All Television Problems — Diagnosis & How GossTech Fixes Them

Below is a problem-by-problem breakdown. For each issue we explain signs, likely causes, how GossTech diagnoses it, and typical repair steps. This section is designed to be search-friendly (useful for long-tail queries like “TV no power Nairobi” or “sound but no picture Westlands”).

Quick note on safety: modern TVs contain high-voltage components (power boards, capacitors) and delicate displays. Always allow certified technicians to open and repair TVs.

1. TV won’t power on (no lights)

Signs: No LED standby light, no sound, no picture.

Likely causes: Faulty power board, blown fuse, failed mains input (AC inlet), damaged power cable, internal short.

GossTech diagnosis:

  • Visual inspection of power cable and AC inlet.
  • Multimeter tests on incoming AC and internal fuse continuity.
  • Test power board voltages and check for bulging/leaking capacitors.
  • Swap in a known-good power board (if available) to confirm.

Typical repair: Replace faulty power board or blown fuse, repair/replace damaged AC inlet or cable. We replace capacitors and other failed components when economical. If the mainboard is damaged, we advise replacement cost vs replacement TV.

2. TV has standby light but won’t turn on / keeps rebooting

Signs: Standby LED present; pressing power either does nothing or the TV turns on briefly then goes back to standby.

Likely causes: Faulty power supply regulation, bad capacitors, failing mainboard, thermal protection triggering.

GossTech diagnosis:

  • Log errors from service menu (if available).
  • Measure power rails and test capacitors under load.
  • Check for overheating components.

Typical repair: Replace bad capacitors on power board, repair or replace the mainboard, clean internal cooling pathways. If a firmware issue is the cause, apply official firmware update where available.

3. No picture / black screen but sound present

Signs: TV produces sound but screen is black.

Likely causes: Backlight failure (LED/LCD), T-CON board failure, LCD panel issues, poor LVDS/eDP cable connection.

GossTech diagnosis:

  • Shine a flashlight at an angle to check for a faint image (indicates backlight failure).
  • Test T-CON board signals and measure backlight voltages.
  • Inspect LVDS cable and connectors for corrosion or loose contacts.

Typical repair: Replace backlight strips (for repairable LED sets), replace LED driver board, replace T-CON board, reconnect/replace LVDS cable. If the LCD panel itself is cracked or has internal defects, we provide replacement or panel-replacement cost options.

4. Dim screen / uneven brightness

Signs: Screen lights but dim or with brightness inconsistency across the panel.

Likely causes: Weak LED backlight strips, failing LED driver, worn capacitors in power/backlight circuits.

GossTech diagnosis: Measure backlight voltages and current, inspect LED strips for failures.

Typical repair: Replace faulty LED strips or LED driver; recalibrate backlight settings and test for power stability.

5. Lines on screen (horizontal or vertical)

Signs: Persistent lines across the display, flickering lines, colored bands.

Likely causes: Faulty T-CON board, damaged panel row/column driver, bad LVDS cable or connector.

GossTech diagnosis: Swap or test T-CON board; test connector pins; inspect for physical damage to the panel.

Typical repair: Replace T-CON, replace or reseat LVDS cable, or—if panel driver circuits are damaged—discuss panel replacement.

6. Strange colors / color imbalance

Signs: Colors appear incorrect, tint skewed (too green, too red), or color banding.

Likely causes: Bad color IC on mainboard, faulty scaler, corrupted firmware, or display aging.

GossTech diagnosis: Run service-mode color tests, check mainboard outputs, attempt firmware rollback/upgrade.

Typical repair: Replace mainboard or color-processing IC, apply firmware fixes, recalibrate color settings.

7. Sound but no video (or video but no sound)

Signs: One subsystem works while the other doesn’t.

Likely causes: Separate audio and video processing circuits; failures can affect only one.

GossTech diagnosis: Use service menus and signal tracing to isolate audio or video stages.

Typical repair: Replace or repair the faulty board (audio amp, speaker wiring, mainboard), replace broken speakers.

8. TV shows lines and flickers when moved or tapped

Signs: Intermittent bar/flicker when the set is moved.

Likely causes: Loose internal connection (LVDS cable, ribbon cable), cracked solder joints, failing connectors.

GossTech diagnosis: Reproduce the fault by moving/tapping while technician probes connectors. Inspect for cracked solder and reflow if safe.

Typical repair: Re-seat or replace flex cables/connectors, repair solder joints, secure components.

9. TV remote not working / IR sensor issues

Signs: Remote commands ignored, sometimes intermittent.

Likely causes: Dead remote batteries, faulty IR receiver module, sensor blockage, remote pairing issues (for smart remotes).

GossTech diagnosis: Test remote with IR tester, test sensor with smartphone camera, check pairing status.

Typical repair: Replace remote (or batteries), replace IR receiver or re-pair the remote. Provide universal remote solutions.

10. Smart TV apps crashing / Wi‑Fi not connecting

Signs: Apps freeze/close, slow operation, cannot connect to internet.

Likely causes: Outdated firmware, corrupted app cache, weak Wi‑Fi module or antenna, overloaded internal storage.

GossTech diagnosis: Run network diagnostics, inspect Wi‑Fi module, check firmware and free up storage.

Typical repair / service: Firmware updates, factory reset with data backup instructions, replace Wi‑Fi module or connect via ethernet, optimize app set and storage.

11. HDMI/AV ports not working

Signs: No signal from connected set-top box, consoles, or external devices on HDMI/AV inputs.

Likely causes: Broken HDMI port, failed input switch IC, damaged cables, handshake (HDCP) issues.

GossTech diagnosis: Test with known-good cables and devices, inspect HDMI port for bent pins, test input circuits.

Typical repair: Repair/replace HDMI port, repair board traces, replace input switch IC, or provide adapter solutions.

12. TV overheats / shuts down after a while

Signs: TV switches off after running for some time; may smell hot or show thermal errors.

Likely causes: Dust-clogged vents, failed power regulation components, failing power board.

GossTech diagnosis: Thermal inspection, check ventilation and measure component temperatures.

Typical repair: Clean internal dust, replace failed fans (if present), repair/replace power regulation components.

13. Panel cracks / physical damage

Signs: Visible cracks, dead pixels, irregular blotches.

Likely causes: Physical impact, pressure, or manufacturing defects.

GossTech diagnosis: Visual inspection and panel testing.

Typical repair: Panel replacement (expensive) or recommend new TV if replacement cost compares unfavorably with a new set. For commercial displays, offer bulk/panel sourcing options.

14. Ghosting or image retention

Signs: Faint retained images after the content changes (more common on OLED/Plasma historically).

Likely causes: Image retention, burn-in, or temporary charge accumulation on panel.

GossTech diagnosis: Run pixel-refresh cycles, test with moving images.

Typical repair / mitigation: Pixel refresh routines, lowering static UI elements, apply warranty options for severe burn-in when manufacturer policy covers it.

15. Wireless casting / Bluetooth pairing problems

Signs: Casting disconnects, Bluetooth devices fail to pair.

Likely causes: Firmware bugs, Wi‑Fi interference, weak internal modules.

GossTech diagnosis: Network scans for interference, firmware checks, hardware tests of wireless modules.

Typical repair: Firmware updates, replace Wi‑Fi/Bluetooth module, reposition router or suggest Wi‑Fi improvements.

How GossTech Diagnoses — Our Step-by-Step Process

  1. Preliminary phone support: Customer calls or writes with symptoms and model details. We advise basic checks (power, cables) to save time.
  2. On-site visit or drop-off: Technician performs a visual inspection and replicates the fault (on-site where possible).
  3. Electronic diagnostics: Using multimeter, oscilloscope, and service software, we check voltages, signal paths, and firmware status.
  4. Parts sourcing & cost estimate: We provide a clear estimate for parts and labor and advise repair vs replacement.
  5. Repair & quality testing: Repairs are performed in-shop or on-site; 24–72 hour stress testing follows.
  6. Warranty & follow-up: We offer warranty on labor and replaced parts (terms provided with estimate).
