Any help here guys?

I really need help everyone. Does anyone have any input on this? I see that on eBay there is someone that repairs these issues but I am curious what the process to repair it is since I would be willing to repair it myself.

Good day. I purchased this nav unit about 2 years ago. After about a month of not starting my car (having it on a battery tender) I started it today and as the unit went to turn on it displays nothing on the screen. Just black. I can touch the screen and everything seems to still work but nothing is displayed. Any ideas?
