Check whether audio continues when the screen goes dark.
Isolate backlight, power supply, video source and panel faults.
QLED and Mini-LED TV
Quantum dots improve colour on QLED models. Mini-LED describes a backlight technology.
Record whether uneven brightness appears on the home menu and all inputs.
Assess backlight zones, controls and panel behaviour.
OLED TV
Individual pixels emit light without a separate backlight.
Distinguish temporary image retention from persistent marks across inputs.
Check image processing and panel condition before discussing economics.
Smart TV
Built-in apps and network functions can fail separately from picture hardware.
Compare streaming, menu and HDMI behaviour.
Check network settings, software and main board symptoms.
Plasma and CRT TV
Older designs use different display technologies and parts.
Share the exact model and whether the problem started suddenly.
Confirm safe handling, parts availability and workshop feasibility by phone.
Common repair enquiries
No power
Record standby light behaviour and any clicking. Diagnosis separates input power, standby circuits and startup faults.
Lines or half picture
Check whether lines also appear on the built-in menu. The technician can evaluate panel, connector and processing faults.
Sound without picture
Audio continuing with a dark image helps narrow diagnosis. LCD backlights and OLED panel systems need different checks.
HDMI and Wi-Fi faults
Test one known working source or compare the home menu before booking. Share the app or input affected.
LED backlight replacement
Check for sound with a dark screen and confirm whether backlight strips or their driver have failed.
Power supply and main board
Inspect standby behaviour, boot loops, input faults and power interruptions before recommending a board repair or replacement.
Display panel assessment
Check cracks, persistent lines and half-screen faults. Discuss panel availability and whether the estimate makes sense for the TV.
Speaker and input diagnosis
Compare built-in sound and external inputs to separate speakers, ports, software and source equipment.
