Eliigh 93 Eldo speedo,tack,digital display stops working!

I have a 93 Eldorado, the problem I have is intermittent, most of the time it will not work. My speedometer and tackometer,all digital readouts including climate controls and radio clock go dark. I'll start the car, sometimes all readouts are working within 5 to 10 miles they stop. Other times I'll be going down the road when it's not working and everything will flash on. Also the ABS light and less often service engine soon comes on. Could this be a ground problem?

What you have is probably a defective Digital Dash Diaplay. Just had mine repaired at Mr Whizard see their web site www.mrwhizard.com flat fee of $189.00 to get mine repaired including shipping both ways.
If you are not mechanically inclined have someone remove unit ship out and
have reinstalled. PS New unit cost $1,790.00 not including removal & installation.
