Lcd Displays - Trip Computer

[Guest Bobc]

The LCD displays on my Mondeo 2002 flash, flicker or blank out when hot. THis occurs on sunny days when the car has been parked but recovers once the air con brings the inside temp down to comfort level. I have also noticed the display flashes or fades out on a long run - I guess when internally hot due to being powered on for some time.

I have mentioned this to Ford's Service but they tell me they can't do anything unless they see the problem. I'm obviously a compulsive liar as far as Ford is concerned! The problem is relying on the weather to be bright, hot and sunny whilst the car is parked outside a Ford Service dept for long enough to cause the display to flash. Driving there gives sufficient cooling for the problem to disappear - unless I put up with the discomfort.

Has anybody else out there seen a similar problem. Should I cover the dash with a wet cloth every time I park or should I emmigrate to some place where the sun rarely shines?

Apart from this I think my Mondeo is a great car - but then I am a compulsive liar as Ford believes..... Bobc :unsure:

i have the same problem on a 96 ghia model. several segments disappear when the weather is hot, eg the sun is out.

 

I have been informed that the display consists of two pieces of glass sandwiched together with liquid in the segment and electrical contacts at various positions. The sun heats the glass which expands. This in in turn cuses the liquid not to make proper contact with the eletrical contacts. If you gently run your finger over the glass. NOT TO HARD you will notice the display appear, but will fade away.

 

You could try covering up the display, put a cloth or foil sun blind over dash, although if its not working properly now it never will. it might work once the weather cools down.
