How to Fix 8 Blinking Error Sony KLV-32S400A
Introduction
If your Sony KLV-32S400A TV flashes the red light 8 times and does not turn on, it typically indicates a fault in the power supply board.
In this article, we will walk you through a step-by-step method to diagnose and repair this 8 blinking error effectively.
Understanding the 8 Blinking Error
Sony TVs use red light blinking codes to signal different types of hardware failures.
For the KLV-32S400A model, 8 blinking errors usually point toward a voltage drop or a faulty component in the power supply section.
Fault Diagnosis
- The TV’s back cover was removed to inspect the power supply board.
- Upon checking, the 12V output voltage initially appeared normal but dropped to around 8–8.5V after a few seconds.
- A close inspection near the main IC, CXD9841P (chassis marking IC6104), revealed a faulty capacitor labeled C6142.
Faulty Component Replacement
- The faulty capacitor C6142 had a value of 47µF.
- After replacing this capacitor with a new one of the same value and voltage rating, the TV was
- powered on again — and it worked perfectly without any blinking errors.

In the image provided below, the faulty capacitor C6142 and the main IC CXD9841P (IC6104) are clearly marked.
This marking will help you easily locate and replace the defective component during your repair.
Important Tips for Repair
Always match the capacitor’s value and voltage rating exactly when replacing.
Follow proper safety precautions while working on the power supply board.
Double-check the surrounding circuitry for any other hidden faults to avoid future issues.
Conclusion
The 8 blinking error in the Sony KLV-32S400A is often caused by a voltage drop in the power supply board.
With correct fault-finding techniques and timely replacement of faulty parts like capacitor C6142, this issue can be resolved efficiently.
We hope this guide helps you fix the problem with ease.
