KDL-40/46/52Z4500 (CH) 15
4-4. Temp Error (RED 7 times blink)
• This indicates high temperature inside chassis.
IC5507 on BGC board is monitoring temperature.
IC5507 is controlled by MOUTON micro.
• When it happens:
– Check chassis environment.
– Check around IC5507 and replace BGC board if temperature monitoring circuit
has problem.
– Check panel.
4-5. Audio Error (RED 8 times blink)
• This indicates Audio Error (Protection).
• It happens:
– IC8200 on BGC board, Audio Amp detects over current, thermal shut down
and/or low voltage of itself.
– DC voltage detected for audio line.
– MOUTON micro Pin5 Normal condition: High / Error case: Low
• Check UNREG15V at CN6401 Pin4 and Pin5 on BGC board
.
And F3401 on BGC board has 13V or not.
• Check above and replace BGC board.
