I have an older model of a tobishi tv , and we are on the second remote , which is dying out like the first one.
sometime there are certain numbers that won't work.
you have to play around with them , very irritating.
I was wondering if maybe it just needs cleaned , any help for me would be nice , thank you , nana
Often under the buttons there's a rubber membrane with conductive panels which make contact with the circuit board when the button is pressed. You could try remove the membrane and wash that (only replace when 100% dry), and get a can of PCB cleaner in the likes of maplin to clean the circuit board contacts.

if you go to a service centre/decent shop, they will sell you a remote they program for your TV, a generic remote but all functions for your TV....cost 20-30
