Caution: even if you have the part to replace it be sure that you know what you're doing. Check for dc voltage at the output line before even connecting/soldering the power transistors. You might fry it again if you don't. hope this helps.

Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.



Hope this will help to fix the problem.....

How do I get my Maytag Neptune TL washer to stop beeping and start washing again ?


Try disconnecting the 120VAC power cord for a few minutes then re-power back up if you haven?t already tried that. If you still have the same issue then you may have a failed Control Board. If it?s the FAV6800AW is there an error code in the LED display? If the machine will not d let you into Service Mode then my next step would be to replace the Control Board a 10 minute job. If you decide to call in a service repair company I would call Maytag for an authorized Maytag repair service in your area. Some parts like the Control Board may still be under warranty (5yr). Warranty info is in the SM link I attached. The number to call is 800-688-9900. Maytag will need your model number and serial number, that info is located on the back right top side of the console. The Service Manual for reference. Sears Parts Direct for reference. Post back if you have questions or want to dig deeper into the issue

Dryer turns on but no heat, I don't have the manual so not sure about how it works, there is a swicth that says "air fluff, heated dry & timed cycles" I have tried turning this but nothing happens.


try flipping you breaker off and on 2 or 3 times (hard and fast) if this don't work check element, timer , thermostats and safety switch on motor (check wiring diagram for pin numbers of safety switch)....if this switch goes bad the motor will still run but it wont let power go to element

Worked one night, next morning would flash on then automatically turn off


Yep, the inverter transformer on the Power Supply Board burned out. It's one of 5 inverters that powers up the screen.
If one is burned out, it will not have enough juice to power the screen and goes into protection mode like it's doing right now.

You'll have to replace the POWER SUPPLY/BACKLIGHT INVERTER BOARD. The cheapest place runs for about $90.

I'm not sure which one you have, there are 2 different boards for that TV. The board number should be in white on your board.
Here's for the BA8AF0F01031
http://www.shopjimmy.com/power-supply-backlight-inverter-ba8af0f01031-from-emerson-lc320em9-5.htm
And here's for the BA8AF0F01032
http://www.shopjimmy.com/power-supply-backlight-inverter-ba8af0f01032-from-emerson-lc320em93-8.htm

It's definitely cheaper than buyig a new TV. That what I did to fix mine. :)
If you throw your old board in the trash, I would like to keep it for research if possible. Here's my e-mail: dsacco86@hotmail.com

Flashing f 06


drop the bottom panel by removing the 3 screws on the bottom, pull down and off. On the right side attached to the bottom of the door switch (on the inside) is a teardrop release tab. Pull down on it and the door will open. The F06 code is a motor tachometer error. The control is unable to detect the motor speed. While you have the panel off, check the harness that goes from the motor to the motor control board. The motor control board is the one on the bottom. Reseat the harness's for a good connection. If you can use a meter, check the motor windings, pins 1 to 2, 2 to 3 and 1 to 3 should read approx 6 ohms. Next, take the top off the washer by removing the 3 screws in back and sliding the top off toward the back. The main control board is in back. Make sure all the harness's are seated good. The third harnes from the right is the motor control power, re-seat it. On the left side of the board, last harness toward the back is the serial communication link. Re-seat it. On the motor control board on the bottom the communication link is the one toward the bottom, the center one is the motor connector and the top one is the power supply. If this doesn't solve the problem and your motor ohms out. I would tend to believe that the motor control board is the problem

Sub hook up to PPI D3000 amp


I'm not familiar with this amplifier but in most cases, if a mono amp has more than one positive speaker terminal and more than one negative speaker terminal, the positives are directly connected and the negatives are directly connected. So  as long as you connect the speaker positive to a positive speaker terminal of the amp and the speaker negative to a negative speaker terminal of the amp, it will work properly.
