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.

Power fuse blows when you push power button


Hello
You haven't specified anything about the description [brand name, model number etc] of your TV here. Anyway, if the power fuse blows instantaniously as you switch ON the set, no doubt that, there is some dead short circuit in the power regulator board of your TV. Never put no more fuse or switch ON the set until this fault has been retified. Sometimes there will be some bulged of shorted capacitors in the power sully regulator bard of your tV. Check for it. I'm herewith attaches the picture of a power supply board of Tv, [not with your's;] for you to identify what a bulged capacitor will be. If there is such capacitors on your TV's power supply baord, just repalce it with same size and capacity. Its capacity will be marked on it. gopakumarg43_51.jpg
See the bulged capacitors, marked with red arrow. You can see a good one, on the top right part of the board with flat top. You haven't given anymore details of your TV here with your problem post. So I could only give you this much information and repair tips. If you want any more assistance from me, feel free to get me by FixYa. OK.

What problem would make the screen go black with vertical rows of hash mark down each side of screen?


ael 16504, If unit performs in same manner when connected to a "Known-Good" pc, then unit may need to have the internal power supply board (SMPS/inverter) checked out by you or qualified monitor technician. What is "date of manufacture" and model number? Have you seen any repair videos at YOUTUBE yet??? Was monitor working good 24 hours ago? Will your pc perform perfectly with a different monitor connected to it? When very "strange" stuff starts to occur with CCFL lcd monitors, the very first place this tech will look is at the SMPS/INVERTER power supply board. Do your research here in the fixya profiles of "budmrtn" "buddymc" 12fixlouie"(me) and at YOUTUBE for video clips of monitor power supply board repair (bad capacitors)

Most LCD monitor manufacturer do not make their own Power supply/Inverter board, you need to get the name and number of the board and search on line. You can also have more than one version of the power supply for the same model.
