What to Do When Your Sony XBR-75X850C TV Won't Turn On After a Power Surge?

Understanding Your Sony XBR-75X850C TV Issue

When dealing with a malfunctioning TV, especially after a power surge, it’s essential to identify the root cause of the problem. In your case, it seems the TV has stopped working entirely, indicated by the power indicator light not lighting up.

Possible Causes of the Issue

1. Power Supply Board Failure: This is the most common issue after a power surge. When the power supply board fails, the TV may not receive any power, resulting in a completely unresponsive unit.

2. Integrated Main Board: In some models, the power supply is integrated into the main board. If this is the case, it complicates repairs as replacing just the power supply may not be sufficient.

3. Other Component Failures: There could also be damage to other internal components, but these are often less common with power surges.

Is Rebuilding Necessary?

From your communication with repair shops, it appears they suggested that the TV needs to be "rebuilt." This often implies replacing significant portions of the internal circuitry or main board. Here are some points to consider:

• Integrated Components: If the power supply is indeed integrated with the main board, complete replacement might be necessary. However, this can be costly and may not be the best option if you can find alternatives.
