A cordial health to all and grateful in advance for their grain of wisdom that will contribute to this small inconvenience. I have brought the equipment in question and it turns out that it is missing a component that locates in the diagram effectively but I do not know what model it is. The component that I need is the following: IC621 [url = / ver-adjunto / aHR0cHM6Ly9jZG4ueW9yZXBhcm8uY29tL3VwbG9hZHMvZGVmYXVsdC8wMDAyLzg1L3BhZyAxMS0zNjA3Ni5wZG/g.p/g.ng/g.ng/p.ch/png/png/png/png/png/png/png/png/png/png/pp_wp.p/g.png/png_wp.png # # Regards..!!

In the circuit that went up, the number of the component IC621, SE120 is clear. Victor thanks for collorating me with the solution!
