I no longer have the original remote for a LXI TV made in 1986. I don't know if a replacement is still available.
Now that I have cable service I cannot receive all the channels that I do on my new set. I need to get to the menu to reset the channels.
you could try www.cpc.co.uk for a replacement handset just like the original or if you have a local TV repair shop you could ask them to test the handset for you sometimes the solder holding the led breaks away hope this is of some help to you
