CTS 4200 not working

Recommended Posts

We have a CTS 4200 in our office and when we press the power button, it will come on for a second and then there is a clicking noise. After the clicking noise, the only light on is a blinking power light. It is connected to a power supply that is regulating/filtering the power so I know it is getting good power from it because there are other equipment attached to the power supply and they are working properly. Does anyone have any troubleshooting suggestions.

Hello and welcome to the forum,

The one thing I can think of is to disconnect all the signal and speaker cables from the amp an then turning it on, that would let us know if the problem is within the amp or outside of it. Other then that it will take a trip to the closest repair center :(

Verify the low voltage psu and confirm voltages: +15V, -15V and +5V. If all is good, then bring it to an authorized Crown service center.

The user manual does state that if a blinking power light is present, it may mean that the AC supply may be below a certain threshold. Make sure that you do have 120V (for North America) coming to the CTS.
