Hi Larry, sounds to me like you may have popped a diode likely due to inverting your power connections and yes, the older we get, the harder it is for us to deal with surface mount stuff which gets smaller by the minute it seems.... hi, hi! Anyway, that is what I would check for 1st is a popped diode..... hope this helps!

Hi Jack , little pun. the radio should come on no matter what. Take the radio ( no coax ) plug it into the wall ,now see if it comes on. Look in the back to see if its on AC or DC. Which ever way it is turn it the other way. If the radio doesn't come on you should open the radio and look to where the power cord come in for DC. there is a diode there called a reverse polarity diode. It is probably a 1n4003 but check it anyway to see if its burnt. If it is replace it and the radio should come on . Also check the fuse .

On my 2012 chevy impala,i took out my radio,which worked.i took it out because my 2yr old put change in the cd player,to get that to work again.i got the change out easily,but when I installed the radio...

u may have blown the fuse when u took the radio out look under your steering wheel open up the fuse box and pull the radio fuse it should be a 10 amp fuse u can tell if the fuse is shot if the wire in the middle of tthe 2 prongs looks to be fried if its fried u will have to go buy a 10 amp fuse at your local auto parts store they are very cheap and easy to install good luck

It will not turn on, took it to a Radio Shack just now and he could not get it to come on either.

Probably a burned out fuse on the power cord. Unscrew the end of the 12v plug and check the fuse with an OHM meter or just replace the fuse. Check that you have 12volts at the gps end of the cord.

Need to install a cdplayer in 70 chevy truck?

Because of the year of the truck you will not have any wires pre-wired in the truck, go to a Radio Shack, car audio store or Best buy and buy yourself some speaker wire for vehicles, about 5 ft of 14 - 16 gauge yellow wire, 5 ft of 14 - 16 gauge red wire a couple of 10 amp fuses and 5ft of 4 gauge black wire.

You are going to run the Yellow, Red, Black wires together from the radio space where the radio sits in down to your steering column, the speaker wires will go to your speakers from the radio, a + and a - lead to your speakers and connect them as needed.

Now back under your dash you will connect the yellow wire from the radio to the 12 volt + wire under your steering columns 12 volt power wire with a fuse inline, if you hook up a test light to this wire it will light up the test light without the car switch being turned on, the red wire will hook up to your ignition switch wire and your balck wire to the vehicles ground chassis, basically ground that wire to a non painted surface of the vehicle. This radio needs to be hardwired like I explained.

Good luck and hope it helps.

Panasonic ct-32sl13g blowing fuse by power supply

You will need to remove the back of the TV. Don't worry, it's not that bad.

There are 4 screws across the top, one on each side, one right next to where the power cord goes into the back of the case, and the two more by all of the video connections **These are the most important to remove because they attach the main board to the back of the case.

Once you have remove the screws then the entire back of the set will slide off. If you look where the power cord attaches to the board you will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four pack costs between $3 and $5.

Make sure that you check that it works before putting it all back together. Check for any loose connection cables while you're back there. I found a few when I did this.

Good luck!

Kicker zx 400.1 amp no power.. is it fried?

Well Friend, the chances that your amplifier is Fried are very low. First of all deactivate the Auto Turn On Feature on the Amplifier. Second, check that the voltage is received at the Power connector of the Lead that is coming from the Battery using the Multimeter to make sure that the Main Fuse is all right. If No Go, then check the Amplifiers fuses thoroughly. Then check if the Protection LED is lit. If it does not work after all of it, get it checked at any local radio shack as I'm sure, it cannot get fried just like that, as it is possible that some internal connection has fried or became loose and will be fixed without spending much. I wish it will help you..

JBL Eon 15 Blown Fuse

These fuses are most likely 3 Amp fuses. Please note that if the replacements blow as well, that there is a problem within the amp section that will require repair.

This sight rocks! And so do the people that posted information! Went to Radio Shack and got the 6.3amp 250 volt fuse. Fuse was easy to get to once I removed all of the screws and easily slid off the back. $2.99 fix (foe the fuses)
