Should I test the diodes?

What about +15V (TP82) ?

Measure voltage on either side of diode D480 on start up. Looking for where the SOS7 signal is coming from.

Getting 15v there.

That thing is super small. Hard to get a reading but it gave me 3 for a split second and then went straight to 0.

Weird new symptom. Before when I started it up it would click, SOS7 twice then turnoff. Now it just stays on and does the SOS7 over and over. Not sure if that has any meaning.

Need separate readings for anode and cathode of D480 (black probe on chassis ground).

No idea about that. Usually it just repeats as it sounds like it's doing now.

Anode .3
Cathode .2

You might need to set your multimeter on peak/max hold mode to catch the SOS event. You should get 4 to 5V briefly on the cathode if you're getting SOS7. This would also show up at test point TPSOS7 obviously. If you're not getting voltage there just before the error trips then possibly the A board is misdiagnosing.

Retested the Cathode and TPSOS7. Got 5v on both.

So the anode?
