SONY TV POWER BOARD REPAIR & REPLACEMENT SERVICES IN NAIROBI – PRO-LOGIC TECHNOLOGIES LIMITED
Is your Sony television completely dead, refusing to power on, clicking repeatedly, restarting, or showing no standby light? The problem may be within the TV's power supply board (SMPS).
The Sony power board shown above is an example of the type of power-supply circuit we diagnose and repair. At Pro-Logic Technologies Limited, we handle Sony TV power-board troubleshooting, component-level repair, testing, and replacement where necessary.
SONY TV POWER SUPPLY BOARD REPAIR
A television power board converts incoming AC electricity into the different regulated DC voltages required by the TV's main board, LED backlight system and other circuits. When this section develops a fault, the entire television can appear dead even when the screen itself is perfectly healthy.
We diagnose faults involving:
- Power supply boards
- Switching power supplies
- Standby power circuits
- Primary-side switching circuits
- Secondary voltage circuits
- Power MOSFETs
- Rectifier diodes
- Bridge rectifiers
- Fuses
- Capacitors
- Transformers
- Regulators
- Startup circuits
- Protection circuits
- Burnt components
- Short circuits
- Over-voltage and under-voltage conditions
- AC input and filtering sections
COMMON SONY TV POWER PROBLEMS
SONY TV COMPLETELY DEAD

If there is no standby indicator and the television gives absolutely no response, the power supply should be among the first areas to investigate.
We test the AC input, fuse, rectification stage, standby supply and other relevant sections before deciding whether the board needs repair or replacement.
SONY TV HAS NO STANDBY LIGHT
A missing standby light can be caused by a failure in the standby power circuit, although other television circuits can also produce similar symptoms.
Proper voltage measurements and circuit diagnosis are therefore important before replacing expensive boards.
SONY TV CLICKS BUT DOES NOT START
Repeated clicking can occur when the power supply attempts to start and then enters protection because of an abnormal voltage or excessive load.
The fault may involve the power board itself or another circuit connected to it. We diagnose the complete power path rather than replacing parts blindly.
SONY TV TURNS ON AND OFF
If your Sony TV starts and then shuts down, possible causes include unstable power supply output, protection activation, excessive loading, LED backlight faults or problems elsewhere in the television.
Our technicians test the relevant circuits to establish the actual cause.
COMPONENT-LEVEL POWER BOARD REPAIR
Not every faulty Sony power board needs to be replaced completely.
Depending on the condition of the PCB, we can inspect and repair individual components such as:
- Switching transistors
- MOSFETs
- Diodes
- Capacitors
- Resistors
- Regulators
- Controllers
- Transformers
- Protection components
- Rectifier components
- Startup components
- Burnt or damaged sections
Component-level repair can be appropriate where the PCB is otherwise serviceable.
SONY POWER BOARD REPLACEMENT
Where repair is not technically or economically appropriate, we can help identify a compatible replacement board.
Do not order a Sony power board based only on appearance. Two boards can look almost identical while having different part numbers, voltage configurations, connectors or circuit revisions.
We normally verify the television model and the markings on the existing board before recommending a replacement.

BRING YOUR SONY TV FOR PROPER DIAGNOSIS
If your Sony television has stopped working, avoid repeatedly switching it on when there may be a short circuit or power-supply fault.
Bring the television for professional diagnosis so the technician can determine whether the problem is actually on the power board or another section.
