Symptom:
(XXXX) If the need should arise that a circuit board needs to be replaced, It might contain an EEPROM. If
the EEPROM data is not written into the EEPROM of the replacement board all the service or customer
adjustments will be lost.
Example: Convergence adjustments. This will then require additional time to re-converge a projection TV.
DATA information retrieval is especially important for the models covered in the SAYS program, since
the turn around time is of the utmost importance.
Solution: Please refer to the updated General Bulletin 31 for the connection and
switching information. This can be found under model GENTVP.
