    I have this 177chzssis that has a good picture on all the channels except 14
    to 18 and 34 to51, I did the solder job but it didn't do any good, what else
    can I do?
    Thank youi
  2. Did you read the voluminous material in the faq?

    I don't understand why no one mentioned the EEPROM. I must be wrong, but I
    thought your symptom was due to the channel preset data getting corrupted.

    Yes....based on the original symptoms corrupted data in the EPROM is
    certainly suspect BUT the grounds connections resoldering in and around the
    OBT (on board tuner) is a very FIRST procedure so if the EPROM is replaced,
    the new one won't get corrupted. A full tuner alignment must be done or if
    good EPROM data cam be downloaded with the Chipper Checker the job will be
    much easier and less time consuming.
    Yes... there is "voluminous" and very good material in the FAQ.

  4. Thanks. I know the soldering must be done first, but I didn't mention that
    because he already did that part.

    Tom Del Rosso:
    I knew that you knew about the soldering being done first... and, like you,
    I am surprised that no one mentioned a corrupted EPROM......
    ......I stated the obvious for the benefit of the OP.
