You have a bad power supply (AC adapter). Watch closely at the red light while turning tv on to see if red light momentarily flashes green, then back to red.

My LG front load washing machine, model WM3001HWA, has no power. What can I do?


Hello Kyle;

My name is Peter. I am a retired field service appliance technician.

You have 3 sensors in your unit, a thermal sensor, a position sensor and a door lock switch. These components will prevent you from running but, would not affect your power.

I assume you checked your circuit breaker to make sure you have power to your washing machine.

The slightest change in power supply, electrical power surge or power outage will knock out your boards. Magnetic fields and static electricity will knock out your boards. Are your appliances near a main power supply line in your home?

All appliance manufacturers recommend surge protectors if you have control boards in your appliance. Individual wall socket surge protectors cost about $20.00 at your local Home Depot or where ever. This is a good investment.

Ok, your have 3 control boards in your unit. One is the digital display board which has nothing to due with power supply.

The others are your main control board and your control panel board. Each of which can turn off power. The highest probability is the main control board. The part number for this board is EBR 44289820. The part cost $225.00 locally. You can probably get it for $180.00 if you search the internet. This is item A450 on the following link.

Remember static electricity can not out a board. Ground yourself by rubbing your hands over something that is steel. Either unplug your unit or turn the power off at your household fuse box. There are several clips holding the board in the casing. you must push outward to remove the board. Inspect the circuit back side for burn marks. If there are no burn marks you can still have a board component failure. DO NOT DISCONNECT ANY CONNECTOR PLUG IN. When you replace the board, you will replace one at a time.

I have a panasonic plasma tv model TH42pZ80u series i think. as soon as i switch it on all the electricity on my house top floor switches off from the main electricity socket. dont know what to do!


There is a direct short circuit inside the power outlet, or in the mains cord of the TV. Switch off and remove the plug of the TV and just switch on the power outlet to make sure whether that is the culprit. If you have a multimeter, test the TV cord pins for short between phase and neutral and earth. If you notice short, this may need attention by a qualified service technician.

My rca truflat 27f520t27'' tv keeps turning off and all


There is some shorted component/s on the main power supply regulator baord to your TV. Work with main power board circuit is fatal to any inexperienced person, as 80% of the components at this stage will be Hot [electrically], when the set is switched ON. Without switch it ON, you cant check the voltages at this section. S, if you are not experienced to do this work, contact any experienced service technician to get this set repaired.

The garage door open with remote will not close with remote usless you stand under the main opener


Limited range of your remote controls could be related to radio frequency interference that comes from something in your home or in the surrounding environment. Certain electrical devices can radiate interference; this could be almost anything that is plugged into an electrical outlet.

Please keep in mind that the device can be brand new, or can be an item that has been in use for quite a while. Also, the item may continue to function properly as far as you are able to tell. The only problem with the item may be that it has started to broadcast the interference, with no other symptoms noted.

Some devices are more likely to generate interference than others. This includes TV cable, cable amplifiers, surge protectors, fluorescent lights, battery charging devices (power tools, golf carts, etc.), anything that utilizes a timer (sprinkler systems, lights, alarm systems, etc.), and a myriad of others. If the problem seems sporadic, we can safely assume that the device responsible for the interference is only being operated during these times. Again, please keep in mind that the age of the device does not determine if it is capable of broadcasting unwanted interference. Any electrical device can be the source of the problem.

To isolate potential sources of interference, turn the circuit breaker off to the garage and plug the garage door opener into an extension cord from another room. If the range improves, then the interference is coming from a device in the garage. If no improvement is seen follow the same procedure, this time turning off the circuit breakers to your home, with the exception of the garage and test the remote controls. If improvement is noted, turn the circuit breakers back on, one by one, until the range problem resurfaces. This will allow you to narrow down what room the problem device is in. You will have to go from there to isolate it further, by unplugging and re-plugging the items in that room.

If you are unable to determine any source of interference, then the receiver logic board in the overhead unit will need to be replaced.

I replaced both three way switches in my hall way. They worked great for about 5 tries. After that one works great and the other only turns it of and wont turn it back on. Its an old house and has 3 wires...


If you are certain that both switches worked correctly at first (you could turn the light on or off from either switch with the other switch in either position) then you have a bad switch. But if you aren't certain of this, it is likely that you wired one or both switches incorrectly. There are lots of great write-ups to be found if your google - how to wire a three ways switch --- But I like this one. http://home.howstuffworks.com/three-way2.htm

Tv turns on and off


My JVC 35 " AV 35750 toggled on/off non-stop too.

Fix for me: Unplug TV. Trace cables from on/off switch to main circuit board. I unplugged the cable at that point to eliminate the the on/off button and remote control sensor. Applied power to the TV and my TV stopped cycling on/off so I figured the problem was probably not on the main circuit board but with the push button/ remote control sensor board. I again removed power from the TV and plugged the cable back in to the main circuit board. I then applied power back to my TV to verify my symptom, but when I did this, the TV worked fine again.

Many times resetting circuit board connectors will clear electrical problems.
