I forgot to mention:

If you've been diagnosing by swapping parts, be aware that changing the 
A3 is the same as changing the SRD - they won't necessarily match 
anymore, so would need adjustment.

Maybe your original SRD was just fine, but the whole set needed 
adjustment. Who knows what may have been tweaked or mis-tweaked by 
individuals working on it previously. If the original SRD is intact, 
just check to see if it's still a diode (should look the same as a 
regular Si diode, with maybe a little higher forward voltage drop). If 
so, it's probably OK and can be returned to service.
