Salut.

 

Mi-a adus un prieten un tv samsung le37c530 de 37 inch, la care bazaie foarte tare transformatoarele din invertor. Se poate face ceva, sa torn pe ele hot glue, sau ceva de genul?

Tv-ul este functional, doar ca bazaie, si destul de deranjant. E relativ nou maxim 2 ani are.

Am vazut condesatori de calitate in el, deci nu cred ca picau asa repede.

Am incercat sa schimb luminozitate contrast etc, si nu se schimba nimic, insa daca selectez eco - normal, isi schimba frecventa.

 

Daca apas pe ele, se modifica iarasi sunetul. Nu se incalzesc.
