Some of the LCD elements (small squares) on the display are failing to
light. If I push on the end of the ribbon cable where it connects to the
edge of the display driver PC board, the problem elements will start
working until I remove the pressure. This leads me to think that the
ribbon cable's connection pads are failing. Is there any way to repair
the PC connection pads for each conductor of the ribbon cable on the
edge of the board? There isn't any hardware connector for the ribbon
cable on the board. It connects directly to the pads on the edge.

BTW- This is the second time the display has failed in the same way. I
replaced the entire display assembly (LCD and driver board) about two
years ago. Cost about $90. The replacement worked fine until recently.
Since the home is not occupied in the winter, the heat is turned off.
The temperature can get down to well below freezing for days or weeks.
Could this be why the display has failed twice?

Thanks
