What could be the cause of vertical lines appearing on the screen after turning on a device, especially after the motherboard has been replaced, accompanied by the LED blinking twice then three times repeatedly?
The blinking LED suggests a fault. A double blink could indicate a panel issue. Steps to take include verifying the Soc T-CON pattern in factory mode if there is video noise, checking or replacing cables if the noise only appears on half the screen, and ensuring the cables and main circuit/TV panel are not defective. If replacing the motherboard didn't solve the problem, the issue might be with the panel itself or another component.

What does it mean when a Samsung LED TV's power light flashes red, the screen is black with no backlight, and there is no sound?
This likely indicates an issue with the SMPS (power supply) module. The red flashing light is an error code pointing to the SMPS. The fact that the backlight turns on and the red light turns off when disconnecting the mainboard from the SMPS confirms that the power supply is likely the source of the problem.

What should be checked when suspecting a faulty SMPS module in a Samsung LED TV?
Ensure that the connections between the mainboard and the SMPS board are clean and secure. If possible, use a multimeter to measure the output voltage of the SMPS. An incorrect voltage reading would confirm an issue with the SMPS.

What to do when a UE65AU7105KXXC TV screen is black and blinking 5 times on a cold start?
A black screen blinking 5 times on a cold start typically indicates an issue with the main board. Check all cable connections (power, HDMI, etc.) to ensure they are secure and unobstructed. Power cycle the TV by unplugging it from the wall for at least 30 seconds. Ensure proper ventilation to prevent overheating. As a last resort if accesible, attempt a factory reset.
