Good chance it could be a bad T-con board. Just for kicks, have you tried going into the Picture Settings and turning off the C.A.T.S feature? If you go to Settings > Picture Mode (then create a Custom picture mode) > (scroll up to) C.A.T.S = Turn it off. Probably won’t do anything, but this is the setting that controls screen brightness fluctuation. There’s a video on YouTube of a guy fixing this problem by whacking one side of his TV with a rolling pin and the picture pops back on again, probably something loose, but I wouldn’t recommend that (haha) https://www.youtube.com/watch?app=deskto...

When you say it ‘goes up’ do you mean it starts out lower and the volume rises and rises until it’s loud, or is it one second quiet, the all of a sudden really loud? Does the volume go up and down as things are changing on the screen? Like between each commercial? Just wondering if you have some kind of ‘TruVolume’ or ‘Night Mode’ - type of feature that is causing your leveling to change.

This is a common PS4 defect. You can try giving it a little whack/tap with the palm of your hand or a rubber mallet a few times (not too hard), turning it on its side a few times, unplugging the unit and plugging it back in again. Basically giving it a little jostle. If none of these fix it then you may have to return it. These have worked for some but not all with this same exact problem.

I can throw out a suggestion to try for the battery itself: If your phone battery is old and you want to check if it is‘physically’ no longer able to hold a charge, pop it out of your phone and hold it in between your fingertips. Run your fingertips along the flat sides of the battery and feel if there’s any slight lump or bulge in its casing. If there is, there’s good chance your battery is toast.

They make these little stickers that you can put on… https://www.ebay.com/i/183186126971?chn=...

Hi, could be your proximity sensor on your phone. They go black so you don’t hang up on people with your cheek during a call, but it should come back immediately after you take it away from your face. Depending on your phone model, it may allow you to adjusted this in settings. However, a few things to check: (1) Have you recently started using a new case? It could be triggering the proximity sensor. (2) Is the sensor area dirty? (3) Have you tried a reset lately? Sometimes the classic ‘turn it off/on again’ works magic.

Can you take the memory card out of the phone? If so, take it out and put it in your laptop’s card slot, you may need a memory card adaptor if it is a ‘micro’ SD card to bump it up to the right size for your computer’s card slot. There’s a chance your photos are on there.

Do you feel like the Fonz when it goes back on again? :) If it's full of water and not spinning then it's most likely your lid switch is broke/or breaking. When you're hitting it you're probably knocking it temporarily on and then the machine shakes and it goes off. Try this: https://www.youtube.com/watch?v=pghabRPu...

If it stops spinning AND it's still full of water, it could be the lid switch is broken. It may have cracked or something when the rug was rocking and rolling in your washer. Found this on youtube:

Is it wireless or wired? If wireless could be the batteries, or a Bluetooth issue. If it is wired, and you have another computer or laptop you can use, you can try the keyboard in one of those and see if it is still not working. Then at least you'll know whether it is the keyboard or the computer.
