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

Sorin Schiriac Posted October 30, 2007 Author Share Posted October 30, 2007 tubul e bun tensiunile sunt bune cred ca un tranzistor ceva din asta digital ca e plin cu din astia,ar putea fi defect,poate are cineva vreo idee. Link to comment
Guest Posted October 30, 2007 Share Posted October 30, 2007 Tranzistor trebuie sa fie ...!Acum vreo 3 ani am avut din cate vag im-i amintesc ceva de genul asta.Nu mai retin exact tipul de sasiu insa am gasit un BC 548 in scurtundeva langa radiatorul tanzistorului final linii cam la jumatatea placi.
