Most likely you can.
Most likely the old receiver has a left and right RCA analog input (it has to have an analog input in at least some sort of configuration).
The TV most likely has at least one digital audio out and probably a headphone jack.
You could either go from the 1/8" stereo headphone jack to two RCA plugs and connect it that way....
OR
You could get a digital to analog converter....and connect the digital audio output of the TV to the input of the converter and then the output of the converter goes to the stereo RCA inputs.
