Samsung Television: Ribbon cable causing issue

Tue, 28 Apr 2026 14:19:35 -0700

Hi, so my Samsung tv’s auto timer turned the tv off and the tv would not come back on at all. I have taken off the back of the tv and checked the power, main and t-con boards and all appear to be ok however tv is stuck in a boot loop unless I remove the ribbon cable from the main board to t-con board then the boot loop doesn’t commence the tv turns on as normal. Now for the confusing part…when I disconnect the ribbon cable, let the tv start up and finally reconnect the ribbon cable the tv works perfectly however once turned off the boot loop starts again until the steps are repeated. I have seen “fixes” on YouTube etc for a similar issue which uses electrical tape to cover 1 or 2 receivers on the t-con board this usually isolates a spot of led’s and leaves a visual defect on the screen. This doesn’t seem Like the correct fix for my TV’s issue as the entire screen works flawlessly when I have removed the ribbon cable and inserted it again. Is there any known fix for this or a way to stop the t-con sending the signal to turn the tv off? Thanks.

Turtle Beach - Stealth Pro: My microphone stopped working

Tue, 28 Apr 2026 10:21:31 -0700

The issue is the microphone stops working. Prior to it stopping, it would work at half-mast. It is a design flaw. Apparently, the wires that connect to the microphone come loose. It is caused by moving the microphone boom up and down. I can't find anything on how to break it down to access the wiring. Any help is greatly appreciated.

iPod Touch 5th Generation: Can I swap an iPod touch 6's casing on a touch 5?

Tue, 28 Apr 2026 05:07:09 -0700

After cutting my hand open trying to take the "iPod loop" off my old casing(my replacement that I bought in China didn't come with one somehow) I now decided I hate that thing and was just wondering whether I can just slap an iPod touch 6's casing on a touch 5 and call it a day. I saw the teardown and repair videos of both devices and it seems to me the only significant difference is the prescence of the pointless "iPod loop" on the touch 5.

Can anyone confirm whether I can swap the casing between them? thanks in advance

The only thing to remedy the god awful sound is to turn off the active noise cancelling via the Headphones app. Is there a manual on how to fix this?

Xiaomi Bluetooth Speaker: Bluetooth Speaker not charging.

Mon, 27 Apr 2026 10:02:27 -0700

Hi,

my Bluetooth speaker stopped charging one day. As far as I know it did not suffer any physical damage or anything of sorts. I used to carry it with me sometimes but usually in a bag.

It still has some juice in it because it turns on but after a few seconds turns itself of with not enough battery. LED indicator doesn't even lit up when I connect it to USB cable.

I already opened the device and well everything looks in place. So, if anyone have any idea of what might be the faulty part I would be grateful for suggestions.

It's actually pretty cheap but I am kinda curious what went wrong.

Thank you.

Mon, 27 Apr 2026 07:21:39 -0700

After using it for 20 years and putting weird Rockbox - related stuff on it my iPod nano 2's drive is now completely broken. It became a RAW drive a while ago and now my computer can't even format it. I'd like to swap a new storage chip onto the Nano 2 but I have no idea what kind I should buy and the max storage it would support. Can anyone confirm what kind of chip I should buy and the largest amount of storage it would support? thanks in advance🤓
