This can be caused by either the FFC (Flat Flexible Connector) from the address board to the screen. There are a few of these connectors so you need to judge from the position on the screen as to which one is at fault. You need then to dismantle the main board to gain access & then remove the heatsink running along the bottom to gain access to the board, you need to carefully disconnect the cable & try to clean the contacts, then re-assemble. This can sometimes cure the problem, but I have had this fault a few times & have only been sucessfully a couple of times because inevitably the fault is internally within the screen itself & cannot be fixed. The only solution then is to replace the screen which can be costly I'm afraid.

There is a vertical red line that runs down the screen on our Sanyo TV. It is just a thin line but it is annoying because you know it is there. Any suggestions?


thin lines are associated with the connection of the pixels on the screen in the grid. If its under warranty get it fixed before expiry as its not a cheap fix.
Red lines are not convergence problems they are component problems so you cant adjust it out

Vertical lines in my laptop screen


Try connecting an external monitor to the Dell Inspiron 9300 and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.
Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.
