Hiya .. fuond in garbage: almost new boom box. JVC 3-disc CD changer etc ... nice shape. Problem: When you hit power button, unit powers up, (radio works, etc..) but then about 10 seconds later it shuts itself off. There is a "stand-by" light that lights up when unit shuts itself off ...
I have never seen a unit with "stand-by" ... i just got this today, and haven't really opened it up yet ...
thnx ...

It could be the low voltage power supply, you may need the remote for it. What is the model number? I have had many of those across the bench and they are flaky. Probably why they trashed it... I would say a voltage problem somewhere, probably heat related, a rectfyer breaking down, the amp over heating from being shorted out. Was there sound?

JVC Model RC-XC1 ... just played around with it again ..
hit power button, comes on, beautiful stereo sound for about 5 seconds then shuts off. Beside the "power on" LED light, there is a "standby" LED light: When you plug the unit in, the "standby" light is on, when you hit power, the "power on" light comes on for 5 seconds, then the the unit shuts of and the "standy" light comes on. I can't find any hidden switches, i have played with all buttons i can find ... wish i had owners manual (should go back to house where i found it and ask for the manual :)) ...
anyways, sure don't build them like they used to ... build them to throw-away now ...
thnx ...

Right off hand the only hting I can think of is an internal switch of some type. Do not recognize the model number but I have been retired from the business for a couple years now. Power supply not holding up, bad solder connection. You might get online and see how much one costs. Then find out how much to repair. Since you have $0 inveted you might get it repaired and come out on the good side. I wouldn't spend more than, in ur case, 3/4 of replacement price. Usualy I only recomend 1/2 the replace price but again u have $0 investment soooo. Give it a thought but I don't think this is going to be a repair U can do without the schematic and proper test equipment...
