Question about Audio Players & Recorders

Open Question

I have a Mission 700ASi subwoofer. It's blowing fuses and I've found that one of the capacitors is leaking and bulged. I'd like to replace it but the covering on the side that has the value has cracked and peeled off. I'm not sure what value capacitor to replace it with. Can I get a schematic that shows the capictor value? Or does anyone with experiece with the Mission 700ASi know the capacitor value at location C10? Thanks, Steve

SOURCE: StR-DE945 stuck in auto protect mode

determin if the speakers are at fault first. un-hook them and turn on the unit if it stays on one of the speakers is bad. if it remains in protect, the output transistors are shorted. there are a pair for each output. they are located on the large heatsink in the center of the unit.

SOURCE: LCD Monitor is black... blowing transistors

Bulging or "blown" electrolytic capacitors are a common problem with LCD monitors. If you replaced them with correct parts (voltage rating) then one of two situations comes to mind:
1. Electrolytic caps are polarized, if you install them backwards they will blow quickly.
2. The voltage the circuit provides exceeds the rating of the cap. A 5 volt cap in a 12 volt circuit will blow quickly. The voltage regulation circuit may not be working.

SOURCE: Kenwood KR-A4070 blowing 5a 125v fuses

I am guessing that the ceramic resistor is close to the output transistors. I would also guess that one or more of the output transistors has shorted. This causes a high current draw that is blowing the fuse. You could also have a power supply problem. The ceramic resistor is a .22ohm dual emitter resistor that is used in the output stage. The transistors located close by are probably shorted and should be replaced. Start there and let us know what happens once the transistors and the resistor are changed.

SOURCE: X2GEN CAPACITOR LOCATION

I had the same problem with my 22" X2Gen, first the monitor started what looked like a random color temperature shift, ie the screen would switch between a yellowish and blueish tint, then it wouldn't turn on and the amber standy by light flashed on and off. I took it apart and replaced the 2 220uF25V capicators with 2 220uF35V caps I got at radio shack, part number 272-1029. Don't worry about the voltage mismatch I'm pretty sure it doesn't matter, the voltage is the maximum the cap can withstand and has nothing to do with the voltage in the circuit. The caps are located on the board that the AC cord plugs directly into, it has a plastic (almost feels like paper) sheild, the caps are marked C812 and C813 on the circuit board. There was no 47uF35V cap that I could find, anyway replacing the two did the trick, all for under $3, I almost went out and bought a new monitor ;) Hope that helps.

SOURCE: blown fuse in mission 700as subwoofer

if you have access to a multimeter, you should test you impedance (ohms) Ω, check to make sure the speakers reads higher than the amplifier needs; this will result in less strain on your amp and diminishement of sound...For example: if you connect two 4Ω
speakers in series it results an 8Ω circuit (least strain). and if you'd take the same two speakers and connect them in parralelle it would result in a 2Ω circuit (most strain).

No power. Fuse was blown but replaced fuse and still no power.


If fuses blown there is a case to search for short circuited active parts examples are end-transistors caused by clipping speakers cable shorts leaking or convexed capacitors but any new fuse will blowing again and again also the bridge rectifier to make dc voltage inside the power supply of the subwoofer can caused this problem

I have a mother board i use to replace the fuse but it always exploding


A fuse is meant to blow before a component blows as a safety mechanism. If it's constantly blowing that means you have a short somewhere. Check the capacitors for obvious bulging or leaks and replace anything that looks like it's shorting. If you can't figure it out you need a new motherboard

Bad capacitor(s). Happened to mine too. Opened it up to find 2 completely blown apart, and 1 bulging. Relatively cheap and easy to replace.

You should look at the circuit board for the power amplifier and check for any leaking or bulged electrolytic capacitors. If this speaker uses the circuit boards made by AMI (such as most JBL and Mission sub woofers around 1999-2001 vintage) they had a lot of problems with this as well as bad modules. Google for the module S53AMI and you will find lots of info if this is what you have in that Athena.

It is actually a 1.25A SB (for "slow blow") fuse. You can buy these at most any electronics parts source such as Sayal Electronics or Active. If the fuse is blowing though, there is likely another problem causing it to go. The electrolytic capacitors on the main amplifier board are prone to drying out and shorting so check them before you put a new fuse in. Look for signs of bulging on C10 or evidence of any excessive heat anywhere such as burnt looking parts.

Mission m-cube sub fuse keeps blowing


If you have replaced with the correct rating and the fuse blows off then you will need to check for higher current drain in the sub woofer or the network. After replacing the fuse load up the subwoofer slowly, reduce the bass and as you increase check at the point the fuse blows off. Now we need to analyse if the rating of the amplifier you are using is rated for the subwoofer. If your subwoofer has a higher rating you can increase the rating by about 25% and check again. Some amplifiers give a very higher voltage on full bass which could result in such a condition. Moderate this and check again. If the fuse stays Ok you can continue with this new rating.Otherwise the output of the amp at higher volume needs a confirmation. Hope this helps. Good day

My Mission MS10 subwoofer keeps blowing it's fuse. Possible problems?


Anything in the power supply will cause it, look for damage or burnt parts, anything on heatsink. A transistor with a short circuit. For instance if you put an ohm meter probe to the leg of one and the other probe on to another leg, it will be read on the meter as if you had put your probes on the same leg.

AR1 Subwoofer Keeps Blowing the 5 Amp Fuse


Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).

Subwoofer eating fuses.


Check the circiut board for any blown capacitors. Sometimes it's that simple as replacing a capacitor. But then again, what is causing the capacitor to blow??/ Hope this helps.
