No Output from amp, green LED on

The amp is receiving power, i tested it with my VOM. My RCA's are brand new, and i tested them. They are plugged in the right places. My Green LED is on. The Amp used to work then just stopped giving me any output. I tested my subs, and they are good too. Can i repair this?

Are you absolutely certain your subs are in good shape? have you put a meter on them and measured the ohms as you depress the cone [causing the cone to move up and down on the pole of the magnet? do the ohms stay constant? go up to infinity[ suggesting an open] or go to zero or close to zero [ suggestting a short] both of these conditions will result in a zero or a very limited output from your amplifier, while still showing a green status light, if or when a full short or open occurs on the subs, a fault led will become lit, and whet that means is that u have fried the a bit more testing with your vom....and good luck or try another speaker for testing purposes...

LED lights up but! ???

Sounds like there is a problem with the amp. Try switching the inputs around for that output on the amp. If that does not help, Yes I would have to say that there is a problem with the amp output circuit.

Looking for manual for pioneer sw200 powered subwoofer

Most subwoofer have a left and right phono/RCA sockets. The amp should have a sub out phono/RCA plug. The sub should have come with a phono/RCA lead that will connect these - one plug to two plugs.
Apart from the mains plug that's all there is really. You may have to switch the sub socket on the amp on.

Or you can get one of the cables from places like below:

Got this amp from a friend and want to wire it up to my Sony head unit. The HU does have pre-out in RCA plugs. please help. I have tried it with: RED - stereo Amp Rem In YELLOW - 12V BLACK - -12V...

Red- 12 volts switched (ignition)
Yellow- 12 volts constant
Black- Ground
Blue/white stripe- remote amp turn on/ power antenna
If you have any orange wires there for the Illumination dimmer. (head unit dims when you turn the lights on). The white and gray are front speakers and purple and green are for the rear, solid being + and black striped being -. (gray and purple are right channels)Make sure that the RCA plugs go to the input side of the amp. I hope this helps, Ray

Hum sound when plug in. if i touch the input jack the hum sound disapear.

The best way to test your sound problem is to buy another pair of patch cables/RCA cables and try those, most likely you have a ground loop in the RCA cables, basically you are creating a ground when you touch it.

I have a kdc-mp435u and when i connect the subs woofers to it,it dissent put out enough out put Signal to it and when im driving some times it give signal the woofers cussing them to hit heartier. I check...

did you plug your rca signal wires into the subwoofer ouput rca's? if so you can control the level and frequency of the sub on the face in the audio menu. if this is not the issue try new rca cables. you can run them outside the car first just to test. another issue is make sure you have proper grounding on the head unit and amp. also if your rca cables acccidently touch power they can blow a fuse or trace inside the radio causing the rca's to lose ground (you will have low audio with lots of humming noise). you can check this by jumpering a small wire from the radio frame to the outer shield of the rca jack while it is all plugged in. if the sound gets louder and cleaner you can secure this wire in place by soldering it or fixing the circuit board itself.

I have a Bosch oven model HBN58066OB. It was used in an exhibition and de-commisioned. The element wires were disconnected for safety reasons and then re-connected. I think the wires are connected...

Step 1: If the oven element doesn't work, first check to see if the range is receiving power. Don't overlook the fusing system inside the range.

Step 2: If the range is receiving power, set the timer on the range to the MANUAL position.

Step 3: If the element still doesn't heat, turn off the power to the range and test it with a VOM set to the RX1 scale. 

Step 4: Remove the screws or plugs that connect the element to the power. Remove the retaining shield, which is usually held by two screws, and remove the element from the brackets that hold it in the oven. The element is usually held in these brackets by screws. 


Step 5: Clip the probes of the VOM to each element terminal. If the element is in working order, the meter will read from 15 to 30 ohms. If the meter reads higher than 30 ohms, the element is faulty and should be replaced. If the element tests all right but doesn't work, the problem may be at the terminals. Make sure the terminals are clean and tight at the element connections.

Oven and broiler elements cannot be tested without a VOM. If you don't have a VOM, take the element to a professional service person for testing. The problem is usually a malfunctioning element; however, you aren't risking much by replacing the element without a professional test.
