I am trying to set up an IR repeater with a Samsung DLP rear projection TV. I know the receiver is supposed to be behind the screen. I have tried moving the emittor everywhere on the screen but it apparently is unable to activate the receiver. I remember reading a post about opening up the TV and putting the emittor directly on the receiver? How exactly do you do this? Any help would be appreciated! Thanks

IIRC the IR sensor is in the round power button on the front of the Samsung DLPs....

I tried that also without any effect. I also used the remote and it seems to work when you point it at the screen but not when you point it at the round power button?

Your test of where you have to have the remote to get responses shows that the sensor is behind the screen. That puts it much further from an external IR emitter than normal. Maybe an emitter on the front of the screen needs to put out way more IR than normal. Plus, maybe that IR emitter isn't working.

Test it with another component to be sure it emits IR. If it does, it could be that the amount it puts out will not work further than a couple of inches from the sensor, so a sensor behind the screen would not see it.

Thats exactly what I am thinking. I have double checked the emitter with other components and it works fine. I have also tried a different emmitor without effect. I believe that it is just not strong enough. That was why I was curious about being able to open up the TV and put the emittor directly on the sensor? Does anyone know how to do this? Thanks...
