Hi, read. Always before a vertical break you must change if or if ALL electrolytic ones for new ones. Do not leave an old one. In all that circuit. Doing so will give you a job guarantee. And you won't have customer complaints.
Salu2 to all colleagues

Hello Friend. before changing the ic. vertical changes to new all filters that are related to the ic. vert. and change even if the diode that feeds the ic is good. Vertical if the fault does not improve, check the resistors that feed the diode, whether it is powered by the flayback or the choper. Cheers
