How to detect the component that caused the failure? (T-con, PSU, Mainboard, backlight, LCD panel...)

Summary of power board related faults:

✅ TV doesn't turn on at all → Swollen capacitors, short circuit, blown fuse.
✅ Standby LED flashes or absent → Voltage regulation fault, main power supply failure.
✅ No backlight → Backlight power supply out of order, transformer or LED driver broken, LED bars should also be checked.
✅ TV turns off after a few seconds → Protection against short circuit or overheating, unstable voltage problem.

❌ TV turns on but immediately turns off → Can also be caused by the motherboard or a short circuit in the panel.

Summary of motherboard related faults:

✅ TV on but black screen (with active backlight) → Firmware problem, corrupted EEPROM, or HS GPU.
✅ TV does not respond to buttons or remote control → Motherboard stuck, NAND memory problem.

✅ TV reacts to the remote control but screen remains black and you can hear the sound, no image even with the help of a lamp → Motherboard image circuit broken

✅ Freeze frame or visual artifacts → Damaged video processor, defective RAM memory.
✅ No sound but picture OK → Audio circuit broken, amplifier or headphone output shorted.

❌ No image or backlight → Can also come from the power supply or LED backlighting, often visible with the help of the flashlight even in very dark conditions

Summary of faults related to LED bars:

✅ No backlight but image visible with a lamp → Burnt out LEDs or defective LED power supply.
✅ Flashing or partial backlight → One or more LEDs broken, LED driver problem.
✅ Dark spots or darker areas on the screen → Some LEDs are weak or defective.
✅ TV turns off after a few seconds → Power supply protection if too many LEDs are burned out.

❌ Totally black screen (even with flashlight) → Can also come from the T-CON card or the motherboard.

Summary of T-CON related outages:

✅ Vertical lines → T-CON problem, LVDS connectors, or defective gamma circuit.
✅ Half screen displayed → T-CON problem or LVDS connector poorly connected.
✅ No image at all but backlight OK → T-CON HS or blown fuse.
✅ Distorted colors → Faulty IC gamma circuit on the T-CON.

❌ Horizontal lines → Often LCD panel problem, poor connection of the COF layers, or irreparable internal fault.
