So there is no A-board, but DG(TNPA4226), H (TNPA4177), D (TNPA4133), PA(TNPA4178).
Maybe download the service manual http://elektrotanya.com/panasonic_th.../download.html
See if you can check +15V_S is going to the H board at H3 pins 21-23, delivered from PSU P6 pins 2-4 via PA board, in PA6, out PA3 , in H3
H board IC2301 needs Sound15V, Sound12V. Sound12V is generated from the Sound15V(+15V_S) by the voltage regulator IC2303.
It appears IC2301 generates the SOS, and a high is operate, a low is SOS so i guess if there was no 15V that would mean a low from that and trip the SOS12.
I've got no experience with this generation so I'm just going by the schematic since there's no mention of any voltage checks.
It may be the case that you will have to hook up the probes first and then power on to detect the 15V because I expect SOS12 will kill the 15V when tripped.
There was another post for similar problem with no result unfortunately.

Manual shows P or H board as first checkpoints in the blink chart.
