SOURCE: it keeps turning off

The audio output ICs or transistors are blown. Solid state elctronics are not very forgiving when they are shorted. it takes one tiny instantance and the componets will fry. sorry to be the bearer of bad news but you will need to have this unit serviced or replaced, And never ever work on any type of electronics with the power still on. Good Luck

SOURCE: unit turns itself off after diplaying code "check SP wire"

My guess, guess, check CLOSELY the SPeaker wires - "Check SP wire" make sure all of the bare portion of the wire is into the terminal. No bare wire touching another bare wire both at the receiver and at the speakers. Also, if the wiring is not continuous, check all connections of speaker wire. Disconnect all but one, play it like that. If no problem, label that as good, disconnect another for several days, when one shuts Rec. off, check wires closely for that speaker.

SOURCE: i tried hooking up an old polk sub to my yamaha rx-v659

If a fuse was blown, it likely would have no power. However if the power board has overheated, the capacitors may have swelled up and burnt out and will only allow it to power on for a few seconds, then shut down. The capacitors can look swelled up or burnt or have burn marks on the power circuit board. You can test them with a continuity meter. Each component has a printed number of it's voltage and ohm resistance so you can test them.

My john deere la125 seems to be drawing power wile shut down, it take a week for the batter to go dead, i've pulled the batterer and it stays charged up , I've checked the charging unit and i


What you do is power off the machine, and disconnect the negative battery cable. Put a test light or volt meter between the battery negative terminal and the disconnected negative battery cable.

You will likely have a light or voltage reading...Then you start disconnecting things....I suggest the alternator.

When you have the correct component disconnected and the test light or volt meter shows no current.

If this component is the alternator, they have diode sets inside (or somewhere else in the charging circuit) Typically one diode fails and this causes the draw that you describe. The system often still charges, but at a slightly lower capacity with the failed diode.

My computer is randomly shutting down. Sometimes it will work and other times it will not. I think the processor is overheating and causing it to unexpectedly shut down. the screen goes black, the power...


Few reason for the shut down
Could be heat, electrical,

1. try cleaning all vents with compress air in order to remore dust and fuzz that can be cloging the vents.
Once this done, verify that fans works proprelly,(check air flow coming out of vents) if they dont they will need to be replace or cleaned out.

2. Check power supply unit, and battery.
Sometime power supply unit is defective, getting too hot and power output is not stable and shuts down the laptop. ( change power supply unit) check if battery hold charge. if not change battery

3. Check connections for looseness and contact

If all seems normal,and none of the mentionned point seem to be defective, the cause is deeper and would need to be looked at by a technician.

Power surge caused wine cooler to quit cooling


Power surges, spike and brown-outs are a nemesis to small refrigeration units. The capacitor for the compressor likey was affected and possibly the start components in general, especially if the unit was operating when the surge occured.

I have the Panasonic over the range NNSD227B/W microwave - I started having problems with turning the light on under the microwave - button wasn't working. Now the whole microwave has shut down - No power...


Hi,
Unfortunately the unit will have to be opened up to check any further problems. If you can, check inside on the power circuit board for blown fuses or any other component which seems to be burnt. It's not always possible to see if a component is blown without testing it but the problem is almost certainly on the main power board.
Best wishes,

Unable to switch on. Have checked safety switch and fuse on home circuit board - OK Power on outside unit on and OK Remote control has new batteries and display OK Cleaned remote sensor panels on both...


as per the problem which you mentioned it clearly indicates that problem is with the switch in the wall unit.but you mentioned that you checked the switch and it is OK.
this means that the problem is with the main circuit control board of the wall unit.on that board the component is got blow-ned out or any of the component is got loose.you will have to check out with meter .if it looks looks then component needs re soldering but if its faulty or blow-ned out then that component needs replacement.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Wife removed rear cover, blew out dust, brushed lightly with toothbrush. Also removed round black cover on side releasing a spring and cam but seems to be put back correctly. When plugged into power outlet...


There may be a few solutions to you problem. it could be that the carbon brushes located at the left and right of the unit are either gone or improperly seated, as they will only work one way. part number for the brushes is 9706416 after checking these and if they are okay. i would check the board to see if there was any bending atall during the cleaning. there is a metal arm that the white actuator slides into on your board. if this metal arm has been bent even by a 1/4 inch or more it wont make contact and your unit will not operate.hope this helps

Thanks

Amplifier power light will not turn on. subwoofers will not work.


Recheck the fuse on the amp, if the fuse is good, try replacing it anyway, if that doesn't work your amp has blown an internal component, (most likely an output transistor). it is probably cheaper to replace the amp than repair it.

Right light comes on- but then shuts off trying to get to turn on


First, check your fuse, it really could be that simple. Check it with the Ohms setting on your DMM, do not bother with continuity. If it is under 1 the fuse is fine.

It actually sounds like a short in the amp circuit. Inspect the amplifier where it connects to the heat sink. Check for signs of oxidation or any contaminant that may cause a short in the amplifier. Ensure there is ample thermal grease between the amplifier and the heat sink. You may wish to reflow the 22 pin connection on the board. I would recommend desoldering the whole component if you can, cleaning and testing it, and resoldering to the board with fresh lead free solder and no clean flux.

If the amp is blown you can replace it for around $70 USD.

No Life, does NOT power up, Fuse is OK


There is apparently some component in the stanby circuit that is malfunctioning. There may be a milli amp fuse off the standy transformer secondary. Check - don't confuse with a resistor. It may read 2 ohms or less
