My Sony VW60 IR seems collide with my other equipment such as my Yamaha receiver, Pioneer Kuro plasma! eg, when I turn on/off my plasma or receiver it will also trigger the Sony PJ to turn on/off (not always from the receiver but everytime from the plasma). Is there a way to solve this issue? My pj has been keep turning on/off many times a day!

More details please: what remotes(s)? Universal remotes? IR extenders/distribution? IR to RF? Where is plasma? where is PJ? Where is receiver?.....

Just the remote come with the equipments. Plasma is placed behind the motorized drop down screen and the receiver is placed under the plasma. The PJ is placed 15ft away from the plasma and is ceiling mount. No matter on what direction when I turn on my plasma(with its remote), it will trigger the Sony power button and sometimes when I turn on the receiver(with its remote), it will also trigger the power.

Hmm, what happens if you turn on the plasma manually - not with the remote? What happens if you cover the plasma IR receiver with your hand and use the plasma remote on/off (point at PJ)... Plasmas have been known to output IR...

manually turn on/off plasma or receiver will not trigger the projector. But never try to cover the IR receiver of the plasma.
