    Why?

    Chip? Battery? Remote?

    Why?

    Why doesn't anyone know? I've asked this last year and no one ever
    answers!

    Why?

    Do you have the set plugged in to an outlet that the power is being switched
    off? Some users plug their set in to an outlet that they have a light
    switch on, and are killing the power to the set as well. Most of these sets
    use a volatile memory for the simple things such as channel set-up. The
    factory set-up is written to an EEPROM that is in part of the main uPC.

    If your set is connected to a proper AC outlet that has constant
    un-interrupted power, then there may be a fault with the standby supply, or
    there is a defect in the circuit area for the uPC.

    I plug in my TV directly into the wall electric socket. I don't
    experience the power going out.

    So this means my TV's standby power supply is bad?

    But you see, my TV won't remember channels EVEN when it's left On
    after I supposedly Autoprogram, Add or Delete channels. I see the TV
    autoprogramming through the channels (scanning the channels) and I see
    the green Add and Delete symbols when I push add or delete. But even
    without turning off the TV, I still CAN'T scroll to the channels that
    I supposedly just added. It's like it pretended to add/delete channels
    but it didn't do anything. Like the memory is locked (locked to what I
    set 2 years ago) somehow.

    Other than that, my TV works perfectly with my remote. I can manually
    type in channels and push Enter and it goes to the channel. I just
    can't get my TV to remember channels that it currently doesn't have
    saved in the memory.

    I always have to use the manual channel entry method which makes
    channel surfing very slow.

    Do you think this is cheap to fix/diagnose at TV repair shop? My last
    Trinitron cost $100 to replace the power supply but in that case my TV
    was really dead (wouldn't turn on).
