1. Adjust the antenna for better reception.
2. Some electronic euuipment can create electrical noise, which can interfere with TV reception. So move TV away from other electronic equipment.

The black bar you had mentioned in your title points to a pulse on the jungle Ic. The black bar is prob intermittent and does not happen all the time. You can replace the Jungle Ic and it will most likely clear up a lot of your prob this is IC301 on the A board and the part number is 8-752-095-96 personally I would replace the A board to make sure the whole prob is taken care of this is part number A-1298-841-A it would be more apt to fix all of your problems the A board will run you about 175 dollars so it might not be worth it. The Jungle Ic on the other hand is about 25 dollars so its worth a shot.

Hi,

It may not be the TV but rather interference, have you checked your cable connection?

One way to verify if it is the TV or your cable is to install an old VCR using its RF OUT connected to the ANT/Cable IN of your TV. Play a known good video tape and set TV to either Ch. 3 or 4. If problems persist, it is the TV (possibly tuner) if not, it is your cable connection.

Hope this be of initial help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

Hi,

If you observe horizontal lines then the problem is with Vertical amplifier unit and needs to be replaced.And you also said that the picture is Ghost then the problem is with STK IC'S even that needs replacement and you have to call a technician to get it done.
However you can try this method once, Do the reset test Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.

Goodluck,
Please don't forget to rate me as fixya..

    So finally i just want o say that since you don't have a problem with dvd then It is a malfunction of the vertical blanking circutry which is
    supposed to blank out while retracing to keep the horizontal retrace
    from showing during that period. It is a function of the 'jungle chip',
    one of the main processors in the tv. It requires a tech to take
    measurements to identify the correct malfunction as there are many
    parts associated with this process.

    I just found out that the problem is not with your STK IC"s..
    It is malfunction of vertical blanking circutry..
