I have this digital display and the board it attached to. Sorry I'm really new at this. I scrap alot. But have never separated any boards. Thanks for the help.

Turn the little metal tabs on back of the board and remove the screen. Any screen attached must be removed on boards, j fyi. Should make Low Per.

Remove the YELLOW round thing on the larger board. That is a battery. No batteries of any kind are accepted or allowed on boards, j fyi. Carefully slide a small flat head or grab with needle nose and just rotate, 360. The welds separate very easy from the tab instead of removing everything from the board. Should make High Per.

...and if screen is still attached with solder pins, nip the pins as close to the screen when removing with a wire cutter(nips). I save up the screens and eventually go around to different cell phone drop boxes. Scatter them around in all the different boxes in different assortments. In hopes they get recycled. I have a few places that take them but not all.
