ALL common television problems — explained, diagnosed, and repaired (step-by-step)

Below we list the most common TV faults, each explained clearly with GossTech’s diagnostic checklist and repair steps. Use this as a quick guide — for best results, book a technician for hands-on diagnosis.

1. TV won’t turn on (no power)

Symptoms: No LEDs, dead screen, no click when pressing power.

Common causes: Faulty mains lead, blown fuse, defective power supply board (SMPS), bad capacitors, failed standby circuit, remote control issues.

GossTech diagnosis process

Verify mains supply and test with multimeter.
Inspect mains lead and plug for continuity.
Open rear cover (if on-site) and visually inspect power board for bulging/leaking capacitors or burned components.
Measure standby voltage rails and test fuse and surge survivor components.

Repair steps

Replace blown fuses and surge components.
Replace faulty capacitors and regulators on the SMPS.
If the entire power board is dead, fit a tested replacement board (match model + serial).
Test full power-up sequence; burn-in test 30–60 minutes.
Provide warranty and return.

2. TV has power but shows a black screen (backlight failure)

Symptoms: Power LED on, sound present, image barely visible if you shine light on screen.

Common causes: Backlight LEDs/CCFL failure, inverter board fault (for older CCFL sets), T-con board or main board sending no signal to backlight.

GossTech diagnosis process

Confirm audio present (if yes, video path is likely issue).
Use flashlight test to check for faint image.
Measure LED/backlight strings for continuity and voltage.
Check inverter board (older LCD CCFL sets) or LED driver circuits (modern LED TVs).

Repair steps

Replace failed backlight LED strips or CCFL tubes.
Replace/repair inverter or LED driver board.
Replace T-con board if it’s the signal path issue.
Reassemble and test brightness & uniformity.

Calibrate panel after fitment and test for dead pixels and backlight uniformity.
If replacement is uneconomical, advise customer on alternatives.
