Dac-12m019 aor

[bill25]

Hello guys and happy new year. I have problem with the dac-12m019. I need to know the component (D104) on the TEA1532A on the Hot side of the psu. I search for schematics and nothing found. Thanks

I looked at a different board and it looks like D104 is the same as D105 & D106
which are likely RLS4148NTE-11
I believe the small feedback winding on the transformer feeds R133 (1Ω) then to D104, that charges C131. So any fast recovery diode should work

Thanks you very much for the info. I'll try it tomorrow and come back to tell you what happened.

I replace with 1n4148 diode and nothing happens. No volts no stby. Also i replace the TEA1523A. The voltage across the main filter cap 450v is correct
