CMF Headphone Pro: Headphone fell and left ear sound is shaky-on/off, how do I fix?

Thu, 27 Aug 2026 07:53:20 -0700

Headphone fell from a waist level height say about 3ft. Left ear is shaking, rather sound doesn't come through unless I tap or twist a tiny little bit on the headband.

Panasonic Viera: Panasonic viera txp46gt30b Help please, 7 blinking light on startup.

Thu, 27 Aug 2026 07:53:56 -0700

Hi, I’m having the 7 blinking lights issue with my Panasonic Viera txp46gt30b.

I switch it on, red light blinks 7 times and then it switches off.

I have tried the general trouble shooting as well as following some online guides to try and find out what specifically isn’t working so I can fix or replace it but as of yet no luck.

I’m assuming it’s probably an issue with sc board but no idea how to accurately pinpoint it.

Any help would be appreciated.

Pics of the TVs guts added in case it helps.

Meta Quest 3: Update and restart loop

Thu, 27 Aug 2026 01:44:40 -0700

I have bought this device used, so I have no warranty.

The device keeps updating and restarting, side load update didn't work because the site said incompatible device or something like that, and factory reset didn't work either (it reseted and still had the loop).

Is there some different manual way to fix that, maybe somehow completely wiping the quest 3's SSD and manually installing the OS?

Beats Studio First Generation: Can I fix the cracked headband on my beats studios?

Wed, 26 Aug 2026 19:17:13 -0700

The top plastic part of the headband on my headphones cracked. I tried to fix it with superglue, but that did not fix the problem and the headband now looks tacky. Is it possible to buy and install a replacement headband? If so, how do I install it?

They are a pair of black first generation Beats Studios.

Thanks! (:

This isn't the best pic of the crack, but here is what it looks like:

Boat Rockerz 450: The slider broke, superglue is not fixing it.

Wed, 26 Aug 2026 19:09:22 -0700

I have been trying to stick this with superglue but it keeps falling apart, even after waiting 10-20 minutes for it to cure. Can someone suggest alternative methods to stick this? The headphones work fine its just the slider thats broken.

TCL Television: TCL 55C803 Roku TV. Blank screen, but blacklight is on.

Wed, 26 Aug 2026 18:36:04 -0700

I have a 55 inch TCL 55Ç803 Roku TV that I found at someone's curbside for trash. The remote and power cord was included. The unit is very clean and no physical damage, so I optimistically brought out home for testing.

The TV powers on, lights up (but no image) and is dark with no lines etc. I can turn volume up and hear the familiar clicking of a the roku device imbedded, but no screen to navigate. Again can see the glow of the screen so assuming the LEDs are lit, but no menu images.

I've tried the well documented reset with the remote ” press home page button 5 times, 1 up arrow, 2rewind , 2 fast forward" and it then go through the reset process and turns TV off and on twice and ends up the same with the bottom tv indicator light flashing like several fast and a couple slow or something.

Again the screen is lighting up gray and can see it's lit up from inside. Seems a little darker on half the upper screen, but still lit up Any ideas?

I'm computer technical savvy, and would be comfortable taking it apart, but don't want to waste precious money trying to guess at replacing parts as I have no history on the TV and I realize it might exceed it's value to repair.

But I would sure love to fix it and use as I could not afford to buy such a nice TV.

Hoping this turns out to be a Thanksgiving blessing and gift for our family. Thanks in advance for any help.

Samsung HT-J7500W: Sound coming from left port has a hiss.

Wed, 26 Aug 2026 01:26:55 -0700

Hello! I have a Samsung HT-J7500W surround system that makes a hissing sound on all sounds coming from the left port. I've tried buying a new cable and switching the speakers to make sure none of these were the problem and the hissing stayed in the same location.

Sometimes unplugging the system for some time makes it stop making that sound for a while before it starts going again. I've also noticed that louder sounds and volumes seem to "trigger" the hissing quicker. I don't know how to go about troubleshooting this and would appreciate any guidance. Will provide any requested photos. Thank you!

Samsung Galaxy Buds2: The Case Hinge has Failed

My Galaxy Buds2 case hinge has failed. It won't open all the way and won't shut properly making charging difficult. I have to put something on top to keep them shut despite the magnet closure. Is it worth it to try to repair the hinge? Should I try to replace the case, or should I just go ahead and get the newest model?

AirPods 3: AirPod has two different volumes

Wed, 26 Aug 2026 01:02:43 -0700

This is gonna sound nuts. I have a pair of AirPods that have been very quite, like I need almost full volume to hear them. Now I lost one AirPod, did my wash, and you can guess where I found it. In the washer. Now this washed AirPod was sitting in the sun (as recommended on this platform) ,and now the %#*@ audio works amazingly. But of course this is only for the one AirPod and the other is still quiet. I don't know what to do or how to make them even. Any help?

Meta Quest 2: Why does my left controller stick have drift?

Tue, 25 Aug 2026 23:51:07 -0700

I was playing the walking dead: saints and sinners for the first time and I noticed I was slowly strafing to the right. I took it as the game's push mechanic and just kept playing. I then hopped onto vrchat, and truly noticed the stick drift. I haven't seen any repair guides for the quest’s controllers, so I'm wondering if anyone knows a fix?

Roku 3: roku keeps shutting off

Tue, 25 Aug 2026 09:04:36 -0700

why does my roku 3 keep shutting down?

Thanks but I did. Tried different HDMI as well as the three RCA jacks and also 2 different tv’s. I also reset the Roku to factory settings and even then, it shut down while loading all the channels. As I was re-setting it up it accepted the wireless name/password and started to load 1 of 88 channels but shut down while the channels were loading. I unplugged and plugged back in and it started loading 1 of 52 channels then shut down again midstream. Re-booted again and loading 1 of 33… shut down a couple more times but finally completed. After ALL that back to the same thing. after 2 to 5 minutes of watching whatever it shuts down.
