Restore Power to Your Dead Television
Power fluctuations, thunderstorms, and voltage spikes across Mumbai's electrical grid frequently damage the sensitive Switch Mode Power Supply (SMPS) board inside modern LED and 4K TVs.
The power board is responsible for converting 230V AC mains electricity into tightly regulated low-voltage direct current (DC) rails: +12V, +24V, +5V, and 3.3V standby voltages. When high-voltage filter capacitors explode or switching MOSFETs burn out, the television goes into safety shutdown or fails completely.
Common Power Fault Symptoms We Fix
- TV Totally Dead (No Red Standby Light): The primary fuse has severed due to a shorted bridge rectifier or power oscillator IC.
- Red Standby LED Blinking (2 to 6 Times): Modern Sony, Samsung, and Panasonic TVs feature self-diagnostic error blink codes indicating power rail failure.
- Clicking Relay Noise: The power relay clicks ON and immediately clicks OFF as short-circuit protection kicks in.
- TV Turns Off Automatically After 5–10 Minutes: Thermal degradation of power capacitors under heat stress.
- Burnt Smell or Sparking Noise: Moisture or dust causing high-voltage arcing on the underside of the PCB.
