Gunitronics Posted September 7, 2019 Report Share Posted September 7, 2019 Hi, I have a mostly functional v570 that I would like to refurbish to build a demo machine. Unfortunately, the LCD ccfl backlight inverter is shot and the screen does not turn on but the rest of the PLC is fully functional - which I confirmed by connecting over COM1, updating the OS, downloading a new project, monitoring/controlling registers/IOs, reading touch coordinates/toggling the onboard buzzer, etc). I am very interested in ideas how any of you were able to resurrect dead LCDs. (This is not a question about the boot / blank screen issue, I know how to recover from that. This is a hardware issue with a bad ccfl backlight inverter (or bad LCD). and/or If any of you happen to have a functional v570 CCFL backlight inverter (hitachi invc695) or an LED backlit LCD/driver combo and willing to donate or exchange it for a fully functional V120-22-UN2 model, please let me know. Thanks Quote Link to comment Share on other sites More sharing options...
