John. i'm sure others with more experience than me will contribute, but AFAIK the 'fix' for this sort of fault is panel replacement. working on individual 'rows and columns' is not something i've ever heard of.... -B |

Yup. The rows and columns are driven by chips that are bonded to a flexible PCB that connects to the LCD itself. The chips cannot be replaced. |

This problem can be caused by dirty or oxidized contacts.
LCDs are often "attached" to the PC board with a conductive rubber strip (not solder). Lifting the LCD and cleaning the board often fixes the problem. |

The chips can be and are replaced as a module including the flexible PCB, there are companies out there who will do this. As to the economics of replacing them on a TV or monitor... -- Clint Sharp |

The panels I've looked at lately all have chips bonded to the LCD substrate. The are not packaged but are raw die located along the vertical and horizontal edges. Only the original manufacturer of the panel might be able to replace them, but I'm not even sure they could. |
