Blau Toronto LED problem ?

[Barry McInnes]

Hi,
Just wondering if this is a common problem. I put the Totonto
in an 89 299TQ in 1999. Worked and looked great until the LED
display started to not display properly. It would miss lines
on the display then work OK, then miss different lines.
Is there a cheap fix anyone has worked out
instead of replacing the LED display
which looks like $120 part ?
I have taken it out and the connectors and parts look OK
on the front section....
