All Common Television Problems — Full List with Diagnosis & Repair Approach
Below is a detailed breakdown of television faults we commonly encounter. Each entry lists the symptoms, how GossTech diagnoses the issue, and our standard repair approach.
1. TV won’t power on (no lights, dead)
Symptoms: No standby LED, no sound when power pressed, completely dead.
Diagnosis: Check mains and remote batteries → test wall socket → measure DC rails on SMPS (power supply board) → look for bulging capacitors, blown fuses, shorted diodes or burnt traces.
Repair: Replace failed capacitors, diodes or fuses; repair PCB traces; replace power board if beyond repair. Test on bench then final in-place test. Provide warranty on replaced parts.
2. TV turns on but shows black screen / no backlight
Symptoms: Sound plays but screen is black / very dim or only visible under flashlight.
Diagnosis: Distinguish between backlight failure (LED strips/inverter) vs. video signal issue (T-CON / main board). Test backlight with multimeter and small flashlight trick; measure LED driver voltages; read T-CON error codes.
Repair: Replace LED backlight strips or inverter/LED driver board; replace/repair T-CON board; reflow connectors, secure LVDS ribbon cable; final calibration.
3. TV powers off randomly or after a short time (auto-shutoff)
Symptoms: TV on then suddenly shuts down; may reboot.
Diagnosis: Look for overheating, failing capacitors in power supply, firmware/OS watchdog crashes, or faulty sensors. Run prolonged stress test and monitor voltages.
Repair: Replace aged capacitors, clean vents and fans (if present), update firmware, repair or replace faulty power board or main board.
4. No sound or distorted audio
Symptoms: No audio, low volume, crackling or distorted sound.
Diagnosis: Test using internal speakers and external audio output; check audio ICs on main board, speaker connections and speaker units. Run audio diagnostics via service menu.
Repair: Replace faulty speakers, repair speaker wires, replace audio IC or main board if necessary. For Smart TVs, check sound settings and firmware before hardware replacement.
5. Lines on screen — horizontal or vertical lines
Symptoms: Thin horizontal/vertical lines across picture; can be flickering.
Diagnosis: Check T-CON board and LVDS cable; inspect display panel for physical damage; test ribbon connectors and flex cables.
Repair: Re-seat or replace T-CON board; replace LVDS ribbon cable; in panel failure replace the panel (expensive) — we provide transparent cost/benefit analysis.
6. TV shows “No Signal” or intermittent signal
Symptoms: “No Signal” message or picture drops when using HDMI/AV.
Diagnosis: Check source device, HDMI cables and ports, test multiple inputs; inspect main board HDMI ports for damage; test firmware compatibility and HDCP errors.
Repair: Replace faulty HDMI port/module; update firmware or advise compatible cable; repair main board; test with multiple sources.
7. TV apps or Smart TV features not working / frozen OS
Symptoms: Apps crash, remote control not responding to Smart TV menus, slow UI.
Diagnosis: Check internet connectivity, run firmware/OS diagnostics, check available storage and logs, test remote sensors.
Repair: Soft reset and firmware update; factory reset and cache clear; if eMMC/storage is failing replace or repair main board; replace remote sensor if needed.
8. TV remote not working
Symptoms: TV doesn’t respond to remote though remote works on other TVs or vice-versa.
Diagnosis: Check batteries, IR receiver on TV (test with phone camera), pair Bluetooth remotes if applicable, test remote with multimeter or remote tester.
Repair: Replace infrared/bluetooth receiver module or remote; re-pair/bind remote; replace remote control if faulty.
9. Picture is fuzzy, blurry, wrong colours or color tint
Symptoms: Colour balance off, green/pink tint, oversaturated or washed-out image.
Diagnosis: Inspect color processing circuits, test HDMI input settings, calibrate color profiles, check for panel aging effects.
Repair: Adjust settings, perform color calibration, replace faulty main or T-CON board, replace panel if color columns failing.
10. Burn-in or permanent image retention (OLED/Plasma)
Symptoms: Ghost images permanently visible, especially on OLEDs and plasmas.
Diagnosis: Distinguish temporary image retention vs permanent burn-in using test patterns and pixel refresh logs.
Repair: For temporary retention use panel refresh, pixel cleaning — permanent burn-in often requires panel replacement. We advise on prevention and detect early.
11. Lines of dead pixels or blocky artifacts (pixel faults)
Symptoms: Dead or stuck pixels or blocky compression artifacts.
Diagnosis: Run pixel tests; determine whether panel-level defects exist.
Repair: Small stuck pixels sometimes recover with software routines; most dead pixels require panel replacement. We evaluate warranty viability.
12. TV LED indicator blinking error codes
Symptoms: LED blink patterns (e.g., 2 blinks / 5 blinks) on power board.
Diagnosis: Interpret manufacturer-specific blink codes to locate fault (supply, backlight, main board). Use service manuals and in-house diagnostic database.
Repair: Replace the indicated failing board/component as confirmed by tests.
13. Wireless (Wi-Fi/Bluetooth) not connecting
Symptoms: TV won’t connect to home Wi-Fi or Bluetooth devices.
Diagnosis: Test modem, router and TV network module; run network scan; check software versions and signal strength.
Repair: Update firmware; reconfigure network; replace internal Wi-Fi/Bluetooth module or external USB adapter if supported.
14. Distorted or missing channels (for DVB/T2 or satellite)
Symptoms: Channel dropouts, pixelation during broadcast.
Diagnosis: Check antenna/cable, tuner module on TV, perform channel rescan, check LNB/cabling for satellite.
Repair: Replace faulty tuner module, repair coax connectors, align antenna/LNB, replace RF input board.
15. Physical damage (cracked screen, water damage)
Symptoms: Visible cracks, liquids spilled; screen doesn’t turn on properly.
Diagnosis: Assess the panel condition, internal board damage, corrosion.
Repair: Panel replacement for cracked screens (quoted separately); corrosion cleaning, board repairs possible after full assessment. We give a no-surprise estimate.
16. Overheating / fan or thermal problems
Symptoms: TV becomes hot, shows overheating messages, performance drops.
Diagnosis: Check cooling vents, thermal pads, power draw, and failing components causing heat.
Repair: Clean vents, replace thermal pads, repair/replace heat-generating components; reconfigure placement advice.
17. Power surge or lightning damage
Symptoms: TV dead or with burnt components after power spike.
Diagnosis: Inspect for charred components, measure input circuits, test surge protection failure.
Repair: Replace damaged power board/TV sections; advise and install surge protectors.

Maintenance Tips to Extend Your TV’s Life
- Keep vents clear; do not enclose the TV tightly.
- Use a high-quality surge protector; voltage spikes are common.
- Avoid leaving static images on OLEDs for long periods to reduce burn-in risk.
- Clean the screen with a microfiber cloth and manufacturer-recommended cleaner.
- Schedule a basic check-up if you notice slowed Smart TV performance — firmware updates can help.
Warranty & Parts Policy
- All replaced parts come with a written warranty (length varies by part).
- Labour warranty for repairs is provided and documented on the job card.
- We keep an inventory of original-equivalent and genuine parts; availability varies by model — we will inform you on the estimate.
FAQs
Q: Do you repair TVs under warranty?
A: If your TV is still under the manufacturer’s warranty, we will advise whether the warranty covers the fault and help you follow the manufacturer process. For out-of-warranty sets we provide transparent paid repairs.
Q: How long does a typical TV repair take?
A: Simple repairs (remote, simple board components) can be same-day. Board-level or panel replacements can take 2–7 business days depending on parts availability. We always give a quoted turnaround on inspection.
Q: Do you provide on-site repairs in Westlands?
A: Yes — Westlands is a core coverage area. On-site is often faster for faults like power board replacement, HDMI port repair, backlight replacement.
Q: What if the panel is damaged — do you replace it?
A: Panel replacement is expensive and sometimes not cost-effective for older TVs. We provide a clear cost comparison and recommend the best commercial decision.
