Hi Johan,
I ordered this MOSFET (https://www.ebay.com/itm/171027560618). They are sold in packs of 10, so I have 9 spare ones. If you want to I could send a couple to you (for free). I too have some basic soldering skills, but it is a very small solder, so I got help from a friend of mine who...
Hi again,
It took me some time to get a hold of the right MOSFET as well as to find someone who could change it for me (Denmark is pretty much in lock-down). Yesterday it was replaced and now IT IS WORKING PERFECTLY! :D
Thank you so much for sharing your knowledge. It wouldn't be working...
That is indeed what I did... Just to be sure I will measure it again when my girlfriend is back home (need an extra hand to touch the sensor while measuring). If those measurements are in agreement with the previous (+1.2V) I will go ahead and order a new MOSFET. When it is replaced I will get...
Dear Dougy,
Thank you very much for taking the time to help me and for informative answers, you´re fantastic! If you want to, you can pick a charity of your choice and I will pay your help forward with a donation to that charity.
I have got a hold on my multimeter and have done some...
Dear Dougy,
Thanks for the reply. I have attached more detailed pictures of the circuit board, does that help you to help me? :)
I prefer to change the circuit board or necessary parts on it to keep the lamp in it original design.
Best regards,
Tobias
Thank you for the reply. Not sure if transformer is the correct word (I'm not a native to English), but isn't the larger circuit the one that converts the voltage from 220V AC (main supply) to what the LED uses (DC and probably 12-15V or so)?
The separate circuit board, which the touch sensor...
Dear Electro-tech-online,
I am repairing a LED floor lamp in which the touch sensor (for on/off and dimmer) has broken. The lamp itself is an 8W LED. It is wired from 220V to a transformer (located at the base of the lamp) to the broken touch sensor circuit board (located at the top, beneath...
