Blows fuse when power turned on.

I bought this Phoenix Gold MX 1250 at an auction. Every time I turn the power on it blows a fuse. Sent it to Radio Shack and they couldn't fix it. Anyone got any ideas?

Ours did the same thing after about 3 months. Found out there is a thermal fuse in the red power wire in the base of the unit. It's visible after taking off the bottom cover. Just follow the red wire from where the power cord plugs in until you see a 'bump' in it covered by a clear tube. This is the fuse. We contacted Maxi-Matic and they said they have had problems with this fuse blowing and did not know the cause at the time. When it 'blows' (internally), the power circuit is opened, thus your unit will not power back on. They sent us a new one for free as ours was still under warranty. Their P/N is TF128C. We really use our unit a lot and didn't want to wait for it to arrive, so I went to Radio Shack and bought the same sized thermal fuse from them and put it in. Their P/N is 270-1322 and was less than $2. Since then we have not had any power problems. I am guessing they got a bad batch of thermal fuses from their supplier.

My Phoenix Gold MX 1230 12 channel amplifier 4 mode buss system keeps blowing the power fuse.

When any amp blows the fuse like this suspect an overload in either the power supply or main amp sections. Most likely caused by a sem-conductor that is acting like a piece of wire. Chances are it will be one or more transistors on the heat sink that's gone.

Fuse blows constantly !Power light on ? Thanks

Possible that the audio output section is short . remove speakers and fix in the fuse to test, if itt blows out the fault must be confirmed by opening of the amp and disconnection of the power output driver.If teh fuse then stays the fault is confirmed. replace and test the speakers in this section before connecting.

Im a trucker so when i plug my power wire the fuse blow why

You probably plug it in backwards at some point. When you do that you blow the polarity protection diodes. They are so you do not blow the radio.

Get a N14003 diode from radio shack.

Open the radio's bottom cover where the speaker is. Watch the speaker wires.

Near the back right of the board where the power cord plugs in left of the transformer, look for D23. Its the same diode as the one you bought from radio shack. It is most likely burnt.

Remove that one and replace with a new one.

The radio should work fine now. Be careful when plugging that thing in.

It used to cut out for no more than 15 minutes, i thought due to a heat switch. Now it cuts out for a couple hours or even days at a time

suonds like the amp is overheating, try turning the peak knob down about 1/4 turn and turn it on and see if it still does it, also see if the fan kicks in, if not that is normally easy to fix. any auto sound system store will have the replacement fan for it. if not take the fan out of it and take it to a radio shack, I know you are going to say " BUT IT IS A RADIO SHACK PART" well the main thing you pay for with everything is the names. the parts are all made over seas and are shipped here on the same container ships, all electronic parts are the same, all you are paying for is the name pioneer, sony, octain etc. they are all the same parts.... hope this will help you.

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!

PC power supply fuse - T6.3h 250v engraved on end

T = time delay (slow blow)
6.3A = 6.3 Amperes maximum load
H = HRC - high rupture current (as you specified a ceramic fuse)
250V = 250V AC rated

other letters you may see
FF = ultra fast blow
F = fast blow
M = medium blow
TT = very slow blow
L = low blow current
H = high blow current (glass package)
S = sand filled
