![]() I heard somebody suggested a way of repair faulty led light bulb which I have never heard of. The way is to put the led light bulb inside a microwave oven and turn on the microwave oven for a few seconds. He said that faulty led light bulb is usually caused by poor solder joint between the led and the pcb. Putting the bulb inside the microwave oven for a few seconds will heat and reflow the solder joint making it works again.
Is that possible? I do not want to try this unless I have a spare microwave oven. (I do not mean to suggest somebody to try this. It may be very dangerous. If you want to try, you are taking your own risk.) |

![]() In a word NO. The microwave energy will NOT heat the solder and any coils/ circles of wire will likely be destroyed.

![]() The LEDs of the lamps are usually 30mA and inside they have 1, 2 or 3 LEDs, generating drops from 2.7v to almost 11v, I test them with a current limited laboratory source. Normally the LEDs burn out in those cases you can directly bypass and go

Now, a CONVENTIONAL oven could potentially reflow solder at the right temp. I had a 2007 Mac Pro video card stop working, and I stuck it in the gas oven at like 400 or 450 I think (might have been higher I can't remember) for 10 minutes (might have been longer), then took it out and let it cool and it worked fine after that. I can only assume there were some micro-fractures in a solder joint somewhere. The computer was about 9 years old when I did that. Mike
