Complete list of common television problems — one by one (diagnosis + GossTech repair approach)
Below is a comprehensive list of TV faults we encounter. Each entry explains the symptom, how GossTech diagnoses it, and the typical repair path we follow.
1. TV won’t power on (no lights / dead)
Symptom: No LED indicator, completely unresponsive.
Diagnosis: Check mains, power cable, IEC connector, power board (fuses, swollen capacitors), internal safety switches, standby supply voltage. We use a multimeter and bench PSU for controlled testing.
Repair: Replace blown fuse(s), repair or replace faulty power board components (capacitors, diodes, regulators). If the main board is shorted, we assess cost vs replacement. We always explain options before proceeding.
2. TV powers on but screen is black (audio OK)
Symptom: You hear sound but no picture.
Diagnosis: Check backlight (LED/CCFL) operation, inverter or LED driver board, T-CON board, LVDS cable connection between main board and panel. Use lamp/inverter tester and LED current checks.
Repair: Replace failed LED driver or inverter board; replace LED strips if necessary; reseat or replace T-CON cable/board. Where the panel itself is faulty (rare), we provide replacement options and quote.
3. Dim or uneven brightness / backlight flicker
Symptom: Picture visible but dim, patchy, or flickering.
Diagnosis: Measure LED string voltages and currents, inspect LED strips for open circuits, test backlight driver for ripple/instability.
Repair: Replace faulty LED strips or driver board; clean connectors; secure cooling/ventilation to prevent heat-induced flicker.
4. Lines across the screen (horizontal or vertical)
Symptom: Persistent single or multiple lines across display.
Diagnosis: Inspect ribbon cables (T-CON), test T-CON board signals, check panel row/column drivers.
Repair: Reseat or replace T-CON board or ribbon cable; replace panel driver IC if board-level repair feasible; panel replacement as last resort.
5. Color problems (washed, wrong colors, tint)
Symptom: Colors missing (no red/green), oversaturated or wrong tint.
Diagnosis: Run color pattern tests, inspect color processing circuits on main board or scaler, check screen LUT and calibration, identify faults in color ICs.
Repair: Replace/repair faulty components on the main/scaler board, update firmware, or perform color calibration. For cheap panels, replacement board may be more cost-effective.
6. Audio issues (no sound, distorted sound)
Symptom: No sound, low volume, distortion, or one speaker not working.
Diagnosis: Test internal speakers, amplifier circuit, audio IC on main board, external audio output and HDMI-ARC.
Repair: Repair amplifier circuitry, replace speakers, fix board traces, clean connectors, update audio firmware or reset audio configurations.
7. TV turns on and off randomly (power cycling)
Symptom: TV reboots or shuts off unexpectedly.
Diagnosis: Check power supply voltages for instability, thermal shutdown, failing capacitors, sleep timer or ECO settings, and external HDMI-CEC signals.
Repair: Replace failing capacitors or power supply parts, repair thermal sensors, advise on firmware settings; if caused by connected devices (HDMI-CEC), reconfigure.
8. Remote control problems / buttons not working
Symptom: Remote unresponsive or intermittent.
Diagnosis: Test remote battery and IR/BT signal, check TV’s IR receiver or Bluetooth module.
Repair: Replace remote or IR sensor; re-pair or replace front-panel IR receiver; pair new Bluetooth remotes for Smart TVs.
9. HDMI / input port problems (no signal)
Symptom: “No signal”, intermittent input, or poor picture from HDMI devices.
Diagnosis: Test with multiple HDMI cables and devices, inspect HDMI port solder joints, check EDID negotiation.
Repair: Reflow or replace damaged HDMI ports, update TV firmware, replace main board if port is integrated and damaged.
10. Smart TV app failures / Wi-Fi not connecting
Symptom: Apps crash, cannot download updates, or TV won’t connect to Wi-Fi.
Diagnosis: Network tests, firmware version check, internal storage health, and app cache issues.
Repair: Firmware/OS updates, factory reset with data backup, Wi-Fi module replacement or Ethernet workaround, clear app cache and reinstall apps.
11. Ghosting / image retention / burn-in (especially OLED/PLASMA)
Symptom: Ghost images or static logos remain.
Diagnosis: Distinguish between temporary image retention and permanent burn-in; run panel refresh and pixel-shift diagnostics.
Repair: Use pixel refresh cycles, lower brightness and static UI elements, recommend replacement only for permanent burn-in (rare with modern panels).
12. Tuner / channel reception problems
Symptom: Missing channels, poor reception.
Diagnosis: Test with known good antenna, check internal tuner module and RF connectors, scan channel list.
Repair: Replace tuner module, repair RF connectors, recommend or install a better antenna or set-top box as needed.
13. USB / Media playback failures
Symptom: TV won’t play videos from USB or TV reports unreadable media.
Diagnosis: Check file formats, USB file system, USB port power, and firmware compatibility.
Repair: Reformat USB to supported file system (after data backup), repair/replace USB port, update firmware to add codec support.
14. Cracked or physically damaged screen
Symptom: Visible crack, dead pixels, bleeding.
Diagnosis: Inspect panel damage; determine if damage is localized or affects panel driver circuits.
Repair: Panel replacement quoting cost; if repair not cost-effective we advise replacement options and salvage parts where useful.
15. Burning smell / smoke
Symptom: Smell of burning, visible smoke, or smoke residue.
Diagnosis: Immediate power down and visual inspection of power board, transformers, capacitors, and connections. Safety first.
Repair: Replace scorched components and boards; test insulation and safety circuits; in severe cases recommend replacement for safety.
How GossTech diagnoses — our step-by-step process

- Bench diagnostics: For board-level or complex faults we bring the TV or its boards to our workshop for component-level testing with oscilloscopes, ESR meters, lamp testers, and bench PSUs.
- Detailed quote & options: After diagnosis we give a clear quote and explain whether repair, part replacement, or panel replacement is recommended. We provide options (original parts vs quality aftermarket) and warranty terms.
- Repair & validation: Repair, parts replacement and a comprehensive test including stress test, channels, apps, HDMI devices, and audio/video sync checks.
- Aftercare: Advice for safer use and maintenance, plus limited warranty on parts/labor where applicable.
