Sanatate !! La acest tv 2000T MK8 , am gasit defecte in primar sursa : Q601 . Q605 . D611 . R614 ... Am inlocuit componentele respective , si restul componentelor din primar  , am verificat si erau bune .. Chiar daca erau ok la masuratoare am inlocuit si Q603 . Q604  si Optocuplorul !! Am pornit tv si a functionat aproximativ 20 de min . dupacare sau defectat dinou exact aceleasi componente !! Am luat dinou la ferificat toate componentele din primar .. tranzistorii si diodele le-am scos din montaj si asa le-am verificat ,, toate sunt bune ... ce sa mai verific inainte de a inlocui dinou piesele defecte, deoarece sunt sigur ca se vor arde dinou ... in timpul in care a functionat , am masurat tensiunile secundare si erau normale !!  In locul lui Q601 (2SC3979) am pus un tranzistor recuperat din primarul unui monitor CRT ..
