Hello!
This is Orione chassis on the OECF004A processor, unfortunately I do not know the options for this processor.
Service manual -> https://www.elektroda.pl/rtvforum/viewtopic.php?p=793877#793877

The first save your originall dump. Then go to data set mode ( Volume - and 6 ) . I think you can use 21V13D ( BG-DK OECF006A TMA528A ) or 21V13F ( ( BG-DK-L OECF007A TMA528A or TMA528C ) options :
21V13D

21V13F


For VHF replace tuner with KS-H-142EA or KS-H-146EA

Thank you very much!!!
