The error buffer will automatically be erased if its contents haven't changed in the last 50 hours of use (run timer
count). This is to prevent an error buffer full of codes which are not valid.
Manual erasure of the buffer is possible through:
l
ERASE BUFFER (SAM mode only) command from the remote control
l
exiting SDM or SAM by pressing the Power button on the remote control or the television set
To save error codes, remove ac power. When ac power is reapplied, the chassis will be on, in SAM or SDM,
and the error codes may be viewed again.
A blinking LED may indicate a current error. The error code can be determined by counting the "off" blinks.
