IR receiver punking out on my XBR

I have a Sony KDF-70XBR950 Projection TV that I bought new in 2005, which has been pretty much trouble free except for changing the projection lamps twice.

Last night, it wouldn't respond to the RCU. I changed batteries, but still no go.
I tried my cable box RCU which can operate it, and also the RCU from my Sony Bravia, and nothing.

Today I discovered that if I held the RCU within about two feet from the TV's IR sensor, it would function. I took the RCU into the bedroom where the Bravia is located, and it worked just fine, from 15 feet away, so it's not the RCU, but the TV.

I have the almost 200 page repair manual for the XBR, but it's damn near like reading Greek; I can't even determine which board is for the IR receiver.

I would appreciate if anyone could help me with this; it's something that I've never encountered before, the IR receiver dropping it's reception ability.

I can email the repair manual if someone feels they might be able to decipher it.
