OUR LG MJ 50HL2 MICROWAVE OVEN IN NOT WORKING,NOT GETTING POWER

The Electronics panel can be replaced. It is highly likely that the rest of the parts still function ok.
But NOT BY YOU unless you are a qualified person to carry that out!

Microwave oven voltages are LETHAL ! Touch the wrong place while live with the power on, by accident, and it will be goodbye.

You can find a second hand working one on Gumtree.com for a reasonable price.

If the microwave buttons don't work the touchpad and control panel assembly are probably defective.

With Power on Microwave There is Light Blinking It Means Is Normal Power Supply Supply Problem,Not Reaching Front Panel Power Supply

a problem with the control card that controls the functioning of the microwave

To do this you have to remove the casing of the oven to get access to the bulb & I would NOT advise you to do this unless you are qualified in electrics. Microwave ovens are very dangerous pieces of equipment to deal with even when unplugged from the power source. A competent engineer should be able to quickly fix this for a reasonably acceptable price.

The magnetron probably has a partial short pulling more current than normal as it runs, the other two items that give trouble is the high voltage diode, "sometimes cracks" to the high voltage capacitor, "usually shorts"

I have had the LG model lrm1260sw microwave for 3 years. Recently it quit heating. I found the problem was the soldered grounding lug connection on the power transformer had lost circuit continuity and failed. One of the secondary coils on the power transformer, red wire / bare copper wire, is connected to ground / chassis. I cleaned the lug connection and added a length of wire twisted together with the bare copper coil wire and soldered to the grounding lug. I then grounded the extra added length of wire to another chassis ground point. Make sure the transformer to chassis mounting screws are tight also. Now the microwave oven works like new again.

"Locke" meaning the door? or locked meaning the buttons don't work? If it is the buttons then you have the child lock on. Push and hold the "Start" button for 4 to 5 seconds, and it will unlock.
