I have a motorized projection screen i purchased from ebay a few years ago. It came with a 3 button rf remote, and a control that is wired into the power cord to be wall mounted.

The hardwired control works fine, but the remote has stopped working. It still lights up when you press the buttons, but i am not sure if it is sending a signal, or if the receiver is the problem.

I have been unable to locate the remote online to purchase another, nor do i know what frequency it is using.

Any tips on where i should go from here? a place i could find another remote, a way to find the frequency, receiver troubleshooting? I don't know which way to go on this.

The screen is 120 inch richvision, and the remote is a 3 button remote with Pioneer on it. it has a up arrow, a stop button, and a down arrow. black in color. no model number or anything.

I appriciate any help you could offer.
Thanks
