Steps:

  1. Read and follow the iMac Intel 20" EMC 2105 and 2118 Display Replacement guide, and remove your screen completely.
  2. Flip the screen over, placing it on a towel to keep it safe. Locate the manufacturer's sticker on the back of the screen, which should contain the screen's Model Number
  3. The screen used in this particular iMac 20" A#### EMC#### is an LG-brand model-LM201W01, though yours may be different.
  4. Search either AliExpress.com or Ebay.com using the search phrase “Your-Screen-Model-Number Control Board”.
  5. If your iMac is a 20", they should be around $30-$40. If 24", $60-$80.
  6. Order the video driver board for your screen. It will probably ship from Asia, and take 2-3 weeks to get to you.
  7. It probably will not come with a power supply. This is normal. Most video control boards require 12v 5A power supplies. You may have one in your spare electronics bin, so check there before buying one: Old routers, PC laptops, etc may have compatible power supplies.
