Power Supply Problems

Power supply issues are among the most common reasons for seeking Sony TV repair service. The power supply board is responsible for converting AC power from your wall outlet into the various DC voltages required by different TV components. When this crucial component fails, it can lead to a range of symptoms, from complete power loss to intermittent operation. Addressing power supply problems often requires careful diagnosis and sometimes component-level repairs.

No Power Symptoms

• TV won’t turn on: The most obvious sign of a power supply issue is when the TV fails to power up at all.
• Standby light not illuminating: If the standby LED doesn’t light up, it could indicate a problem with the power supply.
• Clicking sound without power: A repetitive clicking noise without the TV turning on often points to power supply failure.
• Brief power-on followed by shutdown: The TV may attempt to start but quickly turns off due to insufficient power.

---

Intermittent Power Issues

• TV randomly turns off: Sudden shutdowns during operation can be caused by an unstable power supply.
• Fluctuating brightness: If the screen’s brightness varies unexpectedly, it may indicate power supply voltage irregularities.
• Delayed start-up: A significant delay between pressing the power button and the TV turning on can suggest power issues.
• Standby mode problems: Difficulty entering or exiting standby mode may be related to power supply malfunctions.

---

Power Supply Board Inspection

• Visual examination: Look for bulging or leaking capacitors, burnt components, or signs of electrical arcing on the board.
