There could be a number of reasons why your Alba TV is turning off after just a few seconds. Some common causes include:
- Power supply issues: If the power supply to the TV is not stable, it can cause the TV to turn off. Check if there are any loose connections or faulty cables.
- Overheating: If the TV is overheating, it can shut off to protect itself. Ensure that the vents and fan are clear of any obstructions and the TV is not in a location that is too hot.
- Faulty remote: Sometimes, a faulty remote can cause the TV to turn off by itself. Try removing the batteries from the remote and see if the issue persists.
- Faulty hardware: If the TV's hardware is faulty, it can cause the TV to turn off. This could be due to a number of reasons, such as a defective power supply or a malfunctioning circuit board.
If none of these solutions work, it's possible that the TV is defective and needs to be returned for a replacement or repair.
