    Dell Ultrasharp 30" LCD Monitor ghosting...

    Looking at maybe purchasing a Dell 30 monitor, but apparently after a move it started ghosting. Is this an easily repairable problem? I am still pretty new at this.
    Thanks

    This will be a tab bond issue.

    This is repairable, but difficult; it depends on your level of skill.

    See this video: different problem, but same root cause (bad tab bond)

    I wouldn't pay much, maximum £15 (around $25) because of the risk of damaging the panel.

      Thanks for the response. Could you elaborate what is involved with the fix?

        As tom says, it does seem to me like a tape carrier bonding issue. Try getting some freeze spray and spray along each edge carefully whilst the screen is on to see if any changes occur at all. These ribbon tapes are stuck onto the panel using Anisotropic Conductive Film:

        Messing about with the tape carriers is VERY risky thing to do and can render your panel completely worthless so I might buy a replacement TCON board from buychina.com to rule that out (but in all honesty it's probably not worth it - even for such an expensive display). Either way this problem is either the TCON or the connection from the TCON to the panel itself. There could be an outside chance that the power to the TCON board is at fault but this can be ruled out with a multimeter.

          I will steer away from this one. Thanks.
