All common television problems (one by one) — diagnosis & how GossTech fixes them
Below we list every common TV fault you’ll encounter, describe how GossTech diagnoses it, and explain the typical repair steps we take. Use this as a quick reference for customers and SEO-rich content that demonstrates expertise.
1. TV won’t power on (no lights / dead)
Symptoms: No standby LED, no sound, no backlight.
Diagnosis steps: Multimeter checks on mains input, fuse, power board voltages, PSU capacitors, and standby circuit. Visual inspection for bulging/leaking capacitors or burn marks.
Repair process: Replace faulty fuses or blown mains components; replace faulty capacitors or power board modules; test standby/sleep circuits; perform burn-in test. If the power board is beyond economical repair, we replace with a compatible unit.
2. TV turns on but no picture (black screen) / backlight failure
Symptoms: Sound is present but screen is black or very dim. Remote and indicators work.
Diagnosis steps: Verify whether signal is arriving (input/decoder), check T-con board, LED strip/backlight inverter, and LVDS cable between mainboard and T-con. Use flashlight trick to see faint image if backlight is off.
Repair process: Replace faulty LED strips or backlight inverter, repair/replace T-con board, reconnect/replace LVDS cable, recalibrate backlight driver. For edge-lit and direct-lit LED TVs we use LED strip kits or repair controllers as necessary.
3. TV shows lines on screen (vertical/horizontal)
Symptoms: Thin or thick lines, flickering bands across display.
Diagnosis steps: Identify whether lines follow input signal (cable/decoder) or are internal (T-con, panel flex). Test with different inputs and a test pattern. Inspect T-con board and panel connectors.
Repair process: Repair/replace T-con board, replace panel flex cables, reseat connectors. If the LCD/OLED panel itself is failing, we provide repair vs replacement advice and quotes.
4. TV has distorted or no sound
Symptoms: No audio, low volume, humming, crackling, or distorted sound.
Diagnosis steps: Check internal amplifier board, speaker wiring, main board audio outputs, and software audio settings. Test with external speakers/USB media.
Repair process: Replace blown speakers or audio amplifier ICs, repair wiring/connectors, update firmware if audio bugs are software-related, or replace audio section boards.
5. TV shows “No Signal” or input problems
Symptoms: “No Signal” message, HDMI inputs not detecting devices, intermittent connection.
Diagnosis steps: Test multiple HDMI/AV inputs, replace cables, test source equipment (decoder, DVD, game console), inspect HDMI ports for bent pins or cold solder joints.
Repair process: Clean/repair or re-solder HDMI ports, replace connectors, repair mainboard HDMI circuits, advise on cable or decoder faults if sources are the issue.
6. Remote control not working or partial control
Symptoms: TV won’t respond to remote, or only some functions work.
Diagnosis steps: Test remote batteries, IR receiver on TV, pair remote for smart TVs, check software/firmware pairing, and test with smartphone IR apps where applicable.
Repair process: Replace IR receiver module, re-pair remote or replace remote, replace smart remote batteries, or update TV firmware to resolve pairing bugs.
7. TV overheating / shuts down after some time
Symptoms: TV works then suddenly powers off or restarts; rear case hot.
Diagnosis steps: Inspect ventilation, measure component temperatures, check power supply and mainboard for failing components causing heat.
Repair process: Clean air vents, replace failing capacitors or heat-generating ICs, improve thermal pads or heatsinks, advise relocation for better ventilation.
8. Smart TV apps crashing / slow interface / firmware issues
Symptoms: Apps freeze, Wi-Fi connectivity problems, slow menus, repeated rebooting after updates.
Diagnosis steps: Check firmware version, run factory reset, test Wi-Fi strength, inspect storage usage (some smart TVs allow app cache clearing).
Repair process: Firmware updates, factory reset with data backup advice, replace internal eMMC/flash module if corrupted (workshop repair), or recommend external streaming stick when repair is uneconomical.
9. Ghosting, double images or poor picture quality
Symptoms: Double images, echoing, ghost shadows, or poor color reproduction.
Diagnosis steps: Test with different sources and cables, check deinterlacing and picture processing on the mainboard.
Repair process: Repair/replace the main processing board (mainboard), calibrate picture settings, replace failing components that cause image processing artifacts.
10. Physical damage (cracked screen, water ingress)
Symptoms: Cracks, permanent black spots, or the TV fails after spills/rain.
Diagnosis steps: Visual assessment of panel damage, check if any internal boards survived.
Repair process: For small cracks or backlight damage we can sometimes repair connectors; for major cracked panels we provide honest quotes for panel replacement vs replacement TV (often replacement is more cost-effective). For water damage we perform full dry-out, clean corrosion, replace damaged boards where possible.
11. Power surges & lightning damage
Symptoms: TV dead after storm, fuse blown, smoke smell.
Diagnosis steps: Inspect for surge marks, test major boards, check for failed surge protectors or TV’s internal transient suppression.
Repair process: Replace damaged boards or components; advise installing external surge protection or UPS for critical setups.
Typical GossTech repair workflow (step-by-step)
- Customer contact & preliminary troubleshooting — Phone/WhatsApp triage (+254 723 613 664). We walk through basic checks (power, cables, other inputs).
- Onsite visit or collection — For simple repairs we attend onsite in Kangai and nearby localities. For complex board or panel repairs, we collect the TV or the customer brings it to our Nairobi workshop (pickup/drop options available).
- Full diagnostic & estimate — We perform a thorough diagnostic and present a transparent repair estimate (parts + labour). No surprise fees.
- Repair & parts sourcing — We source genuine or high-quality compatible parts; repair and replace boards, panels, LED strips, power supplies, etc.
- Testing & calibration — After repair we run extended tests, calibrate picture and audio, and ensure all functions work (smart apps, remote, tuners).
- Handover & warranty — We return the TV and provide a limited warranty on parts and labour (terms vary by repair type). We also give preventive maintenance tips.
Pricing / When to repair vs replace (guidelines)
| Situation | Typical recommendation |
|---|---|
| Faulty PSU or T-con in mid/large TV | Repair (parts generally cheaper than panel replacement) |
| Cracked panel (physical damage) | Often replace TV — panel replacement commonly costs nearly as much as a new TV |
| Smart TV firmware corruption | Repair/update — usually economical |
| Repeated major board failures or multiple component failures on older CRT/LCD | Evaluate replacement due to high parts & labour cost |
GossTech always provides a clear quote and recommendation after diagnosis so you can decide.
Preventive maintenance tips (keep your TV healthy longer)
- Keep the TV in a well-ventilated spot; don’t block vents.
- Avoid direct sunlight and excessive dust — dust with a microfiber cloth regularly.
- Use a surge protector or UPS where power is unstable.
- Turn off the TV when not in use instead of leaving it in standby for long periods.
- For smart TVs, install only trusted apps and update firmware when stable releases are available.
