95 Cirrus w/ intermittent speedometer

1995 Cirrus with an intermittent speedometer. At the time the speedo is
lying on zero, there is a box that encircles each of the gear numbers /
letters on the front panel.

P R N D 2 1 all have a solid box around each .... like it was in each of
the gears simultaneously. Shutting the engine off and restarting will
restore normal operation.

Any ideas? This is weird.

Thanks all.

 

cluster has a burn't circuit board

 

Good guess, but it turned out to be faulty TCM and 12 Volt TCM relay.

All better now.
