Common Hisense TV Issues

Before diving into the details of power supply board replacement, it's essential to identify some common issues that might indicate a malfunctioning power supply:

1. TV Won't Turn On: If your Hisense TV is unresponsive and won't power on, it could be due to a faulty power supply board.
2. Intermittent Power Loss: If your TV powers off randomly and turns back on, this could be a sign of an issue with the power supply.
3. No Picture or Sound: If your TV has no picture or sound but the power indicator light is on, the power supply board could be the culprit.
4. Flickering Screen: A flickering screen or distorted images can also point to a power supply problem.

Diagnosing a Faulty Power Supply Board

To diagnose a power supply board issue, you’ll need to perform a few tests:

1. Visual Inspection: Open the back panel of your TV and inspect the power supply board for any visible signs of damage, such as burnt components or swollen capacitors.
2. Voltage Test: Use a multimeter to check the voltage output of the power supply board. Compare the readings with the specifications listed in the TV's manual. If the voltages are incorrect, the board may be faulty.
3. Component Testing: Test individual components like fuses, diodes, and capacitors for functionality. Replace any damaged components if necessary.
