The bottom line of the LCD screen contains the menu items. When I received it showed the Math menu and the keys A to F took it into different functions. Now all the bottom screen menu items are black and the Keys A to F don't bring up the math menu. The screen display is working because when I go into the EQ Lib the menu shows on the LCD. I have read about 30 pages of the forum but have not found any relevant items.
Any suggestions please?

The [MTH] key will restore the math menu to the F1-F6 keys. You will definitely need to locate a manual to teach yourself the 48GX. Suggest you purchase the MoHPC Document set, which includes all the 48 manuals, plus hundreds of others. Details are here:

If you prefer physical manuals, they are often available for sale on eBay as well, for about $20.00.
