5.
(measured via I2C), the Receiver box goes into protection
mode.
5.6.2
OTC Input Protections
If a protection is detected at an input of the OTC, all protection
inputs of the OTC will be scanned every 200 milliseconds five
times. If the protection on one of the inputs is still activated after
1 second, then the set will go into protection mode.
Possible protections:
•
8V6 and 5V2 protection. The presence of the 8V6 and
5V2 is sensed by the OTC. If the 8V6 and/or 5V2 are/is not
present, then an error code is stored in the error buffer.

Repair tips
5.7.1
How to Deal with a "TV configuration" Situation
It is not easy to access the CSM menu without the
accompanying plasma monitor. Therefore, it is best to retrieve
this information while you still have the complete configuration.
Depending on the fault, the problem may be easily solved.
However, if this is not the case, some of the data recorded
could assist you in the repair.
5.7.2
How to Deal with a "Receiver Box Only" Situation
Without the accompanying plasma monitor, the Receiver box
will go into Standby mode after a few seconds (this monitor
detection is designed to prevent Philips Receiver boxes from
being used with other brands of monitors).
This detection can be overridden in the following way (to use,
for example, a PC monitor):
•
Enter the SAM-mode via ComPair (using the "align" key of
the DST simulation mode), or through the HW intervention
of connector 0356 on the SSP (pins 2 and 3). The set will
now operate in SDM. Then short pins 1 and 2 to enter SAM.
•
Via navigation in the SAM menu and selecting, you must
follow the this route: "Service Options" - "Miscellaneous" -
"Stand-alone".
•
Toggle "No" to "Yes" and store this change (this means that
a bit is changed in the NVM).
•
Now the Receiver box can operate with any monitor (for
example, a PC monitor).
•
The Service technician can now perform the diagnosis and
repair (the CSM menu can also be accessed now).
•
When the problem is solved, the Stand-alone option bit
should be reset to "No", to return the set to the original
setting.
5.7.3
Miscellaneous Tips/Remarks
•
Sometimes, when there is an NVM related error/problem
and the set does not want to start up, it can be helpful to
start the set without the NVM (IC7008 on the IC holder on
the SSP). You can see OSD on the monitor, for a short
time, so you can conclude that much of the circuitry is
working fine.
•
If an empty EAROM (permanent memory) is detected, all
settings are set to pre-programmed default (standard)
values.
•
To overrule the childlock PIN code, use code "0711".
•
When the user settings related to optimal picture and
sound performance are in doubt, one can restore the
default factory settings via: "Settings" - “General” - "Reset
AV settings", and pressing the "OK" key on the remote
control transmitter. This may help correct an incorrect user
setting faster, since the starting point is more clearly
defined (for example, the set will leave the factory with
"DNR" on medium, "Dynamic Contrast" on medium, and
"Sharpness" on 4, etc)..
