    I have a Panasonic 20" CT2006se TV that has a strange problem. When
    it is turned on picture and sound are fine. After 5-7 seconds the
    picture goes blank, sound still works. Anytime I change channel,
    change sound, or any other button on the remote or front panel
    buttons, the picture comes back for 5-7 seconds and then disappears.

    When I push the "Setup" button to change settings, the picture stays
    on as long as the Setup Overlay is on the screen. All Picture,
    Timer,Setup settings are fine, the "V chip" function is off. If this
    was a computer, I would say it it a BIOS corruption issue. Is it
    possible that the Setup function (which is Firmware) can be reset or

    Thanks for all info,
  2. The micro is bad. Try unsoldering pin 33 and see if it stays on.
