[QUOTE="Tururu, post: 884243, member: 227656"] Pon un poco de pasta termica en la chapa, que toca el chip de comunicacion I2c del tuner Alps, si no toca bien, se puede quemar. ------- Put some thermal paste on the plate, playing the I2c communication chip tuner Alps, but plays well, can burn. Unas fotos de una DB7020[B]S[I]i[/I][/B] (rev. K 2004) con tuner Alps que repare . El sintonizador Alps usa la chapa del chasis como disipador, al estar mal montado, no disipa el chip STV0299B y averia por temperatura. Funcionando OK, sin la tapa metalica, en unos minutos quema, pasa de 50ºC sin disipador, las 2 que tengo, estan con pasta termica para no tener averias. El mismo chip en el sintonizador Philips trabaja frio, en la foto de arriba no tiene disipador y no lo necesita. ------- Some photos of a DB7020[B]S[I]i[/I][/B] (rev. K 2004) with tuner Alps to repair. The Alps tuner uses the chassis as heatsink plate, being poorly assembled, no chip dissipates STV0299B and breakdown by temperature. Running OK without the metal lid, burning within minutes, turn 50°C without heatsink, 2 that I have, are with thermal paste to avoid breakdowns. The same chip Philips tuner works in cold, pictured above sink and no you do not. [/QUOTE]
