How long does the system stay on and does the light go white at any point? Do you get anything on screen like a flicker or static? Has the system ever taken a hard hit like dropping or something being dropped on it?

I am guessing this is an Iphone 6 or 6s. That is the wifi antenna. To replace that antenna you have to take every part out of the phone to get to it. Here is one on ebay. ``https://www.ebay.com/i/372198220826?ch...-117182-37290-0&mkcid=2&itemid=372198220826&targetid=9...-934793863176&abcId=9300401&merchantid=10...-oCbxik-kp57mVoD9wnkJZGb3rXxoCUiEQAvD_BwE``

A loud pitch hissing sound is common in capacitors in any device. When a capacitor fails the liquid dialectric will hiss out and the capacitor will swell. A microwave can not run on 120 volts at 20 amps very well so the capacitor charges like a temp battery then discharges into the magnatron to cook the food. Microwaves have capacitors as high as 10000 volts at a low amperage. High amperage would require wires the size of a few fingers to move the power but high voltage does not. The capacitor will hold less and less power till it is not discharging at all and your food will not cook. Unless your microwave is fancy it is not worth fixing and the capacitor is not a DIY item due to the ability for a capacitor that size to throw you across the room with more force than an angry gorilla. Tube TVs used 2000 or so volt capacitors and my grandfather still hit the wall on the other side of the living room from it. I have been interested in electricity ever since.

First off that is not an lcd it is an Amold screen that is oled and that makes the job harder. Amold are used because they are much thiner. The oled is the expensive part so just buy the whole assembly. But I will still answer the question. You would need a digital temp controlled hotplate to heat the gel that glues the screens together then cuting wire to seperate the screens and then a desolving agent to remove the extra gel. Then you must glue your new Amold oled screen to your old front glass and digitizer and then the glue must be set using a uv light so that the glue can be trigered from under glass like how gel nails work. You can skip the glue but the screen will look foggy and dull. A cheap digital hot plate costs about $100. Cuting wire is cheap and so is the glue. The glue must be applied in an x pattern and the screen lowered from one side to spread the glue evenly with no bubbles. Be carefull with the solvent that removes the old gel. If the solvent gets on the underside of the Amold screen it...

Ok white screen explained. Ipods are like little computers with a simple graphics card hooked to a display. If you disconnect this display and put a different display on while the device is not powered off you get a white screen and yes you may have turned the device off but that power button is very easy to bump while doing this repair. So just like any computer each screen has to be calibrated for your computer and so does an ipod screen. Ipods do this calibration durring power on test. So the trick in fixing the white screen is to get the ipod to power off and back on. The button holding instructions for a hard reset will work if you can time them right but as long as no password is set on the device just open itunes with the device connected and tell itunes to backup the device. Then when the backup is finished tell itunes to restore the device from the backup you just made. Itunes does a hard reset after the restore to finalize your setting changes. So if you have a password on a broken screen ipod go...

The pinouts dont matter the back light just needs power if you can hook power to the two silver solder points on top of the lcd connector it will light.
