Samsung LCD TV Power Supply Circuit Diagram

The power supply circuit of a Samsung LCD TV is a complex and critical component that provides the necessary voltage and current to the various components of the TV. It is responsible for converting the AC power from the wall outlet into the DC power that the TV needs to operate. The power supply circuit also includes a number of safety features to protect the TV from damage.

The power supply circuit of a Samsung LCD TV typically consists of the following components:

  • A transformer to convert the AC power from the wall outlet into a higher voltage AC.
  • A rectifier to convert the higher voltage AC into DC.
  • A filter to smooth out the DC output of the rectifier.
  • A voltage regulator to provide a stable DC output voltage.
  • A power switch to turn the TV on and off.
  • A fuse to protect the TV from damage in the event of a power surge.

The power supply circuit is typically located on the back of the TV, near the power cord. It is a large, metal box with a number of components inside. The power supply circuit is often covered by a metal shield to protect it from damage.

The power supply circuit is a critical component of a Samsung LCD TV. If the power supply circuit fails, the TV will not turn on. In some cases, a faulty power supply circuit can also damage other components of the TV.

If you suspect that the power supply circuit of your Samsung LCD TV is faulty, it is best to have it repaired by a qualified technician. Attempting to repair the power supply circuit yourself could be dangerous and could void your warranty.
