I tried searching but didn't see any problems with IR sensors listed. I was wondering if anyone has fixed one. I found a website selling them with cores. I assume they are repairable. If not I may just purchase another.

Got a new victim:
AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
A: outside temp stuck at -40?
It's cold here at times in Canada, but not that cold!
B: stuck at some temperature and maybe updating once in 12 hrs or so.
Easy solution is to go to AcuRite website and purchase the sensor. Right?...

I will just preface all this by saying that I have a fairly technical background but have never attempted SMD electronics diagnostics and repair before, I really like the idea and want to learn.
I have a MacBook Pro late 2016 that died maybe four years ago. Over the course of 30 seconds, it got slower and stuttered, until it froze for a second and died. No click from the trackpad anymore, nothing. I started getting interested in electronics repair and decided to give it a shot, so I opened it, removed the battery (one cell was puffy), took out the motherboard and experimented with...10-15-2025, 01:53 AM -
I've got a dehumidifier that has stopped working. Plug it in, press the power switch, and it beeps 5 times. Nothing showing in the display (which is just two 7 segment displays) apart from the two decimal points flashing. The model is a MeacoDry Arete One 18L, which seems to be a rebadged Deye (all the boards are marked Deye). Here's what I've got so far (details in case anyone else in future should need them).
Starting with the power board. Mains power comes in at the red connector top left. The compressor is powered by the orange connector to the right of that and is switched by... -
Hi,
I just replaced the battery on a Google Pixel 5.
After that the proximity sensor isn't functioning properly any more. It is constantly activated. So when playing a voice message on Whatsapp, the Screen instantly turns off.
Checking with a sensor app I can verify weird behavior of the sensor. It is triggered when nothing is near and sometimes works correctly when squeezing the phone next to the sensor hole.
The rubber seal is on again (as mentioned in various suggestions in other forums).
This smells like a cold or broken solder joint. So I'd like to reflow... -
Hello, I will have to solder a very small FPC connector (pins : 0.3mm), on the pcb of CMOS sensor, it is very close. I was surprised by movie on ytb, someone soldering directly with hot air directly on the sensor without kapton, nothing.
CMOS sensor seems resist to high temps.
But I also directly saw sensor broken because a blocked motor at the corner became very hot and probably bent the metal frame and cracked the sensor.
I have low melting point solder.
I will probably test hot air directly on one of plastic connector (I have a lot) at 320 degree on a test...
