If it's not under warranty, I would advise taking the face plate apart and checking for burned spots on the board and using compressed air to remove anything that is conductive that may cause a short in the face plate. The face plate should be really easy to take apart.

My Alpine CDE 7872 faceplate goes blank intermittently, the unit still functions, just can't see what station you are on, what track, volume, etc...


is the faceplate detachable? if so remove it and clean the metal contacts on both the din unit itself and the faceplate with rubbing alcohol on a cotton swab or Q tip.

if it is not a detachable face, then i would say an internal solder joint is starting to come loose, that is an older alpine model number after all.

Hi there,
If this model has a detachable faceplate,
Remove the faceplate and clean down the contacts with metho and a cotton bud. 
Over time usually corrosion and dirt etc builds up on these terminals making them loose cotact when you touch the faceplate.
This is the most commonly known problem alpine units.
Other common problems is the power supply failing /amplifier.
Hope this helps you out
Cheers
Steve
