5.8.12 SSB Replacement
Follow the instructions in the flowchart in case a SSB has to be
exchanged. See table 5-3
SSB replacement instructions.
For a more general overview of steps to follow, refer to figure
5-11
SSB replacement flowchart.
Table 5-3 SSB replacement instructions
Step # Action to do Advise / Attention points / Remarks
1 Ensure ESD protection by using a wristband 2 If SSB is still functional: Go via SAM to “upload to USB” and copy Personal
settings - Option codes - Alignments (Presets) - Set Identification.
Advice: because of differences in memory al location, it is adv ised to up grade
main SW before copying data from existing SSB. Copy of Preset list is
possible from normal user interface.
Upload to USB: a directory “repair” will be created on the USB, and all data will be copied in this
directory. In case of issues by copying the program map table, it is advised to reinstall the
programs from Virgin mode instead of using copy via USB.
3 Disconnect set from mains and from antenna. Safety and ESD!
4 Open the set and disconnect LVDS flat cable. Disconnect other cables /
connections.
Always take care for ESD! Be extra careful when removing connectors!
5 Dismount the (defective) SSB from the set. Do not damage SSB copper tracks with your tools! Do not scratch bottom of SSB (be very car eful
by moving SSB over SSB supports). See Figure 5-9 and Figure 5-10.
6 Place new SSB in the set, and fixate/mount carefully. D o not damage SSB copper tracks with your tools! Do not scratch bottom of SSB (be very ca reful
by moving SSB over SSB supports). See Figure 5-9 and Figure 5-10.
7 Connect PSU and other connectors. Insert the optional WiFi module. Make sure that the connectors are correctly plugged-in and locked (click). Special attention for the
optional WiFi module: a defective WiFi module can give re boots or no start- up of the SSB . In this
case do a trial without WiFi module.
8 Connect LVDS connector(s). Be very careful: wrong or bad connection can damage the TCON part on the SSB and damage
the LCD display. Check if flat cables are fitted correctly before closing the connector lock.
9 Connect set to mains and switch TV “On”. Check start-up of the set, backlight switching “On”.
10 If the set does not start (or reboots) check:
- The connectors from the power supply,
- The power supply cable and connec tion pins,
- LVDS cable connection.
Power supply connector must “snap” into the socket.
11 Before programming the new SSB, upgrade to latest software. If set is starting
up in software upgrade mode, then first install new software via software
Upgrade Menu or via the autorun.upg file.
Some SSB’s will start-up in software upgrade mode, and software needs to be installed before you
can program the Display Option codes. It’s adviced to use an autorun.upg file for software
upgrade, this in case you have no OSD on the screen.
12 If set is starting up without picture or menu (OSD), first program the correct
Display Option codes.
Use blind service mode “062598” + “Home” button, directly followed by the
Display Option code (3 digits). Set will switch to Standby after Display Option code is entered.
13 Go to SAM and program “Set type” and “Serial number”. This is possible via
the NVM editor and virtual keyboard. In case personal settings were
recovered from the defective SSB, you can use an “Upload from USB”.
Programming “Set type” and “Serial number” is mandatory to have all functionality of the set, like
DLNA, Net TV… For certain sets you may need to use ComPair for this.
14 Check if option codes are correct, and keys are present. SSBs w ith integrated
TCON needs TCON alignment in SAM.
Validity of HDCP, CI+, Marlin, and WDRM keys can be checked via ComPair.
15 Update to latest software (Standby and main software). This step is necessary
to make sure that the (optional) 200Hz T-CON board has the latest software.
Even when the SSB already has the latest softwar e, it is manda tory to upgrade a gain the softwar e
to update the 200 Hz T-CON part. At the end of the main software update process, a dedicated
software is loaded, from the main processor via the LVDS connection, to upgrade the
200 Hz T-CON part. For certain LCD displays, a dedicated Display software patch (autoscript) is
available. See General Service info GSC_85590.
16 Once the set is playing, check cable connection between PSU and SSB, by
moving the cable if there are no bad connections.
Check the two power connectors on 1M90. Bad co ntact or ba d connectio n here can give rebo ots.
17 Fill in the Electronic DDF (Defect Description Form): Fault symptom, TV type
and TV serial number.
It is mandatory to fill in the E-DDF form (see the “At Your Service” web portal).
