SOURCE: computer wont start, no signs of life, power supply is good and green light turs off when plugging into computer

Hi there
Sounds like a common problem
when you plug the power pack into the laptop its power light goes off because there is a fault. Most commonly this is connected with the plug or the socket into which it goes or the motherboard.
visually inspect the socket, if the central pin is loose thats your problem, if not then check the plug/jack bend the cable on it as these are prone to breaking. wiggle it around whilst checking the power button and status lights if none of that works then you need to strip the laptop and perform a continuity test on the first stage.
ie between socket and motherboard. please note for any sign of exposed cable and remember electricity hurts on contact be carefull. especially if you test motherboard for voltage.
ps the switch is pretty reliable and i would not poke anything in that hole just yet.

SOURCE: Monitor goes blank randomly

It is the capacitor on the power to the monitor. I have replaced about 5 so for. The capacitor is like 69 cents. Open it up and look at the circuit board where the power plugs into and see if any capacitor are bubbled up. If so then its a bad capacitor.

Ac electric works with generator but not when plugged in to 110 volt from the outside

I would be checking the main breakers on the panel to insure one didnt trip when you added generator electric. is there a breaker on the outside line at the box you may be missing? Also keep in mind, although uncommon, breakers do BREAK and need replacing. are you competent enough to use a volt meter to check the hot leads on the box and at your unit breaker box to insure you are getting power into the unit? In some older units the switch between land power and generator power was to manually throw breaker switches but automatic processors have replace them now... I would say start at the residential plug in and verify power is where it should be along the route of the supply cord...from the meter forward... if you have a converter plug, say from the 220V 30 amp that you are probably drawing down to 110V household, stick that on the meter and plug in your toaster to insure there is power coming in....IF YOU DONT HAVE A METER AVAILABLE... otherwise...test test test... your generator probably broke a circuit somewhere... now just to find it..

We have electricity to operate the microwave and plugs but the lights are operating off of the batteries. Is this a converter problem? If so is it a fuse on the converter? Doesn't appear the aux...

The microwave and outlets are on a 115-120vAC source running through the breakers box. The lights are 12vDC running through the converter then to the fuse panel. Locate the inverter in the compartments up front, possibly behind a panel that can slide or screws to hold the panel. Depending on the Mfr if the inverter, you should see a blade style buss fuse on the side, typically near the 12vDC output. Use a multimeter to check for the 120vAC input and 12vDC output. AC power-yes and DC power-no, check the fuse, replace if necessary. If the fuse is good, the inverter has blown and needs to be replaced. If you have AC & DC power on the inverter, go to the batteries and check for voltage without the inverter supplying power. Pull the fuse off the inverter or switch the battery disconnect switch. If the batteries have little to no voltage, cells may be dead. Take the batteries to a local auto parts store to get checked to see if the battery needs a charge or replacement.

On 1994 southwind motorhome rear ac unit clicks but fan doesnt blow but it lights up as unit is on

Check in your unit for a switch on side wall or near ceiling for selecting which AC unit gets power. Should be front, back, or both. Usually black knob to turn. Sounds like 12 volt power getting to it that tells it what to do, but also need to switch over to allow 120VAC power to actually supply power to it for running fan, compressor etc. Be sure to check all breakers in panel as well. You will probably not be able to run both at same time unless plugged in to 50amp or plugged in to 30amp, and generator running as well. I'm thinking a 94 only has 30amp power cable anyway.

What size power adapter does it use?

You need a AC to DC power supply capable of supplying 120VAC in, 12VDC out @ 1 amp (1000 mA). The center of the plug must be + and the outside -. I believe Dell supports these speakers and may have the power supply available. Radio Shack might have a substitute PS as well, you just have to match the plug size. Be careful what you pay for it, a new pair of these speakers can be purchased for around $20.

Here is a 12v 1500mA adapter (the mA rating can be higher that what you need, but not lower) from Radio Shack… but its more expensive that a new set of speakers.

I use a Dometic RM2193 in my pop-up camper. Can anyone tell me what temperature differential I should be able to acheive on 120VAC, propane and 12VDC? On 120VAC I was getting about a 40 degree fairenheit...

Usually from the Bottom of the refrigerator you should have minimum of 43f or colder than ambient. Should work very close to same on both gas and 110, on Dc it may not cool as good. From your description you may have an issue with ventilation. Cold air needs to flow in through the lower vent and out through the upper, if it cant, cooling efficiency is lost. Adding a fan kit can help on hot days. On gas you may have particles that fell down in the burner. Just take the cover off, take the burner screw out and blow down into burner to clean out. compressor or canned air works fine. If cleaning the burner doesn't improve it enough on gas to match electric you have to make sure your regulator on your rv has enough pressure... the fridges require 11 inches of water column.

Maytag Neptune FAV6800AWW Top Loader will not turn on. Power outlet is operable HELP

Hi Sandra,

I assume you have no LED’s lit when you raise and lower the washer lid or press a Wash Cycle or Spin Only cycle. This may not be an easy fix but this how I would proceed to troubleshoot.

From the machine schematic I see no fuses or circuit breakers in the machine that could cause loss of 120VAC distribution to the washer Control Board or other relay inputs. This is what I can tell from washer schematic. 120VAC comes into the machine passes thru and EMI filter is then distributed to the Control Board for +12VDC and +3.3VDC generation and 120VAC distribution to the main system relay, motor control board, drain pump, door locks/unlock solenoid and so on. I would start looking with my DVM to see if I had 120VAC at connector P6-1 the L1 (120VAC) input to the control board referenced to P6-3 or 4 the 120VAC neutral connection. If you have 120VAC at those points I would look to see if I had +12VDC power generated by the control board +12VDC power supply.

+12VDC could be measured at the Control Board Conn P3 Pin 3 or 4 referenced to Control Board common Conn P3 Pin 1. If there was no +12VDC generated by the Control Board I would replace the control Board and see if that restores normal operation. What I’m describing is the troubleshooting path I would take as an electronics technician. If you call in a repair service run my suggestion by them and see what they would suggest. I would make sure they bring out a Control Board for your machine. The Control Board has a 5 yr warranty. They will need your model number which you have and the serial number of your machine. The s/n is located on the back right side of the console. I will attach a couple links for reference. The Service Manual link has Maytag warranty contact info.

Let’s also see if another forum member can offer a solution to this issue that I may be overlooking.

The Service Manual for reference. Sears Parts Direct for reference.

Good luck and let us know if you have additional questions.

C32A26 crt TV; No audio or video

Mmm this is tricky - there is no normal transformer power supply in a tv. They usually just rectify the supply and regulate it for the circuits, and use voltage doublers and a transformer to get the EHT. Be carful the voltages can be 20,000volts! Check all the capacitors. The EHT flyback transformer can arc and present a clicking sound. Make sure everything is clean.

Converting the power to genertor

You should not have to switch between battery and generator, unless you are trying to use an inverter as well. Batteries are 12vdc, typically run lighting, water pump, furnace, fridge controls. Generator powers ac, microwave, television, and anything else that plugs into a 120vac wall outlet. Inverter may also run select loads, and possibly dedicated wall outlets, but not AC, fridge, or microwave (usually).

Most RVs / Motorhomes now have automatic transfer switches that will switch between the generator, shorepower, and possibly an inverter. Your coach is made during an era of transition from manual transfer switch (in form of heavy duty electrical outlet near shore power cord) and the automatic transfer switch.

There is no specific place where a transfer switch or generator receptacle are mounted on an RV. There are no rules or regulations tha cover this as far as I know. Your RV may also have an EMS (Energy Management System) that will control the transfer switch as well. EMS panels are typically located above the refrigerator or above driver / passenger seats in overhead compartment.

Won't work on ac

1. Make sure the AC power source is ok.
2. Make sure the AC power cord is good with no damage.
3. Look to see if there is a reset button on the rear of the set. If not, then look for a blown AC fuse inside the set.

Since the set works fine on +12VDC, the majority of the TV set is ok. You have a problem in the AC power supply. It could be a blown fuse, bad rectifier / regulator, bad step-down transformer.

The TV typically runs from +12VDC. The AC supply steps-down the 120VAC and rectifies it into +12VDC to power the TV. At some point in the TV, there is junction point where the +12VDC from the sets internal AC supply meets the external +12VDC power source. Usually they are electrically isolated from each other with a switch or with diodes.

Please let me know if I can be of further assistance to you.

Good luck!
