    The displayed troubles of LCD1602

    Good afternoon~all,Could anybody here help me out? Thanks for reading my thread firstly.I have some troubles of LCD1602, please give me some time to state it clearly.

    The 1602 is beginning to show normally after writing the programs to board. However,just for a while ,it canít display anymore while the 1602 is also keeping light. If I donít weld the crystal oscillator,the LCD1602 can show as normal,and the MCU I used is MSP430. Whatís occurred? How to solve it?

    Thank you in advance!
    Have a nice day~

    I'm not sure what you want us to say, about an unknown circuit put together with unspecified (but possibly dubious) soldering skills, all controlled by an unknown program.

    You appear to be suggesting that if you don't do something, then it all works.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
