This can be caused by these defects:
1 - the connections to the plasma panel are loose. To fix that you must open the case of the tv and reseat all connectors to the panel.
2 - the memory of the image processor(or in rarer cases th processor itself) has failed so you end up with image corruption - the image board must be replaced; this will cost you around $150, without labor. By your description this appears to be your case.
3 - the plasma panel itself has suffered a damage in the pixel lines connections - this cannot be fixed, terminal, the tv should be used as is or junked.

    Dear,

    Thank you for your solution proposition.The lines apprear in all connection type and even when all cables are unplugged.

    Is this something that happens frequently with Plasma screen? or with Panasonic?

    Is there a better brand/solution for a new tv?

    Since the defect is present even without any cables connected then the defect is located in the plasma screen - this is unfixable.
    Highly uncommon on modern plasma's, much more common on LCD's. But it's a common way to go on older plasma panels like yours. Any modern plasma tv has virtually eliminated the problem so you can buy one without a problem.
    Personally i would avoid Samsungs (too may unrelated reliability problems) but everyone else will be just fine. Just go into a shop and look for the one with the best image - and try them, in shop they are usually pushed to their absolute maximum, no room for improvement afterwards.
    My personal best, the one for i save all my money - Panasonic Viera TC-P50VT25

Thin blue vertical line left of middle on screen


Sounds like a faulty Plasma Display Panel.

Contact Panasonic and find out if it is still covered under warranty.
