I took your advice and found the fuse was blown. I got a 6.3A 250V slow blow fuse from Radio Shack. However when I plug the unit back in it blows the fuse. What could be wrong and is it an easy fix or should I take it to a repair shop. I think the original problem was caused by a power surge as the power had gone out earlier in the day due to a thunder storm.

Re: Blown fuses in a Pioneer RX-570
Ok, it is probably not an easy fix for a layman. It may have blown output transistors, or power supply failure. As to whether it is economic depends on what has actually failed. But if it is output transistors failed, be prepared for $130 to $170 to fix it. Probably not worth it. They are a little temperamental to fix, and I recall repairing a number of them under warranty when the were new for blown output stages. It is worth getting an estimate from someone near to you. Try and use a Pioneer agent as they have experience and access to spares. Sorry this is not a fix for you, but I hope that it turns out ok for you. :)

Have you used 2A SLOW BLOW fuse? This type of fuses usually are ceramic type and are very different with the glass type ones. The glass type fuses are (more or less) fast blow. Although the best solution is to find SLOW BLOW fuses like this, in case it's very difficult you can use 3A fast blow fuse also.

I would guess that during the move, the speaker wires crossed and smoked one of the output amp sections. The output transistors are shorted and are causing the fuse to blow. If you can post hte model number, I'll try to get you more specifics on the parts that will need to be replaced.
This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.
The JVC RX-884VBK is a great machine, I had it for over 5 years and had no problem at all. I came across the (NO SOUND at all) and I believe it is an easy fix. Check the Front left, there are 2 keys marked 1 and 2 for SPEAKERS output, sometimes you don't notice that you connected the speakers to 1 and the 2 key is pressed. You could have both keys pressed and you will get the sound. I hope that helps.
You CAN open the unit (keep in mind that even unpluged there is still voltage runing through the system, so.... dont fry) and you will notice, if the face of the unit is towards you you will see on the left hand side a power supply board, the fuse is on that board, and it is a tube fuse, 125V 8A. Most stores do not carry the 125V version anymore, but will carry a 250V. This is okay to use where the voltage is not the main purpose of the fuse.
