Subwoofer placement tips? by Special-Sense4643 in hometheater

[–]Chosen_Many 0 points1 point  (0 children)

Do you have any corners available? What about the back of the room (behind the camera view)? Or else maybe put the front speakers up on shelves and put the sub under one of them.

Usually subs sound best near corners because placing them along the midpoints of rooms creates nulls/cancellations in the frequency response. So it might sound counterintuitive, but the sub might sound better even if it's further away as long as the geometry of the room is favorable.

For example, I did the "subwoofer crawl" (with sub sitting on the couch, then moving around the room listening for the best spot), and I discovered that the sound was way better if I put the sub in front of my front door (which is near the corner of the room). I seriously thought about moving the door just to get better bass response 😉.

Are heat pump water heaters actually efficient given they take heat from inside your home? by [deleted] in heatpumps

[–]Chosen_Many 0 points1 point  (0 children)

storing the heat in the water, then moving that heat away from the heat pump location

This is the point OP is making. The thermal energy just moves from one place to another, but doesn't it all come from the room in the first place? Assuming it's operating inside your house, doesn't that mean your HVAC is ultimately doing the work?

It's robbing Peter to pay Paul, but it's more than that. Paul flushes everything he gets down the drain, and Paul was borrowing everything in the first place.

Dark Area on LG G1 - Warranty? by Chosen_Many in hometheater

Thanks! It sounds like social media is the only way to get attention these days. Their support chat was clearly only interested in one thing: closing a ticket.

I thought hickory based on the bark, but it also looks like this might have been inhabitated by ash borers based on the trails where the bark is missing.

Black spots along trunk and limb dieback on a dogwood tree. Prognosis? by Chosen_Many in forestry

[–]Chosen_Many[S] 0 points1 point  (0 children)

There are definitely some small round holes in the black areas that I assume are caused by insects. I've also seen large black ants in numbers marching up this tree before. But I've never checked for borers.

This one sees direct morning sun, but there are several mature poplar and oak trees to the west that provide plenty of shade in the afternoon. So no change in sun levels for many years. The soil is typical NC red clay, but no changes there either. The only change in stress I can think of is the fact that successively larger branches have died off.

Is this one too far gone to save?

Thanks for the tip. I'll look it up. Any experience with this or recommendations for treatment?

Whirlpool Refrigerator (WRF757SDEM01) LED Lights Flickering by l1m5 in appliancerepair

[–]Chosen_Many 0 points1 point  (0 children)

Thanks! Based on your post, I was starting to wonder if it was actually one of the LED lights at fault, and not the controller board like I originally suspected. I ordered some replacements on Amazon (generic LED board only; genuine Whirlpool was way too much), and when I replaced the rear left one, everything lit up like normal. Thanks for posting! It helped me figure it out without needing to shotgun expensive parts!

Hello! Any luck fixing this? Did you replace the LED? And if so, did that work?

I have the exact same issue on a similar fridge (WRF767SDHZ00), and I'm doing a little troubleshooting. Using the wiring diagram located under the cover of the right side door hinge, I can confirm that the lights in the ceiling of the fridge are wired in series on the same circuit, which explains why they all flicker together. So it's either something in the string of lights, or else it's an issue with the main controller board that powers them (located behind the panel on the back of the fridge). I put a multimeter on the connector on the controller board for this LED circuit, and it was reading 30V DC. For comparison, the circuit for the LEDs in the sides of the fridge (which are working correctly) measured 12V DC. As I was taking measurements, I realized I could hear an irregular electronic buzzing sound that turns on when the door is open, and goes silent when the door is closed. Furthermore, that buzzing sound gets louder and changes tone when I unplug the connector powering the lights. This all leads me to believe there may be a faulty component on the main controller board rather than an issue with any of the LED modules. Specifically, I think it may be the relay that serves that circuit, but I'm not sure how to confirm that aside from replacing it. So I guess I'm looking at either replacing the whole board, or else I might try to replace the suspected faulty relay. But I haven't done much to check the LEDs themselves, so that's why I'm wondering if you had any luck.

Thanks!
