Full List of Television Problems — One by One (With Diagnosis & Repair Approach)
Below is a comprehensive list of TV faults commonly presented to our technicians. Each fault includes: what it looks like (symptoms), how GossTech diagnoses it, and the typical repair or replacement steps.
1. TV won’t turn on at all
Symptoms: No power LED, no sound, blank screen.
Diagnosis: Check mains supply, power cable, fuse, power board voltage rails using multimeter. Inspect remote and front-panel power switch. Check for blown electrolytic capacitors or burnt components on power board.
Repair: Replace faulty power supply board, fuse, or capacitors. Repair solder joints. If mainboard failure, replace mainboard. Test on bench before reinstall.
2. TV turns on but screen is black / no backlight
Symptoms: Power LED on, sound may work, but screen dark; sometimes faint image visible under flashlight.
Diagnosis: Test backlight inverter (older CCFL) or LED driver circuit. For LCD/LED TVs, measure backlight voltage rails and LED strips. Inspect for failing LED strips or driver ICs.
Repair: Replace LED driver board or LED strips. For high-end sets, replace LED backlight assembly. Align and test uniformity after repair.
3. Dim or flickering screen
Symptoms: Brightness fluctuates or dims over time; sometimes flickers when moved.
Diagnosis: Check power supply stability, failing capacitors, loose connectors, or aging LED strips. Inspect backlight driver and T-con board connections.
Repair: Replace failing capacitors on power supply, reseat cables, replace LED strips or driver board as needed. Calibrate brightness.
4. Lines on the screen (horizontal / vertical)
Symptoms: Single or multiple lines across the display, can be static or moving.
Diagnosis: Determine if line is on entire screen (panel/T-con issue) or intermittent (ribbon cable/connectors). Test T-con board and LVDS ribbon cables.
Repair: Reseat or replace LVDS ribbons and connectors, replace T-con board, or — if panel row/column driver failure — replace the panel (more costly).
5. TV shows distorted image or color problems
Symptoms: Colors incorrect (green/red/blue cast), washed out, or image compression artifacts.
Diagnosis: Check mainboard video processing, T-con, panel connectors. Run color calibration tests and check firmware.
Repair: Replace or re-flash mainboard firmware, replace T-con, repair ribbon cables, or panel replacement if pixel drivers are damaged.
6. Sound problem — No audio or distorted audio
Symptoms: No sound despite picture, distorted sound, or intermittent audio.
Diagnosis: Test internal speakers, audio IC on mainboard, analog/digital audio circuits, and external audio output. Check software settings and input sources.
Repair: Replace audio amplifier IC or speaker units, repair mainboard audio circuits, update firmware, or adjust audio settings. Fit external soundbar/AVR if preferred.
7. TV restarts or reboots randomly
Symptoms: TV cycles off and on, reboots during use or at startup.
Diagnosis: Check power supply voltages and thermals, failing capacitors, firmware crashes, or remote control faults causing power toggles.
Repair: Replace faulty power board components, apply firmware update, replace remote or receiver module, and test under load to confirm stability.
8. Remote control not working / no IR response
Symptoms: Remote buttons have no effect; TV only controllable by front buttons.
Diagnosis: Test remote battery, test IR receiver on TV with phone camera or multimeter, check IR sensor connection to mainboard.
Repair: Replace remote or IR receiver module, clean button contacts, or reprogram remote for smart TVs.
9. Overheating / thermal shutdown
Symptoms: TV becomes very hot and shuts down, or shows heat-related artifacts.
Diagnosis: Measure operating temperatures, inspect ventilation, check for blocked airflow, failing power components producing heat.
Repair: Clean ventilation, improve placement, replace power components producing heat, add heat-sinks where appropriate.
10. Smart TV network / app failures
Symptoms: Apps crash, TV won’t connect to Wi-Fi or Ethernet, streaming buffering.
Diagnosis: Check network settings, firmware version, app cache, and network hardware. Run connectivity tests and check DNS settings.
Repair/Service: Update firmware, reset network settings, clear app cache, replace faulty Wi-Fi module or Ethernet jack. Provide guidance for optimal home network setup.
11. HDMI / input port faults
Symptoms: No signal from HDMI devices, intermittent signal, “no signal” or garbled picture from external sources.
Diagnosis: Test with multiple HDMI cables and devices, inspect HDMI port pins for damage, check EDID handshake on mainboard.
Repair: Replace or re-solder HDMI socket, repair mainboard HDMI circuits, update firmware. Recommend high-quality HDMI cables for 4K/HDMI2.1.
12. Ticking, buzzing or electrical noise
Symptoms: Audible noise from power board or speakers, ticking on startup.
Diagnosis: Identify source (power board capacitors, transformer, speaker coils). Use oscilloscope/meter to find ripple or vibration.
Repair: Replace noisy capacitors, secure transformers, add isolation pads, or replace faulty speakers.
13. Ghosting, image retention or burn-in (OLED / plasma)
Symptoms: Afterimages persist on screen, particularly on OLED or plasma sets.
Diagnosis: Identify burn-in vs temporary image retention. Use pixel tests to determine permanent damage.
Repair / Advice: For temporary retention, run pixel-refresh cycles or screen savers. Permanent burn-in may require panel replacement; advise customer on minimizing future burn-in.
14. Physical damage (cracked screen, water ingress)
Symptoms: Visible cracks, black spots, water stains, or complete panel failure after impact or moisture.
Diagnosis: Visual inspection, test for short circuits and corrosion, check other boards for collateral damage.
Repair: For cracked panels—panel replacement (often costly). For water damage—dry, clean corrosion with isopropyl/alcohol, replace affected boards or connectors. Provide cost-vs-replacement guidance.
15. Firmware / software glitches and UI failure
Symptoms: Menus unresponsive, boot loops, app store missing, or software hangs.
Diagnosis: Attempt safe-mode boot, check for firmware updates, inspect eMMC memory for corruption.
Repair: Reflash firmware or reinstall software, replace corrupted storage chip if necessary, or replace mainboard.
16. Picture out of sync with audio / lip-sync issues
Symptoms: Audio delayed or ahead of picture.
Diagnosis: Check audio processing latency, external receiver settings, HDMI ARC/eARC handshake.
Repair / Fix: Adjust AV sync settings, update firmware, ensure correct HDMI ARC/eARC configuration, or replace failing audio processor if hardware fault.
17. TV remote sensors or smart voice controls not responding
Symptoms: Voice assistant or smart control fails to respond or is intermittent.
Diagnosis: Test microphones, network connectivity for cloud-dependent assistants, and sensor hardware.
Repair: Replace microphone/sensor modules, reconfigure voice assistant settings, update firmware.
18. Dead pixels and cluster of bad pixels
Symptoms: Single or clusters of pixels stuck on/off.
Diagnosis: Run pixel test patterns to quantify dead/stuck pixels. Determine if it’s within manufacturer tolerance.
Repair: For stuck pixels, pixel massaging / software may help. For many dead pixels, panel replacement may be needed; advise based on cost.
19. Color banding or lines after firmware update
Symptoms: New artifacts after a system update.
Diagnosis: Confirm if update corrupted display LUTs or color processing, revert to previous firmware if available.
Repair: Reflash firmware, recalibrate color profiles, replace mainboard if processing hardware damaged.
20. Intermittent display or image breakup during use
Symptoms: Picture breaks up at certain angles or times.
Diagnosis: Test with multiple inputs, check internal flex cables, connectors, and solder joints for microfractures.
Repair: Re-solder joints, replace weak cables/connectors, replace boards if required.
