LED Error Codes
The power button on the television’s front panel includes a blue LED that operates as follows:
•
The LED flashes when the television is initially powering on.
•
The LED remains on when the television is on.
•
The LED shuts off when the television is powered off.
The blue LED also provides an error indicator. If the LED flashes other than when the television is powering on,
this means an error has occurred. You can identify the type of error by observing the number of flashes – see
