Am un cougar c.600.4 2000w . Mergea perfect pana intr-o zi cand am ascultat muzica si am miscat de el si brusc s-a oprit . In timp, el mai facea niste "figuri" adica ascultam muzica si se stingea , cand il reporneam se aprindea becu rosu si se stingea usor o data cu sursa de alimentare . Am scos toate firele frumos le-am verificat , nimic . L-am montat la loc si l-am pornit , acum becu rosu sta non-stop pornit .

 

L-am desfacut , am masurat finalii , totii sunt bunii . Singura problema care am depistat-o a fost un condensator de 50v 10uf care se incingea foarte tare si era putin umflat dar nu ars . L-am schimbat , l-am masurat si tot asa de rau se incinge .

 

Niste sfaturi ? Daca as fii avut schema electronica de la el poate as fii reusit, poate ,sa il repar impreuna cu tatal meu .

 

Si niste poze ! In prima poza este condensatoru care l-am schimbat si care se tot incinge !
