Detailed Breakdowns & Technical Explanations

1) Samsung Screen Repair & Replacement

Symptoms:

• Vertical/horizontal lines, half‑screen, color wash, black patches, ink‑like splotches.
• Cracked outer glass, spider‑web cracks, or pressure marks from cleaning or accidental hits.
• Ghosting, image retention, or stuck pixels.

Likely Causes:

• Physical impact/pressure on the LCD/OLED panel.
• T‑Con to panel ribbon damage; COF (chip‑on‑film) bond fatigue.
• Liquid ingress during cleaning (household sprays seeping into bezel).

Our Solution Path:

1. Diagnostics:
   • Inspect panel for mechanical damage vs. driver faults.
   • Scope‑test T‑Con LVDS outputs; check VGH/VGL/VCOM rails.
   • Flex ribbon reseat; microscope‑check COF edges for creases.
2. Repair/Replace:
   • Minor ribbon faults → clean/reseat; reflow under controlled temp if applicable.
   • Irreparable panel cracks → Panel/Screen replacement with genuine or OEM‑grade panel matched by panel code, size, resolution, and backlight type.
3. Post‑Work:
   • Update EDID if required; run pixel‑refresh for OLED models; uniformity check (5%/50% gray).

Diagram‑Style Flow:

[Symptom: Lines/Crack] → [Inspect Bezel + COF] → [Test VGH/VGL/VCOM] →
{Ribbon OK? Yes → Reseat/Clean} | {No → Panel Replace}
→ [Uniformity + Pixel Test] → [Calibrate Picture]

Maintenance Tips:

• Never press on the screen while wiping; use microfiber + 70% IPA lightly.
• Avoid window light hotspots; thermal stress worsens COF bonds.
• Use a proper tilt/swivel wall mount to prevent torsion when adjusting.

Note: For cracked LCDs/OLEDs, replacement is the only durable solution. We’ll quote both panel price and installation upfront and advise if replacement vs. new set is more economical.

2) Backlight Replacement (LED/QLED/Mini‑LED)

Symptoms:

• TV powers on (sound present) but screen is black; image visible only with a phone torch.
• Uneven brightness, spotlighting, or milky look; image appears then fades.
• TV restarts when brightness spikes (HDR scenes).

Root Causes:

• Aging LED strips causing open circuits; phosphor decay (blue shift).
• Backlight driver/boost IC overcurrent protection triggering.
• Thermal cycling due to high Brightness/Backlight settings and dust buildup.

Our Process:

1. Confirm: With a test backlight and driver readings: BOOST ~90–140V, per model.
2. Disassemble: Remove panel layers (diffuser, prism, reflector) dust‑free.
3. Replace: Full‑set LED strip replacement (not just one bar) to preserve uniformity.
4. Recalibrate: Reduce Backlight, enable Eco Sensor/Adaptive to lower stress.
5. Thermal Check: Inspect LED heatsinks/reflectors; re‑tape light guides; clean fans if any.

Diagram‑Style Steps:

[No Picture but Sound] → [Torch Test OK] → [Measure Backlight Driver] →
[Open LED Detected] → [Replace All Strips] → [Rebuild Optical Stack] →
[Uniformity Test: 5%/100% white] → [Lower Backlight to 40–60%]

Maintenance Tips:

• Keep Backlight under 60% for SDR; let HDR handle peak control.
• Ensure adequate ventilation; don’t enclose TV tightly in cabinets.
• Use Power Saving modes to reduce LED stress without losing clarity.

We Stock: Samsung‑compatible edge‑lit and direct‑lit LED strip kits, adhesives, and driver modules for popular sizes (32″–85″).

3) Power Faults & “Dead” TVs

Symptoms: No standby light, or red light blinks; relay clicking; sudden shutdowns.

Common Causes:

• Power supply board failures: PFC stage, primary MOSFET/bridge, NTC inrush, bad optocouplers.
• Shorted LED strings overloading PSU; failed backlight boost.
• Firmware crash causing boot loops.

Refitec Approach:

• Insulation tests; ESR testing of primary caps; check 5V/12V/24V rails.
• Isolate loads (mainboard/backlight) to pinpoint which rail collapses.
• Replace faulty components/boards; update firmware; soak test for 2 hours.

Quick Safety Tip: Always use a surge protector. Nairobi’s micro‑outages can spike primary stages.

4) No Signal, HDMI/ARC/eARC & T‑Con/Video Path Issues

Symptoms: “No Signal”, intermittent 4K HDR handshake, ARC not returning audio, half‑screen.

Causes:

• Worn HDMI sockets, torn pads; ESD from hot‑plugging.
• T‑Con driver issues: VGH/VGL losses, shorted gamma IC, blown fuses.
• EDID/HDCP handshakes broken after updates.

Fixes:

• Replace HDMI ports; reinforce with board‑safe solder work.
• T‑Con repair/replacement; check panel fuse and LVDS cables.
• Update firmware; reset HDMI‑CEC; verify certified High‑Speed cables for 4K120.

User Tips:

• Power down both TV and source before swapping cables.
• Use short, certified HDMI 2.1 where needed.

5) Sound Problems

Symptoms: No audio, crackling, one channel silent, ARC dropouts.

Causes:

• Blown speaker coils from overdrive; loose speaker gaskets.
• ARC/eARC mis‑config; SPDIF muted; codec mismatch on set‑top boxes.

Solutions:

• Replace speaker modules; reseat/insulate; fix cabinet buzz.
• Reconfigure Digital Output (PCM/Bitstream), CEC‑ARC settings; update soundbar firmware.

Tip: Avoid maxing volume; enable Auto Volume to protect drivers.

6) Smart TV, Wi‑Fi & App Issues

Symptoms: Wi‑Fi won’t connect, apps freeze, YouTube/Netflix sign‑in loops, Bluetooth dropouts.

Causes:

• Faulty Wi‑Fi/BT module; antenna cable dislodged.
• Corrupt app cache; outdated firmware; DNS timeouts.

Fixes:

• Replace Wi‑Fi/BT module; reseat antenna; update firmware.
• Reset Smart Hub; set DNS 8.8.8.8/1.1.1.1; clear cache; reinstall apps.

Tip: If the TV is wall‑mounted, keep router within 1–2 rooms; avoid metal enclosures that shadow RF.

7) Board‑Level Repairs (Mainboard, PSU, T‑Con)

We perform component‑level work where economical:

• Replacing MOSFETs, regulators, backlight driver ICs.
• Reflow/reball BGA where warranted (SoC/RAM storage faults).
• Firmware flashing via ISP/JTAG for certain mainboards.

Quality Controls:

• ESD protection, thermal profiling, conformal coating where original.
• 2‑hour functional soak tests: SDR/HDR, HDMI, tuner, Wi‑Fi, and app streaming.

Maintenance & Longevity Tips for Samsung TVs

• Power: Use a surge protector; avoid cheap multi‑plugs.
• Ventilation: Leave at least 10–15 cm clearance around vents.
• Brightness: Keep Backlight under 60% for SDR; use Eco modes.
• Cleaning: Microfiber only; never spray directly on the screen—spray the cloth.
• Firmware: Update quarterly; enable Auto Update but disable if a critical app breaks and call us.
• Cable Management: Use certified HDMI; avoid sharp bends; label sources.
