Introduction 1. Basic concept of how to determine the defective board 1) Verification of voltages Normally, when there is a power problem, shutdown occurs immediately. So, to resolve a power problem, voltage checks are necessary before shutdown. 2) Check if the power comes up after disconnecting the board under suspicion. If power comes up (*) after disconnecting a board, the board is defective.
Troubleshooting Shutdown Problems CAUTION: Some steps require removal of connectors and sometimes PC boards removal. Do not let the TV run for more than 30 seconds while connectors or boards are disconnected. Slide #8...
Power LED’s Response to Shutdown Operation When an abnormality occurs in the TV, the “SOS Detect” circuit is triggered and the TV shuts down. The power LED on the front panel will flash a pattern indicating the circuit that has failed.

SU and SD Boards Visual Inspection Check the ICs on the SU and SD boards for blown hole on the surface. Note: In some models it is not possible to check if these ICs are blown because they use surface-mount heat sinks that are glued to the surface of the ICs.
SU,SD, and SC Boards Resistance Test Procedure SU,SD, and SC Boards Resistance Test Procedure Note: The result of the resistance test determine if the boards are bad, but it does not determine if they are 100% good. For this reason, after performing a resistance test, we need to further check the boards that check OK using another procedure.
SU Board Resistance Test (All Models) Preparation: Disconnect AC Power prior to making any disconnection or connection. Wait at least 2 minutes before the removal of any connector.
