Common TV problems — overview (each issue as its own section)
Below we break down the most common faults we see, explain technical causes, and give repair approaches — each in its own paragraph for clarity.
1) Blank screen / no display (TV powers on but screen is dark)
Symptom: TV appears on (standby LED on, sound may be present) but the screen stays black or very faint.
Common causes: Failed backlight (LED strips or CCFL in older sets), bad power rail to the backlight, T-con board failure, or issues with the display panel itself (delamination/cracked internal layers). For smart TVs, firmware bugs rarely cause total black screen but can cause boot loops.
Diagnosis steps: (1) Listen for audio; if audio present but screen dark — suspect backlight/T-con. (2) Use flashlight test: shine a torch at the screen — if you can make out faint image, the panel is working but backlight is dead. (3) Check standby/power rails and LED driver voltages with a multimeter.
Fix options: Replace LED backlight strips or LED driver board; repair/replace T-con board if timing signals absent; if panel glass is cracked or internal glass failed — panel replacement (expensive). For LED backlights we stock and fit compatible LED strip kits. For older CCFL sets we can replace ballasts and tubes.
Preventive notes: Run TVs at moderate brightness and avoid leaving on in hot, unventilated rooms; ensure stable mains voltage with surge protection.
2) Backlight flickering, intermittent brightness
Symptom: Screen flickers or brightness fluctuates; may worsen with temperature or after several hours.
Causes: Aging LED strips, failing LED driver ICs, poor solder joints in the power/driver boards, weak capacitors in power supply. Dimming circuits and PWM drivers can also fail.
Technical fix: Replace LED strips or LED driver modules; reflow or replace cold solder joints; replace bulging or leaking electrolytic capacitors on power boards. We test in-situ with a DC bench supply to isolate driver vs strips.
User tip: If flicker happens immediately after turning TV on and stabilizes later — suspect capacitor aging. If it flickers at random, suspect thermal or connection issues.
3) Cracked or damaged screen / physical breaks
Symptom: Visible crack, lines, color blocks, or dead zones on the panel.
Causes: Impact, pressure, transport damage, or internal stresses/heat over time.
Options & costs (practical guidance): Screen/panel replacement is usually the most expensive repair, often a significant fraction of a new TV’s price. Our technicians will assess model availability and cost of replacement panels (many modern panels are model-specific). When a replacement panel is available and cost-effective, we replace it and recalibrate. Otherwise we advise replacement of the TV. Refitec keeps an inventory of commonly needed panels and sources them quickly for popular models.
Important: Never attempt to press or bend a cracked panel — glass shards may cause further damage and are hazardous.
4) Strange lines, colour banding, image artefacts (T-con or panel issues)
Symptom: Horizontal/vertical lines, color stripes, or tearing in the picture.
Causes: Faulty T-con (timing controller) board, bad LVDS/eDP cable connectors, damaged ribbon cables, or a failing panel column/row drivers.
Repair approach: Swap/test T-con board (a common and affordable repair), check and re-seat LVDS flex cables and connectors, inspect for water damage on connectors. If the panel has dead column drivers, panel replacement may be required. We often can repair with T-con swaps or cable replacements.
Diagram-style explanation (text): Signal path: Mainboard (video decode) -> T-con (timing & row/column drivers) -> Panel matrix. When the T-con fails, timing pulses to rows/columns are wrong causing lines/banding.
5) TV does not power on / no lights
Symptom: No LED, no response to remote or power button.
Causes: Blown fuse, defective power supply board, bad standby circuit, or mains/surge damage.
Technical steps: Check mains with wall outlet tester, check internal fuses, inspect switch-mode power supply (SMPS) components: main capacitors, diodes, transformers, MOSFETs. Many failures caused by blown electrolytic capacitors.
Fixes: Replace capacitors, MOSFETs, or power supply modules. For irreparable boards we fit compatible replacement boards or replace the chassis power module. We carry common PSUs and spares.
6) Sound but no picture (separating audio/video faults)
Symptom: Audio works (volume changes, menus audible) but no image. Often a backlight/T-con/panel issue.
Diagnosis: If menus are audible, try remote + display pairing: press menu and listen for audio cues while doing the flashlight test. If faint image visible with torch — backlight dead. If no image even with torch, suspect T-con or panel.
Repair: Replace backlight or T-con as per diagnostics.
7) Broken ports (HDMI/USB/AV) and connectivity
Symptom: HDMI inputs not detected, ARC not working, loose connectors, pixelation on streaming apps.
Causes: Mechanical damage to ports, faulty input modul, HDMI handshake issues, firmware bugs.
Fixes: Replace port/module, reflow solder joints, update firmware, or replace the mainboard if the input controller is integrated. We keep commonly used HDMI/USB boards and cables for popular models.
8) Smart TV issues — apps not loading, Wi-Fi disconnects, OS freezes
Symptom: Apps crash, TV slow, firmware update failures, Wi-Fi keeps disconnecting.
Causes: Corrupted firmware, failing flash memory, weak Wi-Fi module, overloaded caches.
Fixes: Firmware re-flash, factory reset, module replacement (Wi-Fi/Bluetooth), clear caches, or board-level repair for memory. For streaming performance, we recommend Ethernet where possible or a strong 2.4/5GHz Wi-Fi signal. Refitec can back up settings, update OS, and restore apps.
9) Remote control not working or TV not responding to remote
Symptom: TV ignores remote; some buttons work intermittently.
Causes: Dead batteries, dirty IR receiver, remote IR LED failure, or pairing issues for RF/Bluetooth remotes.
Fixes: Replace batteries, test remote with phone camera (IR emits near-infrared that camera can show), clean IR sensor, or re-pair remote for Bluetooth remotes. We also supply compatible replacement remotes.
Technical deep-dive (board-level, with diagram-style text)
Here’s a short, clear text-diagram to help you visualize key TV internals we often work on:
Mainboard (CPU, HDMI inputs, network) ──> LVDS/eDP ribbon ──> T-CON board (timing & logic for rows/columns) ──> Panel matrix (RGB subpixels; LED backlight behind the panel)
Power supply (SMPS) ──> Supplies +5V/+12V/+24V rails to mainboard, T-con, and LED driver.
LED Driver ──> Steps up/down and supplies string current to LED strips (backlight).
Common fault flows:
- No power => SMPS or mains fuse fault.
- No backlight but image faintly visible => LED driver or LED strips.
- Lines/stripes => T-con or LVDS cable.
- Sound but no picture => backlight or T-con.
- Random reboots/freezing => mainboard (firmware, flash memory) or poor power regulation.
Spare parts & replacements — what we stock
Refitec keeps a selection of commonly required components: LED backlight strips (for many Samsung, LG, Sony models), T-con boards, power supply modules, replacement mainboards for popular smart TVs, HDMI/USB modules, speakers, remotes, and a library of replacement panels for some models. For rare parts we perform targeted sourcing and provide cost estimates before ordering. We always recommend genuine or OEM-equivalent parts for longevity; where unavailable we fit high-quality compatible alternatives and test extensively.
Pricing and repair time (typical)
- Diagnostic fee: small, often waived if repair accepted.
- Backlight replacement: typically 1–3 days (part availability dependent).
- T-con replacement or board-level repair: same-day to 2 days.
- Panel replacement: 3–7 days depending on model/panel availability and cost.
- Firmware/USB/remote repairs: same-day.
Exact pricing depends on TV model and component costs — we’ll provide an itemized quote and a warranty on work and parts.
Safety & data notes
- Smart TVs may store Wi-Fi credentials and app logins. When handing over a TV for repair, consider signing out of personal streaming services if you’re concerned about privacy. We can assist with factory reset after repair.
- For cracked screens, be careful moving the TV; use two people and protective wrapping.
Maintenance tips — keep your TV working longer
- Ventilation: Keep rear vents clear; avoid placing TV in enclosed cabinets without airflow.
- Surge protection: Use a good surge protector or voltage stabilizer; Nairobi’s power fluctuations can harm SMPS.
- Dust control: Dust build-up inside increases heat — vacuum vents gently monthly and consider professional cleaning yearly.
- Avoid brightness max: Running at 100% brightness reduces LED lifespan. Use adaptive or eco modes.
- Power off at night: Reduces hours of use and thermal cycling.
- Gentle transport: Always transport panel face-up, on soft padding; avoid pressure.
- Software updates: Install official firmware updates from the manufacturer to keep apps and security stable.
