Have you replaced your CRT monitor because it looks fuzzy? Next time, try to adjust it before exchanging it out.
Step 1: Remove speaker covers by pushing the tab up on the bottom and then remove the 4 thumb screws that hold the cover on.
Step 2: Remove both speakers cables on each side and the yellow molex connector on the right side.
Step 3: Slide the cover back and up to remove. Be careful not to break the tabs on the bottom of the cover.
Step 4: Adjust the fly back transformer located on the right side when looking at the monitor from the back.
Step 5: Once the monitor is adjusted, put the cover back on and reconnect all the cables and screws.
