I believe the blue, green and gold are wires wrapped around insulated wires. The blue, green and gold are all ground. You can take these off by untwisting them. The inner wires should be red, black and white. These go to common ground, audio left and audio right. Best would be to check the old jack to see the wiring. This is assuming it is stereo. So the jack has 3 layers. If it has also a mic the it will be 4 layers. Google 3.5mm jack wiring diagram to find more information on this. Best to do this specific for your headset.

If the device is overheating the fans will run at full speed. Dust can be a factor in this. If it is at startup with a cool device it can mean the heatsink and thermalpaste aren’t doing there job. In this case it took a hit and although you don’t see any damage i think some components on the logic board might be damaged. This is plausible because this is located directly under the keyboard. I would take it apart and see if you can spot any damaged components or broken solder.

This question is asked on multiple different forums but none seem to have a definitive answer. Doing some research by watching teardown video’s and photo’s will give you a good indication and then you just have to go for it. And if it’s an easy task to replace the keyboard you can order a new one somewhere with the option to return it. You take of the keyboard and compare it with the new one. If the’re identical you can replace it. Just make sure to document it and share it for the benefit of others :).

Hi Robin, sorry to hear replacing didn’t solve it for you. But don’t give up yet, there are more options. Sometimes it takes a while to find the thing that isn’t working right. I read that a software reset might help. That’s an easy one to try. If that doesn’t work check out iPhone 7 home button not working after screen replacement @rany. Rany put together a extensive list of known facts and number 6 seems like a possibility for your problem. "FACT 6: in some instances, a chip (other than the one in FACT 1) present on the home button is damaged (specially during transfer of home button from broken to new screen). When damaged and failing, this chip will prevent home button function from working such as to exit an app and go back to home screen. But the finger print scanner would still be working and you are able to wake/unlock the screen with your finger/fingerprint and use reachability. This chip is accessible (contrary to the fingerprint scanner chip in FACT 1 which is practically unreachable) can be...

I advice you to Why won't my television power on. It is not the same model as yours but most of them seem to work the same. To recap some of the key points form that post and general advice: (1) unplug everything including the power cord. Wait a minute and plug the power cord in and try if the tv works. (2) If it doesn’t work see if you have warranty from Hisense or the store you bought it from. Even if you do not have warranty you can contact Hisense customer service and ask if they have a solution. (3) If that doens’t work you’ll have to find a solution yourself. It seems most likely to be a power source problem or backlight. This means taking your tv apart and finding out if you can repair it. Of course you can always come back here with additional questions on repair if that’s what you end up doing yourself.

You can disassemble the earpieces. These consist of screws and plastic tabs. You already did (most of) that. I don’t know a way to open the headband in case you need to replace that cable. You can try to push or pull new wires through.

Cleaning and reassembling seems like your only option? Personally i would not dip it in any liquid even IPA. Use compressed air to get rid of the most dust and dirt. Then wipe it with a clean soft cloth and IPA.

When bluetooth pairing most devices have blue or white leds flashing. Red is most used as a problem indicator. I suggest you try a reset of the headphones following the Beats by Dre instructions. Reset Make sure your headphones are not plugged in to your USB charging cable. (1) Press and hold the power button for 10 seconds. (2) Release the button. (3) The battery Fuel Gauge LEDs will all blink white, then the first will blink red—this sequence will happen three times. (4) When the lights stop flashing, the reset is complete. Source After that try to pair again: Pair your headphones To pair your headphones with your device, follow these steps: (1) If you were using the RemoteTalk cable, unplug it. (2) Turn on your headphones. Hold the "b" button  down for 2 seconds to put your headphones into pairing mode. The LED indicator light will pulse white. (3) To connect your headphones to your device, select Solo2 Wireless on your device. If you’ve used Beats Updater to rename your headphones, that name will...

Did you charge it before turning it on today? Sounds like a low battery indication.

I’m not completely sure about this but i think (1) Red = positive (power) (2) Black = ground (3) White = data? To be sure look at the type of connector you have and search for that + ‘ wiring diagram’ .
