Sorin Schiriac Posted October 29, 2007 Share Posted October 29, 2007 model 21MX132, CHASIS itc008 Cu procesor TDA9554PS/N3/3 memo 22c04 are o manifestare dubioasa: totul functioneaza normal se aude sunetul dar imaginea se intrevede putin cind maresc G2. am schimbat memoria si se manifesta la fel .tind sa cred ca e un defect prin jurul baleaj vertical. poate ati mai intilnit acest defect ca eu nu-i dau de capat.

Guest Posted October 29, 2007 Share Posted October 29, 2007 Valoarea lui G2 e normala sau mica.Scoate soclul de pe tub si verifica tensiunea de focalizare pune scanteia in evidenta.Parera mea e ca lipseste.Concluzia o tragi singur ,(schimba traful) Link to comment Share on other sites More sharing options...
