Guys - I came back from my vacation and the batteries in my krp 500m remote control had leaked and now I can't get some buttons to work on the remote control. Input 4 won't work and that's where I connect my pc to watch movies but most importantly I can't get into any of the menus because the enter button won't work either. I took the batteries out, cleaned the remote from the battery area and put in new batteries but still doesn't work. Any ideas? How do I open this thing up? Thanks!!
