          Dear all,
          The set was in STD-BY.
          I replaced the memory ic 24c32n.
          The set started but when i put it in STD-BY it did not start again.
          The original no was 24c32w. Is there a difference between the 2 ICs.

          Thanks

              When replacing a EEPROM chip, it must be properly programmed for the unit it is being installed in. Replacing the IC with just an "off-the-shelf" EEPROM will not work.
