Question about Audio Players & Recorders
Hi robotek. one day when my nad t562 dvd player was only about 18 months old, a component that looks like a large resistor on my power supply scorched the board and the capacitor next to it. i didn't have a proof of purchase, so i didn't pursue warranty repair. now that i know how to solder, i'm wondering how i determine exactly what the parts are and if i can replace them on the board, or if i need a new board and where i might get it. i have not heard back from nad tech support. i can send photos.
I would replace the capacitor first and check the resistor with an ohms meter to see if it has changed in value(gone high). remounting the resistor (you may have to replace it also to do this with longer leads) to be clear the Pcb and also the capacitor to be as far away from the resistor as a heat source also may help. Darkening of the board is not uncommon where there are power components. Having said that, it should not generally happen in the first place... but it often does. Power supply failures in modern gear relates to heat stress so often. Capacitors failing from this overheating is the biggest problem of all. In the workshop, where we suspect that caps have failed, we generally replace them all, and always use good brand name 105deg rated devices(Rubycon or Nichicon brands i prefer) to help minimise the recurrence of failure. You can order them from Farnell in most countries of the world. If you cannot identify the values of the components, I am happy to try and help you here. Please feel free to ask any questions you may have. FixYa rating is the best way to thank me for helping you out. Cheers
