Manual Start of the Main Software Upgrade Application
Normally, the software upgrading procedure will start
automatically, when a memory device with the correct software
is inserted, but in case this does not work, it is possible to force
the TV into the software upgrade application. To do so:
•
Disconnect the TV from the Mains/AC Power.
•
Press the “OK” button on a Philips DVD RC-6 remote
control (it is also possible to use the TV remote in "DVD"
mode when available).
•
Keep the “OK” button pressed while connecting the TV to
the Mains/AC Power.
•
The software upgrade application will start.
•
When a memory device with upgrade software is
connected, the upgrade process will start.
5.8.4
Stand-by Software Upgrade
It will be possible to upgrade the Stand-by software via a PC
and the ComPair interface. Check paragraph "ComPair" on
how to connect the interface. To upgrade the Stand-by
software, use the following steps:
1.
Disconnect the TV from the Mains/AC Power.
2.
Short circuit the SPI pins [2] on the SSB. They are located
outside the shielding (see figure “SDM and SPI service
pads” earlier in this chapter).
3.
Keep the SPI pins shorted while connecting the TV to the
Mains/AC Power.
4.
Release the short circuit after approx. two seconds.
5.
Start up HyperTerminal (can be found in every Windows
application via Programs -> Accessories ->
Communications -> HyperTerminal. Use the following
settings:
–
COM1
–
Bits per second = 38400
–
Data bits = 8
–
Parity = none
–
Stop bits = 1
–
Flow control = Xon / Xoff.
6.
Press “Shift U” on your PC keyboard. You should now see
the following info:
–
PNX2015 Loader V1.0
–

–
DEVID=0x05
–

–
MCSUM=0x0000

7.
If you do not see the above info, restart the above
procedure, and check your HyperTerminal settings and the
connections between PC and TV.
8.
Via “Transfer” -> “Send text file ...”, you can send the
proper upgrade file to the TV (e.g.*.hex). This file will be
distributed via the Service Organization.
9.
After successful programming, you must see the following
info (this can take several minutes):
–
DCSUM=0xECB3
–
:Ok
–
MCSUM=0xECB3
–

10. If you do not see this info, restart the complete procedure.
11. Close HyperTerminal.
12. Disconnect and connect Mains/AC Power again.
