Hello, the 390V varistor has blown because there was probably a break in the neutral on the 230V electrical network, which caused the voltage to rise to 400V. it is imperative to replace the 390V varistor which protects the power supply board from irreparable destruction. apparently, the 400V peak may recur on the electrical network.
if the voltage rises above 230v, it is for the protection of the power board. but if you don't have 14D391K at the moment. I explained in the video that it works even without 14D391K. yes, it is for the protection of the power board if the voltage rises above 230v
Outstanding work 👏

Great fix thanks I’m surprised the LEDs aren’t showing where they’ve burnt their way through the Perspex 😊
Emeğine sağlık ustam. Sağlık ve hayır dolu günler dilerim.
v.good my dear thank you
good
Good 👍 👍
Ok.i varistore servono per proteggere i circuiti da picchi di tensione .Penso che andrebbe rimesso uno nuovo
If this happens agian the tv is completely dead. So better replace the broken part.
Samsung 1 Bad tv ?
Ola amigo saludos porq Nole puso el varistor
