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.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on. Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up. You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it. If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good. If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech. Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

SOURCE: I need to connect a pioneer amp m-L11 to a pioneer cd player xc L11 - which leads do I need?
It is verry simple to do (Karen) All you need is a (Audio) Patch cord, To connect it up to your amp.
