Display problems S60 D5 2001

[gardacus]

Hi all

Since a month I have the following problem with my entire gauge and board computer display.

The first 20-30 minutes of the drive my displays go completely berserk: All possible characters in the LCD displays show, the board computer only shows a line of ------------- and the gauges all show 0. So fuel, RPM, speed and temperature.

This seems to disappear after about 20-30 minutes and then everything is back to normal, except for the board computer... which keeps showing dashes.

I went to 2 different dealers, but they cannot find the problem.
I suspect myself a problem with the print board... Either a connection or a cable breach.

Does anyone have a wiring schedule for the print board of the display... or the cabling to the display?

I am constantly speeding when all my gauges are at zero, so any help would be welcome.

Many thanks

Mike
