Sony 1-474-710-11 Power Supply Board

This is a genuine, manufacturer-sourced component salvaged from a television with a damaged panel. Because it is pulled from an existing unit, it is considered a used, original part rather than new-in-box stock.

Symptoms like the TV failing to turn on, intermittent power loss, or standby lights blinking in specific patterns often point to a power supply issue. However, we strongly recommend performing a voltage test or consulting a service manual before purchasing, as other internal boards can mimic these symptoms.

Yes, these part numbers are typically interchangeable revisions of the same component. You can safely use either version for the compatible XBR-49X900F model.

We advise against DIY installation unless you are comfortable working with internal electronics. The process involves handling sensitive components and high-voltage capacitors, which can be dangerous if not managed correctly.

If the replacement board does not resolve the issue, it is likely that the fault lies with another component, such as the main board or the LED backlight array. We recommend a thorough diagnostic check of all internal systems before assuming the new power supply is defective.
