I have a Sharp 50LB371U smart tv that I'm rebuilding. Everything works except when leaving it off for a while, the Ir sensor does not respond to turn it on. It will come on if I use the manual power button and the remote works as it should. All buttons work and I can use the remote to turn it off. The remote will work if I immediately turn it back on and off, but after 30 min or so. UGH! remote does not turn it on again. Have used 2 new remotes and purchased another main board and power supply. Same results. Any ideas?

Re: IR sensor is baffling me
Could be the little capacitor/s on your ir board, with 2 board replacements not sure what else it could be, did you try a firmware update? -
Re: IR sensor is baffling me
There are so few components on the IR board that it would be worth touching up all the solder joints.Willing to help but I'm no expert.Comment

by CapLeakerGot 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?...

by JackchingDoes anyone know if there is a repair for the remote sensors for these televisions? It only seems to work when it wants to. I tried a different remote and also tried factory resetting the TV. I find if i go close to the sensor that it'll work but outside 2 feet it wont.

by pajdekHello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

by groomitHi,
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... -
by RdeveLabsTo all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... - Loading...
