Bus ignore mode
If an error occurs in the IIC bus system which makes the TV go into stand by every
time it is attempted to be switched on, it is possible to switch on the TV in such a
way that the error is ignored:
- The TV must be in stand by for at least 5 seconds.
- Short-circuit the socket, P84 coordinate 4L on the AV Switch PCB14 for a minimum
of 0.5 seconds.
- Remove the short-circuit.
- Press TV. The TV will now start up in bus ignore mode with service menu if possible.
IMPORTANT! If the TV is started up in ignore mode it may result in further damage
to the TV.
- Exit ignore mode. Turn off the TV.
