Is there any way of reapplying it to make the repair OEM?

If someone does so, please let me know.

Thank you and good luck!

Samsung Galaxy Buds: HELP:My earbuds come up as two separate Bluetooth devices- How to fix?

Fri, 28 Aug 2026 12:11:08 -0700

How can I Force the two earbuds to sync up and become one Bluetooth device?

They are coming up as two separate Bluetooth devices in settings and I can only connect to one at a time.

Is there a way to force reset them?

Disclaimer: I cannot Reset through the app as that only works with two of them connected. Right now I'm the wearables app there are two separate devices.

Mi 80 cm (32 inches) Horizon Edition HD Ready Android Smart LED TV 4A L32M6-E: Voltage details back light not working

Fri, 28 Aug 2026 09:54:25 -0700

Voltage details

LG Television: LG OLED55C14LB is on for about 20 seconds before turning off.

Fri, 28 Aug 2026 08:12:27 -0700

I believe i came a long way with my troubleshooting so far. From my voltage measurements the PSU motherboard works as it should, however there's two cables that goes from the PSU into the displaycard, one 12V and one 22V line. If both of these are connected and i start the TV i have 22V and after 2-3 seconds it drops to 19,7V instead and if we wait 20-30 seconds the TV turns off until i press the start button again.

What i found after this is that if i unplug the 12V cable from the display card and try to start the TV i do get a steady 22V and the TV wont shut off at all but obviously no picture. And once more if i keep the 12V connector in place and remove the 22V i do get steady 22V on the PSU side. The question now is, do i have a faulty display driver motherboard or is the panel itself at fault here? i'm lost dont know how to progress further.

Any help would be greatly appreciated :)

Meta Quest 3: Update and restart loop

Fri, 28 Aug 2026 01:28:35 -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?

Panasonic Home Stereo: Can someone help identify the part I need for my power supply

Fri, 28 Aug 2026 01:01:43 -0700

My Panasonic SA AK 240 CD player from 2006 wouldn’t leave standby mode so I disassembled remove the power supply and found a part is burnt. I’m not even sure what to call this thing. It’s not a fuse and I’m pretty sure it’s not a capacitor it has no numbers written directly on it. I was hoping somebody would know what these are so I can try and buy a replacement piece. It says 05950 underneath

LG Television: The audio in my lg tv stopped working for some reason.

Thu, 27 Aug 2026 21:24:27 -0700

Hi,

I have had my LG smart tv for about three years now. The sound for it recently stopped working yesterday feb 20th. I looked online for several solutions to solve the issue but nothing seems to work. Model number. 42LB5600-UZ.AUSDLJM.

Can anyone help me solve this issue if you had it at one point with the same brand?

Thank you

Apple TV 4K 2021: Is it possible to fix directional keys?

Thu, 27 Aug 2026 12:44:11 -0700

My Apple TV remote is working mostly, but the directional keys for down and left are not working anymore. Trackpad still works, as do the other directions.

I’ve already been able to open it up, cleaned with alcohol, but that doesn’t seem to do anything.

Does anyone have tips for other things I could try to get these buttons to work again?

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

Thu, 27 Aug 2026 10:20:50 -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.

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:

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.
