Back-up Software Upgrade Application
If the default software upgrade application does not start (could
be due to a corrupted boot sector) via the above described
method, try activating the "back-up software upgrade
application".
How to start the "back-up software upgrade application"
manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the "CURSOR DOWN"-button on a Philips TV
remote control while reconnecting the TV to the Mains/AC
Power.
3. The back-up software upgrade application will start.
5.5.3
Stand-by Software Upgrade via USB
In this chassis it is possible to upgrade the Stand-by software
via a USB stick. The method is similar to upgrading the main
software via USB.
Use the following steps:
1. Create a directory "UPGRADES" on the USB stick.
2. Copy the Stand-by software (part of the one-zip file, e.g.
StandbyFactory_88.0.0.0.upg) into this directory.
3. Insert the USB stick into the TV.
4. Start the download application manually (see section "
Manual Software
Upgrade".
5. Select the appropriate file and press the "OK" button to
upgrade.

Content and Usage of the One-Zip Software File
Below the content of the One-Zip file is explained, and
instructions on how and when to use it.
AmbiCpld_Q55XX_x.x.x.x_prod.zip. Contains the
program instruction and software content, needed to
upgrade the ambilight CPLD on the TV550 platform.
BalanceFPGA_Q555X_x.x.x.x_prod.zip. Contains the
BalanceFPGA software in "upg" format.
FUS_Q555X_x.x.x.x_prod.zip. Contains the
"autorun.upg" which is needed to upgrade the TV main
software and the software download application.
PNX5130UPG_Q555X_x.x.x.x_prod.zip. Contains the
PNX5130 software in "upg" format.
StandbySW_Q555X_x.x.x.x_prod.zip. Contains the
StandbyFactory software in "upg" format.
ProcessNVM_Q55XX_x.x.x.x_prod.zip. Default NVM
content. Must be programmed via ComPair or can be
loaded via USB, be aware that all alignments stored in
NVM are overwritten here.

Error Codes
5.6.1
Introduction
Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
Activated (SW) protection.
2
Failing I
C device.
2
General I
C error.
The last five errors, stored in the NVM, are shown in the
Service menu's. This is called the error buffer.
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
An error will be added to the buffer if this error differs from any
error in the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a
deadlock situation. It must always be diagnosable (e.g. error
buffer via OSD or blinking LED or via ComPair).
Service Modes, Error Codes, and Fault Finding
"5.8 Fault Finding and
In case a failure identified by an error code automatically
results in other error codes (cause and effect), only the error
code of the MAIN failure is displayed.
5.6.2
How to Read the Error Buffer
You can read the error buffer in three ways:
On screen via the SAM/SDM/CSM (if you have a picture).
Example:
ERROR: 000 000 000 000 000: No errors detected
ERROR: 013 000 000 000 000: Error code 13 is the
last and only detected error
ERROR: 034 013 000 000 000: Error code 13 was
detected first and error code 34 is the last detected
(newest) error
Via the blinking LED procedure (when you have no
picture). See paragraph
Via ComPair.
5.6.3
Error codes
In this chassis only "layer 2" error codes are available and point
to problems on the SSB. They are triggered by LED blinking
when CSM is activated. Only the following layer 2 errors are
defined:
Table 5-2 Error code table
Layer-2 error code
13
16
27
34
35
5.6.4
How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
By using the CLEAR command in the SAM menu
By using the CLEAR command in the Factory mode:
By using the following key sequence on the remote control
transmitter: "062599" directly followed by the OK button.
If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
5.7
The Blinking LED Procedure
5.7.1
Introduction
The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over
time, an error buffer is available, which is capable of storing the
last five errors that occurred. This is useful if the OSD is not
working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as
many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is "off". Then this sequence is
repeated.
Example (1): error code 4 will result in four times the sequence
LED "on" for 0.25 seconds / LED "off" for 0.25 seconds. After
this sequence, the LED will be "off" for 1.5 seconds. Any RC
command terminates the sequence. Error code LED blinking is
in red color.
Example (2): the content of the error buffer is "12 9 6 0 0" After
entering SDM, the following occurs.
1 long blink of 5 seconds to start the sequence.
12 short blinks followed by a pause of 1.5 seconds.
9 short blinks followed by a pause of 1.5 seconds.
