screen

i have an arduino pro mini hooked up to a pcb and i partially programmed it but i ran into some errors. The screen only turns on when i touch 2 pins on the back where the screen header is soldered. I soldered a lot of little smd capacitors and resistors. Did i solder something wrong? Is my screen toast?

By screen, do you actually mean a LCD ?

Without knowing what you have, how are we suppose to know if you soldered something wrong?

OK, so far you are simply posting nonsense, for what reason we have no idea.

You need to cite the website which details the specifications of this screen or module, possibly the retailer from which you bought it.

Unless you provide this information, no-one is ever able to help you, whether or not they wished to.
