I want to use stick-on emitters with my JVC AV-56P585 (or AV-56P575, not sure which model it is) 56" rear projection unit, so I can control the TV using my computer, but I am unable to locate the IR window. When I scan the entire surface of the TV by holding my remote about .5" away from the surface, the remote will only work when I am holding it front of the glass. I tried the speaker grill, every other spot, but no luck. Is the IR receiver hidden behind the actual glass (which would mean I can't use the stick-on emitters)? Thanks!
