SERVICE DEFAULT MODE {SDM}
Service Default
Mode (SDM) and Service Alignment Mode (SAM) offer several features for the
service technician, while the Customer Service Mode (CSM) is used for
communication between a Customer Helpdesk and a customer.
There is also
the option of using ComPair, a hardware interface between a computer (see
requirements below) and the TV chassis. It offers the ability of structured
troubleshooting, test pattern generation, error code reading, software version
readout, and software upgrading.
Minimum requirements for ComPair: a Pentium processor,
Windows 95/98, and a CD-ROM drive.
Remark: as the Hotel Mode is a User Mode, rather than a Service
Mode.
SDM: PURPOSE
To create a
pre-defined setting, to get the same measurement results as given in this
manual.
To override SW
protections (only applicable for protections detected by stand-by processor)
and make the TV start up to the step just before protection (a sort of
automatic step-wise start up).
To start the
blinking LED procedure (not valid in protection mode).

- Tuning frequency 61.25 MHz for NTSC: The TV shall tune to physical channel 3 only if channel 3 is an analog channel or if there is no channel 3 installed in the channel map. If there is a digital channel installed in channel 3, then the frequency to which the set will tune, would be as specified in the channel map and could be different from the one corresponding to the physical channel 3.
- All picture settings at 50% (brightness, color, contrast).
- All sound settings at 50%, except volume at 25%.
- All service-unfriendly modes (if present) are disabled, like: { (Sleep) timer. Child/parental lock. Picture mute (blue mute or black mute). Automatic volume levelling (AVL). Auto switch "OFF" (when no video signal was received for 10 minutes). Skip/blank of non-favorite pre-sets. Smart modes. Auto store of personal presets. Auto user menu time-out.}
TO ACTIVATE SDM
Use one of the
following methods:
- Use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” button.
Note: It is possible that, together with the SDM, the
main menu will appear. To switch it "OFF", push the “MENU” button
again.
- Short for a moment the two solder pads [1] on the SSB, with the indication “SDM”. They are located on top of the SSB. Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor. See figure “SDM and SPI service pads”.
After activating
this mode, “SDM” will appear in the upper right corner of the screen (if you
have picture).
TO NAVIGATE: press the “MENU”
button on the RC transmitter, the set will toggle between the SDM and the
normal user menu (with the SDM mode still active in the background).
TO EXIT SDM
Use one of the
following methods:
- Switch the set to STAND-BY via the RC transmitter.
- Via a standard customer RC transmitter: key in “00”- sequence.
