First of all, WEIRD. what kind of power lines, the realy big ones that are a hundred feet tall of the normal ones that go to your house? if its the big ones, most radios experience some issues with this, but if its actually shorts out your radio and makes it turn off (not just static problems) then i would say that there would be a wiring problem with the way the radio was hooked up, or something inside of the radio is not working properly (in which case i have no idea...not a radio tech...just a mechanic). could check the antenna cable and make sure that all the wires going to it are in good condition = not frayed or anthying.Hope this gives you some direction and some basis on where to start trouble shooting....good luck...

AM FM radio Compact Disc player o.k. for 30 sec after start, then nothing. Fuses o.k.


Maybe a shorted speaker causing the power amplifier inside the radio to shut down or a speaker wire shorted to chassis and last the internal amplifier of the radio cd set faulty by itself... set volume to zero power it off take out the radio cd set; remove the speaker iso plug leaving the power plug only in and power it on if necesary turn again the volume down to zero and wait if it keeps turned on it a speaker problem if it shut itself off again then you go for a repair or a new one

I have short circuited the power cords to the cd player, the cd player and the screen is dead, the fuses in the fuse box under the steering wheel is ok. What have i broken?, can it be other fuses?


If you shorted out the power line to the radio and the power line did not have an inline fuse then the radio is probably toast. All after market radios have an inline fuse built on the power line so I'd check that first. also, some radios have a fuse that plugs into the back of them, you'll have to remove the radio to see that one.

MY RADIO AND CD PLAYER DISPLAYS SHOWS TO BE WORKING, HOWEVER THERE IS NO SOUND. THE FUSE BOX FUSES ARE ALL GOOD. THE SPEAKER WIRES ARE ALL CONNECTED. WHAT COULD POSSIBLY BE THE PROBLEM.


Some high-power players have an internal fuse in line with the speakers so that an external short will not blow the output transistors. Have someone skilled look for this.

Also, check that your speakers are not wired backwards; some speakers will connect one side of the voice coil to ground. If you connect the hot side of your CD player to the ground side of the speaker, you kill the sound.
