Hi guys,
I have a dead coffee machine, and it seems that the culprit (no 1, at least) is a dead trafo - primary coil seems to be blown open (type shown on the picture below).
Now, I'm unable to find direct replacement anywhere on ebay or aliexpress, and all similar that I' was able to find are rated too low (<1A).
If someone knows a shop to buy replacement (EU/CH), that would of course be my 1st option.
My other ideas:
- to buy 220/20Vac trafo with 30VA, and to "manually" create secondary 12V output just via resistor
- to buy... -

Here is a pretty crazy one.
Step 1.
Laptop was brought to me as dead not working. Removed everything , cleared everything.
Step 2.
Some liquid damage close to the Type - C connector, and the connector even though it was cleaned wasn't charging the battery . Removed the Type-C port, and replaced it. Now the laptop turns on and charges battery. Shows external screen , not internal.
Step 3.
Took out the screen and checked it to a secondary Gen 2 i have, screen works like a charm.
Step 4.
Lets ,dive into the board. I see the edp cable on the... -
OK, this is a long shot. I got this sewing machine cheap because it's end of line, ex-display, and had no pedal. The genuine pedal costs £60, while Ebay knock-offs go for around £15. So I went for the knock-off, it doesn't work, and I'm not sure whether it's the pedal or the sewing machine that has the problem.
Now this is an electronic machine, unlike the old fashioned sort where the pedal was a big resistor in series with the power to the motor. Here, the pedal is just (I think) a variable resistor fed with a 5 volt supply, and limited to a current of 5 milliamps. Assuming that... -
Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.
