HC 90 Cu defect

Recommended Posts

Am ales sa scriu aici, m-am uitat prima oara la vintage si nu am gasit un domeniu bun, acolo fiind despre tuburi..In fine, vreau sa pornesc un HC 90 Ice Felix.Treaba e ca functioneaza, insa Alb-Negru si nu imi dau seama din ce cauza poate sa fie.Am anulat modulatorul RF inclus si am aplicat iesirea video direct la intrarea Composite la TVPrin modulator e la fel. Am dat vina pe un integrat KP556PT4A, care se cam incalzeste. Aparent e rusesc. E langa modulatorul RF.Am gasit pe net o schema sa fac un cablu de la iesirea lui de monitor CGA, la Scart RGB. Un sfat ar fi bun, daca a facut cineva, sa stiu daca ar functiona.Cateodata vine imaginea color, dar nu cum trebuie. Are umbre de culoare, si ce ar trebui sa fie verde, apare cu umbre de albastru, si exemple de-astea. Doar pentru 1-2 secunde.

Multumesc mult pentru acel link, mi-a folosit mult, dar nu pentru ce voiam eu.Am rezolvat-o printr-un cablu RGB fortat la Scart, gasit pe net, si descifrand manual pinii, pentru ca nu i-am gasit prin documentatii. Merge frumos color acum.Multumesc inca o data!
