RGB verificat,sigur bun,nu am diferente de culoare si rastrul este corect,tensiunea de alimentare este corecta,final BV nou,sigur bun.PROBLEMA nu am schema sau date despre TDA 4780.Tubul are luminiozitate forte buna si nu-as crede ca din el provine problema,reglajele de lumina/contrast/culoare-le executa corect.Adevarat tub A66EAK.Cred ca va ajunge la fier vechi.
