AirPods Max: Digital Crown Flex removal

Thu, 16 Apr 2026 07:45:29 -0700

Hi there,

I am working on replacing all the ANC mics on my APM due to hiss. I got the left fixed, but hit a snag with the right. This mic flex also includes the button for the crown, and I cannot see how on earth I get that off the old one. You can see in my picture that the screw has zero room to get to it, same on the bottom. Does anyone know how that is meant to come off, or how I detach the crown to get to it? Is there a special tool I need? Thanks!

JLC JLC47BC3002 Television (47"): JVC SI50UR: Sound but No Picture - Vertical Lines & Tape Fix Attempt

Thu, 16 Apr 2026 04:53:04 -0700

My JVC TV (Model SI50UR) has sound but no picture; it only displays vertical lines. I already tried the DIY trick of placing tape on the flex cable pins, but that only changed the pattern of the lines. Also, when masking certain areas, the lines react to the remote control inputs.

iPod Touch 7th Generation: Can't remove the front display!

Wed, 15 Apr 2026 11:16:52 -0700

It seems impossible to remove the front display! I used the iOpener repeatedly, a heat gun, all to no avail. I bought a new display and all the tools to replace it, but I can't get started. The adhesive just doesn't want to budge! Help!

Jabra Evolve 75 Headset: Does anyone know how to repair the mic?

Wed, 15 Apr 2026 02:37:57 -0700

Hi everyone

I have two Jabra Evolve 75 headsets, both with the same problem: The mic is not working anymore.

I suspect that after being raised and dropped X-many times a wire got loose inside but I can't find anyone brave enough who would open the headset and check if that is actually true.

I am super happy with this headsets and I really don't want to spend 300€ for new ones. Everything else is working perfectly, except the mic.

I hope there is someone who can help me out.

Hey Team,

My MI 4A TV is neither starting from the remote nor from the power button of the TV. The red light always keeps on burning in the TV, which used to turn off after starting the TV, but now it does not turn off.

Casio FX-991EX: Calculator is in 'PAUSE' mode

Tue, 14 Apr 2026 23:17:51 -0700

The calculation was done in VECTOR mode from the menu. When trying to do something, the calculator hangs, after clearing by the 'ON' button, you can see this status of MENU. Apart from these 3 modes, no other mode is showing, if I want to scroll up or down, the pause sign (2nd picture) is coming on the upper right side.

⁉️ How to get back all mods like before?

Panasonic plasma 50 inch tv: Red led blinking 8 times

Mon, 13 Apr 2026 20:25:38 -0700

Panasonic Plasma P50ST60A

My Panasonic plasma won’t turn on.

The red LED blinks 8 times after I try the power button.

Is this something I can resolve myself?

My local repair man says it not worth repairing.

The panel has had little use so I would like to try and save it.
