Defect: nu receptioneaza programe.

Cauza: lipsa tensiune de acord, 33V.
La acest aparat 33V este obtinuta din sursa de 5V (5VB) cu ajutorul unui convertor DC/DC construit in jurul tranzistorului Q200.
[Trebuie sa fiti inscris si conectat pentru a vedea acest link]

In aceasta situatie tocmai tensiunea de 5V lipseste.
Urmarind schema, se verifica in pin 3 (iesire) IC402 (KA7805), apoi pin 1 (unde ar trebui sa fie 9V). De cele mai multe ori, aceasta tensiune lipseste, datorita defectarii sursei IC400 (MP1583DN).
[Trebuie sa fiti inscris si conectat pentru a vedea acest link]

Rezolvare: Se va inlocui IC400.
Atentie la dezlipirea acestui CI. In partea inferioara a capsulei are o placuta radiator lipita pe cablaj. Recomand preincalzirea placii si dezlipirea cu aer cald.
