    Sony WH 1000XM4 Headphones always on because of corosion?

    Hi all,

    i got these headphones which were not charging or powering on. I found some corosion around the charging port and power board. After cleaning the headphones took a charge but directly powered on.
    The power button ist without any reaction. I suggest that there ist still some gunk under the button and i get an always power on. Do you have any suggestions what to do? Is it possible to desolder the button for a cleaning?
    I could replace the board for 25 euros but maybe there is another way?

      Connecting charger cable causes Sony WH-10000MX2 bluetooth headphones to stop working
      by Califauna
      Hi,

      I have a pair of WH-10000MX2 bluetooth headphones with a strange problem. Connecting the charging cable causes the headphones to no longer turn on when pressing the power button.

      I thought I had 'fixed' this when I took them apart and disconnected the battery for 15 minutes and found as soon as you disconnect the battery they can be powered on and off as normal using the power button. But then the moment you connect a charging or data cable to a charger or laptop USB port, the power button stops working and the can't be turned on again. No response.

      WH1000XM4, Sony headphones exploded view & parts list please
      by zen
      These headphones sell for between £250 - £300 so well worth going into.

      Need to identify earpiece swivel brackets LEFT/RIGHT.

      Right side damaged.

      Manage to modify original & now works quite well, but it does seem to be a weak point on these headsets therefore would like to have some in stock for future repairs.

      Firstly, would like to find out if Sony supply these as separate parts & if not then try to have them 3D printed.

      Can anyone help?

      RCA WHP141 wireless headphones wired up
      by momaka
      OK, this one dates back to 2015! I thought I had posted this, but realized I didn’t when I posted a picture of something else. So here it goes…

      Back in 2015, I bought a pair of RCA WHP141 wireless headphones at Micro Center for $2. I even mentioned it in the best cheap/free scores thread right here. Just forgot to follow up with that.

      As mentioned back then, these are (were) 900 MHz FM wireless headphones. No modern day Blutooth or anything like that. I knew they wouldn’t be great headphones or even that good… but the price was right! So let’s take...

      Sony KDL-46HX850 Can't upgrade/update firmware
      by dkneyle
      Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.

      Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about...
