IPhone 5S black screen but ammeter has response

Trouble Phenomenon
Ammeter has response when pressing power button but the screen displays nothing. Replace a new display screen and it shows the Apple logo. Later, blue screen shows up and iPhone reboots.
Repair Process
First remove the motherboard and wire without connecting the power button Flex Cable (VC494). IPhone can be turned normally. Replace a new power button FPC Cable and the problem still the same. Adjust the mute switch to set a mute state and iPhone will reboot after showing the white Apple logo and blue screen. It will be turned on normally under non-mute state. This problem is strange and has not been met before. According the repairing principle of software first and hardware later, enter DFU mode to root. After root, iPhone can be turned on. Trouble is removed.

Check Display with another monitor if not working then problem with display card, if working then Display screen damaged or have a problem. So check it properly.

I have installed a new LCD screen on my acquasmart WL80T65CW1 and teh csreen now shows fault code 9. Please advise how to get rid of it and resize machine. Thanks.


If ever you replace the display PCB or the main controller PCB then you must set the size of the machine in to the memory of the controller. This should of been in the instruction sheet that came with the display.
This Is Fault Code 9 ,which indicates Size setting or
size error . When you changed the display did you size your machine to the new display module? Did you get the re-size set of instructions with the new display board? Ring up where you brought the display from and i"m sure they can help.
If this appears in your screen it will be necessary to set the size of the Aqua smart....

1. Press and hold the SPIN button, then press the POWER button until three beeps are heard.
2. Press the FABRIC SOFTENER button once to size the machine.
3. Press the POWER button.

If nothing works you need to reset your machine, please check the bellow link to get the manual and check page 18 and 23 for the reset instructions.


Please get back to us if you have further query else please accept the suggestion.

Connecting laptop to Monitor

Go into Control Panel> and choose the display settings (depends on your operating system). In the display area look for a screen that allows you to change display settings. Once there, choose the "detect" button which will then allow you to use the multiple display option. Choose Duplicate to show same thing on both screens or Extend to have two independent screens.
