[QUOTE="Tururu, post: 950030, member: 227656"] In general, all power supplies are bad clone (since 2008 have DB800S-HD clone and original). No load/consumption, measured in vacuum well, but under load, the output voltage falls. The original power supply is easy to know what is, weighs twice, never saw a malfunctioning. With the passage of time, and now rather bad, it's normal. Their life expectancy has been 7 months (24 Hours/7days) [B]capacitors have 5.000horas of life (not a mistake, it is in their characteristics, are very inexpensive)[/B], after two years of often poorly. The LED on the power supply when trying to move the engine off/attenuates, if you feed a LED 12 volt 10W to really like "flashes" for this problem. [B]The tuner screen also tends to blink[/B]. The bad have 2 capacitors in the output filter [B]220μF, 16V[/B], in good times are from [B]680μF 16V[/B], endure longer, always one will be busted (for RFI switching) switch 2 [B]for switched it to 105ºC[/B]. [B]1.000μF 20V capacitor (go well) 105ºC[/B]. If the original was tested with the same power supply, the problem recurs. About the antenna cable, as they say locates peers with live wire (center wire) of [B]1.13 millimeters and if you find of 1.33mm[/B]. with overall diameter less than 10 millimeters, perfect. -------------------- En general, todas las fuentes de alimentacion clon son malas (desde el 2008 tengo DB800S-HD clon y original). Sin carga/consumo, en vacio miden bien, pero con carga, se cae la tension de salida. La fuente de alimentacion original es facil de saber cual es, pesa el doble, nunca vi una averiada. Con el paso del tiempo, antes bien y ahora mal, es normal. Tiene en el filtro de salida unos componentes criticos y esperanza de vida son 7 meses (24Horas/7dias), [B]Tiene condensadores de 5.000horas de vida (no es un error, esta en sus caracteristicas buscando por internet localizas esta informacion, son muy baratos), despues de 2 años suelen estar mal.[/B] El led de la fuente de alimentacion al intentar mover el motor se apaga/atenua, si alimentas un led de 10W a 12Voltios veras como "parpadea" por este problema. [B]La pantalla del sintonizador tambien suele parpadear. [/B] Las malas tienen 2 condensadores en el filtro de salida de[B] 220µF, 16V[/B], en las buenas son de [B]680µF 16V[/B], aguantan mas tiempo, siempre uno estara reventado (por RFI de conmutacion), cambiar los 2, para conmutadas que sea de 105ºC. [B]Un condensador de 1.000µF 20V (entran bien) 105ºC.[/B] Si la original se probo con la misma fuente de alimentacion, el problema se repite. Sobre el cable de antena, localiza como dicen los compañeros cable con el vivo (hilo central) de[B] 1.13 milimetros y si lo encuentras de 1.33mm[/B]. con diametro total inferior a 10 milimetros, perfecto. PS: Minimo 3Amp. 12Voltios.[IMG]http://www.imagenonline.com/img_a5995.gif[/IMG] [/QUOTE]
