Re: Samsung washing machine no power to discharge pump
Just to give an Update....I had to bail on the repair for several reasons, further inspection of the machine found worn shocks, excessive play in the shaft bearings and something is broken off between the drum and the tub and floating/rubbing on occasion. The back of the original board showed more burned areas then the front. The cost in parts alone was more then the new machine. So, I bought a new machine and it wasn't a samsung.

Re: Samsung washing machine no power to discharge pump
I have extracted the donor board from the plastic housing, however it is still encased in silicone.But at least I know how to get the other board out without damaging it.
I can trace it out, I also have the schematic (it's in the service manual) and can solder use a DVOM have a scope, esr meter and more.
The pump is small (fist sized) 120v pump with no capacitor on it. The pump runs fine with 120v connected to it. The voltage from the board at the pump fluctuates from approx 12v...Leave a comment:

Samsung washing machine no power to discharge pump
Model WF328AAW/Xaa. Original problem is the machine will not discharge the water. No power to the pump, I can run the pump off 120v, The circuit board is encased in what looks like silicone. The look to be some scorching on the board in a couple spots.
I have ordered what is supposed to be the replacement main controller board as per the parts people at several . I had to source it via ebay as my orders with reputable online suppliers were cancelled do to the part being NLA.
Both replacement boards were listed as NEW, both boxes were beat to death in the mail. Both... -

Re: Element ELEFT436 will not power on
Yes there is 12v, I failed to see anything marked 5v to test, But did have a 5v reading if you look at the chart.
I also attached pics of the front and back of the board. Tell me where to test and I will....Leave a comment:

Element ELEFT436 will not power on
This tv has the red light on. When I hit the power button nothing happens. All the caps look good. Want to make sure it is the main board and not something else before I order the part.
What pins can I jump out to power it on? -
Re: Vizio e601i has no backlight
The led strips have been replaced. Found that one of the 2 strips had a couple of leds that you could see were burned out.
To dis assemble the panel, once the back of the tv is removed, start with the screen facing you. This will aid in aligning all the diffusers on reassembly.
Have someone help you with the glass and have a brand new dust cloth to remove any dust that may get on the surfaces....I used one made by Guardsman.Leave a comment:
