Please help ID the part in the pictures. This is a board for 7" LCD (cheap from ebay) and the part in the pictures came off. Soldering is not easy and wanted to ID and potentially replace it. It has markings 101 on top of it and is shaped like a cylinder with wire wrapped around it (sorry, I am complete amateur in this).
there is also another part with a similar shape, slightly larger and with 220 marked on it. I measured resistance across both and they both have about 1.6ohm resistance (very low). So, not sure what they do but LCD backlight will not come on without the “101” part soldered back on.
