Audio Systems: Sony CDX-GT200 P Ant Output, sony cdx gt200, electric antenna

Question
Hi,

I had to disconnect the car's battery to replace a bearing on the alternator, but now when I play a CD the P Ant output goes off and the Power Amp switches off. However, if you turn to the tuner, then it switches back on, working fine.

How can I fix this?

Answer
the radio is wire wrong there is NO WAY this happend because the battery was unplug, the problem is that the amplifiers are wire to the power antenna output not the remote amplifier wire  blue wire not blue/white

when the radio is on it send power for the electric antenna
when the cd is playing there is no need for electric antenna and there is no power
