Common television problems (listed and explained)
Below we list the most frequent problems TVs develop. Each entry explains what the fault looks like, common causes, how GossTech diagnoses it, and typical repair actions.
1. No power / TV not turning on
Symptoms: No lights, no startup sound, TV completely dead.
Common causes: Faulty power supply board, blown fuse, damaged power cord, internal short, failed standby circuits.
GossTech diagnosis:
- Visual inspection of power cord and plug for damage.
- Measure outlet voltage and test with a known-good device.
- Open the back cover (workshop or on-site) and inspect the power supply board for blown components, bulging capacitors, scorch marks, or blown fuses.
- Use a multimeter to check fuses, voltage rails and standby voltages.
Typical repairs: Replace blown board fuse, replace damaged capacitors or diodes, repair traces, or replace the power supply board. In cases of irreparable damage we recommend board replacement with an OEM or compatible part.
2. TV turns on but displays a black screen (sound present)
Symptoms: TV powers up, you can hear sound or see backlight indicators but screen is black.
Common causes: Backlight failure (LED strips/inverter), T-Con board failure, faulty panel, loose LVDS cable.
GossTech diagnosis:
- Check whether the on-screen display (OSD) appears — if not, suspect the T-Con or main board.
- Shine a flashlight close to the screen to check if faint image is present (indicates backlight failure).
- Inspect backlight inverter circuits or LED driver boards.
- Test T-Con signals and LVDS connectors.
Typical repairs: Replace LED strips or inverter boards, replace or re-solder T-Con board, re-seat LVDS cables, or replace the panel if required (panel replacements are quoted separately and usually more costly).
3. TV has sound but no picture / flickering image
Symptoms: Image appears intermittently or flickers; colors unstable.
Common causes: Loose connections, failing T-Con, damaged ribbon cables, failing capacitors on main board or T-Con.
GossTech diagnosis:
- Re-seat and inspect all video ribbon cables and connectors.
- Swap T-Con or test with diagnostic patterns in the workshop.
- Inspect mainboard capacitors for signs of damage.
Typical repairs: Clean/re-seat connectors, replace T-Con board, replace damaged cables, repair or replace mainboard components.
4. Vertical or horizontal lines on screen
Symptoms: Persistent single or multiple lines running vertically or horizontally across the picture.
Common causes: Damaged LCD/LED panel (column/row drivers), faulty T-Con, loose ribbon connections.
GossTech diagnosis:
- Determine whether lines persist through different inputs (TV tuner, HDMI, USB).
- Open and inspect T-Con and panel connector; test T-Con replacement.
Typical repairs: Replace T-Con or panel connectors; if lines are due to panel driver damage the panel may need replacement.
5. Color issues (washed out, green tint, wrong colors)
Symptoms: Colors are inaccurate — image looks faded, overly green, or skin tones are off.
Common causes: Bad color processing on the main board, failed capacitors, incorrect picture settings, or firmware issues.
GossTech diagnosis:
- Reset picture settings to factory defaults.
- Test across multiple inputs to rule out source issues.
- Check mainboard video processing circuits.
Typical repairs: Repair or replace mainboard components, update firmware, or recalibrate picture settings.
6. TV restarts randomly / standby loop
Symptoms: TV turns on then off repeatedly or fails to remain powered.
Common causes: Faulty power supply volages, overheating, failing capacitors, or firmware bugs.
GossTech diagnosis:
- Monitor voltages during power-up to identify unstable rails.
- Inspect for overheating parts and test cooling elements.
- Check for firmware errors and apply updates where available.
Typical repairs: Replace failing capacitors or power supply components, clean vents and cooling areas, update firmware.
7. Remote control not working / TV does not respond to remote
Symptoms: TV won’t respond to remote commands; sometimes responds to power but not other commands.
Common causes: Dead batteries, IR sensor fault, or remote hardware failure.
GossTech diagnosis:
- Test remote with fresh batteries and confirm IR signal output with camera (phone camera shows IR LED blink).
- Test TV with front-panel buttons and a universal remote.
- Inspect IR sensor circuit on mainboard.
Typical repairs: Replace remote, replace/repair IR receiver or its connection to mainboard.
8. HDMI/AV ports not working / No input signal
Symptoms: “No Signal” or device not detected on HDMI/AV inputs.
Common causes: Faulty HDMI port, damaged cable, corrupted EDID handshake, failing mainboard.
GossTech diagnosis:
- Test multiple HDMI cables and input sources.
- Inspect HDMI port for physical damage.
- Use diagnostics to read EDID and confirm handshake.
Typical repairs: Repair/replace HDMI port, replace mainboard, or reflow solder joints on damaged connectors.
9. Ghosting, image lag or motion artifacts
Symptoms: Moving objects leave trails, motion looks smeared.
Common causes: Image processing issues, poor response time in panel, incorrect picture mode.
GossTech diagnosis:
- Test different picture modes and enable motion processing features.
- Run input lag and refresh tests (workshop) and check video processor chips.
Typical repairs: Firmware tuning, mainboard replacement, or panel replacement if severe.
10. Lines, dead pixels or burn-in on OLED/Plasma screens
Symptoms: Permanent discoloration, stuck/dead pixels, or image retention.
Common causes: Physical panel defects, prolonged static images causing burn‑in (mainly for plasma/OLED), manufacturing faults.
GossTech diagnosis:
- Pixel tests and burn-in analysis.
- Inspect for physical damage and confirm age/warranty status.
Typical repairs: Pixel-level repairs are rarely cost-effective; options include panel replacement or, for minor image retention, guided pixel-refresh cycles and software fixes.
11. Sound distortion or no sound
Symptoms: No audio, crackling, or distorted sound.
Common causes: Faulty audio amplifier on the mainboard, blown speakers, software/firmware issues.
GossTech diagnosis:
- Test audio from multiple sources and output routes (internal speakers, optical out, HDMI ARC).
- Inspect speaker connections and test amplifier circuits.
Typical repairs: Replace speakers, repair audio amplifier circuits on the mainboard, or update firmware.
12. Smart TV apps crashing or Wi-Fi connectivity issues
Symptoms: Apps freeze, streaming fails, or TV cannot connect to the internet.
Common causes: Corrupt app data, outdated firmware, weak Wi-Fi, failing network module.
GossTech diagnosis:
- Run network diagnostics and test with Ethernet (if available).
- Reset apps and factory reset the smart TV platform.
- Inspect internal Wi‑Fi module for faults.
Typical repairs: Reinstall or reset apps, update firmware, replace Wi‑Fi module if hardware fault, or advise on improving home network.
How GossTech diagnoses televisions — step-by-step process
GossTech follows a transparent, stepwise approach so you know what’s happening at every stage.
- Initial contact & triage: You call or email (+254723613664 / info@gosstech.co.ke) and describe symptoms. We perform remote troubleshooting where possible.
- On-site visit or collection: If remote fixes don’t work, we schedule an on-site visit (for simpler fixes) or arrange secure pickup to our workshop for full diagnostics.
- Comprehensive diagnostics: At the workshop, technicians run power, signal and board-level tests, inspect physical connections and run software/firmware checks.
- Repair estimate: We produce a clear written estimate listing parts, labour, turnaround time and warranty on repairs.
- Approval & repair: Upon approval we carry out the repair using tested parts and OEM-equivalent spares where available.
- Quality testing: After repair we run extended tests (burn-in, signal tests, audio/video checks) to ensure the issue is resolved.
- Return & follow-up: We return the TV, demonstrate the fix, provide a written invoice, and offer a warranty period (terms provided in the estimate).
