Another stupid, I take it that it's a digi dome setup.is the emitter stuck on in.exactly at the correct position sometimes it can be difficult to find behind blacked out glass (not familiar with upc setup) . Last thing Power supplies from.both sender and emitter check /swap and see if it makes a difference. Lastly some tv screens effect ir systems/signals, try move it around a bit ,obvious stuff I know but might help.Originally Posted by John_D
