JVC R-X500 part of Display Dark


Hello I just bought this Receiver recently and the display the section where the volume and the different inputs are the display it is dark only in that 3 inch or so section. Anyone know what this could be . It's all new to me and I'd really appreciate it. I really try to keep my audio on top top condition and little things like this drives me crazy til it's fixed. Thank you very much
