Where is the IR receiver in RCA rear projection TV?

Question

I have an RF remote with an IR retransmitter. This retransmitter has little flasher uints that you stick on the component you want to control. I have an eight year old 60 inch RCA rear projection TV, chassis number of PTK195AC (model P60812BL) that does not work well with these if I put them on the front of the screen. I am going to have to find the actual IR receiver and stick one on it if I want to use these with this TV.

Does anyone know where the receiver unit is on the chassis? What does it look like. I have been all over that chassis, but I don't even see any discussion about the IR receiver in the service manual. I know it is there someplace, but it will take a good long while to find it and I thought i would ask you folks, since you have helped so much in the past.

Do a binary search. Cover up half the TV and then operate the remote control. Then cover up half of the appropriate half, and then half of that half, and so on.

It's inside the TV, mounted to the top of the light box, and aims atthe mirror.  The entire screen of the TV essentially becomes the IR(window)  of the TV.

Depending on the model, it may be accessed through the back or may require removal of the screen assembly. Suggest obtaining a service manual for your specific product to facilitate your search.
