My Comcast and Vizio remote no longer respond to the tv. I suspect it's the IR Sensor. I have found the part online but see no information on taking the tv apart. Does anyone have a manual or video on how to replace the IR Sensor of this particular tv, or one like it?

Re: Vizio SV421XVT IR Sensor Help
Remove the back of the tv and the board should be at the bottom. I believe yours would be in the center, some are on the left or right side. There will be a small connector. This board is small, probably a 1.5 inch by .5 inch
If you get the back of the tv off and are still unsure, pop a few pics and we can assist you better if needed -

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?...

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

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 GcnewbieForgive me this is my first request for help on this forum, so if i've screwed up or not followed the rules i should have i apologise profusely.
I have a Dell Latitude 5570 that was randomly shutting down, on further investigation i found that the machine had been shutting down due to thermal events as noted by windows event viewer.
My investigations lead me to the dell diagnostics screen, where i found that there were two sensors out of range which had been causing the shutdowns, one of which was the GPU thermal sensor and the other the ambient sensor.
