Common TV Symptoms Fixed

A diagnosed power-supply board failure may cause the following symptoms:

• TV will not turn on.
• No standby light or no response to the power button.
• TV powers off unexpectedly or has intermittent power.

These symptoms can also have other causes. Confirm the faulty component before replacing the board; replacement is not a guaranteed fix based on symptoms alone.

Fitment & Ordering Guidelines

Verify EAY65920751 on the original board's white sticker, PCB/board number LGP4350B-25U1, the full TV model suffix, and the corresponding version code above. Compare connector locations and board layout before installation. Do not order by screen size or visual similarity alone.

Disconnect the TV from AC power before service. Power-supply capacitors can retain dangerous voltage after unplugging; installation should be performed by a qualified technician. Use appropriate ESD protection and handle the board by its edges.
