I have acquired a vintage Brother SX-14 electronic typewriter. I know how to type but unfortunately I do no have the instructions to carry out all the functions of this typewriter. I just want to know how do you store and print what you have typed? This typewriter has a code button and a store and print button. Thank you for any help you can give.

I have to change the mother board on my
samsung ph 59d6500 tv and I want to know if I have to do something to the firmware after I put in the new motherboard or is that all I have to do. The tv turns on with the samsung logo and then switches off after it says something about hdmi if that matters.
