Chevrolet Repair: No display, circut board, dash unit

Question
My electronic gauge display just quit working one day.  I checked the fuses and all are still good.  I do have a brake/ABS lights on the display, still on though.  I can't see the Speed, temp, tach, fuel or anything.  Do you have any suggestions?   Thank you!

Answer
Hi John... check the circut board they are known to go bad...try putting a known good dash unit in and see if it will work, that will tell you if you have a wiring problem...make sure the fuse for the gages is good as well...these electronic dashes can drive you nuts... hope this helps
