Topper thanks for the advice, I enabled my vcard. And yes you’re right it is a Turkish receiver, the company’s name is Yumatu and the model is MX. It is based on the Single-Chip Set-Top-Box Decoder: STi5518 and a schematic from any receiver with the same decoder will suffice. For example Digital 3000, Globo 3000, Opticum 3000T, Opticum 3000 TS, Digital 4000, Digital 4000CI, Digital 4100, Digital 4100CI, Opticum 4000, Opticum 4100, Globo 5000, Globo 5000CI, Globo 6000, Globo 6000CI, Globo 6000CR, Digital 6000CR, Digital 6100CR, Globo 6010, Globo 6010CI, Globo 6010CR, Opticum 3000L and many more have the same electrical schematics. Any help would be greatly appreciated.
