A labeled overview of major assemblies and how they relate to the symptoms you can observe.

Which symptoms are useful to report?
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.
