Verifica R805-0,27ohmi, R806-4,7ohmi, R808-220ohmi, R804-100Kohmi, D805, D806,D807, preventiv schimbati cei 2 electrolitici din primar, pune bec in loc de final linii, si daca nici asa nu porneste, atunci STRW6753-nu e bun. Eu am patit asa, am cumparat 3 buc din diferite surse si la preturi diferite si nimic pana nu am pus unul din recuperari cu care am rezolvat toata durerea de cap.Succes!cu stima!
