I just bought a DGX 520 keyboard. The first time

i just bought a DGX 520 keyboard. The first time I plugged it in at home I noticed I could not read the display box that tells me what mode I am in. It's sort of like a cell phone picture - if I look at it from odd angles I can make out what it says. But if I try to read it from where I sit to play I cannot read it at all. This is not how it appeared in the store. I have gone to troubleshooting in the manual but there is nothing that addresses this problem. Thanks for your help.Colleen Whiteford
