You are a master technician well done. I had a DENON PMA-700 AE AMP that blew when in use for roughly 30 mins. It also blew my crossovers in my CERWIN VEGA VE 8 2 WAY SPEAKERS but luckily I repaired them. The amp was returned to manufacturer for refund.
Repair is very important, it reduces usage of materials, ammount of toxic waste & use of energy ... Yes, as seen in this video shorted capacitors (but in most cases cylindircal electrolytics) destroy transistors & rersistors, also charred parts bords are a big short circuit & must be removed as shown ( or the entire bord scrapped), you let it smoke for far to long ... Omg of course wait until it heavily smokes (the ortange glow was already a sign of a short circit) ... you (again) defeat protective earth at 0:05 ( = electrocution risk), this is a Class-1 device (metal chassis) that needs protective Earth, this this German ( & Korean) Schuko-plug is earthed ( = the recessed side contacts of this yellowed grey plug) & requires an earthed recessed Schuko-outlet (Germany & Korea) ... the "60Hz" at 0:28 shows this device was made for South-Korea (North-Korea has 50Hz like Germany & former Soviet Republics) & of course Korean letters confirm it ... P.S. German plugs in a German outlet are much saver than USA/Japan plugs & outlets ( = I got never shocked in 230V ( + 400V) Germany)
@@agurobe Yes you can. You just need to make sure the PCBs are dry. Notice how he used the hot air gun or blow drier ? I have even seen guys pressure wash the innards of a dirty old amp/ receiver. It's fine just as long as you don't apply power to the item until it is fully dried.
Para los que comienzan diagnóstico y reparación de este tipo de equipos, nunca haga lo de este vídeo ya que pueden provocar un accidente y lesionarse a ustedes mismos...
Super
..............BISOUS BONJOUR DE LA FRANCE BIENVENUE JADORE CONTINUER MERCI
Не удивлюсь, если прогар в плате - результат включения усилка в сеть ради "красивого кадра" в ютубе

These heat sinks are huge
washing solution???
It's only a mild detergent. Nothing fancy. It's just to clean off the dust and light grime.
@@tonymontana897 you can use soap an water to clean electronics in repair?? wow?? cool

Да, дыму прилично было.😅
👌👌👌👏👏🤓
magic smoke!
At least he didn’t ruin a perfectly good fuse….

Why not start it through a light bulb? then there would be no smoke! 😏
because you have to connect a light bulb in series, then it won't burn out!
😎😎👍👍
Ne jamais brancher directement sur secteur un ampli non réparé !
Mettre une ampoule à filament en série pour éviter de tout cramer !
Thank you very much!!!
Задача была - что - нибудь сжечь эффектно, а потом ремонтировать, один паяльник чего стоит.
Yes dim bulb test.
This "master" doesn't know that it turns on via a light bulb?
Жечь усилитель ради контента- не профессионально!
Oreg amp okey
Throw it away!
