The first time I did this repair, I didn’t see the comments ahead of time and broke the bracket, even removing the 1.3mm screws first. The second time I did the repair, I was prepared and being extra careful, but the simple act of turning the 1.3mm screw head was enough to break it. If I ever have to do this repair again, I’ll just leave the screw in and try to slide the plate out with the screw (and bracket, hopefully) still in tact, as per Kyaw-Zin Win.
Thank you hyczp and drcook!! Your tips were the answer for me. I was having a hard time seeing into the little square shaped hole with a flashlight though, so I got a toothpick and angled it so that the pointy tip was directly in one of the corners, and then slid it in as far as it would go. I repeated this with the other three corners. One of the corners will have that “little thingy” in it which will prevent the toothpick from sliding all the way in. That’s the magic corner and the one where the flattened corner of the motor brush will go.
Might be helpful to note here that this is the point where you'll remove the lid from the DM module. There are 8 screws along the sides of the top edge that hold it in place. You'll also need to remove the 4 screws that hold the molded piece in place where the wires feed through. It will make removing the lid piece so much easier. Once you remove all of those screws, you'll have access to the DM POWER board for step #4, where you'll make the repairs.
Thank you SOOO much for posting this repair guide! I am handy by nature, but soldering was completely new to me. Like others, I ordered the parts from Mouser Electronics for about $20, followed the instructions with some guidance from YouTube, and now our old television is breathing new life! A+++
