catalin004 Posted September 18, 2019 Share Posted September 18, 2019 Salutare...am la reparat un CRT la care imaginea este ca in poza...adica dungile drepte verticale sunt ondulate...(nu zimtate). Am schimbat C-ul de pe 400V, conzii de pe B+, toti conzii BV si cel de pe driver H...am verificat pe osciloscop toate alimentarile tunerului si uC....toate stau sarma. Am mai patit asa ceva insa era din condul din primarul sursei... https://postimg.cc/7fV8gBZ3 Link to comment

catalin004 Posted October 14, 2019 Author Share Posted October 14, 2019 Am schimbat jungla si defectul a disparut. Incepuse sa vibreze mai rau si a venit inapoi. Link to comment
