Malfunctioning Pioneer XC-IS21t

I have a Pioneer XC-IS21T and haven't used it for a few years. I went to use it yesterday and in does not work. Everything seems to be working properly, but there is no power to the speakers. This unit has a separate amp with a gauge that monitors the power. All the lights turn on, the cd spins, the tape deck operates, the speakers just don't speak. They don't even make a hiss. I know the speakers are ok because I hooked a battery to them and they made noise. The problem seems to be in the amp. When I turn the volume dial, the needle on the gauge doesn't move. The amp makes a clicking sound every time I hit a button on the main unit. It might be a problem with the power switching(?). I took it all apart and could find nothing. There was a small circuit board laying loose that may be the culprit. It only has 2 small contact points on it but doesn't seem to attach to anything. It is labeled "AWU7349" and "NE M PF2" and "BIND ASS'Y".
Sorry for the long description. Can anyone help?

I'm not sure what that could be but probably the amp. section. I have a xc-is21t, that came out in year 2000, I use it almost everyday, and it works excellent. Unfortunately a friend of mine has dropped the whole unit on the floor, and guess what it's still works perfectly, only problem the sliding door for the cd(but only the see thru plastic part) is broken and I'm not sure where can I find this part. I wrote a letter to, so hopefully they can locate the part for me. The only problem with this model that it doesn't play mp3 but again this was only made in year 2000.

Pioneer troubleshooting

Looks like a problem with the indication panel which is a fixed 'all-in-one' unit and probably needs a bit of soldering to rectify a few dry joints! More likely your very friendly repair man down the street will tell you he'll send off for a new unIt which he can replace for you at a 'smaLL' FEE!

Pioneer Elite vsx-27tx receiver with no bass!?

There may be a subwoofer mute function on your amp. The sub out is nothing more than a preamp output with a low frequency response. It is meant to be amplified by an external amp. Either check your powered subwoofer for operation or look through your operators manual for a sub mute function.

Computer beeps but doesn't start.

The beeps are an error code. Most times they are signifying a RAM or video card problem. With your explanation I would check the video card first. The card might have overheated or just plain crapped out on you. Try replacing and rebooting. Hopefully this will have fixed your problem. Sorry. Hope this points you in the right direction & Good luck.

Xc 600 stalling

when it stalls, is it on a warmer day? ie 20+ degrees? is it overeheating or hot? If you have never had the carbs serviced, the summer/fall may be a good time. inside the carbs, you have differnt circuits, they may be gummed up. Good luck
