not sure what "massa" is. that would sort of label what it is. But from a quick eyeball, its a +12V regulator.

LC TDK PSU issues

Wrong pinout.
Now I am thinking it something else, it has +12V, a GND, but it also has +5v going into it. That is very strange for a regulator.
I dont have a TDK supply handy to figure it out so thats about as far as I can go.

The more a stare at it, the more it looks like a dual diode. maybe a clamping network.
The badcaps forum (what a funny name :beige: ) has a board dedicated to PSU troubleshooting and repair. You could ask there if they can identify that mysterious component. There are several people around there skilled in the art...

Ah, I remember that forum. I used to frequent there alot back in the day.
Thanks for the link, but I think the best solution is to see another tdk 699-0153....
Well, if you can get a replacement PSU of the same type for little money, go ahead! If not, it's worth trying to fix the existing one as I did with my old Astec PSU (still working after been fixed). BTW, a quick ebay search reveals a used TDK 699-0153 for 79,95 € + shipping from Germany to Italy. I bet the fix is cheaper...
Another attractive option is to attach a modern PSU with compatible voltages and wattage...
I agree. That PS is similar to the Sony PS in my HD20 SC I recently worked on.
Here's an image of the corresponding components in the Sony PS. Also apparently unmarked.

Yes, they are not exactly the same. My point was I agreed with Techknight's observation that your mystery component looks like a dual diode.
