Hi Luis. Thank you for answering ... I have experience with regards to mechanical repair. But when it comes to platelets, I always take it to an electronic ... and I know that the triac and resistance are burned ... ... I really don't know what the Triac coding means and by which they can be replaced ...... as for the resistances I find it simpler ..... but I go to the suggestion of people with a lot of experience like you ... because as I said before I have no experience with platelets ... and as All new experience, generates insecurity.
Dear, as you go into the subject, you will see what to acquire. Do not make a large stock of components, as these are changing almost daily. Some time ago all the Concept boards, carried the triac BT137, then went to the Z0609 and today SMD technology with triacs FT0107 is used. regards
Dear, I think that the plates with more chance to be repaired are of the Concept line, for its very simple design.
In these cases, 150, 330 and 1000 ohms resistance triacs are used to polarize the gates of the triacs. Also ceramic resistors of 10W and 6800 ohms. regards
