The photos you show in this tutorial are NOT the Mitsubishi WD-65735. I performed step one, and the inside of my TV (which is a confirmed WD-65735 as proven by label on the back) does not have the layout shown in this tutorial, and in fact, is not even close. Perhaps you mistakenly posted the incorrect tutorial for WD-65735?
Hi Walter,
Sorry the blog was not helpful. The photos were more of just a guideline. If you head over to our forum and sign up, you can post a message asking for the specific photos. There should be someone on the forum who can help. There is a large community of experts that are ready and willing to help you get your chip changed and any other help your need.
I’ll ask someone from our office to look into getting the photos as well. Thanks for letting us know.

E Z Peezee, sort of. Found that even though I have a WD-65735 the screw counts and locations were different than these instructions, especially in the box and circuit board around the chip I was replacing. Figured it out and now have a running TV with no “stars” on the screen.
Thanks,
rj
