Had a look this morning and resoldered some of the pins still having issues even the slightest touch on the 8255 and it effects it just wondering if it's worth changing the socket again for a turned pin one.
But Most of the keyboard works most of the time and it has not crashed since so brings me back to the screen pulling any thoughts on what might be causing it something must be breaking down when it gets warm then fine once it cools down.
