Notes (*):
•
When the TV is in stepwise mode and, due to stepping-up,
a protection is activated, the TV will really go into protection
(blinking LED). The TV will not leave the stepwise mode
however. If state X is the state where the TV went to
protection, stepwise start-up will return to state X-1. At
state (X-1) diagnostic measurements can be performed.
Also, in the short time the TV is in state X but not yet in
protection, you can also do some measurements.
•
Stepwise start-up can NOT be used for Samsung displays
(SDI). The TV will not react in a proper way, due to other
timing specifications.
