I just purchased a Panasonic DVD-RV32K dvd player. I connected it to my TV: General Electric tv manufactured in 1990. There are three inputs in the TV (red, white, and yellow) which i connected to the DVD player. I tried putting the TV on channel 3 or 4 to see what channel plays DVDs. With the main TV in the house, I can just go to the different Video input menus, but this TV does not have that option. Need help, please! I hope my TV isn't too old to play DVDs.
