I just purchased a VSX-521-K (new from woot). It was working fine the other night. But last night when I went to use it, it was dead. It would not turn on. I disconnected things one by one, and it would still not turn on.

Before I pursue contacting Pioneer, are there any simple things I can check? For example, is there an internal fuse I can get at if I open the unit?

Thanks,

/greg

Probably not without invalidating the warranty. But I think you are right, it sounds like a blown fuse.

Yeah, I would expect so too, but you know, the unit was so cheap, that if I was reasonably confident that I could simply replace a fuse, I wouldn't be concerned with the warranty.

There's no lights, clicks or anything when I press the power button, so it's got to be something right up front. And, based on other things I've taken apart, there's usually a fuse (sometimes soldered, sometimes not). I guess I'm just looking for some confirmation that there is one...

Same thing happened to me a few days ago. I just bought the thing last month. I emailed the company I bought it through.

I heard this model had a lot of problems. I hope that pioneer fixes the problem with your receiver for you.

I am having the same problem, but i have no warranty... I am wondering, how hard would it be to replace the fuse, if possible? Also, would you know where to get the diagram?

If you have no warranty, just take the screws out and remove the cover. You should be able to see a fuse if it is in there.

Unplug the receiver first though.

Same issue. Was hooking up speakers after moving furniture then it died. About a year old. Tool the panel off. Only fuse near the power supply looks ok.

What next?

I'm having a similar problem with my unit. It's about a year old, and I've hooked up a projector to it. I was playing ps3 and it suddenly shut down. I've tried everything, but it won't turn back on. Did you manage to solve your issue?

Same issue. Bought this receiver off Woot and it died back before Christmas. Just got around to trying to fix it and wanted to see if anyone else had the issue. Apparently it's junk judging from all the other people this happened to. Woot often has good deals on receivers, now I know why. I turned it off one day and it has never come back on since. Probably a capacitor issue. Anyone had any luck fixing it?

Same problem with mine. If someone has an idea what the problem is, it'll probably be easier to do some voltage testing to find out what's wrong.

I guess there's some comfort in knowing I'm not alone. Got what I thought was a good deal on this receiver from Newegg. Appeared to work fine for about 6 months. Then it just died. One moment it was working, then the lights went out, and it's been a brick since. I'm not giving up on this yet. If I have any luck, I'll post my findings here.

Took in for warranty last year. Took two weeks. No charge. Needed new circuit board. Still working great every day for my family room system.
