After the default values are downloaded, it is possible to start-up and to start aligning the TV set. To initiate a forced default download the following action has to be performed: 1. Switch “off” the TV set with the mains cord disconnected from the wall outlet (it does not matter if this is from "Standby" or "Off" situation). 2. Short-circuit the SDM jumpers on the SSB (keep short circuited). 3. Press “P+” or “CH+” on the local keyboard (and keep it pressed). 4. Reconnect the mains supply to the wall outlet. 5. Release the “P+” or “CH+” when the set is “on” or blue LED is blinking. When the downloading has completed successfully, the set should be into Stand-by, i.e. red LED on. Alternative method (1): 1. Go to SAM. 2. Select NVM Editor. 3. Select ADR (address) to 1 (dec). 4. Change the VAL (value) to 170 (dec). 5. Store the value. 6. Do a hard reset to make sure new default values took place. Alternative method (2): It is also possible to upload the default values to the NVM with ComPair in case the SW is changed, the NVM is replaced with a new (empty) one, or when the NVM content is corrupted. After replacing an EEPROM (or with a defective/no EEPROM), default settings should be used to enable the set to start-up and allow the Service Default Mode and Service Alignment Mode to be accessed. 5.7.3 Start-up/Shut-down Flowcharts On the next pages you will find start-up and shut-down flowcharts, which might be helpful during fault finding. Please note that some events are only related to LCD sets, and therefore not applicable to this PDP chassis.
