Recommended Posts

"palpaie de vreo 7-8 ori nu stiu ce defect indica ma puteti ajuta cu ceva solutii" -pai hotaraste 7 sau 8 .

8 = eroare in memoria interna IC 7600 ;

7 = urmareste circuitul SCL , SDA care undeva este pus la masa : tuner (pinii 4-5); IC7250 (pinii 7-8) ; IC7600 (pinii 49-50) ; IC 7601 (pinii 5-6); IC 7833 (pinii 9-10).

va rog sa-mi spuneti si mie unde se face tensiunea de 8v pentru procesor ca in schema pe care o am eu asa vad ca tensiunea de 8v se face din trfo linii si as avea o rugaminte daca poate sa-mi trimita cineva depanatorul nr25 pagina 19 (STARTUL LA SASIUL L9.2E) ca m-am blocat cu acest sasiu cu aceea tensiune pentru procesor va multumesc pentru intelegere.

daca are imagine este tub obosit,tastati rapid 062596 i (i=OSD) si la setari tuner micsoriti cl spre 0 CL-0,in unele cazuri trebuie pus pe alt tub pentru aceste setari,sau regenerat tub,supravoltare filament.etc

Va salut. Multumesc ptr. schema . Se pare ca tubul cinescop,. este cu probleme . Am incercat pe ,singurul tub A48 disponibil Tip. A48EAX-13 si TVC nu porneste din St. By. Am incercat cu A51-595X3620 , TVC porneste , nu mai trece in St. By dupa 10-20 sec . daram lipsa 2cm  St . Dr. desfasurare pe orizontala. Nu cred ca pot sa-l schimb in carcasa TVC Phililips.Ce alt tip de TUB A48  se mai potriveste ,fara modificari ? Cu stima , Virgil.
