5.3
Stepwise Start-up
When the TV is in a protection state due to an error detected by
stand-by software (error blinking is displayed)
and
SDM is
activated via shortcutting the SDM solder path on the SSB, the
TV starts up until it reaches the situation just before protection.
So, this is a kind of automatic stepwise start-up. In combination
with the start-up diagrams below, you can see which supplies
are present at a certain moment. Caution: in case the start-up
in this mode with a faulty FET 7U0X is done, you can destroy
all IC’s supplied by the +1V8 and +1v1, due to overvoltage (12V
on XVX-line). It is recommended to measure first the FET
7U0X or others FET’s on shortcircuit before activating SDM via
the service pads.
The abbreviations “SP” and “MP” in the figures stand for:
•
SP: protection or error detected by the
S
tand-by
P
rocessor.
•
MP: protection or error detected by the MIPS
M
ain
P
rocessor.
