Greetings!
I am new to the forum and I see a lot of these models with this symptom. I'm working on one that is stumping me and hoping to get some help. I suspect the Y-SUS, however none of the fuses are bad, which makes me a little doubtful. The IPM heatsink never gets warm, while conversely the Z-SUS heatsink DOES indeed get warm. I would suspect a bad IPM on the Y-SUS, but the lack of a blown fuse makes me wonder. Can anyone offer any help?
I also pulled the Y Drive/buffer out and measured it for shorts, but it seems to be fine. My next step is to pull the Y-SUS and check the IPM for shorts using this guide:

I will see what I find.
When the IPM blows, do the fuses sometimes remain intact?
Okay, so I pulled the Y-SUS board and the Y-SUS IPM measures okay in the 6 tests Coppell TV lists. I can't seem to be able to find a problem on the Y-SUS. I then pulled the Z-SUS and it's IPM also checks okay.
If anyone has run into one of these sets with no bad fuses, but symptoms of a bad Y-SUS, please reply! Thanks!
