help for Trinitron kv-m1430a Dead

[bigboss80]

Hello everyone, a month ago the Trinitron kv-m1430a suddenly died, I use it to connect my old video game consoles, it has turned off and no longer shows signs of life, in fact the red standby LED is also off. 'I opened to try to understand what had happened to him and on sight there is nothing burnt, I started to do some measurements and first started from the fuse and it is ok, then I got to the 400 V 220 uf electrolytic capacitor and until there the voltages are present, then I went up to pin 3 of the transformer and they arrive 323 Volts, then to C 609 and from the diagram there should be 120 Volts but I can not find anything,
then I went to measure the voltages on the STR54041 which should be a voltage regulator and the measurements I made are all wrong, from what the diagram tells me.

Str54041
1: -17.2V
2: -17.2V
3: 187 V
4: -17.5V
5: -17.5

After various checks I managed to find a shorted component, D611 a zener R2M, I disassembled it, I gave voltage for a second and I saw that the TV led turned on, then I ordered a new R2M and replaced it , as soon as I switched on and blew the diode again. So I thought it might be the STR54041, I ordered the STR, I mounted it and just turned it on and immediately blew the 4 Amps main fuse, yesterday I reassembled the old STR and the original shorted diode to see if anything happened, as soon as I given voltage and jumped R601 from 3.3 ohm. I don't know what to do anymore, it's getting bad.😔

this is the electrical diagram
