How to
Activate SDM
For this chassis there are two kinds of SDM: an analog SDM and a digital SDM. Tuning will happen according.
# Analog SDM: use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” (or HOME) button.
Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU”(or HOME) button again.
# Digital SDM: use the standard RC-transmitter and key in the code “062593”, directly followed by the “MENU” (or HOME) button.
Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” (or HOME) button again.
# Analog SDM can also be activated by grounding for a moment the solder pad on the SSB, with the indication “SDM” (see Service mode pad). Service mode pad
After activating this mode, “SDM” will appear in the upper right corner of the screen (when a picture is available).

The Blinking LED Procedure
The blinking LED procedure can be split up into
two situations:
# Blinking LED procedure LAYER 1 error. In this case the error is automatically blinked when the TV is put in CSM. This will be only one digit error, namely the one that is referring to the defective board which causes the failure of the TV. This approach will especially be used for home repair and call centres. The aim here is to have service diagnosis from a distance.
# Blinking LED procedure LAYER 2 error. Via this procedure, the contents of the error buffer can be made visible via the front LED. In this case the error contains 2 digits and will be displayed when SDM (hardware pins) is activated. This is especially useful for fault finding and gives more details regarding the failure of the defective board.

Important remark:
For all errors detected by MIPS which are fatal => rebooting of the TV set (reboot starts after LAYER 1 error blinking), one should short the solder paths at start-up from the power OFF state by mains interruption and not via the power button to trigger the SDM via the hardware pins.
When one of the blinking LED procedures is activated, the front LED will show (blink) the contents of the error buffer. Error codes greater then 10 are shown as follows:
1. “n” long blinks (where “n” = 1 to 9) indicating decimal digit
2. A pause of 1.5 s
3. “n” short blinks (where “n”= 1 to 9)
4. A pause of approximately 3 s,
5. When all the error codes are displayed, the sequence finishes with a LED blink of 3 s
6. The sequence starts again.

Example: Error 12 8 6 0 0.
After activation of the SDM, the front LED will show:
1. One long blink of 750 ms (which is an indication of the decimal digit) followed by a pause of 1.5 s
2. Two short blinks of 250 ms followed by a pause of 3 s
3. Eight short blinks followed by a pause of 3 s
4. Six short blinks followed by a pause of 3 s
5. One long blink of 3 s to finish the sequence
6. The sequence starts again.

How to Activate
Activate the SDM
The blinking front LED will show the entire content of the LAYER
2 error buffer, this works in “normal operation” mode or when SDM (via hardware
pins) is activated when the tv set is in protection.
Important remark:
For all errors detected by MIPS which are fatal => rebooting of the TV set (reboot starts after LAYER 1 error blinking), one should short the solder paths at start-up from the power OFF state by mains interruption and not via the power button to trigger the SDM via the hardware pins.
# Transmit the commands “MUTE” - “062500” - “OK” with a normal RC. The complete error buffer is shown. Take notice that it takes some seconds before the blinking LED starts.
# Transmit the commands “MUTE” - “06250x” - “OK” with a normal RC (where “x” is a number between 1 and 5). When x = 1 the last detected error is shown, x = 2 the second last error, etc.... Take notice that it takes some seconds before the blinking LED starts.

SERVICE TIPS
Ambilight
Due to degeneration process of the AmbiLights, there can be a difference in the colour and/or light output of the spare ambilight module in comparison with the originals ones contained in the TV set. Via ComPair the light output can be adjusted.

Audio Amplifier
The Class D-IC 7D10 has a powerpad for cooling. When the IC is replaced it must be ensured that the powerpad is very well pushed to the PWB while the solder is still liquid. This is needed to insure that the cooling is guaranteed, otherwise the Class DIC could break down in short time.

CSM
When CSM is activated and there is a USB stick connected to the TV, the software will dump the complete CSM content to the USB stick. The file (Csm.txt) will be saved in the root of the USB stick. If this mechanism works it can be concluded that a large part of the operating system is already working (MIPS, USB...)

# +1V2-PNX5120 supply voltage (1.26V nominal), stabilized close to PNX5120 chip.
# +3V3 (3.34V nominal, overall 3.3 V for onboard IC’s).
# +5V (5.15V nominal) for USB and Conditional Access Interface and +5V5-TUN for +5V-TUN tuner stabilizer.
# +33VTUN (34V nominal) for analog-only tuners. The linear stabilizers are providing:
# +1V2-STANDBY (out of +3V3-STANDBY), 1.24V nominal.
# +1V8-PNX85XX and +1V8PNX5100 (connected via CFH1), 1.84V nominal.
# +2V5 (WOW FPGA diversity only), 2.5V nominal.
# +5V-TUN (out of +5V5-TUN), 5V nominal.

+3V3-STANDY and +1V2-STANDBY are permanent
voltages. Supply voltages +1V2-PNX85XX and +1V2-PNX5100 are started immediately
when +12V incoming voltage is available (+12V is enabled by STANDBY signal,
active low). Supply voltages +3V3, 2V5, +1V8-PNX5100, +1V8-PNX85XX, +5V and
+5V-TUN are switched-on directly by signal ENABLE-3V3 (active low), provided
that +12V (detected via 7U40 &7U41) is available. +12V is considered OK
(=> DETECT -12V signal becomes high and 12V/3V3 and 12V/5V DC-DC converter
can be started up) if it rises above 10V5 (typical) and doesn’t drop below 10V (typical).
Loudspeakers
Make sure that the volume is set to minimum during disconnecting the speakers in the ON-state of the TV. The audio amplifier can be damaged by disconnecting the speakers during ON-state of the set.
IPB
In case of no picture when CSM-test pattern from PNX51XX is activated and backlight doesn’t light up, it’s recommended first to check the inverter on the IPB + wiring (LAYER 2 Tuner
Attention: In case the tuner is replaced, always check the tuner options.
PCI bus.
The splash screen image is not distributed via the regular YUV signal path from the PNX8543 to the PNX51XX, but loaded one time via the PCI bus.Once the splash screen image is loaded into the PNX51XX, it will be continuously generated by the PNX51XX until the first incoming video disables the splash screen.So when teletext and/or general UI is available, but no splash screen (option “ON”) is visible during start-up, check the PCI bus as possible root cause.
