flag when a panel replacement requires an OEM match.

SECTION 5 — COST GUIDES & WHEN TO REPLACE VS REPAIR

While specific prices vary by brand and model, these general rules help decide:

• Backlight replacement (LED strips + labour): often economical — many times cheaper than panel replacement.
• Power board repair (caps, diodes) vs replacement: if the PSU is simple capacitor failures, repair is cheap; if major ICs burnt, replacement may be better.
• Panel replacement: expensive and sometimes close to the cost of a new TV for older models. Replace the panel only if the customer values the TV (e.g., very large or high-end set) or if supply is affordable.
• Mainboard failure (smart functionality lost): replacing the mainboard usually restores full functions but always weigh against TV age.

Refitec will always give the repair vs replace recommendation with clear numbers.

SECTION 6 — MAINTENANCE TIPS (keep your TV alive longer)

• Use a surge protector or UPS for expensive sets.
• Keep vents clear and dust-free — use compressed air to clean vents twice a year.
• Avoid leaving static high-contrast images (news tickers, game HUDs) for long periods to reduce burn-in risk on some OLED/AMOLED panels.
• Update firmware when stable releases are available but avoid installing beta firmware.
• Use proper HDMI cables and avoid folding or sharply bending cable near connectors.
• If mounting on a wall, ensure constant stable temperatures and avoid direct sunlight — heat accelerates component degradation.

SECTION 7 — WARRANTY & AFTER-REPAIR SUPPORT

Refitec offers a limited parts & labour warranty on installed parts (length depends on part — e.g., LED strips 6–12 months, boards 3–6 months). We perform a 24–72 hour burn-in where the TV is stress-tested before returning to you.

SECTION 8 — COMMON BRAND-SPECIFIC NOTES (tips we apply during repair)

• Samsung & LG: Many models use proprietary LED strip lengths. We match spec or use OEM boards. Firmware updates sometimes resolve smart TV app issues.
• Sony: Panels are sometimes interchangeable across serials — we verify panel code before quoting.
• Hisense & TCL: Price-sensitive models often have common, affordable spare boards—repairs are usually economical.
• Older Plasma / CCFL sets: Inverter & CCFL replacement is possible but parts are aging — consider replacement if multiple failures exist.

SECTION 9 — SAFETY & DATA PRIVACY

When service requires accessing smart TV accounts or apps, Refitec recommends you either log out before handing in the TV or supervise re-login. We never retain passwords and will guide you on safe reset procedures.
