    Hi

    I have a start-up problem with my TDS3014B. It start backlight an
    actually the start screen is Ok. It pulses all front leds for a littl
    bit and then the 1KHz/5V square wave becomes available. Start scree
    remains without change and there is no any diagnostic message
    Troubleshooting chart doesn't cover this situation since it only i
    useful when diagnostic message apply. It seems to be a softwar
    problem rather than electronic problem.
    Service from Tek is expensive. I heard about a key sequence to initiat
    to factory settings.

    I will aprreciate if somebody have an idea to solve this...

    Regards

    You might get a reply if you started out by saying what it is that you
    want to discuss, such as a tv or monitor or test equipment. Just
    seeing tds--- doesn't give me a clue what it is you want.

    Hi Bob


    You're right about my title was too short. Perhaps, I was a little bi
    frustrated since all night searching for help so I probably did mis
    what I was trying to say.

    In fact TDS doesn't say too much but I was trying to discuss abou
    Tektronix Oscilloscope. May you're familiar with that instrument sinc
    your appointment was so precise.

    Anyway. I apologize and thank you for your help. I now have edited m
    first topic description.

    Regards

    Well, when I saw TDS3014 I immediately knew it was a Tek scope. Don't most
    people? (c;

    I thought it might have been a time domain spectrometer.

  6. Go for www.tektronix.com, left click "manuals", go for your Type
    (3014b), check the offered selection.

    I think you mean the document: "TDS3000 and TDS3000B Instructions
    Memory Erasure and Nonvolatile Memory Parts List P/N 071172200".

    It resets the flash memory, but leaves the factory constants for
    calibration, etc intact.

    BTW: You may need to set up a download account, it is free of charge,
    so simply go for it.

    The service manual is also around there, but do not expect circuit
    drawings within: TDS 3xxx is serviced on module exchange basis only.

    Hi Andreas

    Thanks for your time to check this site.

    I tried to use this tek sequence before, but actually the oscilloscop
    has locked up.
    Tek people says there is no a "hold down key while..." sequence. The
    say this is just for microproccessor based oscilloscopes. I'm not sur
    which kind is this, but I would think there should be any escap
    sequence as:

    \"MY 11402 HAS LOCKED UP. I HAVE TRIED POWERING IT OFF, THEN ON AGAI
    WITH NO SUCCESS. HOW CAN I RESOLVE PROBLEM? \"[/B]
    AT:
    http://tinyurl.com/2whl5f



    I CANNOT ACCESS ANY SCREEN MENU OR RESPONSE BUT POWER UP SCREEN. ABOU
    7 SECONDS AFTER POWER ON, FRONT LEDS FLASHES ONCE AND THEN SQUARE WAV
    OUTPUT FOR PROBE COMPENSATION BECOMES AVAILABLE BUT NOTHING ELS
    HAPPENS. SCREEN REMAINS AS THE INITIAL POWER UP SCREEN WITH THE TOO
    ABOUT \"DIGITAL PHOSPHOR OSCILLOSCOPE... TEKTRONIX\" AND NOTHING ELSE.

    I HAVE TRIED UPLOADING THE FIRMWARE THRU FLOPPIE DISK BUT DISK DRIV
    DOESN'T WORK AT ALL.

    I TRIED TO USE THE TROUBLESHOOTING CHART BUT IT DOESN'T SEEM TO B
    ENOUGH FOR THIS CASE. IN FACT WHEN TROUBLESHOOTING PROCEDURE SAYS:

    Q: *\"DOES THE SCOPE DISPLAY THE POWER-UP SCREEN?\
    A: Yes/
    Q: "Does the Scope pass all the Diagnostics?"*
    A: No, but it doesn't display any result message. It freezes at th
    Power-up Screen.
    CONTINUE WITH: \"PERFORM MODULE INSULATION TROUBLESHOOTING PROCEDURE\
    ...and here is why I'm saying it is not enough....
    Next: *"Module Insulation Troubleshooting procedure"*
    NOTE:\"THIS PROCEDURE ASSUMES THAT THE OSCILLOSCOPE DISPLAYS POWER-U
    DIAGNOSTIC MESSAGES\
    Q: *"Does the power-up screen report any errors?"*
    A: No, but it doesn't display any result message
    *Result: "Oscilloscope is operating Ok"* Which is false.

    Are you familiar with this instrument?...
    I don't know other people familiar with...
    I never had similar trouble before with any fluke firmwerable or Te
    TDS754D scopes.

    Regards
