I tested one of the 470uf caps on this Chinese crap LCRZ meter that has a test function but I am never sure if I am using it correctly.

Well the cap was reacting strange to the test and I decided to change that first. No go.
I then read the theory of operation on the VDM and thought it might be the size signal from U8 so I did a similar test you had me do before
but the issue stayed on the blue, not the DAC. So I removed U900 and put another one in now that I had the other cap in as well.

It worked! So now I know what to look for if I see that issue again.

Thanks Ron!

I figured it was still U900 causing your problem. I'm not sure on the subscription question. I'll see what I can find out.

Go to your profile, then edit profile, then notifications and select which features you want to be notified and how, forum or email. The only problem looks like when a thread is updated you only get 1 email per day. I imagine the only way to get an email for each post update would be to upgrade the forum, which may be a future possibility depending on the forums success.
