i got a used tec ma 1350 when i plug it up all the lights light up and nothing works no matter where the key is set some times a error will come across the screen
All lights on a TEC indicates loss of program. Battery is either flat or stuffed (best to have it replaced). Then it will need programming.
The programming manual is a rare beast. Only one I know of is here ...
