Buna seara. Ma bucur sa vad ca exista un forum al electronistilor. Am deschis acest topic sa va cer si voua un sfat, o parere.Am un televizor BlueSky model BX 55 S care a crapat din senin. Ma uitam la tv intr-o seara, cand s-a oprit brusc, beculetul ramanand rosu ca si cand ar fi in standby, dar cand incerc sa-i dau drumu nu face decat sa se aprinda in verde si dupa o secunda sa revina la culoarea rosie. Specific ca in timpul in care sta conectat la priza, se aude un bazait foarte usor in spatele televizorului. Care ar putea fi simptomele? Se poate repara? Daca da, merita? Va multumesc.

incercati sursa de alimetare cu un bec de 60 w pe tensiunea de b+=115v cu etajul final de linii deconectat ,apoi daca totul este ok si aveti tensiunea de 115 v verificati componentele de mai jos.
