I have a dead diagonal row of keys on my Toshiba Tecra laptop keyboard. It is the 4 r f v keys.
I just installed a new keyboard and the problem persists to my dismay!!
So if it isn’t the keyboard what can I do to fix it?

First of all, try cleaning pins inside the keyboard connector on the system board. Spray pins with a connector cleaning solution. You can find this solution in a local electronic store. It’s possible that some pins oxidized and the keyboard cable is not making good connection with the system board. I use ProGold connector enhancer.

If cleaning the connector doesn’t help, most likely there is a problem with the keyboard controller on the system board. If that’s the case, you’ll have to replace the system board.
