Are you sure it is infrared remote and not ultrasonic?
My family bought an RCA 25" color set in I believe December 1981 or December 1982. The remote was ultrasonic. The original remote broke a few years later, and I bought a replacement, Phillips ECG RT114.
That set had the best adjacent-channel rejection of any I've seen, but the red was brownish and even strong signals gave a picture with video noise.
