    Hello, thank you for the vocabulary terms. I didn’t read anything about faults being that the screen will stay blank(black) but the phone is still on and notifications light is still on. Would you be able to tell me what part or name that would be causing that? Thank you in advance!

    • Yesenia says:

      I got the screen to turn on, but now there are vertical colorful lines all over the screen especially if the background is black.

    I have a LG G3 which went ‘Blue Screen’ one fine day. Since it is out of warranty, I got it repaired at a local service center. The repairer said that he has replaced one of the ICs and resoldered. After resetting, the phone was on Android 4.2.2 and is not getting updated to latest OS like Marshmallow or Lollipop. What might have gone wrong?

    I put the inside of a contract phone with a shattered screen inside a prepaid phone both are the same type of phone. I thought by doing this the prepaid phone would now be the contract phone and I would be able to activate it however it is still asking for payment when trying to make a call what part of the phone did I not switch out to cause this?

      Disassemble the Phone and Clean the PCB and all other Parts with IPA or Alcohol or Petrol and Leave it to Dry. Assemble Back and your mobile phone will be OK. You can watch my video on how to Disassemble and Assemble Back a Mobile Phone.

    Good day sir, I have been going through your writings/articles and is very helpful most especially to those engaged in mobile phone repair specialist.I do specialises in iphone and ipads repair and find it very difficult to deal with the glue that comes on iphone pcb at times you might damage the board from powering in the process of removing or Desoldering some ic’s on the pcb and secondly I was wondering if you can explain parts and their function in iphone most especially iphone 6, quide and equipment or machine to use in iphone/ipad pcb repair thank you and more grease to your elbow

    • Santosh Das says:

      Hello Mr. Ahmed: I like and respect your question. You questions are excellent. Yes, the glue is called SMT Glue and is very-very has very strong bonding. There are machines available to remove these glue but the machines are very expensive. I will certainly write an article on this glue issue and parts inside iPhone and their function.
