SOURCE: I own an Pioneer CD

On the first board (where the power enters) there is a tall 3 pronged switch, if you turn the board over and solder a piece of wire to the 2 outside prongs, you will find that the Amp works normally apart from that the display reads Cd closed when in Cd mode.

SOURCE: My pioneer vsx-519V-k amp won't turn on. Just

Have you checked within the set, the fuse and if the standby circuit is working. thre could be a failure of this sub votage which is required for the switch on of the main power. If you do not have any standby indication you must check this section, however if you arre getting the standby you would have a failed output or a shorting that is triggering the error amp to swtich off. If you are familiar with the circuits you can check but I would suggest that since you will need more experience to look into the main board for tracing the fault. In such case check for the service centre nearest to the place you are in using a google search for Pioneer - Audio systems- sevice. Helpful I hope. Good day.

No power to amp

Check fuses on the amplifier's power wire to make sure it's not blown. Replace it if necessary. Also check for blown fuses on the amplifier itself. The problem could also be the amplifier's remote wire. This wire (Usually blue) needs to be wired into the stereo's power wire (usually red or yellow).

Protection light keeps coming on

Check the wiring between the sub and the amplifier. That's seems to be the only thing left that could cause a problem. If it's shorted to ground or pinched so the conductors are shorted together, it could cause the symptoms you listed.

Directed 2400 amplifier turned off and has not come back on?

Hi, Based on your post/description, three possible reasons: 1. There is no power going into the amp. The fuses may be good but there is no +12VDC in the big red wire. You have to use a voltmeter to check if there is 12V at the end of the line/wire before it goes inside the amp. In some cases, the fuse might be good but there is corrosion on the fuse terminals and the metal contacts of where it is placed; 2. There is no switching signal to activate/power on the amp. In some setup this is a blue, yellow or orange wire. This can be activated by either the ignition switch of your car, the headunit/stereo, or even a manual on/off switch. This has to receive a 12V also to activate the amp; 3. Internal fault of the amp. The big red wire has 12V, the fuses are good, there is signal 12v to activate amp, but still no power; there is something wrong inside the amplifier. It has to be opened up and diagnosed. This may involve component level repair, circuit analysis, electronics and soldering so you might be better off seeking the services of a qualified professional. Hope this gives you some ideas and work out for you. Good luck and pls post back how things turn up. Kind regards.
