SmartCraft gauges issues. P IV with 200 opti

I am having problems with my SmatCraft gauges in my P IV 2005 model with 200 Opti. The gauges are working but the LCD screen that shows the vitals on motor and other info are very milky or faded that you can barely see the info if at all unless you use a flash lite or get just the right angle in sun. Has any one had this problem. Its on speedo and tach both. Again all is working just cant read it without manipulating. Can these be repaired? Hate to replace them at costs Ive seen but hate to take risks of not being able to see. If any one can help please do. Thanks.
