Display screen issues

Hello all! I’m new to this Honda forum. I’m a big Honda fan. I own a couple… I just picked up a 2004 Honda Rancher 350 ES 4×4 for my boys. It originally showed just under 1600 miles on it. It now shows 999999 for the odo and 999999 for the hours. It did have a dead battery and sat for a little while with the dead bat. Any recommendations on how to fix it? Also switched over to km/h. I attached a pic. I’ve checked the fuses, checked and replaced the battery, held down the odo button while turning the key on several times. Do I need a new display screen or is there another problem? Thanks for the help!!
