Is the board in working condition ?
If yes, before you buy a new one, disconnect and remove it.
Get a big painting brush, a dish washing liquid, and give the old board a good wash.
Use plenty of watter to remove all the soap and the inks.
If you have a blower use it to remove the water from the board otherwise wipe it using a soft towel.
Then let the board for two or more days in a warm place to dry completely.
After the drying connect it back and check it's working condition.
This is a way i used to clean boards from inks and dirt at a Domino inkjet Lot & Best before marking machine.
