All common television problems — one-by-one, with diagnosis & repair process
Below we list every common television fault we encounter, explain the usual causes, and describe how GossTech diagnoses and fixes each issue. This section is deliberately detailed so you know what to expect.
1. Television won’t turn on (no power)
Symptoms: No lights, no boot sound, dead display.
Common causes: Faulty power supply board, blown fuse, damaged power socket, bad standby capacitor, internal short.
How GossTech diagnoses:
- Visual inspection of power cord and plug.
- Test wall outlet with a known-good device.
- Open TV (in-shop or onsite where safe) and test mains fuse, standby transformer, capacitors and voltage rails with meter.
Repair: Replace faulty fuse or power board, re-solder or replace bulging/leaky capacitors, repair burnt traces, or replace the entire power supply module. If the fault is external (socket or surge damage) we advise on electrical checks.
2. TV turns on but has a black/blank screen (no picture)
Symptoms: LED power light on, sound present (sometimes), screen remains black.
Common causes: Backlight failure (LED strips or CCFL tubes), T-con board issues, mainboard failure, loose LVDS ribbon cable, panel failure.
How GossTech diagnoses:
- Sound-check to see if audio is working (this narrows down to display subsystem).
- Flashlight test to check for faint image (indicates backlight failure).
- Measure backlight voltage and check inverter or LED driver board.
- Inspect T-con board and LVDS cable connections.
Repair: Replace faulty backlight LED strips or inverter, repair/replace T-con board, re-seat or replace LVDS cable, or replace the panel only if necessary. GossTech always tests parts on a bench before full reassembly.
3. Lines across the display (horizontal or vertical)
Symptoms: One or more lines of pixels remain lit or dark across screen.
Common causes: Damaged T-con board, faulty ribbon/tape connectors, panel permeable issues, mainboard video output fault.
How GossTech diagnoses:
- Inspect T-con and ribbon connectors for physical damage or corrosion.
- Swap T-con with a known-good unit (where available) to isolate fault.
- Test video signal at mainboard outputs.
Repair: Clean and re-seat LVDS ribbons, replace T-con board or cables, or replace the panel when necessary. We attempt component-level repair first to keep costs down.
4. Colour problems (strange tint, faded colours, or one colour missing)
Symptoms: Image colour shifted (green/pink/blue tint), missing red/green/blue channel.
Common causes: T-con failure, bad display driver ICs, faulty panel sub-circuits, firmware issues.
How GossTech diagnoses:
- Use built-in service menus to run colour tests.
- Swap inputs to rule out external source.
- Test T-con and mainboard signal outputs for color channels.
Repair: Replace or repair the T-con, reprogram or update firmware if applicable, or replace failing display driver ICs. We ensure colour calibration after repair.
5. Sound works but no picture (audio-only)
Symptoms: Audio plays; screen stays black or shows ‘no signal’ message.
Common causes: Backlight/inverter failure, T-con, or panel fault.
How GossTech diagnoses:
- Confirm audio presence to isolate problem to display.
- Check backlight power and T-con signals.
Repair: Replace backlight components, T-con board, or panel depending on fault.
6. TV shows ‘no signal’ or loses signal intermittently
Symptoms: ‘No signal’ message despite connected source; intermittent picture.
Common causes: Faulty HDMI/AV input ports, damaged source cable, firmware/EDID handshake problems, failing mainboard.
How GossTech diagnoses:
- Test with alternate HDMI/AV cables and devices.
- Inspect HDMI port for bent pins or physical damage.
- Update firmware and reset EDID where supported.
Repair: Replace or repair HDMI/AV ports, update firmware, replace mainboard if necessary.
7. TV keeps rebooting / power-cycling
Symptoms: TV starts, shows logo, then turns off and restarts repeatedly.
Common causes: Faulty power supply, shorted capacitors, bad firmware, failing mainboard.
How GossTech diagnoses:
- Monitor voltage rails under load.
- Inspect for swollen capacitors and burn marks.
- Check logs or boot sequences where service menus allow.
Repair: Replace power supply components or board, flash firmware, or replace mainboard.
8. Remote control not working or intermittent response
Symptoms: TV won’t respond to remote but responds to onboard buttons.
Common causes: Dead or weak batteries, faulty IR receiver, sticking remote buttons, line-of-sight/IR obstruction, or RF module failure (for smart remotes).
How GossTech diagnoses:
- Verify remote function with camera (IR LED should blink) or spare remote.
- Test TV’s IR receiver and onboard buttons.
Repair: Replace remote, fix or replace IR receiver module, clean button contacts, or re-pair RF remotes.
9. Smart TV apps not working or sluggish UI
Symptoms: Apps crash, slow loading, buffering.
Common causes: Firmware/software issues, insufficient internal storage, failing Wi-Fi module, or app updates.
How GossTech diagnoses:
- Check firmware version and available storage.
- Monitor Wi-Fi signal strength; test with wired connection where possible.
- Factory reset and test apps.
Repair: Update or re-flash firmware, repair/replace Wi-Fi module, clear storage or replace internal storage where feasible. We always backup settings where possible.
10. Burn-in or permanent image retention (mostly OLED)
Symptoms: Ghost images persist after content change.
Common causes: Prolonged display of static images, uneven pixel wear.
How GossTech diagnoses:
- Run pixel and uniformity tests, compare with age/usage history.
Repair / mitigation: - For mild retention, use pixel-refresh cycles and specialised software tests.
- For severe burn-in, panel replacement is the only guaranteed fix. We advise on prevention and usage practices.
11. Excessive heat from TV
Symptoms: TV hot to touch, sudden shutdowns, shortened lifespan.
Common causes: Blocked ventilation, failing power board or backlight, internal dust build-up.
How GossTech diagnoses:
- Inspect vents and internal dust levels, test power components under load.
Repair: Clean internal dust, repair or replace overheating components, recommend better ventilation or mounting solutions.
12. Physical damage (cracked screen, water ingress)
Symptoms: Visible cracks, water marks, vertical/horizontal lines, or no display.
Common causes: Accidental damage, drops, liquid exposure.
How GossTech diagnoses:
- Visual inspection to determine extent (panel vs internal boards affected).
Repair: Screen/panel replacement where parts available. For water ingress we perform full cleaning, dry and corrosion treatment, then test. We provide cost-effective advice where full replacement is more sensible.
13. LED backlight flickering or dimming
Symptoms: Flicker, uneven brightness, dark patches.
Common causes: Failing LED strips, driver board problems, loose connectors.
How GossTech diagnoses:
- Test LED driver outputs and measure current, inspect LED strips for shorts.
Repair: Replace LED strips or driver board and re-calibrate brightness.
14. Firmware upgrade failures or bricked TV
Symptoms: TV won’t boot after firmware update.
Common causes: Interrupted update, corrupt firmware file, storage failure.
How GossTech diagnoses:
- Attempt re-flash via USB or service port, check board-level access.
Repair: Re-flash firmware, replace corrupted storage chip, or replace mainboard if irrecoverable.
Diagnostic workflow used by GossTech (step-by-step)
- Initial intake & remote troubleshooting: Customer provides symptoms, model and serial. We attempt remote fixes (power cycle, factory reset) when possible.
- Onsite check (Kagumo): For simple faults we visit the home, perform safety checks, and either fix onsite or collect the set for workshop repair.
- In-shop diagnosis: Full bench testing: power supply, T-con, mainboard, panel tests, firmware checks. We provide a written diagnosis and estimate.
- Customer approval: No work begins without your approval of cost and parts.
- Repair & testing: We perform component-level repair, replace modules, or fit new panels followed by a 24–72 hour burn-in/test period.
- Quality assurance & handover: Final cleaning, accessories test (remotes, tuners), payment, and warranty issuance.

Prevention & maintenance tips for TV longevity
- Avoid static images: Turn off or use screen savers for news tickers or static displays.
- Proper ventilation: Don’t wall-mount without ensuring clearance for heat dissipation.
- Stable power: Use surge protectors or voltage stabilizers to prevent power-surge damage.
- Clean vents periodically: Dust build-up increases heat and shortens components’ lives.
- Service regularly: For heavy-use displays, schedule annual inspections.
