Check Power
Check the outlet by plugging an appliance into the same outlet the washer was plugged into an running the appliance a hair dryer works good for this it will draw some amperage. If it works fine move on.

To check the control remove the top panel and then remove the console to access the wiring to the control. Find the wire feeding the control from the main power cord. If you cannot visually see this refer to the tech sheet or service manual. Connect voltmeter to the 2 wires feeding the control if it is recieving power and it does not respond replace the control.

A le-24g90 tv sometimes display ok sometimes black, tested capacitors are ok, when black front panel seems to work fine

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a sumsung SMH9151s microwave that recently started having problems. Now it keeps beeping and in the display its going back and forth to the letter L and back to 0. I tried unplugging it and plugging...

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board.

My oven display dosent work nor the oven itself it justs beeps and then nothing

The membrane or main board has failed most likely. the display itself is built in the board...the beep usually follows some sort of fault code...its possible your having a voltage problem, like a burnt wire on L1 or L2 at the junction box or inside the oven itself. This is not easy to trouble shoot with limited info, but hope this gives you a general idea of what to look for...Bruce Denton

It does not start up and have already replaced the control board

Beffore the control board was replaced it was important to check that the power supply was correct. Hope the secondary/main transformer is working.if supply is not coming to the main board check the fuse and this sub transformer.
A check will indicate that the line is correct and the power comes to the board. If the board is not acitve then the front panel touch board could be faulty. Also check the main capacitor for the magnetron to function or the magnetron itself..
Hope you try this out.

U-61 is a hardware error code. Usually means main board failure, however have found that a bad changer can also trigger that code since it connects directly to the main board.

Emerson Microwave stopped working

Have 1 of 2 choices, the main fuse or the control board for the front switches and clock. primary of the small power transformer has opened. Unplug the unit and take case off and measure the fuse with an ohm meter. if u read 1 ohm or less then fuse is good. then measure across the main power plug tips. If read open then the power transformer is bad. Need to replace the board as not sure if transformer is available.
